Your question is weird. Solar does compete economically with methane already, and it's only going to improve even more.
If true, why aren't we mass scaling it all over the American West? We have railways running from West -> East, why not include power lines that can take power from energy farms in the West -> East? No major project in AZ, TX, or CA to give a city free power? etc
67% of new grid capacity in the US was solar in 2024 (a further 18% was batteries, 9% wind, and 6% for everything else). In the first half of 2025 that dropped to 56% solar, 26% batteries, 10% wind, and 8% everything else (gas). Source for numbers: https://seia.org/research-resources/solar-market-insight-rep...
