Some Quick Wind Energy Facts
by Dennis Hopkins
The controversy over using wind energy has created some confusion over the real wind energy facts. People all over the world have used it for centuries, and ancient windmills still dot the countryside in many rural areas. Today's energy crisis has made the idea of wind power more popular than ever, and modern technology has made it far more efficient and practical. A few acres of elegant, tall wind towers can create enough energy to replace a standard traditional petroleum power plant.
Constantly Renewable
Wind energy facts always begin with the renewable nature of the wind as a power source. There is not a part of the world that doesn't have enough wind to turn a modern turbine to create power. The latest technology has made the windmills so sensitive that they will turn and create energy from the slightest breath of wind. The wind can power the turbines day and night. Wind power plants have storage batteries that keep excess energy on hand if there should be a lack of wind for some reason. Wind is a constantly renewable resource that never needs to be replenished and never runs out.
Inexpensive to Maintain
The biggest drawback is that wind energy costs a great deal to set up. Special power plants need to be built, and then the turbines have to be erected as well. There is an additional cost when you consider the acres that need to be purchased for the wind turbines. Once everything is set up, however, wind energy requires virtually no maintenance costs. The land between the turbines can be used for agriculture or ranching, and the power plant virtually runs itself. The technology is so simple that it doesn't require highly trained engineers to keep it running throughout the year. Eventually the low maintenance costs will offset the initial setup costs.

Great Northern Hydroponics (PART 7 OF 9)

Great Northern Hydroponics, a division of Detroit-based Soave Enterprises, installed the 12-megawatt commercial greenhouse power plant at Soaves sprawling, 55-acre tomato greenhouse complex in Kingsville, Ontario. The complex is located near Lake Eries north shore in the Leamington region, about 350 kilometers (km) west of Toronto and about 50 km east of Detroit.
The high-efficiency onsite power plant, powered by four of GE Energys Jenbacher gas engines cogeneration modules, was among seven natural gas-fueled combined heat and power (CHP) projects approved by the Ontario Power Authority in 2006 to showcase how advanced cogeneration technologies could help make industrial plants more energy independent, improve local grid reliability and support Canadas clean and renewable energy goals.
Surplus power from the greenhouse power plant is being sold to the local grid under a 20-year contract with the Ontario Power Authority. The plant supplies enough electricity to Ontarios transmission grid to power 12,000 to 15,000 Canadian homes annually.
In addition to generating power and heat to support greenhouse operations, the power plant also treats the gas engines exhaust, enabling CO2 from the exhaust to be recycled and applied as a special fertilizer to enhance greenhouse crop production.
Because CHP plants are inherently more energy efficient than separate systems to create electrical and thermal power, less fuel is consumed to produce the same amount of power. As a result, cogeneration can help to lower regional industrial emissions associated with energy production.
