Clegg said that, by 2017, his country expected at least 70 terawatt hours of renewable electricity on the national grid. This is 70 percent of the way toward 2020 objectives of 108 TWh, Bloomberg News reports.
Clegg said the government would put more focus on systems such as biomass, wave and tidal power. London aims to increase the amount of wind and tidal power from 4 megawatts to 300 megawatts by 2020.
"Supporting clean, green, secure energy is the right thing to do for both the environment and the economy," said Clegg.
London last week set up a panel to examine offshore wind and reducing the cost of the renewable energy resource for the country.
Huhne told delegates at the Royal Society that nuclear energy will play a strong role in the energy mix for the country. Huhne said nuclear energy costs around $100 per megawatt hour, compared with $200 per megawatt hour for offshore wind.
