For the physical concept, see Conservation of energy.

Energy conservation is the practice of using energy resources in a sustainable way by considering which processes are wasteful and addressing those inefficiencies. It is employed in manufacturing, principally for economic reasons.

As the clearly finite quantities of non-renewable resources, such as coal, crude oil and natural gas, are reduced further, the question of conserving remaining stocks until alternatives are found will become more pressing. This can be addressed through conservation of energy, or increased production by other means. The latter process does not consider other environmental consequences of increasing production of energy.

Tips

• Replace incandescent lightbulbs with compact fluorescent lights which use 75 to 80% less electricity
• When using the dishwasher, use the "light" cycle unless you are washing particularly dirty dishes. You'll save water, electricity and time.
• Turn the lights out when you leave a room (but only if they are incandescent - avoid turning fluorescent lights on and off, just leave them alone as much as possible).
• Buy paper towels and toilet paper made of recycled paper.
• Insulate your home properly.
• Avoid un-necessary journeys.
• Avoid flying (if possible take an alternative mode of transport).
• Avoid air conditioning, or use it correctly (close doors and windows etc).
