The news is good
for those of us who pay gas and electric bills -- homes have become much more
energy efficient in the past 20 years.
How much more efficient? A typical three-bedroom home located in
California's Central Valley -- if built before 1977 and never improved -- can
cost a homeowner as much as $2,700 a year just to heat and cool.
Heating and cooling bills for the same 1,700-square-foot house, built to
today's California energy standards, should be only $700 a year. That's a cost
savings of nearly 75 percent!
And by using existing technology to go beyond the standards, that same
size-single-family home can be built so that its heating and cooling costs are
reduced to around $250 a year!
Of course, heating and cooling accounts for, on average, just 30 percent of
the energy used today in most homes. The remainder of the utility bill goes to
heat water, cool and cook food, wash and dry clothes, operate lights, and run
appliances like televisions and vacuum cleaners. Fortunately, around the home
there are numerous ways to use energy more wisely.
Just as houses are designed to be more efficient today, modern home
appliances are improved. New refrigerators, for example, can use 60 percent
less electricity than those built 20 years ago.
California has led the fight for energy efficiency, with good reason: each
year from 1980 to 1992, our state's population increased by 850,000 people.
That's like adding the entire population of the State of Montana to California
each year for 12 years!
To insure an adequate supply of energy to such a rapidly-growing state, the
California Energy Commission set out to cut energy waste. By making the most
of existing energy supplies, we could forestall the addition of new power
plants. That's why, in 1977, the Commission established our state's first
Energy Efficiency Building Regulations.
Since these standards went into effect, they have saved Californians an
estimated $10 billion in energy costs.
Here are some interesting Energy Characteristics of American Households
from the U.S. Department of Energy's Energy
Information Administration.
-
92% of all households use some type of fan; 58% use exhaust fans and 9%
use attic fans
-
81% of all households have roof/ceiling insulation
-
70% of all housing units have insulation in outside walls
-
48% of all housing units have a garage or carport
-
47% of all households have trees shading the afternoon sun
-
29% of all households use a gas outdoor grill (with 90% of these using
propane)
-
8% of all households use a heat pump
- 1% of all households use solar energy
