Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty’s Government how much energy is released into the atmosphere in the form of waste heat by the UK's electricity generating industry annually.

Analysis from the Association of Decentralised Energy estimates that just under 10% of UK power stations capture their heat currently. The UK has a number of policies in place to promote the use of heat produced as a by-product from the UK’s electricity generation industry. These include incentives for good quality combined heat and power (CHP), as well as the £320m Heat Networks Investment Project which will encourage capital investment in hundreds of heat networks, which can use not only heat from power stations but also others sources of waste heat such as industrial processes.
