Here comes the sun

Thanks to a continuing drop in the cost of producing it, there is even more incentive to make the switch to renewable solar energy. As solar technology has advanced, the price of solar energy production has dropped. In 1977, it cost $77.67 per watt to produce energy with solar; by 2013 it had dropped to a mere 74 cents per watt. That’s in line with what it costs to use coal or natural gas, and the economic incentive is influencing global solar power installations. According to an industry report by Solarbuzz, by the end of the first quarter of 2015, global demand for new solar energy will exceed 50 gigawatts per year, which would be a jump of more than 100 percent in four years.
