Britain announced plans on July 15 to slash emissions by increasing the use of renewable energy to generate one third of the country's electricity needs by 2020.
Energy Secretary Ed Miliband said tackling climate change would require "comprehensive changes" in Britain's economy and society, as he unveiled proposals to cut emissions from transport, agriculture and industry.
Forty percent of electricity would come from renewables such as wind and wave energy, and nuclear and "clean fossil fuels," he said. Explaining how the targets would be met, Miliband said that by 2020, 30% of electricity would come from renewables and a further 10% from nuclear and coal plants where emissions were captured and stored.
The fuel sources were "the trinity of low carbon and the future of energy in Britain," the minister said.
Britain has committed to cuts of 34% in emissions by 2020, and has signed up to EU targets to source 15% of all energy from renewable sources by the end of the next decade.
It has already reduced greenhouse gases by about 21% compared to 1990 levels, including cuts that companies have purchased through the EU Emission Trading Scheme (ETS).
The government has come under fire over the potential costs of "greening" the British energy sector, but Miliband insisted it would be less costly than feared because of technological advances. He said the new measures would not increase energy bills before 2015 but admitted bills would rise afterwards by as much as eight percent. But there will be some grants available to make homes more energy efficient.
Miliband also said up to 400,000 jobs could be provided by green jobs from sectors such as low-carbon industry, recycling and waste.
On the day Britain's jobless rate surged to its highest for 12 years, Business Secretary Peter Mandelson said: "The transition to a low-carbon economy provides an important part of the answer of where the future jobs are going to come from."
