Energy efficiency is widely regarded as the most important first step in making the transition to a low carbon economy. Whilst renewable energy and other measures are also vital components, energy efficiency ensures that valuable energy - whether it be heating, cooling, or electricity - is not wasted. There are numerous energy efficiency technologies, from insulation materials to a plethora of more efficient electrical devices, and more energy efficient vehicles. Explore these pages to find energy efficiency solutions that are right for you. - Description added by: David Lockie

Buildings are where the majority people in modern societies spend most of their time, whether in homes, commercial buildings, industrial facilities or retail complexes. The design and construction of buildings require a large investment of time, money and other resources. Then they require additional resources for running costs and maintenance. Bad design can greatly increase energy consumption over the whole lifetime of the building. Fortunately, good building design can greatly reduce energy consumption during construction and ongoing throughout a building's life. - Description added by: David Lockie

Renewable and alternative energy sources are set to play an increasingly important role in providing the electricity, heat, cooling and fuels that society needs. There is a wide range of energy sources such as solar (both photovoltaic and solar thermal), wind, bio-fuels and biomass, hydro-electric, geothermal and heat pumps. - Description added by: David Lockie
