Where can the individual home owner conserve?
The above calculations assume a low price of 6 cents per KWH.
Most areas around the country pay 12-15 cents per KWH.
The average electricity generated by the use of these appliances plus standard household incandescent lighting is about 20,000 KWH per year. At 10 cents per KWH this is 2000 dollars.
The above did not include heating. For most locations, heating requires around 10,000 KWH per year (or more). This means that the typical household energy bill is about $250 per month in many locations around the country. Get some raw data here
This is sufficiently high that it is possible to identify areas where energy conservation is effective and leads to lower utility bills. In fact, most utility companies want their customers to conserve energy and will offer rebates for energy conserving appliances.
Are these utility companies practicing good citizenship or are there other reasons? Well, it costs utility companies big bucks whenever demand exceeds capacity and they would like to avoid that situation at all costs.
Saving dollars on lighting
About 20% of all electrical energy is for lighting.
Fluorescent vs. Incandescent Bulbs --> an example
calculation that Joe and Jane Six Pack never do!

So, over a 10,000 hour period, the fluorescent bulb
has a total cost of $35 and the Incands have a total
cost of $82.50.
