Heating and cooling are typically extremely energy intensive technologies. In the United Kingdom the majority of heating in our homes and buildings is provided by burning natural gas. Renewable energy technologies such as solar heating, or heat pumps provide a sustainable low carbon alternative. Condensing boilers, and combined heat and power (CHP) also offer significant energy savings. In this circumstance energy that would have otherwise been wasted (which happens in traditional power plants) is instead used by the local community via a district heating scheme. Alternatively, a micro CHP system (such as a residential fuel cell, or Stirling engine) produces both electricity and heat to serve a local heat demand i.e. for a particular building. Energy efficiency technologies such as low carbon ventilation solutions can reduce the energy demands of buildings. - Description added by: David Lockie

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
