Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

5 Reasons Were Thankful For Solar

5 Reasons Were Thankful For Solar
That's Right-we're Using A Picture Of A Bavarian Town For Our Thanksgiving Post.

Here in the U.S.A. we're gearing up to celebrate Thanksgiving. As the name attests, it is a holiday that calls us to give thanks. And we cannot do so without paying mention to solar power. You know us: we can talk the merits of solar PV all day. But in the interest of time, here are a few reasons we're thankful for solar...

1. SOLAR PUSHES US TO FIND BETTER SOLUTIONS

In a quiet town in southern Bavaria, the sun helps produce 500 percent more energy than inhabitants use. That, my friends, is no typo-"500 percent". Much like any grid-connected system, surplus power is sold back to the utility. While impressive in and of itself, it's not without concerns. Mainly, how do you maintain network stability? In an effort to answer this question, A"UW (their regional utility) and Siemens are testing out their smart grid...

2. IT MAKES GOOD BUSINESS SENSE

More and more businesses are looking to go solar, not only for their bottom line, but to be better stewards of the environment. One of the latest to make headlines is Ford. They've announced a pilot program where they'll install solar and wind systems to power buildings, charging stations, and lot lighting in four of their dealerships that sell a lot of hybrid/electric cars. An interesting twist: the wind sails will be branded, so while their main job will be harnessing power, they'll be marketing on the side.

3. SOLAR GIVES HOPE TO DEVELOPING COUNTRIES

For many years, it was assumed solar was out of reach for developing countries. But thanks to improved technologies, that is no longer the case. Today, solar helps provide electricity, even when the sun goes down-not only improving lives, but even helping to save them. Because of this, many of these countries are building policies and infrastructures that attract investors-together, they're installing some amazing systems.

4. JOBS!

Those of us in the business of solar installation have long argued that solar power produces jobs-lots and lots of jobs. Of course, being in the industry, we tend to lose a bit of traction on that argument. We are, after all, a bit biased. Well, the U.K. Energy Research Center decided to look into those claims (apparently, the argument crosses the pond). Their conclusion: the green sector would create more jobs than the fossil fuel sector. That's even taking into consideration the jobs lost by phasing out fossil-fuels, as well as a world without green policies.

5. IT'S ABUNDANT

It seems so obvious, but solar is a free, abundant resource. That, alone, is worthy of our gratitude. A new report by Environment America puts it in perspective-mainly, enough sunlight reaches the United States every year to power the entire country 100 times over.
