The cost of solar energy has dropped dramatically in recent years and is now competitive with or cheaper than fossil fuels in many parts of the world:
  • Solar energy costs average between 3-6 cents per kilowatt-hour (kWh) and are trending downward[3].
  • Global coal prices have historically averaged 6 cents/kWh. Fossil fuel steam averages around 5 cents/kWh, and small-scale natural gas can be as low as 3 cents/kWh[2].
  • In 2016, a major commercial solar installation bid an extremely low price of 2.9 cents/kWh, effectively leveling the playing field with fossil fuels' cheapest offerings[2].
  • Without subsidies, solar is likely the cheapest energy source in the world, as demonstrated by record low power purchase agreements in countries like the UAE and Chile[2].
  • The upfront costs of solar systems have dropped significantly, with the average cost ranging from $2.40 to $3.60 per watt installed[1].
However, fossil fuels still have the advantage of being a reliable, consistent source of energy. Solar's intermittent nature requires energy storage or baseload power from other sources to maintain grid reliability[1].
Overall, the cost comparison between solar and fossil fuels is complex, with factors like subsidies, environmental impacts, and reliability playing a role. But the rapidly falling costs of solar make it an increasingly attractive and cost-competitive option in many situations.
