Why haven't solar power replaced the use of fossil fuels?

Answer 1

Solar power has not replaced the use of fossil fuels for several reasons. First, solar power goes off at night. A way would need to be found to store it. Second, the sun goes behind clouds and it rains. When the sun does not rain, power is still necessary. More power is needed in the winter when less sunshine is available. It would be possible to produce a lot of solar power in the desert south west, however, high tension direct current lines would be needed to bring the power east. Politics have prevented the building of those power lines.

Answer 2

Solar power has made significant progress, but there are still barriers to widespread adoption. These include high initial costs, intermittency of sunlight, limited energy storage capabilities, and the need for infrastructure upgrades. Fossil fuels remain economically competitive due to established infrastructure and government subsidies.
