The sun power industry in Germany, the world's leader in solar energy, is facing a tough year amid the threat of growing competition from Asia and falling prices. German solar-power companies rebounded last year from a dramatic slump in profit during 2009 as a boom in the sector took shape last year.

The Indian government recently provided subsidies worth $10 million for projects aimed at promoting the use of solar energy in rural areas. The subsidies went to projects which distributed solar lanterns and installed solar home-lighting systems in villages across the country.

The Asian Development Bank (ADB) said a fund it established to develop large capacity solar projects will increase the renewable energy resource to 3GW by mid-2013 in the Asia and Pacific region. Haruhiko Kuroda, president of ADB, said governments in Asia and the Pacific should invest in solar energy to help ensure their growth is environmentally sustainable.

A plan to install solar energy panels on two Reigate council buildings is set to save money and reduce carbon emissions, a councillor has said. Councillor Julian Ellacott said the solar panels could generate electricity worth hundreds of thousands of pounds over their 25-year lifespan.

The heat radiating off roadways has long been a factor in explaining why city temperatures are often considerably warmer than nearby suburban or rural areas. Now a team of engineering researchers from the University of Rhode Island is examining methods of harvesting that solar energy to melt ice, power streetlights, illuminate signs, heat buildings and potentially use it for many other purposes.

The initial line-up of energy efficient roofing products, includes a solar energy-generating system, a unique ventilation and insulation product, along with steel and aluminum shingles. According to company President Todd Miller, "We are bringing products to market that allow homeowners to invest in and improve their current homes, and do so in a way that benefits the environment."

Dr. Nguyen The Hung from the Institute of Physics under the Vietnam Academy of Science and Technology has contributed to the efforts to realize the above objective by creating a type of power generator using natural light. In 2008, Dr. Nguyen The Hung and his colleagues began a research project aiming to manufacture a type of power generator system using solar energy according to the absorption diffusion principle (with natural light engine).

The Asian Development Bank (ADB) is optimistic that Asia can get the 10 trillion US dollars it needs to finance sustainable energy projects over the next 20 years. The projects will include more efficient use of coal and oil as well as greater reliance on renewable power sources such as wind and solar energy.

MIT researchers are hopeful of capturing and releasing solar energy with the help of thermo-chemical technology. Scientists were already working on this technology in seventies but this project was aborted due to its expensiveness and termed as too impractical to achieve. But MIT researchers are now gearing up to take this thermo-chemical technology that is supposed to convert solar energy into electrical energy.

A few days ago, the Israel-based energy company ZenithSolar has officially unveiled its 3rd generation Solar Z20. Being installed in Kibbutz Yavne in central Israel, the solar energy generator is a combined heat and power system, able to deliver 72% efficiency.

Leave it to larger-than-life Texas to lead the U.S. into a new energy future. While the state is most closely associated with oil, it has also been an early pioneer of wind power, and is beginning to embrace solar energy along with armloads of new green jobs. Now the San Antonio Water System has set the national bar high in the sewage-to-biogas field, by becoming the first water district to hook a biogas facility up to a commercial gas pipeline.

A new report out by the Solar Energy Industry Association (SEIA) and GTM Research, the inaugural U.S. Solar Market Insight™ report, finds that solar power is going to continue its rapid growth in the United States.

The U.S. Department of the Interior (DOI) approved on October 5 the first large-scale solar energy plants ever to be built on U.S. public lands. The approval of two developments in California grants the U.S.-based companies behind the projects access to almost 6,800 acres of public lands for 30 years to build and operate solar plants. The approved plants could produce up to 754 megawatts (MW) of renewable energy, or enough to power 226,000–566,000 typical U.S. homes. The projects will generate almost 1,000 new jobs.

Advances in solar energy efficiencies have so far been made with irregular surfaces, thinner tabbing between cells, more optically perfect glass and even special coatings, but now Stanford engineers say the best efficiency is via ultra-thinpolymer films inside solar cells that allow more “bounce room.”

The new nano-ceramics would be key components in the next generation of capacitors. Like batteries, capacitors store energy, but there the resemblance ends. Batteries are designed to collect energy over a relatively long period of time, then release it at a low, constant rate. Capacitors charge and release large amounts of power very quickly. The basic principle has been around since the 18th century, but until recently one roadblock has been how to reduce them down to an efficient size.

Along with urban growth, the demand for use of energy in urban areas has increased rapidly, especially in big cities such as Hanoi, Hai Phong, Ho Chi Minh City, Da Nang and Nha Trang. In such circumstances, using solar energy is considered to be a solution that will help reduce energy consumption in urban areas and prevent climate change. This solution was discussed at a workshop themed 'Climate change and sustainable urban development in Vietnam' that was held recently in Hanoi.

A report published by an Indian Defense ministry-backed think tank has proposed for the establishment of an international space-based solar energy program with India and the United States initiating this massive project. The report is prepared by Peter Garretson, a US Air Force lieutenant colonel, working with the Institue of Defense Studies and Analyses, New Delhi. The reports calls for the Indian and the United States’ governments to extend their strategic partnerships to initiate this pathbreaking project and make the space-based solar energy a commercially viable business venture by 2025.

A new study reported in the journal Applied Physics Letters in August this year (published by the American Institute of Physics), explains how solar energy could potentially be collected by using oxide materials that have the element selenium. A team at the Lawrence Berkeley National Laboratory in Berkeley, California, embedded selenium in zinc oxide, a relatively affordable material that could make more efficient use of the sun’s power.

The Swiss manufacturer Trunz Water Systems and a California-based reverse osmosis company, Spectra Watermakers have developed a new eco-friendly water purifier designed for use in disaster stricken areas where conventional energy sources are unavailable or too expensive. The new system, called the Solar Container, is capable of generating more than 8,000 gallons of potable water per day and is powered by renewable wind and solar energy.

The University of Cambridge has come up with a low cost organic solar cell that opens up some intriguing new possibilities in solar energy design. Although the Cambridge team is focused on bringing large scale photovoltaic devices to the market, the new technology could also lend itself to a smaller canvas, yielding such products as solar-energy generating umbrellas and canopies. For that matter, even small objects like plastic cups and straws could some day double as mini solar power generators.
