The best way to achieve the energy security and affordability our country needs is through a diverse mix of technologies.
No one technology can deliver all the energy we need: some are lower-carbon, some are more flexible, some are cheaper, some avoid intermittency of supply - and all are developing as technology moves on.
Only a varied and increasingly low-carbon energy mix can meet the three challenges of energy security, climate change and affordability.
In this section, you can read more about the components that make up the UK's current energy mix, and those that will play a new and vital role in the future.
