Increasing energy sustainability

Carbon footprints
Everyone uses energy, but if people used less then it would be possible to reduce the amount needed. Energy use can be measured through A measure of how much carbon is used through the activities of a person, company or country.. A bigger carbon footprint means that more energy is used and therefore more carbon is produced. Carbon footprints take into account:
- Goods and products - energy is used to produce goods and so it is better to buy less. Owning electronic devices can be bad, especially if they're often left on standby rather than being switched off.
- Transport - walking or using public transport is best, because travelling by car uses petrol or diesel per person. Aeroplanes use much more fuel than other forms of transport.
- The distance food travels from producer to consumer. - buying local food can use less energy as food is transported a shorter distance. However, sometimes food grown locally requires a lot of energy to produce because of the bright, warm conditions needed to grow food in huge greenhouses all year round.
Energy conservation
New homes built in the UK have lots of energy-saving measures, like loft and wall Things which protect by preventing a loss of heat., radiator A device to switch radiators on and off depending on the temperature. and A meter that sends readings to the electricity supplier and monitor household energy use. that monitor energy use. This is because any homes that are built or rented out have an energy rating, where A-rated homes use the least energy and G-rated homes use the most.
Businesses and organisations like to be energy efficient because it saves money. Public buildings like schools and hospitals have to display an energy certificate to show how much energy they use.
Local councils encourage people to use sustainable methods of transport. This could be through providing Trains, buses and taxis that are available for the public to use for a charge., creating A special lane on a road that only cyclists are allowed to use. or introducing The payment due if a private vehicle drives in a defined area during certain times of the week.. London has all of these measures, plus an underground train network and a cycle hire scheme.
Better technology
Modern life is dependent upon the use of electrical items. There is a system that rates household appliances, like washing machines and dishwashers - A+++ items use the least electricity and D items use the most. This helps people to choose products that use less energy.
Many cars now use less fuel and some have batteries so that they can be charged using renewable electricity. The Vehicle Excise Duty (VED) is a tax for car owners. People who drive less energy efficient cars pay a higher VED.
