Old drafty windows? Don't fret!

Here's a great post from the National Trust for Historic Preservation listing many reasons why retrofitting historic windows to improve their energy efficiency can be as good or better than replacement windows. Besides preserving the look and feel of your house, not contributing to landfills, and being a better return on investment, the bonus reason at the end is central to the whole point as far as I am concerned... 

There are several options ranging from simple weather stripping, traditional exterior storm windows, insulating cellular window shades, interior insulating panels, temporary cling film, and combinations of these that can greatly improve your window's efficiency and maintain the traditional appearance of the building.
