How much money will Vera save me on my energy bill?

Naturally this depends on many factors, including how much your local utility charges you for electricity. So, we'll present a hypothetical example here based on a family in California with a 3 bedroom home, with prices as of October, 2008.

Your energy usage is measured in Killowatt hours (Kwh). There are 720 hours in a 30 day month, so a 100 watt light, if left on all month, will use 72 Kwh. In California, like in most places, each home is allowed to use a very modest amount at a low price, which right now is 11 cents per Kwh. But, you're only allowed to use 317 Kwh per month at the base price. Once you go over that base level your rate goes up to 35 cents per Kwh. To give you an idea how low the base level you can use is, 317 kwh, if you have more than 4 lights on you will be exceeding your base amount. Your continuous usage can only be

But, chances are you use more than the modest amount, so your rate goes up.

So, if

In California, like in most places,
