The hidden cost of ultra-cheap solar power
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.
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.
Solar photovoltaics (PV) is a very modular technology that can be manufactured in large plants, which creates economies of scale, but can also be deployed in very small quantities at a time. This allows for a wide range of applications, from small residential roof-top systems up to utility-scale power generation installations.
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.
“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.
