Countries like Denmark and Spain have already successfully harnessed wind power to supply a portion of their electric power. In London, a vast wind farm expected to become the largest in the world has already begun construction, a physical manifestation of the country’s efforts towards encouraging the renewable energy sector. Elsewhere in the United States are several wind farms established for power generation, such as those in Pampa, Texas and in Fond du Lac County in Wisconsin. In Wyoming, there is the Happy Jack Windpower Facility that already began its commercial operations in September 2008.

Another renewable energy source is also being used to generate power and for other practical purposes as well—solar power. In states filled with sunshine the whole year through, such as California and Nevada, solar thermal power plants are being constructed with the aim of supplying power to a large percentage of households. However, the largest photovoltaic plant in the world is found in Germany and is expected to become operational in 2009. Several communities in the United States are also implementing plans of purchasing and installing their own photovoltaic farms to supply renewable energy to its households.

Many places all over the world are also harnessing geothermal energy for power supply. In the United States, the latest projects of this kind have been initiated in Beaver County, Utah and in New Mexico. The former has a geothermal power plant called Thermo while the latter has just begun construction on the Lightning Dock Geothermal Power Plant.

Wave power is also being tapped as potential source of renewable source, with the opening of a large wave farm in Portugal in September 2008. This first of its kind facility is expected to generate more than 2 MW of electricity. In Oahu, Hawaii, the US Navy has funded and taken active participation in the development of a wave energy technology expected to generate about 1 MW of electricity.

And elsewhere in the world, car manufacturers, legislators, and private individuals have taken interest and commitment to reduce carbon dioxide emissions through the use of more energy efficient automobiles. Most of these vehicles are also capable of using the biofuel ethanol, which is certainly affordable and produces no pollutants into the atmosphere.

With most of the countries in the world and environmental organizations pushing for the use of renewable energy resources and for the development of supporting technologies, there is an expected trend of consumer preference toward renewable energy supply. Because of these, it is also expected that the renewable energy sector will continue to increase and expand with more investments from capitalists all over world. With these developments, the goals of reducing the world’s dependence of fossil fuels and enjoying cleaner environment are slowly reaching realization.

The number of parts in an electric car is also less as against other hybrid cars or cars that run on gas. The noise from electric cars is almost negligible. Basically, an electric car is made up of a simple frame, wheels, an electric motor, car battery and an electric on and off switch. The engine of the electric car is made up of a series of batteries that are attached to an on and off switch and it is in turn, attached to a motor that is electrically operated. Obviously, the electric motor drives the wheels and sets the car in motion.

The amount of electricity that goes into the motor is controlled to drive the vehicle in a controlled manner. There are solar cars available that convert solar energy into electricity. The electricity that is stored within the battery of an electric car can be generated from any source, apart from solar, like nuclear, natural gas, coal and petroleum.

Since electric cars have a low center of gravity, the initial acceleration is quite rapid and can be handled quite easily. But, the fact of the matter is, that the lithium ion batteries used in cars are very expensive making the overall price of the car expensive and these batteries have to be replaced once in three or four years. In addition, the charging of the battery takes almost three or four hours to fully recharge and therefore needs prior planning, if the electric car is to be used for longer distances.

This also means that the batteries can be charged only from the initial point of journey because there may not be too many charging stations on the way. People also feel that the electric cars are not most suitable for driving long distances and can be nightmarish, if the car runs out of battery or in the midst of busy traffic.

Normally, an electric car offers the equivalent of twenty miles per gallon and the cost to run a mile is nearly three cents. Further more; there is no expenditure on tune ups, oil changes and the like in an electric car. So, people who are environment friendly and want to paint a greener world can opt for an electric car.

The choice would not only be appreciated by others but it would also fill the pocket of the owner because it saves a lot of fuel in the long run. Even though man affords to purchase oil what with soaring oil prices, oil is a depleting natural resource and it is our duty to save this resource for our future generations.

Even though the government still has a long way to go to get these alternative fuels many Americans have already learned the chemistry to producing these fuels. A recent study by a Pacific Northwest university said that they cannot find a way to make the fuel as good as gas made from oil. Gas will only go so far but the bio diesel will go a long way because it is cheap to make and isn’t hard to convert motors to run on them they just have to already be a diesel motor.

Biofuels are made by using matter from the environment to make a usable fuel to burn. These biofuels are better to use then the fossil fuels that we burn every day. The bio fuels need to be able to use in cars or vehicles because that is where most of out fossil fuels go to. They need to make a way or fuel that can run in any car and can make it at a very cheap rate.

Even though it has a long way to go till everyone is using these there are still a few people in the United States who have these bio fuel labs in the garages at home. The study done up north by a university still cannot find out why they can’t make a small amount of bio fuel and that is because you don’t have the right properties. You are probably trying to use something with no significant bio value at all.

Even though the oil has been though in the stock exchange does not mean that we Americans cannot make something that can be used as an every day alternative, dropping all the oils prices are not going to do it because then people will continue to use them. The people just need to take the matter into their own hands and make something that can be used every day as a fossil fuel alternative. It isn’t hard people are already using bio diesel every day. Nothing stopping them from making their own. The government knows how to make these fuels they just don’t want to because they want to keep stealing all our money even though they are the ones printing the money.

First, there are many types of electric cars you can choose from, but all of them use an electric motor that runs on batteries that you recharge. The more batteries you have, the longer you can drive your car. Electric cars come in all different sizes and performances. They are aerodynamically more efficient than gasoline powered cars because electricity stored chemically is lighter than electricity stored electrically.

Another very advantageous fact about electric cars is that they emit virtually no greenhouse gases into the air and thus run much, much cleaner than many other vehicles. Greenhouse gases contribute to the depletion of the ozone layer that has led to global warming. Electric cars that run on batteries alone produce no pollution at all and thus are very environmentally friendly.

How far can you drive on an electric car’s charge? The amazing fact is that electric cars can usually travel for about a hundred miles before needing a charge. The batteries generally need charged overnight and there is a gauge that can tell you how much power you have left. They are perfectly fine for city driving and those who don’t have to go long distances on a regular basis.

This next fact about electric cars may amaze you – I know it did me! Some people believe that an electric car can’t go very fast. But the fact is that electric cars have been clocked at over one hundred miles per hour and can go from zero to that in less than nine seconds! This is because electric motors have a very high torque which allows them to accelerate quickly and travel faster.

There are many more facts to be found out about electric cars such as their price, their range, their availability, and their benefits. Finding out these facts is easy. If you are thinking about buying an electric car, do your research and find one that fits your lifestyle. Most car companies produce at least a hybrid type of electric car that runs on both gasoline and electricity, but you can also find total electric cars if you know where to look. Just get the facts and then get on the electric car bandwagon. You may just find out you like it there!

Ethanol can be distilled from corn, sugarcane or even straw and other cellulosic plant materials such as wood chips or grasses. Biodiesel is produced from vegetable oil crops such as palm, soybeans or rapeseed, or animal fats and leftover restaurant grease.

High oil prices, technological advances, concerns about energy security and the environment, and efforts to revitalize rural economies have all intersected to drive the biofuels boom. Ethanol has been used as a gasoline additive or stand-alone fuel in the United States and Brazil since the 1970s, but in recent years there has been an explosion of interest, resulting in substantial investment and steeply increased production.

Biodiesel is relatively new in the U.S., but has attracted strong interest and investment as well. There are 113 ethanol plants producing today in the U.S., with a capacity of 5.6 billion gallons per year or 365,000 barrels per day (bd).

Another 84 ethanol plants are either under construction or expanding, which could add another 6.1 billion gallons of annual production capacity (400,000 bd) in the next few years. A barrel of ethanol contains 3.54 million British Thermal Units (BTUs) of energy, while a barrel of gasoline contains 5.25 million BTUs. This means that a gallon of ethanol only provides about 70 percent of the energy that one gets from a gallon of gasoline. A state-of-the-art ethanol plant today can convert a bushel of corn into about 2.8 gallons of fuel ethanol. Two decades ago, this figure was closer to 2 gallons.

n the United States, blenders of ethanol receive a 51 cent-per gallon tax credit for every gallon of ethanol used in gasoline; for biodiesel, the equivalent credit is .00 per gallon. In 1980, the U.S. consumed a grand total of 11,000 barrels of ethanol per day. By early 2007, that demand had reached about 400,000 barrels per day, or over four percent of the total gasoline market by volume.

Current federal legislation requires 7.5 billion gallons (490,000 bd) of biofuel use by 2012. The Bush administration recently proposed a target of 35 billion gallons (2.3 million bd) of renewable and alternative fuels by 2017-a goal that would likely require major advances in cellulosic ethanol technology.

In 2006, the ethanol sector consumed nearly 2.2 billion bushels of corn-about 20 percent of the total U.S. harvest of 10.7 billion bushels. Ethanol can be produced from non-food crops, such as switchgrass and straw. But this approach can’t yet compete in the marketplace. There is currently intense interest in making this process-”cellulosic ethanol”-commercially viable.

The US biodiesel industry is much smaller than the ethanol industry. Current annual production is estimated at 250 million gallons (16,000 bd), although it is growing quickly. Europe is currently the world leader in biodiesel production and use. Annual production is currently over 1.5 billion gallons (100,000 bd) with substantial new capacity under construction.

David Murray may drive the quietest car in North Texas, powered only by a small electric motor, and not creating any emissions. “The most common question I get is, ‘Is this an electric car?’ and then they’re like, “Is it a hybrid?’ Nope, it’s a real electric (car),” Murray said. When his car is low on fuel, Murray simply plugs the power cord into the nearest outlet. “Yeah, just plug it in here. Just a regular old extension cord,” Murray said. The self-described computer geek from Kennedale bought the 1993 Eagle Talon from a junkyard for just 0. “First thing I did when I got the car home was pull the engine out,” Murray said. He then spent about 00 more to convert the gas-guzzler to run on electricity alone, doing all the work himself in his garage at home. “I bought the electric motor and I was like well, I gotta figure out a way to couple it together with the original transmission,” he said. The car can hit 55 mph, driving right past the high prices at gas stations. “I hear people complain about them at work all the time. I just grin,” he said. Murray spends just per month on electricity to charge the batteries — enough to go about 300 miles. “I don’t even look at the gas prices,” Murray said.

Ethanol is an alcoholic fuel prepared from the sugars found in grains, such as corn, sorghum, and wheat, along with potato skins, rice, sugarcane, sugar beets, and yard clippings. Biodiesel is prepared from vegetable oils, fats, or greases. Biodiesel fuels can be used in diesel engines not including any changes in them. It is the best ever budding substitute petroleum in countries such as United States. Biodiesel is a renewable source of energy and thus is safe, recyclable, and decreases the release of the majority air toxins. It is no doubt an eco-friendly version of diesel.

It is frequently asserted that biofuels are carbon-neutral as they release CO2 when burnt that was previously present in the atmosphere. There is a considerable CO2 discharge from the refinery and distillery processes required to make biodiesel or bioethanol, as well as for transport, the use of ranch machinery, and manure production. Biodiesel, in particular, is connected to high releases of the powerful and long-term greenhouse gas nitrous oxide, released by microbes when nitrogen fertilizers are applied to soils, and also throughout the manufacture of nitrogen fertilizers.

There are two main types of biofuels for transport:

Bioethanol, which is an alcohol derivative of sugar or starch, for example from sugar beet, cane or from corn, and

Biodiesel, derivative of vegetable oils, for example from rapeseed oil, jatropha, soy or palm oil.

United States is the world’s biggest bioethanol manufacturer, and this books for 99% of their biofuel for road transport. The region is, as of yet, the world’s chief biodiesel creator, and prefer biodiesel than bioethanol. It is discovered that ethanol has preferably less greenhouse gas releases than petrol.

Among the biofuel crops grown in Europe and the US, biodiesel is usually measured to be more energy competent than bioethanol. A few biodiesel crops, such as oilseed rape are developed with huge magnitude of fertilizers, which compensate for a lot of the greenhouse gas reserves.

Biofuels are considered to be the best way to reduce green house gas emissions and alternate to the pollutant fossil fuels. But recently, according to Nobel Laureate Paul Cortzen findings, some of the most commonly used biofuels Bioethanol from corn and bio diesel from rapeseed releases Nitrous Oxide (N2O) is contributing much more to the global warming than the fossil fuels are contributing right now. Processing of biofuel form algae has been tested that it captures large amounts of CO2 and N2O available in the atmosphere( 40% in a course of full day and 80% in sunny days) and an acre of algae can produce enough oil to make 5,000 gallons of biodiesel in a year.

According to my point of view biodiesel and bio ethanol from rapeseed and corn is not only adding to global warming but economically it cannot be sustainable because its one of the main sources of edible oil. Ethanol demand can threaten the food prices. A recent study conducted by Center for Agricultural and Rural Development at Iowa State University reveled that considering the high-price crude oil scenario, U.S. ethanol production could reach 30 billion gallons by 2016, consuming more than half of U.S. corn, wheat and other coarse grain production and triggering higher meat prices for consumers, reduced production across-the-board for all segments of the meat sector, and even greater reductions in grain and meat exports. Taking in review the sustainability and economic factor biofuel from Alga culture seems to be most promising fuel for future.

1. Availability – It is renewable. Unlike fossil fuels, biofuels can be easily produced from raw agricultural materials. These facts ensure that the reservoir of fuel will never end, and that we can keep producing it, like we produce our food.

2. Price – since the reservoir is virtually unlimited, we can assure that as time goes by, the oil prices will increase duo to the increase in demand/production ratio, while the biofuels prices will decrease duo to the progress in agriculture science and techniques. In a few years from now, it is almost certain that biofuels prices will be much lower than fossil fuels, so the sooner you start using it, the better.

3. Independence –Biofuelsare easy to produce, and propose a new prospect to fuel consumers – unlike today’s when huge company controls the fuel industry and supply, making the small consumer a slave to their will, biofuels will allow individuals and small manufacturer to get into this business and increase the competition. This is good both to the manufacturers and to the clients.

4. Healthier – biodiesel and ethanol are much safer than biofuels – they are much better to the environment, and have a great implication regarding global warming and air quality. If you care about the air that you and your children are breathing, you must take it under consideration.

5. Better to the engine. Biofuels are not only healthier to the environment, but also much better to the engines. Much research done by the automobile industry shows that biodiesel and ethanol increase the efficiency of the engine and it life span.

6. Have good political implications. At present, oil producing countries enclose a huge power in their hands, allowing them to take advantage of their power to harm other countries, and jeopardise world peace. Crossing to a different fuel source will dramatically reduce the pressure of oil deficiency, allowing many suppressed countries to flourish.

I hope that these reasons will capture your attention, to do something in that direction, making the world a better place to everyone.

Usually a pioneer in new technologies, the United States is far behind when it comes to the use of biofuels.  Much of Europe uses these biofuels, with many countries generating at least a quarter of their heat from this source.  Sweden heats over thirty five percent of homes, businesses, and other buildings using biofuels and operates boilers that work at an astounding ninety percent efficiency.  When considering the large strides taken by so many other nations, it is hard to comprehend why we have not taken similar measures.

Political motive aside, however, it is rapidly becoming common knowledge that we must wean ourselves from fossil fuels and biofuel is by far the most commonly accepted alternative.  Safe, clean, and sustainable, biofuel can be used in existing systems with only minor alterations, making it a cheaper and more fluid transition for the millions of Americans who would need to upgrade automobiles and heating systems.  The question is not whether we need to wean ourselves from this dependence, but rather how to go about making the change.

Many public transportation systems and college transport vehicles have already made the change to biofuel.  While this is only a small step, it shows the public that biofuel is reliable and effective without causing need for fossil fuels.  The consumer market, however, seems to be easier to convince than many in the energy production industry.  Many facilities seem to ignore the concept altogether, even as emissions standards change in an attempt to create new methods of energy production.  Tax incentives for consumers offer great encouragement in a struggling economy, but the idea is only sustainable if there is a constant and easily accessible source of biofuel in every area of the nation, presenting problems for early adopters of the new technology.

The attempted weaning of the United States from fossil fuels to biofuels will need to undergo a shift in its targets to be largely successful.  While attempts to start with consumers and end users have been moderately successful, it is industrialists, businesses, and energy producers that must be encouraged to begin implementing the fuel en masse, creating a viable market and the consensus among consumers that the fuel will be available universally.  When this is achieved, the consumer market will be much more receptive to a cheaper and cleaner source of fuel.
