Since microgeneration is, by definition, decentralised, energy is not wasted in transmission and distribution – or as waste heat as with large power stations.
Under the Feed-in Tariff, microgeneration technologies can even provide an additional income stream: for example, a 62 m2 new build end-of-terrace property built to Level 4 of the Code for Sustainable homes will consume 1,993 kilowatt hours of electricity, according to the UK Government’s Standard Assessment Procedure. A typical 2.5 kilowatt PV system, requiring around 20 m2 of roof space, could produce up to 2,125 kilowatt hours a year, allowing excess electricity to be sold to the utility company.
Microgeneration technologies also have an important role to play in helping to tackle fuel poverty: micro-scale technologies such as wind turbines and solar thermal can be effectively utilised to provide cost-secure electricity and heating for fuel poor households, to offset fuel bills whilst making a contribution to tackling climate change. This is particularly important in rural areas, where the favoured means of support is often oil-fired or electric heating. Micro-scale technologies can help to keep the energy costs for vulnerable groups under control
Microgeneration can reduce our dependence on imported fossil fuels, increasing our national energy security.
Microgeneration is a catalyst for cultural change. There are wider benefits than just cost and carbon reduction: consumers with microgeneration installations in their homes become noticeably more ‘energy aware’ and, as a result, patterns of energy usage change for the better
