R-value: A measure of the ability of a material to resist the transfer of heat. The larger the R-value of a material, the greater the insulating properties.

Solar energy: Electromagnetic energy transmitted from the sun. The amount that reaches the earth is equal to one-billionth of total solar energy generated.

Source reduction: Waste prevention, or consuming and throwing away less by purchasing durable, long-lasting goods, seeking products and packaging that are as free of toxics as possible, and redesigning products to use less raw material in production, have a longer life, or be used again after its original use.

Voltage: The amount of electromotive force, measured in volts that exists between two points.

Watt: The rate of energy transfer equivalent to one ampere under an electrical pressure of one volt. One watt equals 1/746 horsepower, or 1 joule per second.

Watt-hour: A unit of electricity consumption of 1 watt over the period of 1 hour.

Wattmeter: A device for measuring power consumption.
