The Role of Fan Efficiency in Reducing HVAC Energy Consumption

In 2008, the United States consumed about 100 quadrillion BTU (106 EJ) of source energy to power everything from lightbulbs to automobiles. That is the equivalent of over 29 million kWh, or a per capita energy consumption rate of 11 kW. The vast majority of this energy comes from a limited supply of nonrenewable resources.
