If environmental costs are considered, renewable energy power generation, especially wind power generation, is undoubtedly much more cost-effective than coal power generation. In a surprising twist, however, solar power is more expensive than wind power and even hydropower, at least in the European Union, according to a new analysis.
Analysis shows that solar power generation has the highest cost, which is much higher than wind power generation and close to the cost of nuclear energy. Gardner believes that the reason is that most solar panels in the world are made in China, and China's power industry is a coal-intensive industry. The consumption of metal resources also makes solar power generation more expensive than wind power. But Gardner pointed out that solar technology is still improving and is now more cost-effective than in 2012
The reason why the Gansu wind farm can become the largest wind farm: high wind energy density, The climate environment for wind power generation is good.
Gansu wind farms have superior conditions for developing the wind power industry, and the wind energy density is high. The climate environment for wind power generation is good, the extreme low temperature is not less than minus 30 degrees Celsius, the air humidity is low, and there are no natural disasters such as salt spray and freezing, which is conducive to extending the life of the wind turbine; the construction conditions of the wind farm are good, and the wind farm is easy to develop and construct.
Wind farm production process:
In the production process of wind farms, the principle of wind power generation is relatively simple. In the process of wind power generation, a wind turbine is required. When the air cuts into the wind turbine blades, it will generate resistance or lift. Under the action of these two forces, the blades of the wind turbine rotate, thereby driving the generator to generate electrical energy.
In the production process, there are some other auxiliary production systems. These systems coordinate and cooperate with each other to make the wind farm production process more energy-saving and environmentally friendly, and the resource utilization is more reasonable and perfect.
