The state of the environment in which we live is of the highest importance – without it we cannot live, and if it is not functioning normally our lives become increasingly difficult. The number of people on the planet and the accelerating rate of individual resource consumption are having negative or disruptive effects on the environment. Global warming and climate change are now global challenges attracting much media attention. Resources such as drinkable water, food and non-polluted environments are all becoming more dependent on technology and competition is growing for these resources. Thus the decisions that we need to make on our journey to becoming 'low carbon' should always be taken with environmental impacts in mind. - Description added by: David Lockie

Electricity is fundamental to modern societies. It is the backbone to nearly all other technologies and we use it daily in lighting, appliances, communications and healthcare. Currently most electricity is generated in centralised, large-scale power stations fuelled by fossil fuels, uranium (nuclear power) or through renewable or alternative energy sources such as wind or hydro-electric power. It is becoming increasingly clear that we need to secure long-term, cost-effective and sustainable alternatives to fossil fuel power stations to cover both current demand, and future growth. There is an urgent need for open debate and consensus on the future of electricity generation as decisions are being made now that will still need to be in place in thirty years time, when the world might look radically different from how it does now. - 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
