ENERGY “the ability to do work”

Industrial revolution  Coal – tons of energy

Transportation revolution  Oil – moveable fuel

The U.S. gets 94 percent of its energy from nonrenewable sources and 6 percent from renewable energy sources.

New ideas  Biofuels  Gasification  Wind  Solar  Efficiency

New ideas  Biofuels  Gasification  Wind  Solar  Efficiency

Home energy use (national averages)

Home energy use (upper midwest)

Attic Basements Walls Windows and doors U.S. Department of Energy Heat losses

U.S. Department of Energy

Efficiency  Electronics example  Plasma TV  75 watts standby  $65 per year in standby losses

Video games  Nintendo Wii  Sony Playstation 3

Efficiency  Lighting  CFL  75% less energy  Less cooling in summer  $50 per bulb

Determining energy use

Determining cost Item Power needs (watts) A Number of appliances B Hours on per day C Energy/Day= watt-hour = A x B x C = D Kilowatt-hour per day watt-hour x 0.001= D x = E Cost per day E x $.10/kwh = F Cost per year F X 365 = G Incandescent light 75w11075x1x10=750750x0.001=0.75kwh0.75 x $.10=$.075$27.38/year CFL lights15w
