Not as important as many doomsayers would have you believe. There are real costs to society in the use of "green" energy, and someone will pay the bills -- and go without something as a result. A photovoltaic system presenty costs about $10 per watt of capacity to install, and can generate at most 2 kWh of energy per year per watt of capacity. That much energy is worth about 25 cents, so the return on investment ****s. Subsidies from various sources can reduce the cost to an individual installer, but that merely shifts the burden to somebody else -- such as the taxpayers.
