Assessing the Impact of Energy Efficiency Technologies on Energy Consumption

Incandescent light bulbs are an inefficient lighting technology that wastes most of the energy they consume as heat.

Energy efficiency technologies reduce energy consumption by using less energy to perform the same task.

Energy efficiency technologies reduce greenhouse gas emissions by using less energy.

LEDs are the most energy-efficient type of lighting, using up to 80% less energy than incandescent light bulbs.

Refrigerators are typically the largest energy consumer in a household, accounting for about 15% of total energy use.

The Energy Star program is a government program that sets energy efficiency standards for appliances and electronics.

The average annual energy consumption of a U.S. household is about 10,000 kWh.

Leaving the air conditioner on all day is a way to increase energy consumption, not reduce it.

The payback period for a typical energy efficiency investment is about 2 years.

Wind turbines are a type of renewable energy technology, not an energy efficiency technology.

Heat pumps are the most energy-efficient way to heat a home, using up to 60% less energy than electric resistance heating.

Evaporative coolers are the most energy-efficient way to cool a home, using up to 90% less energy than central air conditioning.

Time-of-use pricing is a type of electricity pricing that charges different rates for electricity at different times of day, not an energy efficiency program.

All of the above are ways to reduce energy consumption in a commercial building.

Installing a programmable thermostat is the single most effective way to reduce energy consumption in a household.
