The investment firm Lazard has a nice report[1] on comparing U.S. energy costs by source. Here's the costs in the U.S. (without counting subsidies): * Wind: $ 32/MWh * Solar: $ 43/MWh * Natural Gas: $ 52/MWh * Coal: $ 65/MWh * Geothermal: $ 82/MWh * Biomass: $ 82/MWh * Nuclear: $ 97/MWh * Solar+Storage: $ 119/MWh * Diesel: $ 212/MWh So wind and solar are currently the cheapest, but you can only get to about 50% penetration with those without storage[2]. The rest has to be "dispatchable". [1]: https://www.lazard.com/media/2390/lazards-levelized-cost-of-energy-analysis-90.pdf https://www.lazard.com/media/2390/lazards-levelized-cost-of-...
