Not much to say about this today. In most of the country it is too cold to do anything about it anyway.

The top energy-saving home improvements
By Laura A. Bruce • Bankrate.com
These are the top single-family home energy-efficiency improvements that reduce energy bills. The return on investment (ROI) is annual, based on 7 cents per kilowatt-hour.
Example: A homeowner spends $500 to insulate an attic that has no insulation, and saves $25 per month on energy bills. $500 divided by $25 per month equals 20 months. This means the investment paid for itself in 20 months and, for the next 30 years, gives monthly dividends of $25 per month in lower energy bills. The $25 grows each time there is a rate increase.
