Wind energy or wind power is energy captured from moving air to generate electricity. Wind has kinetic energy in it. The kinetic energy is converted into mechanical energy using a turbine. The mechanical energy can be utilized for numerous purposes including pumping water and grinding grain.

power factor signals efficient utilization of electrical power, while a low power factor indicates poor utilization of electrical power For example, if you had a boring mill that was operating at 100 kW and the apparent power consumed was 125 kVA, you would divide 100 by 125 and come up with a power factor of 0 .80 .

Wind power potential is mostly assessed assuming 1% of land availability for wind farms required @12 ha/MW in sites having wind power density exceeding 200 W/sq.m. at 50 m hub-height. The energy in the wind turns two or three propeller-like blades around a rotor.

The generators in the power stations produce electricity at 20000 volts. This voltage is raised or transformed before it is sent out at 132000, 275000, 400000 or even 765000 volts onto the transmission grid. These very high voltages are necessary to push the required flow of electricity through the wires and keep costs down.

(A kilowatt-hour is 3,600,000 joules 1 watt-second times 1,000—to get from watts to kilowatts—times 3600, the number of seconds in an hour; you can see why the joule is not a practical unit for energy measurements.) If we do a little super-simple algebra, we find that The current flow in amps is the power divided by the voltage.

The energy of this water cycle, which is driven by the sun, can be tapped to produce electricity or for mechanical tasks like grinding grain. Hydropower uses a fuel—water—that is not reduced or used up in the process. Because the water cycle is an endless, constantly recharging system, hydropower is considered a renewable energy.

If you run a 75 volt drive from a 24 volt supply, it will typically work, but you are literally throwing away two-thirds of the mechanical power you could easily get from your system. Moving to a larger motor to get more power is much more expensive than simply supplying more voltage.
