Alternative Energy Research And Development – University Activities Revealed

Thu, 29 Jul 2010 00:20:00 +0000

The need of having alternative energy sources was felt by us decades ago. University of Florida Statue and Shell Energy have jointly conducted research on trees and biomass by planting Energy Crop Plantation which is the largest in the United States. Over 250,000 native Cottonwoods and the non-invasive eucalyptus together with different row crops like soybeans sprawl over 130 acres of the Energy Crop Plantation area. The University undertook research in collaboration with some agencies and some local groups who are striving to develop future alternative energy sources independent of fossil fuels. These include The Common Purpose Institute, Shell, Department of Energy of US and various individual groups. As an outcome of their ceaseless efforts, this group of super trees got created.
These energy crops which are also called closed loop biomass are fast-growing crops and are good biomass energy supply sources. This research based project is committed to growing crops and biomass energy supplies processing from fast-growing energy crops or closed loop biomass. The research is primarily on the planting of energy crops which are fast-growing crops called closed loop biomass and processing of resultant supplies of biomass energy. The project aims at developing power wood-pulp plants which provide wood-fiber; providing clean biogas to the industries; ethanol development from plants such as sugarcane; and biodiesel fuel production from crops like soybeans.
The petroleum over-dependence of our nation for power has given rise to an urgent need for an alternative energy source to be developed. Penn State University has undertaken special research to develop anl alternative energy source which is practical and which will not cause an increase in the pollution like petroleum products. Such focused research is taking us to a hydrogen-fuelled economy, when the hydrogen power would be a sustainable and clean and endlessly renewable energy resource. This Hydrogen energy can be obtained from crop plants and water and can be continuously renewed. The Penn University seeks to build this sustainable energy resource within the US’ own infrastructure. This assumes great importance in a situation where the world’s supply of oil peaks and ultimately begins to decline. Fuel cells powered by Hydrogen need to be developed commercially to be used as substitutes or together with conventional combustion engines for motor vehicles.
President Bush recently envisaged the concentrated research and development of fivecenters of Sun Grant for this alternative energy initiative. One such center is Oregon State University with government grants of $80 million to be spread over four years span for this special mission. Thus OSU will be the leader in the research for alternate energy sources since it represents Pacific Islands, the US’ Pacific Territories, and the nine Western states. Various teams of leading scientists are doing specific research on alternative energy. One of the projects which deserves a mention here is how to convert straw-like products into an efficient and renewable source of biomass fuel and yet another project is conversion of wood fibers into efficient liquid fuel. According to Edward Ray, OSU President, this pioneering work being done by the their Sun Grant Center is the direct answer to the challenge given by President Bush for achieving energy independence.

Who Else Wants To Know About Alternative Energy

Sat, 24 Jul 2010 19:13:45 +0000

It is estimated that our natural resources will be completely depleted within the next 150 years. It is because of this that we as a society need to be actively searching for sources of alternative energy.
Alternative energy, whether it is used to replace fuels such as coal, or to reduce our reliance on petroleum based fuels; alternative energy is one of the most important issues facing society today.
The two most common types of alternative energy are:
* Wind power
* Solar power
Both of these alternative energy sources are harnessed from natural resources, and as such are completely free. Only the equipment and technology cost money, and over time as we advance the costs should be reduced.
It is these free sources of alternative energy that we should be pursuing with the most fervency, so that, eventually, energy can be available to all regardless of income. Below we will take a look at these two most common sources of alternative energy.
Wind Power
Wind power, while a free source of alternative energy, would be the most costly type of renewable energy to power our nation. This is largely in part to the fact that we must first place wind turbines across the country, in enough numbers to provide electricity to communities nationwide, even in areas where the wind velocity is not as strong. The cost of building enough of these turbines to harness the wind's alternative energy would be staggering.
Also these wind turbines are very unsightly and would ruin very beautiful and scenic parts of the country. It should also be noted that they only produce power 1/8 of the time that they are running. That is not very efficient, but we are on the right track, things just need improvement.
Another problem I see with wind turbines is the amount of profit many companies stand to make for putting them in. Individuals are making millions off of this and that is just not right when our well-being is at stake.
However, if you're interested in using wind power as your own source of alternative energy, it is a viable option. Many farms and rural communities use these wind turbines to power themselves. In smaller numbers, the cost of building the turbines pays for itself relatively quickly. But wind energy is only one form of alternative energy. Next, we will look at using solar power as an alternative power source.
Solar Power
Solar power is alternative energy derived from the power of the sun. Solar energy is also completely free, except for the cost of installing the equipment necessary to convert the sun's rays into usable electricity. This equipment is becoming less and less expensive every day. Solar power generally ends up paying for itself within the first few years.
The equipment needed to use solar power as an alternative energy source for your home can be bought at virtually any home improvement store, and can usually be installed in just a few hours. If you don't feel comfortable doing it yourself, there are a great number of contractors available who can install your solar panels and generators for you.
Regardless of which type of alternative energy you choose to use in your own home, the fact remains that we must find a renewable source of energy soon, or be at risk of losing the few natural resources we have left to burn. Contact your Congressman today, and ask what is being done to find a good source of alternative energy; and what you can do to help.

Madison Greene is like anybody else. She is interested in saving the planet and finding alternatives for depleting natural resources. She has done diligent research and found a book that teaches you how you can safely make your own alternative fuel at home for less than one dollar a gallon.

All About The Swift Wind Turbine

Wed, 21 Jul 2010 23:39:35 +0000

After having much success installing over 250 home wind turbines in Scotland, Cascading Engineering is bringing the Swift wind turbine to America and Canada.

The company that specializes in plastics, partnered with Swift's Scottish designer, Renewable Devices, to install the revolutionary small wind turbine in the U.S. households.

What sets the Swift apart from other small wind turbines is the reduced noise it produces. In addition, the turbine can be attached to rooftops instead of towers. With it's five blades and "outer diffuser" ring, the company claims vibration is reduced, resulting in only 35 decibels of noise.

With the turbine's seven foot diameter and two fins to help it face the wind, it can rotate 360 degrees and it automatically shuts down in very strong winds. All the elements of its unique design allow the Swift to generate up to 1.5 kW of power in 14 mile per hour winds. This equates to approximately 2000 kilowatt hours per year, which is about a quarter of the electricity consumed by a typical U.S. household.

At a cool $10 000 to be installed, this turbine does not come cheap. However, the upfront cost is significantly lower when state tax credits of $1000 for households, and $4000 for businesses is taken into account.

According to Jessica Lehti, Cascade's senior product marketing manager, this Michigan-based plastics company has already installed 9 Swift turbines in America, and still has at least 25 orders to go.

With a customer base split between residential consumers and businesses, the company is in high hopes that it can sell the Swift to anyone with economic or environmental purposes in mind - even while the economy is in turmoil.

But we disagree with Cascade - not anyone is going to fork out $10 000 just so they can help the environment. Furthermore, the electricity savings realized by households will only cover their investment after 12 years!

Unless people have the money, we are not sure why anyone would want to waste $10 000, when they could easily make their own small wind turbine at home. Although it would be less efficient than commercial ones, if you built enough of them, you could easily make 2000kW hours of power per year.

In fact, many people all over the U.S are making their own power systems at home, and they are showing others how to do it with step-by-step instruction manuals. We have a list of these manuals in our reviews section if you feel the need to make your own energy at home.

To conclude, as much as we like the commercial Swift wind turbine, it is not affordable enough for average households to install. So, until technology and prices improve, we are better off making our own renewable energy solutions at home.

Wind Turbines for Homes – True Facts

Sun, 18 Jul 2010 03:39:29 +0000

Even if it's true that getting energy from the local power company's grid is easier than building one of those wind turbines for homes, the benefit comes when you don't have to pay for a big electric bill, while also becoming more energy independent. With the power driven by wind turbines for homes you can enjoy the advantages of all the modern electrically driven lifestyle without even thinking about the monetary consequences. I dare to say that, if you build yourself one of those wind turbines for homes, using one the best guides available, you could get disconected completely from the grid. Electric bills and fuel bills are rising steadily—but the cost of building wind turbines for homes to get energy is zero, and the cost of installing and hooking up a turbine is steadily coming down as demand rises and more commercial success is realized by various companies producing the turbines and researching technologies to make them ever more efficient. In addition, people are moving away from the traditional power grids and the fossil fuels for personal reasons including desire for greater independence, the desire to live remotely or rurally without having to "go primitive", political concerns such as fears of terrorist strikes on oil fields or power grids, or concerns about the environment. This motivation to get away from the traditional energy sources is the same one that causes people to seek the power of the wind for their energy, giving more business opportunities to profit from wind turbine production and maintenance, which drives their costs down for the consumers. In many parts of the world, homeowners who remain on the grid but who still choose to use wind turbines for homes are eligible for rebates or tax breaks from governments that end up paying for as much as 50% of their total "green" energy systems' costs. There is a lot of energy that we can harness if we only seek to research and develop the technologies needed to do so. We can get away from the old electrical grid by using wind turbines for homes as an alternative energy source.

4 Reliable Suppliers Of Alternative Energy

Sat, 17 Jul 2010 05:54:29 +0000

1. Amelot Holdings is a US based company specializing in development of ethanol and biodiesel plants. It establishes relationships between the researchers and suppliers of alternative energy. The company facilitates joint ventures and mergers between the research facilities and the manufacturers of alternative energy. Thus, there is exchange of information and technology which helps to promote the growth of the alternative energy industry.
2. Environmental Power is another alternative energy supplier. It has two subsidiaries namely Microgy and Buzzard Power. Microgy undertakes research and development in the field of alternative energy. It has developed a cost-effective biogas facility by making use of agricultural and plant waste. It focuses on eco-friendly production of renewable energy like biogas to compare with the standards of natural gas. The biogas is used in combustion engines, and for heating homes and offices. Buzzard Power has an 83MW power facility to generate 'green' energy from coal waste.
Environmental Power has been in existence from the year 1982 and has a long history of development in the field of clean energy. The company has developed and operated municipal waste projects and hydroelectric plants and assisted in clean gas generation and energy recovery. It has a team of experts from the agriculture and finance sectors to manage the business and help its growth and expansion.
3. Intrepid Technology and Resources Incorporated (ITR) processes animal waste into natural gas as an alternative energy resource. America's supply of natural gas is depleting. ITR believes that the two billion ton animal waste produced every year can be used to generate natural gas to tide over the deficit. Their 'organic waste digesters' built close to the sites of the organic waste, produce clean methane gas which is a viable option to natural gas. The company is based in Idaho but plans to expand its operations to the whole country.
4. Nathaniel Energy generates energy from waste matter. The company has devised s system known as Total Value Preservation System (TVPS) which sees the potential of waste materials to generate energy. Industrial waste matter which would have otherwise been discarded or destroyed is being put to optimum use to recover the trapped energy. The production costs towards generation of alternative energy are equivalent to the costs incurred by a company to install pollution control systems and preventions. TVPS is an innovative technology which recovers valuable resources that other processes fail to do.
There are many companies such as those listed above, which use innovative technology to augment our diminishing supply of natural resources by adopting environmentally safe methods to generate alternative energy or renewable energy. There is a need to invest in research towards finding alternative sources of energy as a replacement to fossil fuels. The future of the world depends on industries which can help to achieve this goal. The governments of the various countries need to co-operate in terms of exchange of ideas and information to solve the problems of global warming and environmental pollution. Alternative energy suppliers like the above mentioned companies can play a major role in this process and the government can promote these companies by providing them subsidies.

The Differences Between Clean Energy, Renewable Energy, and Alternative Energy

Thu, 15 Jul 2010 21:29:24 +0000

To many people, the differences between "alternative energy," "renewable energy," and "clean energy," might not be obvious. But each term is unique and has its own individual definition. These three terms are not all exactly the same.

Alternative Energy

When we speak of alternative energy, we refer to sources of usable energy that can replace conventional energy sources (usually, without undesirable side effects). The term "alternative energy" is typically used to refer to sources of energy other than nuclear energy or fossil fuels.

Throughout the course of history, "alternative energy" has referred to different things. There was a time when nuclear energy was considered an alternative to conventional energy, and was therefore called "alternative energy." But times have changed.

These days, a form of "alternative energy" might also be renewable energy, or clean energy, or both. The terms are often interchangeable, but definitely not the same.

Renewable Energy

Renewable energy is any type of energy which comes from renewable natural resources, such as wind, rain, sunlight, geothermal heat, and tides. It is referred to as "renewable" because it doesn't run out. You can always get more of it.

People have begun to turn to this type of energy due to the rising oil prices, and the prospect that we might one day deplete available sources of fossil fuels, as well as due to concerns about the adverse effects that our conventional energy sources have on the environment.

Of all the different types of renewable energy, wind power is one which is growing in its use. The number of users who have some form of wind power installed has increased, with the current worldwide capacity being about 100 GW.

Clean Energy

"Clean energy" is simply any form of energy which is created with clean, harmless, and non-polluting methods.

Most renewable energy sources are also clean energy sources. But not all.

One such example is geothermal power. It may be a renewable energy source, but some geothermal energy processes can be harmful to the environment. Therefore, this is not always a clean energy. However there are also other forms of geothermal energy which are harmless and clean.

Clean energy makes the less impact on the environment than our current conventional energy sources do. It creates an insignificant amount of carbon dioxide, and its use can reduce the speed of global warming - or global pollution.

As you can see, alternative energy, renewable energy, and clean energy are very similar. But it is important to know that there are differences.

There are many actions which can be taken, to help reduce the greenhouse gases in our atmosphere. Some of these steps can be taken in your own home. Many clean energy solutions can can be easily installed, and some kits are quite affordable.

Carbon emissions and other forms of pollution are not only created by heavy industrial factories. They are created in the common household as well. Energy efficiency has become an important aspect of our lives.

It's important to start making changes now; if we want to save our planet for our children, for the flora and fauna of the Earth, and for the future of mankind. Clean energy, to be exact, can make a big difference.

Use Wind Turbines – Save Money And Stop Paying Electricity Bills

Sat, 10 Jul 2010 13:04:58 +0000

What would you do if you could get the electric company to give you money? Well, there are ways to make the electric company and ways that you never have to pay them again. Wind energy is the fastest growing means of alternative energy in the world. Since 2000, the electricity output from wind energy has more than quadrupled. The reason wind energy is popular is because it is clean, efficient, renewable and readily available. Wind turbines have been popping up all over the world. It isn't just homeowners or regular people trying to find alternative energy, but countries and large organizations. There is a demand and people are turning to wind power as a way to meet the alternative energy needs.
Wind power is an interesting idea. There are people who have been installing wind turbines and then taking themselves "off the grid." This means they disconnect themselves from the electric company and never deal with them again. No bills, no notes, no phone calls. Nothing.
This sounds like a great idea, but it requires installing wind turbines, which can be costly. However, there are ways to make some money back. In the United States, there are many states that offer tax breaks by using alternative energy. You will save money if you qualify and you will make your money back faster. There are also some states that allow homeowners to sell the extra energy back. These are "net metering laws." When using the wind turbine, the electricity meter will actually spin backwards. Net metering laws allow homeowners and businesses to be billed only for their net energy consumption as opposed to all of the energy they used.
Net metering helps because customers get full value of the electricity they use. People who use wind turbines might need to use the power company still because wind is intermittent. Over 40 states offer some type of net metering law. Residents should take advantage of these. They can get more information by going to http://www.eere.energy.gov/greenpower/resources/maps/netmetering_map.shtml or contacting the Dept. of Energy Efficiency and Renewable Energy.
As more people begin using wind turbines and the technology progresses, the cost of getting and installing wind turbines is decreasing. This is good news for anyone looking to use wind turbines. Now, there are other avenues to pursue when looking for alternative energy.
Worldwide, wind energy only accounts for 1 percent of the electricity use. However, there are countries that have taken a bigger role in using wind as a viable solution to meeting alternative energy needs. Denmark uses wind turbines for 19 percent of its electricity productions, Spain and Portugal use nine percent and Germany and Ireland use six percent.
Wind turbines also help the environment. Over the course of the wind turbine's lifetime, a residential turbine would be equivalent to planting two trees with the amount of carbon dioxide that would be saved. There are many reasons to get on the wind power bandwagon. They are all worth it. If money is the only thing holding you back, consider all the rebates and benefits you can get from owning a wind turbine. You will make your money back in a few years.

Home Wind Turbines – Cut Your Energy Bill

Thu, 08 Jul 2010 00:31:58 +0000

Energy costs keep sky rocketing with no end in sight. Pollution levels are increasing and our planet is facing a warming trend that could have devastating results. So the question is what can the average citizen do to save money and help the environment at the same time? One great way to help is to lower the amount of electricity your home purchases from the utility company by creating your own power. There are a few ways to do this, and wind power is one of the easiest and more reliable ways to produce energy at your home.

What is a Wind Turbine?

A wind turbine is a simple machine that collects kinetic energy produced by wind currents and converts this energy into power that can be used in the home. Wind turbines are installed on high towers; these towers are usually around eighty to one hundred and twenty feet high. Towers must be high enough to allow the turbine to be above any turbulence generated by objects on the ground. The higher the altitude also results in higher wind speed and in turn, a higher amount of energy can be produced.

How do Wind Turbines Work?

Wind energy is used to create mechanical energy. Turbines have blades that are turned by the wind; these blades turn a shaft to which they are connected. The shaft is then connected to a generator; the mechanical energy is transferred into the generator through the shaft and converts the mechanical energy into electricity. This electricity can then be used in the home for any electrical need. Homes that are using wind turbines to produce power are still hooked up to the power grid. Being hooked up to the power grid allows the home to still have power when wind currents aren't strong enough to produce electricity. Another benefit of continuing to be connected to the power grid is that at the times your wind turbine is producing more power than your home can use, the utility company is absorbing the extra energy and paying you for it. This can lead to very low electric bills. A wind turbine can lower your power bill by 50-80% depending on the amount of wind in your area.

Types of Wind Turbines

There are two main types of turbines: horizontal- axis turbines and vertical-axis turbines. Turbines also come in different sizes as well. Utility companies use wind turbines that can range in size from 100 kilowatts up to several megawatts. These larger turbines are found in groups on wind farms. If you ever drive over the Temecula pass in California, you can see large wind farms along the highway. It is a spectacular site. Small turbines, 100 kilowatts or less, are used at homes. These are place on towers on the homeowner's property and then used to provide some of the energy needed to run the home. Since the size of the tower is quite large, they are usually used in areas where the home is on one acre or more. There are very small turbines on very small towers that may be able to be of use in urban areas or on smaller lots.

The Future of the Wind Turbine

In September of 2008, the U.S. Senate passed a bill that grants a one-year extension of the renewable energy production tax credit. If passed by the U.S. House of Representatives the tax credit would be available until December 2009. Wind power is a viable part of the solution to lessen our dependency on fossil fuels. Wind power is a renewable resource and produces no harmful pollutants. The future looks bright for wind power and hopefully, as a result, there will be a bright future for our planet too.

Using a Residential Wind Turbine System

Tue, 06 Jul 2010 22:31:41 +0000

Using a residential wind turbine seems like a good way to start with a greener way of living and you can save some money at the same time. But is a residential wind turbine suitable for everyone? Well to be honest no, there are some cases where it is really not a good investment to buy a residential wind turbine, sometimes it is just plain impractical to place such a device especially in a urban setting. Residential Wind Turbine When you place a residential wind turbine, for example a Skystream 3.7, to supply electricity, your home will probably rely on your wind turbine and the electricity company. When wind speeds are low the residential wind turbine system will not generate enough power and electricity will be supplied by the electricity company. When there is a higher wind speed, your wind turbine will generate more electricity. Sometimes the residential wind turbine will even generate more electricity than your house needs, when this is the case, the excess electricity is sold to the electricity company. With the right equipment this is done automatically. Is my home suitable for a residential wind turbine? In many urban settings the best kind of conditions will have at least an acre of land around it. Or at least free space, because a wind turbine can also be placed on the roof of a building. The condition of the wind around your house will also be of influence if a wind energy system will be of benefit in your situation. The wind need to be higher than 10 mph if you want to get a significant output from a wind turbine like the Skystream 3.7. But there are residential wind turbines these days that can be placed on the roof of your house so that may be a possibility. When your house is suitable for a residential wind turbine then you can expect to see lower electricity bills. With the Skystream 3.7 for example you can lower your electric bill by as much as 80% if your house has the right wind conditions. Yes this means that you can expect to see a much lower electricity bill, but you will have to invest in a residential wind turbine first. Is buying a wind turbine a good choice? A residential wind turbine is made to last you for 20 to 30 years, this means it will be paid back in the long run. Yes you have initial costs when you buy and place your residential wind turbine. But there are many benefits: - Its is a clean energy source - it is a renewable energy source - it is great for the environment - it will safe you money in the long run The best thing you can do if you are interested in a residential wind turbine system is to inform yourself about your options. Search and learn before you buy. And installing these systems may look simple but getting at least some technical advice before hand is a thing you should keep in mind.

Making A Home Wind Turbine

Fri, 02 Jul 2010 21:51:30 +0000

When one thinks of a home wind turbine, what most probably comes to mind is a gigantic tower with jumbo-jet sized spinning blades. But, with everyone becoming more aware of conserving energy, the technology has advanced so much that it is now possible to have your own small-scale wind turbine at home. Even better is the opportunity for us to make our own, without having to rely on the professionals.

So, how does a home wind turbine make power?

A home wind turbine makes power by spinning a generator. The generator is attached to the rotor, made up of three aerodynamic blades, that is then attached to a tower. To keep the turbine facing the wind, the rotor has a tail, that acts as a weather vain.

The generator is basically an electric motor. As the coils in the motor spin past the magnets, an electric current is produced. The power produced is stored in batteries, which are connected to an inverter to change the direct current to alternating current, which can then be used to power your home. The advancement of motor efficiency, is the reason wind turbines have become so popular for home use.

Depending on your area's wind conditions, the tower can vary in length. If you live near the sea where it is windy, the tower can be shorter, but in low-wind areas the tower needs to be taller to catch as much wind possible.

Over time the blades have improved drastically as researchers developed lighter, stronger, more efficient blades, with the capability of turning even in the lightest breeze. Back in the day, wind turbines had five blades, and looked similar to windmill water pumps, but recently they have moved to three blades, taking the form of over-sized airplane rotors. Like the tower, the blades vary in size, according to your wind conditions and energy requirements.

While so far we have been explaining the typical horizontal axis wind turbine, there is another design that is starting to gain popularity for small-scale projects. It is the vertical axis wind turbine or VAWT. Very different to the standard horizontal axis turbine, the VAWT spins on a vertical axis, and almost looks like a waterwheel put on its side. Since the VAWT tends to operate low to ground, it needs far more wind to make it turn efficiently, so it is not the ideal option for homeowners or small businesses. The VAWT has also been accused by ecologists of interrupting and harming various migratory birds, making it less attractive for green enthusiasts.

Before going out and installing a wind turbine, it is best to ask yourself the following questions:

- How big is the property?

Wind turbines generally operate better in large areas that cover an acre. This is because wind flow is not deflected by any nearby buildings.

- What is the average wind speed?

The recommended wind speed should be at least eleven miles per hour, but if that isn't the case then you may have to use a taller tower and larger blades to catch higher altitude winds.

- What else can I use the wind turbine for?

If you could use the turbine for other purposes, such as pumping in water from outside, then it may be useful than you think. This is the reason you see so many windmills scattered over farms - they help pump water from reservoirs to the farmhouse.

- Does my house need a constant power supply?

This is why so many people want to get a small wind turbine in the first place - to keep the house powered during blackouts, and prevent economic losses. Although the wind turbine may not power the house all the time, it's stored power can be used in emergencies, when the utilities are just not enough.

Answering these questions will give you a good idea of how much power you need, how big the tower a blades need to be, and how much it would be worth investing to start making your own power at home.

The great thing about technology is that it is always improving. So much so that motors have become smaller, efficient and cheap enough for us to attach a few small turbines right on the roof, and produce the same power as a larger turbine on a tall tower.

Although professional home wind turbines can run into several thousands of dollars, it is possible to make your own for a tenth of the price, with components found at home and your local hardware store. Furthermore, the U.S. offers both state and federal tax credits that you can use to offset the installation cost. So not only will you reduce your electricity bill, but also your tax at the same time.

Investing In Alternative Energy Stocks – New Way To Boost Your Profits

Thu, 01 Jul 2010 13:55:13 +0000

Having a diverse portfolio is something investors will explain is important. This way, you don't end up putting all of your money in one place and you can make money through many different avenues. One of the areas people are considering is investing in alternative energy stocks. This may sound like a risky venture, but any time you invest your money there is no guarantee you are going to get a positive return. Alternative energy is the wave of the future and with the rise of new companies, this could be a very profitable market. Don't turn your back too quickly because many investors aren't.
Analysts’ forecasts are favorable in this area. They say by 2013 it could become a $13 billion dollar industry. There are many ways to look at that. The bright side is that if you find a nice little start up company, you might have on your hands the next Microsoft. That means this tiny company became a conglomerate overnight with a beat on the market. Of course, that is always the dream and rarely happens. Realistically, these small companies could hold lots of potential, especially when a form of alternative energy is picked as the course of the future.
There are a few reasons why investing in alternative energy stocks is a route to consider. The first thing is that more and more companies are researching how to use alternative fuels. There are many on the market already such as ethanol and biodiesels. With gasoline and oil prices being so high and the United States' dependency on foreign oil, companies want to help eliminate these problems. Alternative energy is also less harmful to the environment. Companies are looking at ways to get renewable energy resources or ones that provide fewer emissions than are currently being used.
However, there is the flip side to investing in alternative energy stocks. It is such an uncertain area and there is no right way to go. You could end up looking at hundreds of different stocks wondering if geothermal is the way to go or is it ethanol companies or solar power. And, that is just three alternatives energies and not counting the other ways companies are trying to find alternative energy. If you take a chance on solar power, it may turn out that oceanic thermal energy was the way all along. There is no real answer.
Anyone considering investing in alternative energy stocks needs to consult with a financial advisor. Many have experience in this market and know more about this sector than anyone you could ever meet. They are going to show you which companies have the best upside and what alternative energy has the best chance at becoming the main power source of the future.

Evance: International wind turbine suppliers

The wind power industry is advancing in the exploration and development of better and more efficient ways of converting wind power into useful energy. Primitive techniques of harnessing the power of the wind already existed many centuries ago and today, modern wind turbine suppliers aim to better their designs and technology to meet current and future energy demands.

ISKRA Wind Turbine suppliers recently announced its decision to change the company name to Evance. The company was already established in the wind generator UK market and is fast expanding into the international market. As a leading manufacturer of small wind turbines, ISKRA, now Evance, anticipated a potential trademark dispute concerning the name ISKRA. The company has released a range of reputable wind turbines and a new corporate look and feel suits its rapid international expansion and production of new, innovative small-scale wind turbines.

Evance is an appropriate amalgamation of the terms advance and energy, illustrating Evance’s role as pioneers in the field of renewable energy generation, in particular wind turbine technology. The rebrand was announced earlier this year in May, and the timing of this brand-evolution strategy was carefully calculated to accompany the release of the new smaller, more efficient Evance wind turbine. Evance is confident that their latest wind energy system, called the EVANCE ISKRA R9000, will do well in the international and UK wind generator markets.

Renewable Energy in Florida

admin — Mon, 28 Jun 2010 19:10:15 +0000

Florida holds great potential in developing renewable energy utilizing its climate and natural resources. The sunshine state has fantastic solar energy opportunities boasting investment in large-scale solar energy projects and private households installing solar panels to generate electricity and heat up water.

There are many wave energy opportunities in Florida, the Straits Current and Gulf Stream Current are only a few miles away from the shorelines in the south and eastern parts of the state. Those can be used to generate electricity from tidal wave energy.

Light winds make wind energy the least attractive when it comes to renewable energy in Florida, at the same time new technologies in wind energy do give the possibility for home owners to install wind turbines privately and generate their own power in windy areas.

The current government of Florida is pushing for reforms in the energy sector, particularly after recent fossil fuel disasters such as the Deep Horizon explosion and the huge oil spill that followed after it. The ecological impact of catastrophes like this had triggered a large wave of awareness about the ability of states and countries to utilize their natural resources for the benefit of creating clean and sustainable energy. The Obama administration is also pushing towards a new energy bill to boost renewable energy investment all over the United States and get rid of "America's addiction" to oil. This energy bill will have a direct influence on new energy laws passed on a local state level.

Florida has all the potential to become a leader in solar energy attracting large-scale investments that can help the state to create additional new jobs in the energy sector, help meeting the electricity demand during high peak times through out the year and enjoy the environmental benefits that derive from clean, sustainable, renewable energy.

Geothermal Energy – The Other Renewable Energy

admin — Thu, 24 Jun 2010 00:21:24 +0000

When it comes to renewable energy, wind and solar are the media darlings. Every time I hear renewable energy mentioned on TV or radio, it's always wind and solar. If geothermal is mentioned, it's an afterthought, and said almost under the announcer's breath. Why? Given the immense importance of the United States' (and the world's) energy future, this is not the time to complacent. The stakes are too high as global warming looms large over our collective heads and the era of easily-accessible fossil fuels winds down. Our transition away from hydrocarbons to renewable energy is way too critical for any of us not to be informed about all available viable options.

Why you ask? Because informed and motivated citizens equates to political action which in turn starts the flow of money for development. We are all influenced by the media and public opinion. This is especially true of politicians. Why do you think they spend so much money doing polling. It is their way of determining what we, the public, want from them. We should also be wanting geothermal energy.

Solar and wind are viable alternatives but they have their detractions. So does geothermal. But given the facts, geothermal, at the very least, deserves equal billing. Actually, the US is already the world's largest producer of electricity from geothermal. A fact that few, outside of the geothermal industry, know. According to the Geothermal Energy Association, "geothermal power makes up a total of 3.15 gigawatts (GW) of installed capacity in the United States, its largest producer, and more than 10 GW worldwide." So, while geothermal gets fewer headlines and media attention it actually supplies more mega-watt hours of electricity than either wind or solar.

Geothermal power plants provide what is known as base load power i.e., they produce power at a constant rate, just like coal-fired, natural gas, hydroelectricity or nuclear power plants. Wind and solar energy are generally considered intermittent power sources. That doesn't mean that wind and solar are unimportant, we need all three - four if you add in hydropower. Geothermal resources are not available everywhere, at least not for power plants. Home geothermal heat exchangers are used almost anywhere.

Fortunately, in the US, geothermal development is, albeit quietly, on the rise. According to the Geothermal Energy Association, "geothermal power projects grew 46 percent last year. That's up from about 30 percent growth in 2008." Furthermore, "If all of the planned projects were to go forwards as planned, an unlikely scenario, the total U.S. geothermal capacity would reach today's worldwide capacity of 10 GW — enough to meet the power needs of an average 10 million people or supply 25 percent of California's 2008 power consumption. But advocates believe the ultimate potential to be much larger still."

As mentioned, not all of these planned geothermal projects will go forward. Nonetheless, there's a quite a ground-swell of geothermal exploration and development happening in America and it's happening right beneath our feet, literally and metaphorically.

The bottom line is, it is time geothermal energy started getting it's due. When, and if, you ever talk about renewable energy keep this article in mind. Tell your local politicians you care about funding geothermal exploration. When you see a news report about green energy, send them an email to mention geothermal next time. Start a groundswell. It's our future and the stakes are high. - David Brooks

Alternative Energy Development in Japan

admin — Fri, 18 Jun 2010 05:23:30 +0000

Japan is a densely populated country, and that makes the Japanese market more difficult compared with other markets. If we utilize the possibilities of near-shore installations or even offshore installations in the future, that will give us the possibility of continued use of wind energy. If we go offshore, it's more expensive because the construction of foundations is expensive. But often the wind is stronger offshore, and that can offset the higher costs. We're getting more and more competitive with our equipment. The price—if you measure it per kilowatt-hour produced—is going lower, due to the fact that turbines are getting more efficient. So we're creating increased interest in wind energy. If you compare it to other renewable energy sources, wind is by far the most competitive today. If we're able to utilize sites close to the sea or at sea with good wind machines, then the price per kilowatt-hour is competitive against other sources of energy, go the words of Svend Sigaard, who happens to be president and CEO of the world's largest wind turbine maker, Vestas wind systems out of Denmark. Vestas is heavily involved in investments of capital into helping Japan expand its wind turbine power generating capacity. It is seeking to get offshore installations put into place in a nation that it says is ready for the fruits of investment into alternative energy research and development.

The Japanese know that they cannot become subservient to the energy supply dictates of foreign nations—World War II taught them that, as the US decimated their oil supply lines and crippled their military machine. They need to produce energy of their own, and they being an isolated island nation with few natural resources that are conducive to energy production as it is defined now are very open to foreign investment and foreign development as well as the prospect of technological innovation that can make them independent. Allowing corporations such as Vestas to get the nation running on more wind-produced energy is a step in the right direction for the Japanese people.

The production of energy through what is known as microhydoelectric power plants has also been catching on in Japan. Japan has a myriad rivers and mountain streams, and these are ideally suited places for the putting up of microhydroelectric power plants, which are defined by the New Energy and Industrial Technology Development Organization as power plants run by water which have a maximum output of 100 kilowatts or less. By comparison, "minihydroelectric" power plants can put out up to 1000 kilowatts of electrical energy.

In Japan, the small-scaled mini- and micro-hydroelectric power plants have been regarded for a considerable time as being suitable for creating electricity in mountainous regions, but they have through refinement come to be regarded as excellent for Japanese cities as well. Kawasaki City Waterworks, Japan Natural Energy Company, and Tokyo Electric Power Company have all been involved in the development of small-scale hydroelectric power plants within Japanese cities.
