The surest way to reduce your expenses for electricity is to use less electricity. However, whenever energy conservation programs are being considered, all the implications of reducing electricity consumption must be evaluated. For example, the utility bill for heating a building can be lowered by reducing the ventilation. However the reduced ventilation may result in poor indoor air quality thus having negative impacts on the health and productivity of the occupants.
Electricity consumption needs to be viewed in the context of an overall energy management plan.
The challenge is to optimize energy use to increase profitability of your business, industry, or service. For residential customers, the objective is to use energy as efficiently as possible without adverse impacts on health and comfort.
