Fast growing Q-Cells AG became the world's largest solar cell maker in 2007, producing nearly 400 megawatts (MW) worth of product. Longtime solar industry leader Sharp found itself in second place as production slipped to roughly 370 MW, which the company blamed on a constrained supply of silicon. China's Suntech was close behind the leaders with more than 300 MW output, pushing Kyocera and its 200 MW to a distant third.

The biggest challenge for the wind-power industry in India is to come to terms with the need to generate more power and to accurately account for it.
mnre collates data on the installed wind energy capacity, but most experts believe its data on wind power generation is questionable. The Central Electricity Authority does not collect data on wind power generation either. From the data mnre provides, adding capacity has not converted to actual power generation.
The average plant load factor, getting better, is still around 15 per cent. As a result, even as wind power generation has increased from 1,577 million units (mu) in 2000-2001 to 11,413 mu in 2007-2008, it accounts for a meagre 1.6 per cent of all power generated.
Moreover, industry is worried about stagnation in installation. Write Mahesh Vipradas and Niraj Kumar of the Indian Wind Energy Association, in their recent assessment of the sector: “The annual installation in 2007-08 is the lowest in the last three years, making us ask: is this the beginning of the end of the Indian wind success story?” They believe policy measures enacted in the past have had their run of success. Now, more steps are needed to re-energise the sector.

The burden of combating global warming is not restricted to developed countries and many developing countries have shown their commitment to moving towards a more sustainable, low-carbon economy.
A good example of this type of commitment comes from India's West Bengal region, where the country's first housing complex using roof-integrated photovoltaics has recently been completed.
The policy behind the Rabi Rashmi Abasan project, which in the local Bengali language means ‘solar ray-based dwelling', was the brainchild of S. P. Gon Choudhary, managing director of the West Bengal Green Energy Development Corporation Limited (WBGEDCL), a state government-backed renewable energy undertaking.

As part of the photosynthesis process algae produce oil and can generate 15 times more oil per acre than other plants used for biofuels, such as corn and switchgrass. Algae can grow in salt water, freshwater or even contaminated water, at sea or in ponds, and on land not suitable for food production.

Happily, it seems likely to do so soon. Silicon producers, whose biggest customers were always chipmakers, have been slow to cater to the solar industry. They were scarred by the memory of the technology bust of 2001, which had weighed them down with excess capacity, and so delayed expansion—despite the boom in solar. Moreover, it takes three years or so to get a new plant going, so new silicon supplies are only just beginning to materialise.
