Rooftop solar electricity on pace to beat coal, oil
Found on Computerworld on Wednesday, 19 November 2014
The sharp decline in solar energy costs is the result of increased economies of scale leading to cheaper photovoltaic panels, new leasing models and declining installation costs.
The cost of solar panels, or solar hardware, used to represent two-thirds of the overall price to install solar power. Over the past five years, however, that has flipped to where "soft costs," which include labor, permitting and advertising, now represent the majority of the cost.
Decentralized solar electricity is by far better than wind energy. Plenty of roofs are available and the panels won't cause as many problems as wind wheels.
