The aircraft, a heavily modified microlight, uses a conventional four-stroke petrol engine as its main power source and an electric motor connected to a bank of 16 large lithium-polymer batteries built into the wings.

Pursuing energy efficient ways will help reduce electricity consumption and save as much as Rs 50,000 crore, according to Power Minister Piyush Goyal.

Lincoln-Sudbury Regional High School kicked off its SEED program with a powerful all-school presentation by Alliance for Climate Education. The ACE Assembly was a natural lead-in for recruiting students to the SEED program, which promotes greenhouse-gas-reducing efficiency upgrades in their community.

Lithium ion batteries power everything these days from smartphones to electric cars. They’ve been a great advance in portable power storage. On the downside, their spread also makes a big contribution to electronic waste dumps often found in developing countries.

No one, not even the world’s largest coal-mining company, will escape from the impending solar energy revolution in India. The Indian government-owned company has announced its latest initiative to expand solar power infrastructure.

Solar energy in the United States is becoming a major part of the nation's power sector as installation costs decline, Energy Secretary Ernest Moniz said.

Building-integrated solar photovoltaic modules are fast catching up in the rapidly evolving construction business where emphasis on energy efficiency and self-reliance are becoming increasingly popular.

“The introduction of solar as the scheme’s first renewable energy product is a fantastic addition to Warm Up North’s range of energy efficiency solutions that will allow even more households to save energy and money.

Every shower, you’ll save enough electricity to power a 60-watt light bulb for eight hours, or a 20-watt LED for 24 hours. Every year, you’ll save the amount of water it takes to wash more than 70 loads of laundry.

The intelligent streetlight system, designed by Dutch Delft University of Technology, using motion sensing technology that automatically dims streetlights to 20% power when no pedestrians or vehicles are in the vicinity—and the idea is ready to go commercial.

Amazon has been under pressure for a while to get its act together when it comes to renewable energy (just last week we wrote about how shopping on Amazon is powered by coal).

It converts about 200,000 litres of feedstock and 1,200 tonnes of residues per day. The power generation unit produces enough electricity to supply about 8% of the factory’s total power requirement, which, in turn, saves about £100,000 every year.

Researchers have developed a solar cell that is able to directly split water. It does not produce electricity in a first step and split the water in a second step, but rather only has one step.

The device consists of the mesh solar panel, which acts as the first electrode, beneath that is a thin sheet of porous carbon that is the second electrode and a lithium plate that is the third electrode. Between the electrodes are sandwiched layers of electrolyte for carrying electrons back and forth.

Nine out of 10 Australians have considered, or would consider, switching to solar energy as a way to cut their power bills, a new survey has found.

Thanks to NIRD, several inaccessible villages in the State are enjoying solar home lighting system and even the rural economy is looking up with transfer of technology.

A new project helps give kids a safe place to play soccer in a Rio de Janeiro favela by using kinetic-energy harvesting tiles to produce electricity for keeping the lights on.

The Environment Ministry will begin a model project in which surplus electricity generated from renewable energy sources, such as wind and solar power, will be utilized to produce hydrogen for fuel-cell vehicles.

In terms of electricity, 95.3 billion units were saved. India’s annual consumption of electricity is about 700 billion units. If this entire saved electricity had to be produced from coal-based thermal power plants, India would have burnt another 98 million tonnes of coal.

Nếu trung bình hàng năm SunPower sản xuất khoảng 90.000 tế bào năng lượng mặt trời, thì có vẻ như trong tương lai, SunPower sẽ vượt xa sản lượng này. Vì vậy, một tỷ tế bào năng lượng mặt trời tiếp theo có thể được sản xuất chỉ trong một vài năm tới.
