At best, this is only true when the sun is shining and the wind is blowing. At all other times, their cost is significantly higher. Modern societies need around-the-clock power. The intermittency of solar and wind energy means backup is required, often delivered by fossil fuels.
Wind power LCOE decreased from $135 per megawatt-hour to $43 [$112/MWh to $36/MWh] between 2009 and 2018. Solar LCOE matched this reduction, dropping from $359 to $43 per megawatt-hour [$298 to $36/MWh]. What Makes Wind Energy More Efficient Than Solar Power? Wind turbines transform 60% to 90% of wind energy into electricity.
Similarly, a peer-reviewed study of Germany and Texas shows that the real costs of solar and wind are many times more expensive than fossil fuels. Germany, the U.K., Spain, and Denmark, all of which increasingly rely on solar and wind power, have some of the world's most expensive electricity. Source: IEA.org energy prices data set
Global evidence is clear: Adding more solar and wind to the energy supply pushes up the price of electricity for consumers and businesses. Families in Ontario know this already from their bitter experience: from 2005, the Ontario government began phasing out coal energy and dived headlong into subsidizing wind and solar generation.
Media outlets have repeatedly made similar claims over the past decade, but as with those previous stories, data on power prices and trends in those states show the claim to be false.
The United Nations, in two new reports, indicates that the global switch to renewable energy has passed a “positive tipping point” where solar and wind power will become even cheaper
The cost of renewable energy has reached a historic tipping point in 2025, with solar and wind power now representing the cheapest sources of electricity generation in most regions
Uncover more realistic prices of solar and wind energy and understand the implications for the future of renewable electricity generation.
The actual costs of solar and wind energy are far higher than green campaigners claim.
Residential wind turbines are typically more expensive and have higher maintenance costs. Energy Production: While wind turbines can convert up to 60% of wind energy into electricity
Wind and Solar Energy Are Cheaper Than Electricity from Fossil-Fuel Plants Even without subsidies, renewable energy is staying competitive with power from gas and coal
In 2024, solar photovoltaics (PV) were, on average, 41% cheaper than the lowest-cost fossil fuel alternatives, while onshore wind projects were 53% cheaper. Onshore wind remained the
The cost assessments also fail to account for how wind and solar projects cannot be built just anywhere and often require new, long, expensive, and inefficient transformation lines to deliver
