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

The word 'offsetting' simply means 'compensating for'. 'Carbon offsetting' means compensating for carbon dioxide (CO2) that's being generated. We need to compensate for CO2 because of the threats posed by climate change.

Realistically, no-one can expect people to cut out absolutely everything they do that leads to CO2 emissions. We all can - and must - reduce the CO2 we're responsible for, but offsetting means we can compensate for the CO2 we can't avoid creating. Carbon offsetting schemes work by reducing CO2 that would otherwise be created, or by removing existing CO2 from the atmosphere.

And who benefits from the carbon offsetting? Who gets compensated? The answer is Planet Earth - and absolutely everyone and everything that lives on it. - 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
