Installing a wind turbine to vent your roof is an excellent way to save on electricity costs and extend the life of your roof. In most cases, the installation and maintenance costs will pay for themselves within the first five years. You should always try to maintain your wind turbine to ensure its safe operation and perserve the efficiency of the system. It is important to note that greasing the turbine once in a while will help it to turn without any hiccups. In addition, you should also check the tower and the rotor blades of the turbine for indication of corrosion.
