cost of solar vs coal
According to a study by the investment banking firm Lazard, the cost of utility-scale solar energy is as low as 5.6 cents a kilowatt-hour, and wind is as low as 1.4 cents. In comparison, natural gas comes at 6.1 cents a kilowatt-hour on the low end and coal at 6.6 cents. Without subsidies, the firmâs analysis shows, solar costs about 7.2 cents a kilowatt-hour at the low end, with wind at 3.7 cents.
under this measure coal cost less than $ 0 01 per kwh in comparison a barrel of oil at $ 70 barrel produces 1700 kwh at a cost approximately $ 0 05 per kwh let s provide some measures to understand energy costsince coal oil and gas can be measured on a cost per kwh we should measure solar costs on a kwh basis some of the considerations for a solar energy system include the 20 to 30 year lifespan of the system and the hours of available sunlight
