Researchers are developing a technique that uses nanotechnology to harvest energy from hot pipes or engine components to potentially recover energy wasted in factories, power plants and cars.

While we’ve looked at the development of solar cell technologies that employ nanoscale 3D structures to trap light and increase the amount of solar energy absorbed, MIT researchers have now used 3D on the macro scale to achieve power output that is up to 20 times greater than traditional fixed flat solar panels with the same base area.

Qatar will build a smart national power grid to facilitate intelligent and reliable energy distribution as part of its World Cup 2022 strategy, said a senior official.

A family for the last ten years has been living without worry of power cut during summer is sharing with us their secret.

Speaking at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society, Ibrahim Khamis, Ph.D., described how heat from existing nuclear plants could be used in the more economical production of hydrogen, with future plants custom-built for hydrogen production. He is with the International Atomic Energy Agency (IAEA) in Vienna, Austria.

Continuing with the journey towards power saving, Philips Electronics Co., Ltd. Vietnam (Philips VN) has just come to Luu Ngoc and Cao Chuong hamlets (Tra Linh district, Cao Bang).

Fuentes De Andalucia, Spain - A unique thermosolar power station in southern Spain can shrug off cloudy days: energy stored when the sun shines lets it produce electricity even during the night.

Tanzania probably doesn’t come to mind when you think about solar power leaders. But it’s actually working on a solar power project worthy of global notice, I think. The solar project will put solar power on “45 secondary schools, 10 health centres, 120 dispensaries, municipal buildings and businesses across 25 village market centres currently without access to the electricity grid.”

Solar-powered electricity prices could soon approach those of power from coal or natural gas thanks to collaborative research with solar start-up Ampulse Corporation at the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL).

In an attempt to become environment-friendly, the Indian Railways plans to set up renewable energy generation capacities—such as wind power, solar energy and bio-diesel plants—for its own use, railway minister Dinesh Trivedi said in his budget speech on Wednesday.

"Our commitment to provide solar power to Haiti will empower local schools and other community facilities, and give students a great place to study and learn while reducing dependency on expensive diesel power and polluting fossil fuels," said Petersen. "I look forward to partnering with the Clinton Foundation as we grow and identify new opportunities to harness the power of the sun by expanding the use of solar power in Haiti."

San Jose-based SunPower (SPWRA) has landed a plum contract: Its solar panels will generate electricity for Apple's (AAPL) massive new data center in Maiden, N.C., according to a filing with regulators in that state.

Borrego Solar Systems, Inc., has announced the completion of a 3.4 MW solar power installation at Edwards Air Force Base in Southern California.

Lang Son's total power savings hit 4.2 million kWh in the first 10 months of 2011.

A three-phase, $30 million, multi-agency project known as SPIDERS, or the Smart Power Infrastructure Demonstration for Energy Reliability and Security, is focused on lessening those risks by building smarter, more secure and robust microgrids that incorporate renewable energy sources.

Vietnam saved about 1.31 billion kWh in 2011 accounting for 1.42 percent of the amount of commercial power and exceeding what was planned for the year, said Electricity of Vietnam (EVN).

A groundbreaking ceremony for the Song Lo 3 hydroelectric power plant was held in the northern province of Ha Giang on December 21.
