What are the basic energy to the survival of humans

Renewable energy is a self restored the original features, and the sustainable utilization of energy at a time. Including solar energy, Can be used for solar street lamps, etc. ) , hydropower, biomass energy, hydrogen energy, wind energy, wave energy, and the thermal cycle between the sea surface and deep.

all human activity is the basic energy from the sun, being absorbed through photosynthesis in plants.

wood, wood is the earliest use of energy, through the burning into heat energy. Wood in cooking and provide heat is very important, it lets people can still survive in the cold environment.

hydraulic: hydroelectric power is an important energy in modern, especially countries like China is full of rivers. In addition, China has a long coastline, also is appropriate for tidal power.

wind: the principle of power generation is using wind power to drive the windmill blades rotating, again through the growth machine will increase the speed of rotation, to make generator to produce electricity. On the basis of the current versions of the windmill, the wind speed is about three meters per second ( The degree of the breeze) , you can begin to generate electricity.

affects animals: traditional farm animals such as cows, horses and mules in addition to the transport of goods, also can pull grinding, pushing some machinery to produce energy.

biomass fuels: originally the fuel renewable energy, such as balancing can output and consumption does not increase carbon dioxide. But if consume excessive deforestation and depletion can be returned to the soil organic matter, will destroy the production consumption balance. Using biomass to produce biogas for cooking lighting in the pool, residue but also a good organic fertilizer. Methanol can be used as a vehicle fuel ethanol from biomass.

the development of human society depends on the occurrence of high quality energy and the use of advanced energy technologies. In today's world, the development of energy, energy and environment, is the whole world, all issues of common concern, is also an important problem in the social and economic development of our country. 【 The above content released by LED solar street light for you finishing 】
