The use of green energy can effectively reduce air pollution and improve air quality. For example, green energy technologies such as solar energy, wind energy, and hydropower do not produce air pollution, help improve air quality, and reduce the risk of environmental pollution.

Maintain water resources and develop sustainably

Traditional thermal power plants consume a large amount of water resources and discharge wastewater into the environment, causing water pollution and affecting the sustainable use of water resources. In addition, the construction of reservoir-type hydropower plants may also lead to uneven distribution of water resources and affect the water supply in downstream areas.

The development of green energy helps reduce dependence on water resources and protect water resources. For example, green energy technologies such as solar and wind power generation do not require large amounts of water resources and can effectively reduce water pollution, protect water resources, and promote the sustainable use of water resources.

Protect biodiversity and maintain ecological balance

The extraction and burning of fossil fuels will destroy the natural environment, cause habitat loss, reduce biodiversity and other problems, and affect the ecological balance. For example, coal mining can cause soil erosion, water pollution, and air pollution, destroy the ecological environment, and affect the survival of living things.

The development of green energy can effectively protect biodiversity and maintain ecological balance. For example, green energy technologies such as solar and wind power generation require smaller land areas and have less impact on the environment. They can effectively protect biological habitats and reduce the impact on biodiversity.

Regional distribution and resource limitations of green energy

The development of green energy is closely related to geographical distribution, and resource limitations have become a key factor affecting its popularization. The following will discuss different types of green energy:

solar energy

• Advantages:Solar energy resources are abundant and widespread, and most areas around the world have sufficient sunshine hours, especially tropical and subtropical areas such as Africa and Australia.
• limit:Solar power generation is greatly affected by weather. For example, when it is cloudy, rainy or at night, the power generation efficiency will be significantly reduced. In addition, installing solar panels requires a large amount of space, and land use conflicts also need to be considered.

The geographical limitations of solar power generation are mainly reflected in latitude, climate and land resources. High latitude areas have shorter sunshine hours and lower solar power generation efficiency; and harsh climate conditions, such as areas with year-round rain or sandstorms, will also affect the power generation efficiency of solar panels. In addition, setting up large-scale solar power plants requires occupying a large amount of land, which may conflict with land uses such as agriculture and forestry.

wind energy

• Advantages:Wind energy is a renewable energy source and wind resources are abundant, especially in coastal, mountainous and plateau places, such as coastal areas in Europe, North America and China.
• limit:The stability of wind power generation is low because the magnitude and direction of wind force change over time, and a wind forecasting system needs to be established to improve the stability of power generation. In addition, the noise and visual impact of wind turbines can also cause environmental problems.

The geographical distribution of wind energy resources is uneven and is usually concentrated in coastal, mountainous and plateau places. For example, the North Sea and Mediterranean regions in Europe, as well as coastal areas in China, are rich in wind resources. However, the construction of wind power generation needs to consider factors such as wind conditions, terrain and environment. For example, it is necessary to avoid building wind turbines near bird migration routes and nature reserves.

hydroelectric power

• Advantages:Hydropower is a mature and reliable energy source with high power generation efficiency and a relatively stable power generation process.
• limit:Hydropower generation has relatively large geographical restrictions, requires sufficient water resources, and the terrain must be suitable for the construction of reservoirs and hydropower stations. In addition, hydropower may have an impact on the ecological environment. For example, reservoir construction will affect the natural flow pattern of rivers and the migration of fish.

The geographical limitations of hydropower are mainly reflected in the abundance of water resources and topographic conditions. Hydropower requires sufficient water resources and terrain suitable for the construction of reservoirs and hydropower stations. For example, rivers such as the Yangtze River and Yellow River in China, as well as rivers such as the Rhine River and Danube River in Europe, are important resources for hydropower generation.

In addition to the above-mentioned major green energy sources, there are also geothermal energy, tidal energy, etc. Geothermal energy is mainly concentrated in areas with frequent volcanic activity, while tidal energy requires a large tidal drop. The geographical limitations of these green energy sources also determine their potential for development and utilization.
