Solar & Wind Power Overtake Coal as World’s Largest Source of Electricity
For the first time ever, the world has generated more electricity from solar and wind power than from coal.
According to a recent report by energy think tank Ember, the growth of renewable energy has officially overtaken coal as the largest generator of electricity worldwide. This is a huge milestone that reflects not only a symbolic shift, but a practical demonstration of how renewables can keep up with the world’s soaring appetite for electricity.
The Numbers Behind Renewables Growth
Due to various factors such as economic growth, electrical vehicle use, data centres, and increased cooling needs in hotter climates – global electricity demand is rising.
Despite this growing demand, renewables were able to supply 100% of the increase in global electricity usage in the last year. That means technology like solar and wind power is advancing rapidly, and despite what many think, it can keep up with the population’s demands.
In the first half of the year, solar power generation grew by 31%, which is the fastest growth on record. Wind power grew by 7.7% in the same period, contributing to a combined growth of over 400 terawatt hours of electricity. That easily covers more than the total global demand increase.
And it now means that renewables account for 34.3% of worldwide electricity generation, passing coal which sits at 33.1%.
While China and India drove much of this growth, Europe and the US still leaned more heavily on coal and gas. Nevertheless, the overall global trend is clear: renewables are no longer the “alternative” – they are becoming the backbone of energy generation.

Why This Matters
This isn’t just about numbers. It’s about what they represent:
- A proof of concept – Renewables can not only supplement but outpace fossil fuels, even as demand continues to climb.
- A cleaner future – Every percentage point gained by renewables means less reliance on carbon-intensive coal and gas, reducing greenhouse gas emissions.
- Momentum for change – Predictions suggest that renewable energy generation could double by the end of the decade, accelerating the transition to a low-carbon world.
The Local Perspective
At Sunbright Energy, we see this global shift reflected in the choices of homeowners here in the South East of the UK. More people are recognising that solar is not just an environmentally responsible choice – it’s also a practical way to reduce energy bills, gain independence from rising grid costs, and future-proof your home.
One of our most recent solar installations in Kent is a clear example of that, where their solar system is generating over 94% of their annual energy demands, and saving them just under £100,000 over 25 years. Read more about that specific solar installation in Rochester, Kent right here.
The fact that solar and wind are now generating more power than coal worldwide highlights a simple truth:
Renewables aren’t just the future of energy. They’re the present, and they’re taking over right now!

How You Can Join the Shift
The world is catching on to the potential of solar power – but changing power supply isn’t just in the hands of governments or big corporations. You make the switch in your own home too.
By installing solar panels at your home, you can:
- Generate your own clean electricity
- Cut your reliance on expensive fossil-fuel-generated power
- Protect yourself from energy price hikes
- Play your part in a cleaner, more sustainable future
As a local solar installer based in the South East, Sunbright Energy can help you take the next step. We design and install high-quality solar systems tailored to your home, so you can start benefiting right away.

Final Thoughts
Switching the world’s predominant electricity supply from coal to renewables is a global milestone. It’s proof that solar and wind aren’t just alternatives anymore – they’re leading the way.
If you’re still not powering your home with renewables in 2025, not only is your energy going to become more expensive over time, but you’re getting left behind the millions around the world who are accessing cheaper bills, energy independence, and leaving the world in a better, greener place.

FAQs
How much of the world’s electricity comes from renewables?
As of 2025, renewables account for 34.3% of worldwide electricity generation, passing coal which sits at 33.1%. This makes renewable energy the largest source of electricity across the globe.
What are the benefits of renewable energy?
Renewable energy, like solar and wind, is an infinite source of energy that isn’t only available in a finite amount, such as coal. It doesn’t produce greenhouse gas emissions to generate, meaning it lowers CO2 output and protects the environment. Renewables are also cheaper for consumers as once solar panels are installed or wind turbines built, there aren’t many associate costs to generate electricity.
What are the benefits of solar panels?
Solar panels help consumers lower their energy bills by 70% or more, by reducing their reliance on expensive grid energy. They also reduce CO2 output, with the average UK domestic system saving over 1,000kg of CO2 per year.
