From energy-saving refrigerators, low-consumption automobiles, and intelligent building management systems to resource-saving production processes in industry, energy efficiency is a versatile topic that is - and will remain - of great importance in all areas of our everyday lives. Solar technologies are characterized as either passive or active depending on the way they capture, convert and distribute sunlight and enable solar energy to be harnessed at different levels around the world, mostly depending on the distance from the equator.

Typically these two technologies are used separately (or only placing them in parallel) to produce hot water 133 In this system the solar moving house electrical certificate 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.
