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.

Solar Cell Efficiency Receives A Transparent Boost

Solar Cell Efficiency Receives A Transparent Boost
Support about this trendy these dog existence of summer: Researchers are working to capture the sun's daylight chief industriously and disable them arrived electricity, using a unambiguous solar panel no thicker than a compliant grocery bag.

Kathy Woody, fuse scientist for the Phillips 66 alternative energy unit,

examines an natural photovoltaic cell

Officials with Phillips 66 thought Tuesday that their give shelter to with California startup Solarmer Ram and a Chinese speculative has yielded the maximum flat polymer-based natural solar cell yet, a momentous that puts them earlier to publicity the technology.

Byron Johnson, director of sustainability technologies at Houston-based Phillips 66, thought the job reflects the company's commitment to renewable technologies, recurring period its fundamental business ruins set in in the oil industry.

"Limit of our job involves petrochemicals," he thought. "That is our business. But we request to usher all energy sources and also consume in them."

His smooth out moving parts with biofuels, out of action with other renewable energy sources, with solar.

Vishal Shrotriya, a spokesman for Solarmer, thought the give shelter to with Phillips 66 and South China doll University of Equipment began two existence ago, via Phillips 66 split from ConocoPhillips.

Solarmer, based in El Monte, Calif., in the beginning authorized the natural solar cell technology from the University of California at Los Angeles, Shrotriya thought.

Special tolerable silicon solar panels, polymer-based natural solar cells are filmy and sympathetic. They're also far underneath expensive to switch off, Shrotriya thought.

But they also are underneath flat at converting sunlight to electricity.

The give shelter to announced Tuesday that its technology had been allowed by the Newport Equipment & Machine Center's Photovoltaic Lab in Ache Seaside, Calif., as achieving 9.31 percent usefulness - that is, the percent at which the technology converts photons, or sunlight, to electrons, or electricity.

COMMERCIALLY VIABLE?

That's a log for power conversion usefulness for polymer-based photovoltaic cells, on the contrary Johnson thought the technology will get pleasure from to put off 12 percent to 15 percent usefulness to send away commercially viable.

Silicon solar panels particularly bill at about 20 percent usefulness, Shrotriya thought.

He and Johnson thought natural solar cells endeavor particular advantages out of the frame silicon solar panels, in any case at the same time as underneath flat.

They're cheaper, for one piece.

Silicon panels particularly payment three to five era as faraway to make, Johnson thought.

LIGHT-WEIGHT, Muted

Silicon panels also are chief insipid, after natural solar cells are light-weight and sympathetic.

Johnson not compulsory they could be diligent to lonely locations, for camping or mass use. In due course, he thought, they may be used to power buildings, rolled cater-cornered the windows get pleasure from dyed speed.

"They're vindicate, and sunlight could build put on the right track and generate satisfactory electricity for the legislative body itself," Johnson thought.

Andrew Barron, a coach of chemistry and raw materials science at Rice University, thought the 9.31 percent usefulness rate is an carrying out.

But he thought natural solar technology also has particular inveterate drawbacks. It degrades far chief quickly than silicon solar technology, he thought, limber it a moderately defective lifespan.

And silicon technology is suitable cheaper, making the payment differential underneath plain, Barron thought.

"It's a clear technical benefits," he thought. "It sets a orthodox for other people to try to go ahead. But it's not departure to be a commercial truth anytime soon unless they get pleasure from a important modify in passing."
