Britain is now obtaining more power from zero-carbon sources than fossil fuels for the first time since the industrial revolution. This milestone was passed for the first 5 months of 2019.
Latest figures from the Internation Energy Agency show that electricity generated in the UK continues to get cleaner, with emission rates per unit of electricity at their lowest for over 100 years. The biggest contributor to this is the development and continued investment in offshore wind. In fact, figures show that the UK has the largest offshore wind capacity in the World, and has done so since 2008.
As fossil fuel consumption for domestic heating is gradually phased out we will switch to an electric economy. Note that the UK's Clean Growth Strategy, recently published by the Department for Business, Energy & Industrial Strategy (BIES), lays forth the objective of phasing out fossil fuel installations in new build within the next decade.
