The promise of solar energy is almost too good to be true. Drawing the world's energy needs from that big ball of energy at the center of the solar system is a no-brainer, once you figure out how to actually do it, and do it efficiently and cost-effectively.
For decades, the promise of solar energy has been hamstrung by its cost and inefficiency. It's cheaper to burn coal and oil, so that's what we do.
But all that may be changing. For real, this time. You've heard this before, but according to Yale Environment 360, the new and excellent online magazine about global environmental issues, Solar's Time has Finally Come.
Some analysts predict the solar energy industry will nearly triple in value in the next five years. Others believe solar power will be cost-competitive with nuclear and coal power within 10 or 20 years, without the help of government subsidies.
Why? Like other high-tech innovations that percolated in elite quarters for years before bursting into the mainstream (think microchips), technological improvements make each new generation of photo voltaic cell far better and cheaper than its predecessor.
