We bought our home last summer, and haven't done any renovations to it yet. The people who had it before us, did have the green insulation put in, and it really helps with our heating bills. We live in North Dakota, where it's really cold most of the winter, but we are paying about the same for heating our house, as what my parents pay in Missouri, where it's usually about 20 degrees or more warmer! My parents house only has about 100 square feet more of living space, too.

The only thing we've really done to conserve electricity is that we only use florescent light bulbs, but that is all we've used for most of the three years we've been married anyway.
