What role does National Grid play in my energy bill?
We receive a lot of questions about how your household energy bills are made up, and which parts of your bill relate to National Grid.
The bill you receive from your energy supplier is made up of a number of separate charges. Some of these charges are based on the different stages through which electricity makes its way from the producers to your home, so we explain this journey and where National Grid fits in.
Clean energy: what happens when the wind isn't blowing and the sun isn't shining?
To achieve net zero carbon emissions, more of our electricity needs to be generated from renewable energy sources – two of the most popular being wind power and solar power.
Because energy generation from these sources can be intermittent, we receive a lot of questions about where clean electricity will come from when the sun isn’t shining and the wind isn’t blowing.
Net zero and carbon emissions
You may have heard the term net zero, but what does it mean? And why is it so important that we reach net zero carbon emissions? Find out the answers to these questions and much more in this section.
Renewable, clean and green energy
What’s the difference between renewable, clean and green energy, and how are different energy sources helping the clean energy transition? Find out more in this section.
