In the United States, the direct land use for wind turbines comes in at three-quarters of an acre per megawatt of rated capacity. That is, a 2-megawatt wind turbine would require 1.5 acres of land.
One can consider purchasing a small wind turbine if the proposed site has wind speeds of at least 10 mph or 4.4 m/s (meters per second), and the average electricity bill is over a $150 per month. It is important to make any energy conservation and efficiency changes at the site before looking into a small wind turbine.
Per kWh, solar panels are cheaper than wind turbines. Not only is solar a cheaper way to generate power, but solar costs less when it comes to long-term maintenance because wind turbines will require more upkeep due to their many moving parts, which are more prone to breaking.
