260 million kilowatt hours.
Taking National Energy Group's Guancun Wind Farm in Inner Mongolia as an example, the blades of a 1.5 MW unit can generate about 1.4 kilowatt hours of electricity per rotation. The kilowatt wind farm can produce electricity for a year. The power generation capacity is about 260 million kilowatt hours, which can be used by 40,000 ordinary households for a year.
The biggest advantage of wind energy is that it is clean, renewable and emission-free. A 100,000 kilowatt wind farm can save 93,000 tons of standard coal per year, reduce carbon dioxide emissions by 256,000 tons, and reduce dust emissions into the atmosphere by 12,000 tons. It has therefore become an important aspect of new energy use.
