Types of renewable energy
What is a renewable energy source?
A renewable energy source means energy that is sustainable – something that can’t run out, or is endless, like the sun. When you hear the term ‘alternative energy’ it’s usually referring to renewable energy sources too. It means sources of energy that are alternative to the most commonly used non-sustainable sources – like coal.
What is zero-carbon or low-carbon energy?
Nuclear-generated electricity isn’t renewable but it’s zero-carbon(1), which means its generation emits low levels or almost no CO2, just like renewable energy sources. Nuclear energy has a stable source, which means it’s not dependent on the weather and will play a big part in getting Britain to net zero status.
All our tariffs are backed by zero-carbon electricity(1) and if you choose to switch to us, you could play your part now in achieving the net zero target.
The most popular renewable energy sources currently are:
- Solar energy
- Wind energy
