Through the centuries, scientists have found innovative ways to harness the power of the sun — from magnifying glasses to steam engines. Converting more solar power into electricity is high on the political agenda in many countries, amid the push to find domestic energy sources that are less polluting than fossil fuels.
Solar is growing quickly in the United States. According to the Solar Energy Industries Association, more solar was installed in the third quarter of 2011 than in all of 2009 combined.
Assisted by technological innovation and years of government subsidies, the cost of solar power — and wind power — has fallen sharply, so much so that the two industries say that they can sometimes deliver cleaner electricity at prices competitive with power made from fossil fuels.
At the same time, solar and wind power companies are telling Congress that they cannot be truly competitive and keep creating jobs without a few more years of government support.
Solar and wind companies argue that the tax breaks they are seeking are different. The tax credits can be taken only by businesses that are already up and running, so taxpayers are less likely to be stuck subsidizing a failing company, proponents say.
Without the new breaks, industry executives warn, they will be forced to scale back production and eliminate jobs in a still-weak economy.
President Obama, who has been a steadfast supporter of clean-energy programs, has already begun making a case for new government investment in clean energy projects as a way to foster both energy independence and employment at a time when Capitol Hill evaluates new laws in terms of job creation as well as budget cost or savings.

Fairly good summation on solar energy. What many people still don’t know is that solar power is very affordable now. It’s much cheaper than conventional energy over the long term.
