How do Green Energy Tariffs Work?
Once signed up to a green energy tariff you still get your electricity from the National Grid in the same way as any other customer. Electricity is generated from a range of sources, some of which are renewable and some of which are not, and is then fid in to the National Grid and then supplied to your home.
What happens is your supplier will match some, or all of, the electricity you use by buying energy produced from renewable energy generators. That's where the renewable energy that comes from wind, geo-thermal, hydro and solar fits in to the equation. The amount of green energy they buy depends on their level of commitment in the tariff.
This all means that the more households signed up to green energy tariffs thera are, the more renewable energy is fed into the National Grid.
