What are the current shortcomings of wind and solar power?

The shortcomings of these two energy power generation are as follows:

1. Relatively low energy density: The shortcomings of wind and solar power generation are that they have low energy density and require large amounts of energy. Only an area of ​​​​area can obtain enough energy. Wind and solar power generation require more land resources.

2. Restricted by natural conditions: The shortcomings of wind and solar power generation include that the power generation of wind and solar energy is affected by factors such as weather, season, geographical location, etc., and continuous and stable power supply cannot be guaranteed.

3. Energy storage technology is not yet mature: The shortcomings of wind energy and solar power generation include that energy storage technology is not yet mature, and it is difficult to solve the problem of unstable power generation. Before the breakthrough of energy storage technology, wind power and the proportion of solar power generation in the grid is limited.

260 million kilowatt hours.

Taking the Guancun Wind Farm in Inner Mongolia of the National Energy Group as an example, the blades of a 1.5-MW unit can generate about 1.4 kilowatt-hours of electricity per rotation. A 100,000-kilowatt wind farm can generate electricity for one year. The power generation capacity is approximately 260 million kilowatt hours, which can be used by 40,000 ordinary households for one year.

The biggest advantage of wind power is that it is clean, renewable and zero-emission. A 100,000-kilowatt wind farm can save 93,000 tons of standard coal a year, reduce carbon dioxide emissions by 256,000 tons, and reduce dust emissions into the atmosphere. 12,000 tons. Therefore, it has become an important aspect of new energy utilization.
