The report gives an overview of the market forces that are currently driving the global demand for solar power and discusses the probability and consequences of the possible oversupply situation. The first part of the report looks at demand dynamics in the world’s major PV markets. Government policies will come into play as Germany, Spain and the U.S. face uncertainties regarding their respective subsidy programs.Read on...

Considering that the energy in sunlight reaching the earth in just 70 minutes is equivalent to annual global energy consumption, the potential for solar power is virtually unlimited. With concentrating solar thermal power (CSP) capacity expected to double every 16 months over the next five years, worldwide installed CSP capacity will reach 6,400 megawatts in 2012—14 times the current capacity. (See data.)
Unlike solar photovoltaics (PVs), which use semiconductors to convert sunlight directly into electricity, CSP plants generate electricity using heat. Much like a magnifying glass, reflectors focus sunlight onto a fluid-filled vessel. The heat absorbed by the fluid is used to generate steam that drives a turbine to produce electricity. Power generation after sunset is possible by storing excess heat in large, insulated tanks filled with molten salt. Since CSP plants require high levels of direct solar radiation to operate efficiently, deserts make ideal locations.

Cleantech is reporting that though the exact financial terms of the deal have not been disclosed, Hindustan Petroleum will hold 74% of the joint venture and will received the entire harvest of jatropha seeds, which it will then refine into biodiesel for sale at its retail outlets across the state of Chhattisgarh. The land used for cultivation will be wastelands obtained by CREDA.
India has conducted a number of trials using Jatropha-based biodiesel on it public transport systems, both on major train routes and on public buses.Read on...
In Western China, the Renewable Energy Development Project (REDP), has brought affordable, high-quality solar lighting to people who live in tents in rural areas. Since 2001, REDP has sold over 402,000 photovoltaic (PV) solar-home systems to yak and other herding communities in remote areas. Previously they relied on kerosene, butter lamps and candles for light. Now almost 1.44 million people who previously had little access to electricity have an improved quality of life through better light, communications and entertainment.Read on...
