The Department for Energy and Climate Change (DECC) has released the Digest of UK Energy Statistics (Dukes) which includes data on the UK combined heat and power (CHP) market. CHP capacity grew by almost 3% to 6.1 GW (compared to 5.9 GW in 2011.), meeting 6.4% of the UK's total electricity needs. The increase of 2.8% represents a total electricity generation of 23.4 TWh. CHP schemes also supplied a total of 49,134 GWh of heat, which was an increase of 2% compared to 2011. CHP efficiency benefits led to over 15 million t of CO_2 savings, an increase of 2 million t over the previous year. The increase in use of renewable fuels in CHP contributed to a new record for the production of electricity from renewable sources. Renewables' share of generation increased from 9.4% in 2011 to a new record: 11.3% in 2012, as a result of increased capacity. Heat from renewable sources increased by 7% during 2012.
