Commercial Wind Power

Commercially, wind power is harvested onshore or offshore. Onshore wind farms are populated with wind turbines 350 feet high from their base to the tip of the up pointed blade. The increasing large turbines visual impact along with the need for large expanses of land has slowed down onshore wind farm expansion somewhat.

These issues are not such a problem with offshore wind farms. The issues are justification for the extra expense of offshore wind farms that include complex installation and maintenance.

Studies have shown as that offshore wind farms can act as artificial reefs and as a result, increase fish populations that are attracted to the food supply. But there are also concerns that the noise and vibration produced from the offshore wind farms will disturb sea life.

For these reasons, the first prototype floating offshore wind turbine platform has been designed, currently floating in Norway, supporting a 2.3 MW turbine and displacing 5,300 tons.

But commercial wind power works on a smaller scale as well. The Proven Energy 15Kw Grid Connect Wind Turbine is a good-sized wind turbine for an office building of 2000+ sq.ft. It produces an annual output of 15,00-30,000 kWh. The advantage of this relatively small wind turbine is that it can be installed in a residential setting and the mast is self-supporting and has no guy wires. The Proven Energy 15Kw Wind Turbines blades will twist to limit the power in winds of over 25mph, reducing the rotor diameter and giving a constant rpm to avoid power surges and over-charging. The low speed means more durability and the galvanized steel structure and thermoplastic glass composite blades are strong, and able to withstand strong winds of up to 156 mph.

The global market for commercial wind power is growing at a 28% annual growth rate and the potential for commercial wind power is enormous. There is enough wind power to provide sustainable electricity for the whole world. It also exceeds our needs. There is a potential 72 terawatt (TW) of energy in wind and currently the globe consumes, on average, 15 TW. Wind power is all around us, waiting to be harnessed.
