Simply put, energy efficiency means using less energy to get the same job done - and in the process, cutting energy bills and reducing pollution. Declines in energy intensity are a proxy for efficiency improvements, provided a) energy intensity is represented at an appropriate level of disaggregation to provide meaningful interpretation, and b) other explanatory and behavioral factors are isolated and accounted for.

Typically these two technologies are used separately (or only placing them in parallel) to produce hot water 133 In this system the solar energy efficiency program manager (you could check here) thermal panel performs the function of the low temperature heat source and the heat produced is used to feed the heat pump's evaporator.

In essence, the UK energy market will either see the energy price cap temporarily suspended so that energy suppliers can recover, which would mean that consumers end up paying the cost, or the energy price cap remains in place and energy suppliers that cannot survive the competition go bust.

You can compare energy prices by providing your postcode and usage details (starting with the postcode entry box at the top of this page) so we can show you the deals available in your area along with the estimated savings based on your current usage.
