==Increasing Energy Efficiency==
As mentioned above, there are several ways to increase the energy efficiency of a process by making a simple change. Some processes include energy services that don't require much [[energy]] in the first place, but many of them are quite energy intensive. Changes that can be made to improve energy efficiency vary for what's being done with the energy.

The energy use in new buildings can be dramatically improved using better construction practices like building [[LEED certified building]]s, and [[net-zero building]]s. Improvements can also be made to buildings that currently exist as well. Some improvements include:
*properly [[insulation|insulating]] buildings, like homes, especially the [[fenestration]].
*having an electronic [[thermostat]] that reduces [[HVAC]]'s efforts to control the [[temperature]] when a building (like a home or an office) is unoccupied, or while people sleep. Also turning down the thermostat and wearing warmer clothing.
*[[daylighting]] living and working spaces either with good [[window]] placement or [[hybrid lighting]].
*using [[CFL light bulb]]s or [[LED light bulb]]s instead of [[incandescent light bulb]]s.

Transportation can also have significant improvements to energy efficiency. This usually means less vehicle use:
*improving the [[fuel efficiency]] and [[fuel economy]] of cars.
*carpooling, living close to work, or even telecommuting.
*using public transit.
*flying less, [[airplane]]s use considerable amounts of fuel.

All of the products that are used by people, even food have a fair amount of [[embedded energy]], this can be reduced by:
*reducing the use of [[metal]], and recycling the metal as well.
*reducing the rate at which products are used and recycling products.
*reducing the food waste from spoilage.
*vegetarian diets.

Many programs exist to try to get consumers to use less energy, often electricity specifically. These include [[Energy Star]] and other programs.

See also [[negawatt]]s for the specific term that quantifies how much electricity is not used.
