Electricity derived from fusion reactions similar to what takes place in the sun could help sate humanity's growing appetite for green energy, according to lab officials.

Imagine if all you had to do to charge your iPod or your BlackBerry was to wave your hand, or stretch your arm, or take a walk? You could say goodbye to batteries and never have to plug those devices into a power source again.

William Yuan, a seventh-grader from Portland, OR, developed a three-dimensional solar cell that absorbs UV as well as visible light.

New solar dish harnesses power from heat - at a size and cost that make soaking up the sun even more attractive.

Scientists must start dumping carbon dioxide into the deep ocean to see whether it provides a safe way of tackling global warming, a leading expert on climate change has said.

The sun isn't always up, the wind doesn't always blow, and the tides come and go, all of which leaves those running the energy grid with the challenge of evening out the power supply. Fortunately there are options being pursued for storing power.

Beacon Power produces a novelform of power storage in the shape of large carbon fiber flywheels, which spin at 16,000 revolutions per minute. At one meter in diameter and 8,000 lbs, each wheel can provide 100 kilowatts of electricity for 15 minutes.

As the international search for ways to remove carbon dioxide and other greenhouse gases from the environment intensifies, a team of scientists has identified a process by which marine organisms influence the amount of atmospheric carbon the sea absorbs.

Researchers in Spain have proven that special materials can be designed to produce an acoustic cloak - one that can make sound waves flow around an object.

Methanol Fuel Cell Membrane MIT engineers have improved the power output of one type of fuel cell by more than 50 percent through technology that could help these environmentally friendly energy storage devices find a much broader market.
