Google đang giúp Mỹ xây dựng cáp điện dưới biển quy mô lớn, chạy dọc bờ Đông, nhằm chuyên chở điện sạch từ các cánh đồng gió tới những khu vực đông dân cư nhất nước này. Bắt đầu từ Nam Virginia và kết thúc tại Bắc New Jersey, hệ thống cáp sẽ nằm dưới đáy biển, vào khoảng từ 10 đến 20 dặm ngoài khơi. Nó có thể chuyển tải được 6 nghìn megawatt điện sạch, đủ nguồn điện cung cấp cho gần 2 triệu hộ gia đình.

Finland is one of the leading countries in the world in the field of clean technologies, especially industrial sewage treating technology and renewable energy development technology. Not only that, the country is also well known for its sustainable development of urban and rural areas as well as its comprehensive solutions to conserve and assess the environment’s condition, control air pollution and protect water sources.

Theo tạp chí Applied Physics Letters, các nhà khoa học New Zealand đang nghiên cứu chế tạo một loại máy phát điện "mềm" làm bằng cơ nhân tạo, dùng tụ điện biến thiên giúp chuyển hóa cơ năng thành điện năng.

Citing the nuclear disaster in Fukushima, environmental activists at a U.N. meeting Sunday urged bolder steps to tap renewable energy so the world doesn’t have to choose between the dangers of nuclear power and the ravages of climate change.

Richard MacLellan, Halifax Regional Municipality’s SEMO Manager (Sustainable Environment Management Office) remarked that adopting solar heating technology was a good cost- effective proposition. As the demand for hot water was very high in the building, the opportunity for savings by decreasing the operating costs in the facility was also huge. He mentioned that they would continue their exploration to discover the most promising and innovative renewable technology that could be used in the projects.

Senator Joe Lieberman called for a temporary halt on the building of nuclear plants in the U.S., and many news organizations have reported that it could cause a major setback for U.S. nuclear policy. Last year, the Department of Energy announced $8.3 billion in loan guarantees for the construction of two nuclear plants in Georgia. The plants are part of a major push by President Obama and Energy Secretary Steven Chu to support nuclear power in the United States.

IDTechEx recently visited GS Caltex in Seoul, Korea, who have developed a solid state lithium thin film battery. The company is a joint venture between GS, Korea and Chevron, USA, and its core business is oil refinery where they are number two in Korea. The company also works on renewable energy including fuel cells, biofuels, materials for supercapacitors and thin film batteries.

The first new nuclear reactor ordered in the U.S. in roughly three decades is beginning to take shape near Augusta, Ga. Southern Company and its partners have dug 27.5 meters down to reach bedrock and are now refilling the hole to provide a stable, anchored foundation for what is likely to be the first of a new generation of reactors in the U.S.: two new AP1000 models at the Vogtle Electric Generating Plant that stand next to two older pressurized water reactors, which came online in the 1980s—the first of some 14 AP1000s and 20 new reactors in total that may be built in the U.S. in the next 15 years.

In doing so, it will launch the Agency for the Cooperation of Energy Regulators (ACER), to take decisions on cross border energy supply. ACER will draft framework guidelines for the operation of cross border electricity networks, establishing rules that are consistent with these guidelines, the Commission said. Its role will be to monitor the newly managed internal European electricity market, including retail prices, available network access for electricity produced from renewable sources.

Solar Junction is a 4-year-old company spun out of Stanford University that designs high-efficiency, multi-junction solar cells for concentrating photovoltaic (CPV) solar collectors. The National Renewable Energy Laboratory recently certified that its solar cells can operate at 40.9% efficiency, a significantly higher efficiency than typical silicon solar cells that convert sunlight to electricity at an efficiency of about 15-20%.

Scientists are reporting development of an advanced lithium-ion battery that is ideal for powering the electric vehicles now making their way into dealer showrooms. The new battery can store large amounts of energy in a small space and has a high rate capacity, meaning it can provide current even in extreme temperatures.

Wind turbine prices last year fell below 1 million euros ($1.4 million) a megawatt for the first time since 2005, Bloomberg New Energy Finance said. Global turbine contracts signed in the last six months of 2010 for delivery this year averaged 980,000 euros a megawatt, the London-based analyst said today in a statement. That’s down from 1.06 million euros for contracts signed in 2009 and a peak of 1.21 million euros in 2007 and 2008, the group said.

Theo Công ty tư vấn và phân tích tài chính quốc tế Bloomberg New Energy Finance, năm ngoái - lần đầu tiên kể từ năm 2005 - giá của tuabin gió giảm xuống còn dưới 1 triệu euro/megawatt (khoảng 1.4 triệu đôla Mỹ). Theo chuyên gia phân tích tại London ngày 7 tháng 2 cho biết, các hợp đồng vận chuyển tuabin trên thế giới trong 6 tháng cuối năm 2010 ở mức trung bình 980 euro/megawatt. Con số này đạt mức cao nhất đạt đỉnh là 1.21 triệu euro năm 2007 và 2008, và năm 2009 là 1.06 triệu euro.

Advocates of coal power argue that it is among the cheapest sources of energy in the United States and allows for lower-cost power. But a new Harvard study found that whatever money is saved in operation costs is completely negated by the cost coal plants inadvertently pass on to the American public: $345 billion.

Gaining new insight into how efficiently the microbes in large bioreactors produce methane from brewery waste, Cornell scientists hope to use their new knowledge to shape these microbial communities to produce liquid biofuels and other useful products.

The demand for renewable energy is expected to triple over the next decades according to U.N.E.P.’s Year Book 2011. United Nations Environment Program’s 2011 Year Book predicts this year to be the first where low-carbon energy capacity exceeds that of fossil-fuel.

The global market for LED light fixtures, which already stood at $3.8bn in 2010, is expected to grow to $8.3bn within the next three years, according to new research. The heightened awareness of energy efficiency together and global fiscal stimulus has created suitable conditions for the adoption of white light application of LED technology, which would otherwise have faced high costs.

Automobiles, military vehicles, even large-scale power generating facilities may someday operate far more efficiently thanks to a new alloy developed at the U.S. Department of Energy's Ames Laboratory. A team of researchers at the Lab that is jointly funded by the DOE Office of Basic Energy Sciences, Division of Materials Sciences and Engineering and the Defense Advanced Research Projects Agency, achieved a 25 percent improvement in the ability of a key material to convert heat into electrical energy.

India was taking serious steps to promote alternative technologies that used bio-fuels and solar and wind energy, a senior official said Saturday. India also has plans to produce more bio-fuels and electric vehicles to save petrol for other vital needs, Sohail Akhtar, director in the ministry of new and renewable energy, said.

The UK government has formally announced that it intends to set up a new independent statutory body to regulate nuclear power in the UK, taking over regulatory functions currently performed under the auspices of two different bodies.
