Every time we switch on our lights, turn on our heating, heat water, cook, use any gas or any electrical appliance in our homes, we are often using resources which will not last forever - they are not sustainable. We could also be damaging our natural environment, our health and the quality of life for our children. This problem is known as Global Warming.
Carbon dioxide is the main greenhouse gas which contributes to the threat of global warming.
Some escapes to space but some is trapped by greenhouse gases and returns additional heat to earth. These global changes could affect the air that we breathe, create more cases of skin cancer and spread disease through an increase in dust which itself will be due to drier conditions. Over a quarter of the carbon dioxide we produce in the UK comes from energy used in the home. This equals about 7.5 tonnes per house per year. The average householder uses most energy on heating rooms.
