Why did renewables become so cheap so fast?
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.
In 2021, solar PV accounted for nearly half of all new capacity installed globally, with the IEA reporting that solar power is now the cheapest source of electricity in history. According to a recent study, solar energy is expected to become even cheaper in the coming years, with costs projected to fall by as much as 60% by 2030.
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.
Governments have also implemented policies that require utilities to use more renewable energy sources, which has helped to spur demand for solar power. As a result of these factors, solar energy is now the fastest-growing source of new electricity generation worldwide.

Solar power became the most affordable energy source between 2021 and 2025, with costs dropping below coal and natural gas in most regions.

Solar power generation faces significant limitations despite its potential as a renewable energy source. 1. High initial costs, 2. Geographic dependence, 3. Weather variability, 4. Storage
The price of electricity from solar declined by 89% from 2009 to 2019. Why Solar Energy Became the Cheapest Power Source in History?
The Stubborn Roadblocks: Why Solar Isn''t Everywhere Yet Despite solar energy becoming so affordable, it remains far from universally adopted. The reasons for this are complex
Solar PV is the world''s cheapest technology to generate electricity, according to a study from the University of Surrey, in the UK.
This surge will exceed existing government targets by nearly 25%, highlighting solar PV''s critical role in a rapidly changing global energy landscape. Solar PV is now the world''s most cost
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.
