Given the proper application and products wind can provide 40-100% of your energy needs.
At Green Energy we do an extensive evaluation of your site to determine what resource is available and what turbine would be best suited for your needs. Unfortunately sometimes it just does not make financial sense, and in that rare case we will tell you…we are not out to just sell… but to improve. There are many factors that determine the Return on Investment of your wind system and we will show you them all.
A 10% increase in wind speed results in a 33% increase in power available to the wind turbine’s rotor.
In reality, wind energy is a converted form of solar energy. The sun's radiation heats different parts of the earth at different rates-most notably during the day and night, but also when different surfaces (for example, water and land) absorb or reflect at different rates. This in turn causes portions of the atmosphere to warm differently. Hot air rises, reducing the atmospheric pressure at the earth's surface, and cooler air is drawn in to replace it. The result is wind.
Air has mass, and when it is in motion, it contains the energy of that motion("kinetic energy"). Some portion of that energy can converted into other forms mechanical force or electricity that we can use to perform work.
A wind energy system transforms the kinetic energy of the wind into mechanical or electrical energy that can be harnessed for practical use. Wind electric turbines generate electricity for homes and businesses and for sale to utilities.
There are two basic designs of wind electric turbines: vertical-axis, or "egg-beater" style, and horizontal-axis (propeller-style) machines. Horizontal-axis wind turbines are most common today, constituting nearly all of the "utility-scale" (100 kilowatts, kW, capacity and larger) turbines in the global market.
