Whether it was planting millions of trees, turning food waste into electricity or using smart grid technology to slash its energy use, British supermarket Sainsbury's has been slowly but surely beefing up its sustainability credentials.

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.

More than 14 energy conservation and 40 industrial promotion centers have been established in the whole country in order to promote saving and using energy efficiently by direct consulting for business. However, until now, half of them have only played propagandizing roles.

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.

The Victorian Labor Party has sought to underline its renewable energy credentials by vowing to help the town of Newstead, near Bendigo, to become 100 per cent renewable energy by 2017, and become the state’s first “solar town”.

With the number of Internet connected devices rapidly increasing, researchers from Melbourne are starting a new research program to reduce energy consumption of such devices.

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.

According to the EPA, using recycled aluminum only uses 5% of the energy and emissions that are needed to extract new aluminum.

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

This initiative, according to Benon Mutambi the Electricity Regulatory Authority (ERA) Chief Executive Officer will cost the government about $4.1m. The initial batch will be distributed to consumers starting January 2015.

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.

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.

Solid-state lighting technologies, which include both LED and organic light emitting diode technologies, have the potential to save Americans $26 billion a year in energy costs by 2030.

Tổng công ty Cổ phần Dệt may Hà Nội (Hanosimex) đã đầu tư gần 223,5 triệu đồng lắp đặt thiết bị tiết kiệm điện cho máy may 3S (Systech sewsaver) giảm công suất động cơ lúc hoạt động không tải để tiết kiệm điện.

The sea has long been a source of Norway's riches, whether from cod, farmed salmon or oil. Now one researcher from the Norwegian University of Science and Technology (NTNU) researcher hopes to add seaweed to this list as he refines a way to produce "biocrude" from common kelp.

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.

Indian wind energy companies are looking to invest in offshore wind energy projects as the government plans to significantly increase the annual capacity added in the wind energy sector as a whole.

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.

Texas Tech University researchers will receive $1.4 million from the U.S. Department of Energy to develop a new radar prototype that will provide better measurements of the complex flow conditions in wind plants.
