Both wind power and solar have passed the levelized cost of energy (LCOE) barrier which make them cheaper than almost every other form of electricity generation – at scale. The ubiquitous Combined Cycle Gas Turbine is perhaps still on a par in pricing terms per MWh in some territories, but every year renewables fall in price, while CCGT is tied to the cost of obtaining gas. It also throws off a lot more CO2 than renewables, so…
