"Ten years ago, American companies owned 50 percent of the market for solar photovoltaic panels -- the key technology necessary for solar power. Today, says Thomas Werner, CEO of SunPower, a solar-technology company based in Silicon Valley, the United States has just a 10 percent share.
Yet even as the U.S. has lost its lead in solar, the worldwide demand for it, and other renewable power sources, such as wind, has surged. According to one report, solar and wind power generation capacity has grown by more than 30 percent annually over the past five years. That's the kind of growth market high tech venture capitalists and entrepreneurs are normally desperate for.
But while demand is growing, and countries such as Japan and Germany are pushing renewable energy technology development to the limit, the U.S. is lagging. For some energy experts, the failure is more than just a missed opportunity for profits -- it's a profound strategic and environmental screw up. And the responsibility for it belongs right at the very top -- the energy policy formulated and executed by the current presidential administration. The high price of oil, the threat of global warming, the mandate to develop markets that will spur domestic job growth: all these factors call out for leadership that would push the development of new sources of energy, that would encourage the growth of markets that could literally save the world."
