One large scale wind turbine has a power capacity of 1.5 megawatts (MW). The green energy generated by this turbine each year provides electricity for 1120 households and offsets up to 4960 tonnes of greenhouse gas emissions.
Wind power is the use of air flow through wind turbines to mechanically power generators for electric power. Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation, consumes no water, and uses little land. The net effects on the environment are far less problematic than those of nonrenewable power sources.
