The maximum single unit capacity of wind power generation is currently 3MW, and the maximum single unit capacity of offshore wind power generation is currently 10MW.
The wind turbine only charges the battery, and the battery stores the electrical energy. The amount of electrical power people ultimately use is more closely related to the size of the battery. The size of the power mainly depends on the size of the air volume, not just the size of the machine head power. In the Mainland, small wind turbines are more suitable than larger ones.
Because it is more easily driven by small winds to generate electricity, continuous small winds can provide greater energy than temporary strong winds. When there is no wind, people can still use the electricity brought by the wind normally. In other words, a 200W wind turbine can also be used with a large battery and an inverter to obtain a power output of 500W or even 1000W or even greater.

China’s new energy strategy has begun to vigorously develop wind power as a focus. According to the national plan, in the next 15 years, the national installed wind power capacity will reach 20 to 30 million kilowatts. Based on an equipment investment of 7,000 yuan per kilowatt of installed capacity, according to "Wind Energy World" magazine, the future wind power equipment market will reach 140 billion yuan to 210 billion yuan.
The development prospects of China's wind power and other new energy power generation industries are very broad. It is expected to maintain rapid development for a long time in the future. At the same time, profitability will also steadily increase as the technology gradually matures. After 2009, the total profit of this industry will maintain rapid growth, and the growth rate will also reach more than 60%.
At the current stage of development of wind power, its cost performance is forming a competitive advantage with coal power and hydropower. The advantage of wind power is that every time the capacity is doubled, the cost drops by 15%. In recent years, the growth of world wind power has remained above 30%. With the localization of China's wind power installed capacity and the scale-up of power generation, the cost of wind power is expected to drop further. Therefore, wind power has begun to become a place for more and more investors to pursue gold.
