Hydroelectricity is an Efficient Way to Power the World

Abstract As human beings need more energy in daily life in modern society, renewable energy sources such as fossil fuels are rapidly depleted and renewable energy is getting more and more popular. For example, many energy sources are used around the world such as wind power, sunlight, hydraulic power and so on. Among them, the use of hydropower, running water, renewable energy sources is an efficient and economical alternative to pollution instead of fossil fuels, and it is possible that they will make up the majority of the world's energy in the future.

Regarding renewable energy, hydroelectric power generation is OG. The first hydroelectric power plant started operations in Wisconsin in 1882 and produced about 12.5 kilowatts of electricity. Since then, hydroelectric power has made great progress. In 2014, 17% of the world's electricity generation was due to hydroelectric power generation. This is a problem. For a long time, Brazil has relied on Amazon's huge resources to generate electricity. Currently, over 70% of the country's electricity is generated by hydroelectric power generation. As a result, the proportion of Brazilian electricity sector to carbon emissions is very low. However, reliance on this hydroelectric power generation causes various problems. The government must force local indigenous people resettled. In addition, excessive dam construction can disturb the natural flow of the river. This affects the ecosystem supported by the river.

Today, kinetic energy of a flowing river is captured and converted into hydroelectric power in a completely different way. The most well known type of hydroelectric power generation is created by a system that is configured to store water in a reservoir where the dam flows through the turbine when the reservoir is released. Ocean thermal energy can be converted to electrical energy through several different systems depending on warm surface water temperature. "Ocean mechanics energy" utilizes tidal fluctuations caused by the rotation of the earth and the influence of the gravity of the moon. You can also convert the energy from the wind waves and help reduce the electricity bill
