Green energy: powered by nature

For decades, the UK has been fuelled by dirty energy. Burning fossil fuels shaped our past, but green energy is our future!

What’s green energy?


Green energy is renewable energy.

It comes from renewable sources like the wind, sun, and sea. The fact they’re renewable means we’ll never run out of them.

The best thing about taking energy from these natural resources is that they’re cleaner and healthier. Plus, they’ll be here for us for generations to come!

Sources of green electricity: how does green energy work?

These are the most common renewable energy sources in the UK.

wind energy

Wind

Britain’s blustery shores are a big advantage. In 2020, almost a quarter of the UK’s electricity came from wind turbines.1

Find out how wind energy works.

solar panels

Solar

Clever solar panels catch the sun’s rays and turn them into electricity. They do this with what’s known as the “photovoltaic effect“.

hydro energy

Hydro

Water mills have been used to generate energy for thousands of years. And they’re just as powerful today!

Read our guide to hydroelectric energy.

Tidal energy

Tidal

Tidal energy works by harnessing the natural awesome power of the sea. This is done with turbines, lagoons, and barrages that are placed on the coastline.

Biomass energy

Biomass energy

Biomass energy comes from burning natural matter like wood or food waste. It’s renewable, but there are some questions about how green it really is. 

Learn more about biomass energy.

Geothermal energy

Geothermal energy

Geothermal energy comes from the heat that’s created deep beneath the surface of the Earth.

Benefits of green energy

  • Renewable electricity is called “renewable” because it won’t run out – the sunshine, wind, and tides will go on forever
  • Green energy is low carbon, meaning it has little or no carbon footprint
  • It’s cleaner, and better for our health, than burning fossil fuels
  • And cutting down on pollution is better for our planet’s health, too!
