Big news in the world of energy, for the first time in history, renewable energy has overtaken coal as the largest source of electricity generation globally.
According to data from Ember, the global think tank, solar and wind power met 100% of the world’s growing electricity demand in the first half of 2025. That means every bit of new electricity we’ve needed this year has come from clean energy sources, not fossil fuels.
Experts are calling this a crucial turning point in renewable energy, one we’ve been waiting for and at SolarTherm UK, working towards.
Solar Leads the Charge
Of all the renewable sources, solar power is leading the way. In fact, solar alone provided 83% of the world’s new electricity growth this year. That’s an incredible figure, and shows just how far solar has come. Advances in technology and major cost reductions (solar prices have fallen by an incredible 99.9% since 1975!), clean energy has never been more accessible or affordable for homeowners and businesses alike.
Countries across Asia and Africa are seeing solar booms. Kenya already gets more than 80% of its electricity from renewables, while South Africa and Nigeria are rapidly scaling up solar power to meet rising energy demand.
Even China, often criticised for its coal use, is now adding more solar and wind power than the rest of the world combined. Renewable energy isn’t just a target for the future, it’s in the present, right now.
Not Every Region Is Moving at the Same Speed
While developing countries are racing ahead with renewables, some of the more wealthier nations are lagging behind. The US and EU, for instance, saw an increase in fossil fuel use this year due to weaker wind and hydro performance and a growing demand in energy.
The global trend is clear, renewables are winning. Every major forecast shows that solar and wind are now the backbone of new power generation and the clean energy transition is accelerating.
