To help you analyze the economics of a small wind electric system and decide whether wind energy will work for you, you can use a variety of tools. These tools may be useful in helping you generate the following estimates:

 

Costs

Savings

Cash flow

Output

Electric bills and electric bill comparisons

Wind characteristics

Simple payback in years.

 

Finding these estimates will help you determine whether wind energy is a good option for your site. If it takes too long to regain your capital investment – the number of years comes too close or is greater than the life of the system – wind energy will not be practical for you.
