Solar power has always seemed on its surface to be the perfect solution to the world’s reliance on fossil fuels. After all, sunlight is free and abundantly available. The problem has always been efficiency, since solar panels generate power far less efficiently than other options. In fact, it takes about 40 square meters of solar panels to generate enough energy to power just one American home for a day, based on average use.
Progress is slowly being made in labs around the world, though you might not know it by looking at the recent performance of solar stocks. But now, a breakthrough in the way solar energy is collected could double the amount of power generated by solar panels without dramatically increasing cost. More →
