Using the power of nature

100% renewable electricity

Last year, we sourced all of the electricity we supplied to customers from renewable generators, including more than half from hydroelectric generators and a large proportion from wind.

Based on this success, we are planning to do exactly the same this year. Since we tend to source our power from renewable generators, the average carbon content of our electricity is far below the UK average, giving you peace of mind that you are also doing your bit for the environment.

For electricity we can make active choices about where we source to ensure we keep the carbon content as low as possible, however with gas this is more difficult and the carbon content is more or less the same no matter where it is sourced. Green gas, however, is becoming increasingly viable and we are actively looking at how we can offer our Hudson Energy commercial Green Gas product to our residential customers.

Around 43% 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.
