No.
Unsubsidized utility-scale solar is now generally cheaper than building fossil fuel power plants.
Costs are often compared using “levelized cost of energy,” the average lifetime cost to build and run a power plant divided by the electricity it produces. A 2025 analysis estimates the mean LCOE of utility-scale solar at about $58 per megawatt-hour without subsidies, compared to $79 for new natural gas plants and $128 for new coal. The International Energy Agency reports solar energy is the cheapest source of new electricity generation in most parts of the world.
Solar costs have fallen sharply over the past decade as panel prices have dropped and the industry has grown. Subsidies can further lower costs, but solar is not dependent on them to compete with fossil fuels.
