According to a 2011 projection by the International Energy Agency, solar power generators may produce most of the world’s electricity within 50 years, dramatically reducing the emissions of greenhouse gases that harm the environment. Cedric Philibert, senior analyst in the renewable energy division at the IEA said: “Photovoltaic and solar-thermal plants may meet most of the world’s demand for electricity by 2060 -- and half of all energy needs -- with wind, hydropower and biomass plants supplying much of the remaining generation”. “Photovoltaic and concentrated solar power together can become the major source of electricity,” Philibert said. Economic trends All forms of energy are expensive, but as time progresses, renewable energy generally gets cheaper, while fossil fuels generally get more expensive. A 2011 IEA report said: ...

MANILA – Asian Development Bank president Haruhiko Kuroda opened Tuesday (June 5) a new rooftop solar power project that will provide clean, renewable energy to ADB’s 20-year-old headquarters in Manila. “Using rooftops and other open spaces is an efficient way for businesses and homes to capture and use the energy of the sun,” said S. Chander, Director General of ADB’s Regional and Sustainable Development Department. “We hope other companies will follow ADB’s example.” The 2,040 photovoltaic panels occupying 6,640 square meters on the roof of ADB’s main building will generate 613 megawatt hours of electricity per year to run a portion of the Bank’s air conditioning, lighting, and computer systems, reducing its carbon footprint. The solar rooftop project received support from Philippine government agencies, such as the Department of Energy, the City Government of Mandaluyong, the Manila Electric Company, the Civil Aviation Authority and the Department of Environment and Natural ...
