Rejection of pollution, support for renewable energy

Renewable Energy is energy from nature, such as solar energy, wind power, tidal energy, geothermal energy, etc. It is an inexhaustible source of energy. It is a relatively non-renewable energy source that will be exhausted. Energy sources.

Water energy

Hydroelectric power is mainly used for hydroelectric power generation.

The advantages of hydropower: no pollutant emissions, on-demand power supply, stable electricity prices, low operating costs, can help control floods, can be used to prepare irrigation water, improve river navigation and so on.

The adverse effects of hydropower: permanent ecological damage and land loss, downstream soil erosion, reduced irrigation water use, impediments to the migration of aquatic organisms, and reduction in the number and species of fish stocks.

2. Ocean energy

Including tidal energy, wave energy, current energy, temperature difference energy, and salt difference energy.

Advantages of ocean energy: Because of its potential for cleaning, it has less potential impact on the environment and it has potential for long-term carbon reduction.

Ocean energy use restrictions: Because it is in an early stage of development, it is unlikely to make a significant contribution in the short term.

3. Solar energy

Solar energy is widely used. Here we introduce solar photovoltaic power generation.

Photovoltaic power is low-carbon and environmental-friendly. After calculation, the installation of a photovoltaic power generation system of 1 square meter can reduce the use of 400 kilograms of standard coal, thereby reducing 1 ton of carbon dioxide, which is equivalent to 100 square meters of afforestation.

4. Wind energy

The potential of wind energy utilization is very large, clean and less polluting.

Wind power generation is the use of wind to drive the wind turbine blades to rotate, and then through the speed increaser to increase the speed of rotation, to promote the generator to generate electricity. The amount of wind energy reserves on the earth is very abundant. The energy that the world uses to burn coal every year is only 1/3 of the energy provided by wind within one year, and its power generation cost is closest to conventional energy.
