Energy efficiency

Energy efficiency + renewable energy = sustainable energy

Energy efficient lighting

The most cost effective means of meeting our energy needs whilst tackling climate change is by using energy more efficiently and utilising renewable energy. Improved building design, and improvements to existing stock by using:- higher levels of insulation, active and passive solar heating techniques, energy efficient boilers, better heating controls, natural lighting, integral power generation, etc. all contribute to reducing energy demand.
More energy efficiency can be gained by decentralising power generation. Large power stations can waste two-thirds of the energy they generate in the form of heat. Because of their remote situation this heat cannot be recovered for useful purposes. A reduction in generation and transmission losses can be obtained by building smaller localised combined heat and power plants (CHP). CHP plants both generate electricity and supply heating for the locality.
