For as of this year, solar has become cost - competitive with many energy sources — often beating natural gas on combined levelized costs and even edging out coal in a growing number of markets.
NATURAL GAS, compared to coal, is better in terms of greenhouse gases and other emissions (especially when burned in new combined cycle electric power plants).
Two basic factors contributed to lower electricity generation carbon intensity (CO2 / kilowatthour) since 2005: substitution of coal - fired generation with the less - carbon - intensive and more efficient combined - cycle natural gas - fired generation, and growth in non-carbon electricity generation, especially wind and solar.
