Why did renewables become so cheap so fast?
Summary For the world to transition to low-carbon electricity, energy from these sources needs to be cheaper than electricity from fossil fuels. Fossil fuels dominate the global power supply
Solar energy is now so cost-effective that, in the sunniest countries, it costs as little as £0.02 to produce one unit of power, making it cheaper than electricity generated from coal, gas or wind, according to a new study from the University of Surrey.
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 most affordable source of new renewable electricity at USD 0.034/kWh, followed by solar PV at USD 0.043/kWh.
In most places, power from new renewables is now cheaper than new fossil fuels.

“Even here in the UK, a country that sits 50 degrees north of the equator, solar is the cheapest option for large-scale energy generation. Globally, the total amount of solar power installed passed 1.5 terawatts in 2024 – twice as much as in 2020 and enough to power hundreds of millions of homes.

The addition of 582 gigawatts of renewable capacity in 2024 led to significant cost savings, avoiding fossil fuel use valued at about USD 57 billion. Notably, 91% of new renewable

The investment bank''s report measures the levelized cost of energy for various forms of electricity generation. The report is closely watched, and often criticized, in the energy industry,
Lazard''s analysis of levelized cost of electricity across fuel types finds that new-build utility-scale solar, even without subsidy, is less costly than new build natural gas, and competes with
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
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 environmental benefits are just as compelling. Solar panels provide energy with zero emissions, helping cut planet-overheating pollution. Plus, the sun is free to use, meaning
Solar energy is now so cost-effective that, in the sunniest countries, it costs as little as £0.02 to produce one unit of power, making it cheaper than electricity generated from coal, gas or wind.
Generation from solar means emissions equivalent to about 1.6bn tonnes of CO₂ were avoided last year, roughly on a par with US power sector emissions, according to Ember.
