6 FAQs about [Switching from thermal power to wind power]

Can wind and solar power generation replace thermal power generation?

Under a certain scale, the increase of wind and solar power generation can effectively substitute thermal power generation and strive for space for its own development. However, if the wind and solar power generation exceed certain level, the wind and solar power generation will promote the growth of thermal power generation.

How can we maximise on excess wind energy?

There are a number of ways that we can maximise on excess wind energy: In order for homes and businesses to use cleaner, greener energy, more renewables – such as wind power and solar power – will need to be connected to the electricity grid.

How does new energy affect thermal power?

Contribution of this research The rise of new energy will lead to a decrease in the scale of thermal power, which will result in a decrease in its flexibility supply. The proportion balance between new energy and traditional thermal power is a direct issue that needs to be faced at present.

Why is thermal power a key component of the energy system transformation?

Improving the flexibility of thermal power sources, as a short- to medium-term solution, is an important component of the energy system transformation with an increasing share of renewable energy. It supplements other flexibility solutions such as energy storage, demand-side management and increased interconnection.

Is there a balance between New Energy and traditional thermal power?

The proportion balance between new energy and traditional thermal power is a direct issue that needs to be faced at present. The low-carbon goal cannot be achieved if the proportion of new energy is too low, while the stable operation of the power system cannot be guaranteed if the proportion of new energy is too high.

How does a thermal power plant work?

The fuel source can be coal, natural gas, or nuclear fission, but the process is similar – and very inefficient. The majority of the energy that goes into a thermal power plant is vented off as waste heat. Additional minor losses come from the energy used to operate the power plant itself.
