Our Energy

At Green Star Energy we do our best to source as much electricity as we can from renewable generators and so minimise the carbon content of electricity we supply to homes across the UK.

What sources of electricity does Green Star Energy use?

Last year we managed to source over 99% of our electricity from renewable generators meaning the average carbon content of the electricity which we supply is far below the UK average. Of the Renewable electricity which we supplied around 50% was sourced from Hydroelectric generators and a further 40% was from Wind generators.

*Our Fuel Mix Disclosure follows Ofgem’s guidelines which displays our Fuel Mix for our entire electricity supply license which include domestic and non-domestic electricity volumes. We are speaking with Ofgem to see if there is better way of presenting our FDM which is more representative of our Domestic Fuel Mix.


What about Gas?

For electricity we can make active choices about where we source to ensure we keep the carbon content as low as we can. With gas however the carbon content is about the same no matter where you get it from. About 38% of gas supplied to the UK is still extracted and piped to your home from the domestic sources in the North Sea, though this is likely to reduce in the future. The majority of imported gas is sourced from Norway with smaller amounts piped in from the Netherlands and Belgium, the rest is shipped in as Liquefied Natural Gas from more distant sources including Qatar and North Africa.
