The new "L-CSC" supercomputer at the GSI Helmholtz Centre for Heavy Ion Research is ranked as the world's most energy-efficient supercomputer.

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).

According to Lisa Rathke of the Associated Press, energy-saving program Efficiency Vermont has helped ski resorts all over the state make huge strides, with 2,300 new energy-efficient snowmaking guns replacing older wasteful ones.

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.

First, British household budgets would benefit from a £5bn saving every year. This means an average annual saving of around £335 for British families.

Keep electric storage heaters on all the time. Our research also found that few people with electric storage heaters fully understand how they work (only 38%). This means that households with electric heating could be paying through the nose by not taking advantage of cheaper night rate electricity.

Big Energy Saving Week – a joint campaign between Citizens Advice, Energy Saving Trust, and the Department of Energy and Climate Change (DECC) – reveals 74 per cent of Brits are still worried about their energy bills.

John Colucci, vice president of sales and marketing at Westchester Modular Homes, says the up-charge is minimal. He claims that a modular home may cost 3 to 5 percent more for a house that is 50 to 60 percent more efficient than the typical home.

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.

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.

The United Nations Environment Programme (UNEP) has launched a new initiative to accelerate the transition to more efficient appliances and equipment to reduce global energy demand, mitigate climate change and improve access to energy.

All eyes are on New York City this week, as world leaders come together for the U.N. Climate Summit – an event that aspires to shape the national and global energy future.

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.

GS Yang thuộc Viện công nghệ Georgia đang sử dụng hiệu ứng điện ma sát để sản sinh điện năng bằng cách chà sát hoặc cho tiếp xúc hai vật liệu với nhau.

Rıza Köroğlu, director of Istanbul-based Total Energy Efficiency, told the Anadolu Agency (AA) that if Turkey reached the level of Germany - the world's leading energy efficient nation - the country could save $39 billion (TL 87.15 billion) on its $65 billion annual energy spend.

A desalination technology powered by solar panels could provide enough clean, palatable drinking water to meet the needs of India's water-deficient villages, MIT scientists say.

If SunPower’s average annual solar cell production was about 90,000 solar cells, it appears that SunPower will go well beyond this output. So the next billion solar cells they produce will probably occur in just a handful of years.

The ENGO charging station uses kinetic tiles and solar panels to charge up to 14 smartphones at a time, and provides free WiFi access and an emergency phone.

Across the nation, American businesses, families, and communities are embracing clean, renewable energy that is homegrown, healthy, and can never run out. By finding alternatives to fossil fuels that pollute our air and disrupt our climate, they are showcasing the single most practical way to tackle climate change, starting now.

The European Union said it was looking for consultants to evaluate how consistent bloc-wide renewable energy targets are with national legislative measures.
