Ecotricity state that 100% of the electricity that it supplies is from renewables – see energy mix graph below since 2015 [http://electricityinfo.org/supplier-fuel-mix-graphs/].
In 2017, 78.34% of the electricity sourced by Ecotricity was from offshore wind, 21.59% was from onshore wind, and 0.06% was from hydro generation.
“…we turn our customers’ bills into new sources of green energy in Britain. … We generate around a fifth of the green electricity we supply ourselves through our own growing fleet of green energy parks, and the rest we buy from other green generators. Our aim is to eventually make all of our own energy – so that all the electricity and gas we supply to our customers comes from our own wind, sun and green gasmills.”
By 2015 Ecotricity owned 87.2 MW of installed wind capacity and 1 MW of solar PV capacity.You can get a quotation (approximate cost) for Green Electricity and/or Green Gas at https://www.ecotricity.co.uk/for-your-home/quote-and-switch
Good Energy state that 100% of the electricity that it supplies is from renewables – see energy mix graph [ http://electricityinfo.org/supplier-fuel-mix-graphs/ ]. Currently 18% is from solar, 57% from wind, 5% from hydro and 20% from bio generation. (2019)
We purchase only 100% renewable electricity from around 1,400 generation locations providing a mix of onshore and offshore wind, solar, hydro and biogeneration. In 2016, we sourced enough electricity in this way to meet around 75% of our customers’ demand with the balance matched by the output of our own generation solar and wind sites.
“Since 2011, Good Energy has developed renewable energy sites with a total capacity of over 150MW.”
Having sold some sites, in 2017 Good Energy owned 57.5MW of electricity capacity made up of 17.4MW onshore wind and 40.1MW solar PV.
