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

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
