According to Energy Star,
if all of the households in Minnesota changed just one incandescent light bulb to an Energy
Star qualified bulb, the combined individual efforts could save up to
106 million kilowatt-hours of electricity per year. This is enough energy to
light all the households in St. Paul for nearly 180 days. Based on the average
electrical rate in Minnesota, the amount of energy saved would reduce household
electrical bills by a combined total of $9 million a year. AND, this
simple change would prevent nearly 163 million pounds of greenhouse gas
emissions each year which is the equivalent to removing the annual emissions of
14 thousand cars from Minnesota roadways.
