It is estimated that by 2030, consumption will have grown by 45%. As a result of rising energy costs and the negative effects of traditional power production, demand for solar energy continues to increase. In the last three years, there has been an exponential growth curve taking place in the solar market. The Edison Electric Institute reports that, while 2010 produced approximately 1000 megawatts of solar power, 2011 is estimated to overtake that number by almost double the megawatts. And by 2015, energy produced from photovoltaic sources are estimated to be as high as 7000 megawatts! Think about that for a minute. Let it sink in. Last year, solar produced 1000mW. And within five years, that number will be 700% higher! Furthermore, in 2010, there were 9,000,000 square feet of solar modules installed on metal roofs. But according to the US Department of Energy's Solar America Initiative, by 2015 there will be an additional 80,000,000 square feet of solar electric installations on the grid.
