Wind Power

It does work! The wind can supply power on a daily basis, can be used as backup, or even as an alternative energy source. It has few moving parts and the maintenance is minimal. You can call it “green power”.
Power utilities have developed wind power energy for commercial use on wind farms both on land and in the water. The towers that the generators are mounted onto are tall enough to place the turbine itself above all surrounding obstacles so to have the wind be more steady and not subjected to turbulence generated by obstacles in the area.
For a home and as a daily source source wind power can be used to supplement power from the grid as long as the wind blows. To small of a breeze , or to large, does have an impact as to how much power is generated and will be available to use. Batteries can be used for storage and with an inverter for using this power in your home. Wind power efficiency also depends on where you live.
When used as a backup source for power, wind power energy does become very dependent on if the wind is blowing when the power is needed, hard to turn on the wind unlike a gas generator. But if you are looking for an alternative energy source, wind power is a very good idea. Once again, batteries for storage and an inverter can be a very good alternative energy source when the power goes out.
As wind can be called free energy or renewable energy, it is a start towards lower electric bills and some independence from the utility companies. Wind power for homes does work!! There are always start up costs and those can be minimized with government programs.

Is Alternative Energy In our future?

Alternative energy! A renewable energy or is it free energy?

The cost of energy has and will continue to rise. The world has a large appetite and it continues to grow. As countries develop their demand and consumption of electricity and fossil fuels also continues to grow.
What can we do? Maybe turn off some lights, carpool, mass transit if available, lower thermostats for heating or raise them for cooling, or maybe turn off the tv and read a book. We have and continue to enjoy a good life when the power is on. But what if it goes off? Alternative energy sources can help. Wind power, solar power, or one of the newer ideas of making electricity with magnets.
I have lived in New England and gone through blizzards and ice storms. The power has gone off for days and the threat of freezing pipes becomes very real, a real mess to repair and clean up. I have also lived in Florida and have been through several hurricanes and lost power for days. Food goes bad, pools turn green(very bad),generators run, for those who have them, and life changes. Remember that gas stations need electricity to pump gas for those generators!
What of the dangers on the west coast and the midwest. Tornadoes, mudslides, earthquakes, and fires to mention a few. All of these can result in the power going off and making our lives uncomfortable at best.
As an electrician for over 25 years, I have seen what can be considered the waste that has gone into buildings for “backup power”. Thousands of dollars for large generators and the money spent on maintenance of these machines, the extra wiring and components needed, and realize that some of which may never be needed. Hospitals, police departments, fire departments are not included in that statement for those are life safety and protection. But what of office buildings or stores? Why not use alternative energy sources for that emergency. The important thing is to get the people out of the building safely. Also an alternative energy source will also have a payback for the building.

The same can be said for our homes. Would an alternative energy like wind power, solar power, or power from magnets become our “green electricity”. Could these become free energy? Why not?
