I really need some help here with this, I live in a 500sqft house in Northern California. Now this house is on a raised foundation(i guess that's what you call it?) has old wooden windows and wood floors. We also have a wood stove that we use most of the time in the winter and sometimes use space heaters for a bedroom.

Last winter our energy use was anywhere from 97 dollars to 170 dollars. I wouldn't be so alarmed but these prices are outrageous for this small of a house, PG&E says the average cost in the winter for this same size house should be no more than 75 dollars on high month.

What's even more ridiculous is in the summer, we ran the window AC almost 24/7 for about 3 and a half months and the bill was no higher than 80 dollars.

Also, the water heater we have is a 40 gallon electric unit, and everyone has said this size is for about a 1,000sqft to 1,200sqft house. But at this time I cannot afford to change it out.

PG&E came out last winter and "winterized" the house, put a rubber strip around the door and wrapped the water heater pipes but that was it. No change in any costs.

I know this post is all over the place, but what can I do to lower my costs and keep my house warmer?

Feel free to ask any other questions and if needed I can post some pictures when I'm home later.

Here's the best picture I can show of the type of house ATM. Link
