What is the maximum proportion of wind energy in a region?

Introduction What is the maximum share of wind energy in a region? In 2009: thermal power accounted for about 80%, hydropower about 16%, the rest being wind, nuclear, etc. Today, we are vigorously developing clean energy.

What is the maximum proportion of wind energy in a region?

2009:

Thermal energy represents about 80%, hydroelectricity about 16% and the rest is wind, nuclear, etc.

The Clean energy is now being vigorously developed, the proportion of thermal energy will decrease, the trend is to increase the proportion of clean energy such as hydropower. (Internet search China's electricity supply structure)

In 2010, the annual electricity consumption was 4 trillion kWh. (Internet search: China's annual electricity consumption)

It is not possible to stop coal-fired power (thermal power):

1. Developing other clean energies requires a process. The construction cycle of a hydroelectric power station lasts from 5 to 20 years. Although many power plants can be built at the same time, it also takes time. The selection requirements ofsites for nuclear power are relatively strict, safety must be considered, and development will not be too rapid. Wind energy reserves are limited.

2. Thermal power has advantages that other electric power does not: stability and few restrictions on plant site conditions. Most hydropower is seasonal, and electricity production varies significantly between wet and dry periods. Wind power is also limited by the uncertainty of wind power.

3. Linked to the local economy. This involves the sale of coal companies as well as the operation and development of power companies. By shutting down coal-fired power, coal mines lost huge, high-quality, stable customers. Electric power giants that focus primarily on thermal power cannot get into the business.development of other sources of energy if they don't have food to eat, they certainly won't.

4. Disadvantages of nuclear energy. The cost of power plants is higher than that of thermal energy. There are no international conclusions on the safety of nuclear energy. As a large amount of cooling water is required, it can only be built in areas where water is abundant and seismic intensity is low. The biggest problem is that the treatment of nuclear waste currently involves landfilling or returning it for disposal. Landfilling is the stupidest method and environmental pollution is inevitable; Recycling requires specialized technology, equipment and processing plants. Current processing capacity is too low and new construction and expansion will take time. (Research on the Internetof the disadvantages of nuclear energy and the treatment of nuclear waste)

The impact of this proportion is as follows:

1. stronger winds in spring and autumn, so in these two seasons, wind power generation will be relatively high, while in summer and winter, due to the weakening of wind power, the wind power production will decrease accordingly in summer and under the sun; days, because the duration of sunshine is long and the solar radiation is very strong. In winter and on cloudy days, photovoltaic energy production will decrease.

2. The volatility of wind and photovoltaic power generation is mainly affected by weather conditions, such as changes in wind speed, cloud cover, etc., which will lead to unstable power generation.
