WIND ENERGY

By: Patricia Artes, Erin Hall, Jared Swain, and Chris Cole.

MAP OF THE USA AND NORTH CAROLINA

Texas has the most wind energy with nearly 36 million megawatthours (MWh) of electricity. IOWA comes in second with more than 15 million (MWh), followed by California with, Oklahoma, Illinois, Kansas, Minnesota, Oregon, North Dakota, And Wyoming.

Wind Energy in North Carolina is being used for homes, farms, and businesses, schools, and utilities interested in producing clean, independent electricity.

DEVELOPMENT OF THE TECHNOLOGY

Since early recorded history, people have utilized wind energy. It propelled boats along te Nile River as early as 5,000 B.C and helped Persians pump water and grind grain between 500 and 900 B.C. Then, the use of windmills were used extensively in food production.

Today, wind-powered generators operate in every size range from small turbines for battery charging at isolated residences to large, near-gigawatt-size offshore wind farms that provide electricity to national electric transmission system.

PROCESS

Wind energy/turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.

CONCERNS FOR WILDFIRE, ENVIRONMENT

Birds can't rest/nest on them because modern turbines have solid instead of latticed towers. They have really sharp blades that moves around 150 to 200 mph that could cut the animals and kill them.

COSTS

A 10 KW wind turbine costs approximately $48,000-$65,000 to install. The equiptment costs about $40,000. Towers without guy wires are more expensive than guyed towers. It can cost $350,000 for the government to install wind turbines and create the project to sustain the energy usage.
