Electricity generation methods include: thermal power generation, hydroelectric power generation, nuclear power generation, wind power generation, geothermal power generation, etc.
Power generation refers to the production process of using power generation devices to convert raw energy such as water energy, thermal energy from petrochemical fuels (coal, oil, natural gas), nuclear energy, etc. .in electrical energy.
Electricity generation is used to meet the needs of various departments of the national economy and people's lives.
Nowadays, fossil fuels are still used as the main form of electricity generation, but fossil fuel resources are not plentiful and are becoming increasingly depleted. Human beings have graduallystarted using solar energy, wind energy and geothermal energy. , ocean energy and other energy sources to generate electricity.
Methods and processes of energy production
1. Lifting water by wind:
Lifting by wind power has been widely used since ancient times.
2. Wind power generation:
Wind power generation generally has three modes of operation:
(1) It is an independent mode of operation, usually a small generator. is used to produce electricity. One or more households provide electricity, which uses batteries to store energy to ensure energy consumption when there is no wind.
(2) Wind power generation is combined with other power generation methods (such as diesel engine power generation) to provide electricity to a unit, a village or island.
(3) Wind energy production is integrated into the conventional electricity grid to supply the large electricity grid. Often, dozens or even hundreds of wind turbines are installed in a wind farm, which is the main development direction of wind power generation.
3. Sail to aid navigation:
In the development of today's motorboats, in order to save fuel and increase speed, ancient sails have been developed.
4. Wind heating:
With the improvement of people's living standards, the demand for thermal energy for household energy is increasing, especially in the high latitudes of Europe and North America. Drinking water is a large consumer of energy. In order to meet the thermal energy needs of households and small-scale industries, wind heating has been considerably developed.
Detailed information:
1.Advantages
Wind energy is a clean energy source. Wind installations have become more advanced, mass production has reduced costs, and in the right places, wind power is now cheaper than other generators. Wind turbine installations are mostly non-three-dimensional installations that can protect land and ecology. Wind energy is a renewable, clean and environmentally friendly energy source. Wind power is energy efficient and environmentally friendly.
2. Disadvantages
The ecological problem with wind power is that it can disturb birds. For example, grouse in Kansas, USA, gradually disappeared after the emergence of wind turbines. The current solution is to produce electricityicity at sea, more expensive but also more efficient.
In some regions, the profitability of wind power generation is insufficient, and wind power in many areas is intermittent. What's worse is that in places like Taiwan, during summer and when electricity demand is high. ,During the day, there is less wind; we must wait for the development of energy storage technologies such as compressed air.
Wind power generation requires a large amount of land to build wind farms to produce relatively large amounts of energy.
When wind power is generated, the wind turbine will make a lot of noise, so it is necessary to find open spaces to build.
Current wind production is not yet mature and there is still considerable room for development.
