This small book is to the point and tells how I have reduced the electricity that I have used to also reduce my bill by about 75% which seems a lot but is acheivable . most changes won`t cost anything but depending on your budget there are things that you can do to suit your own needs. If you have ever been camping away from electricity you already know most of the tricks and it can be fun, especially when the bill comes in to find out how much you have saved ..
