Energy production methods and processes

The potential energy of the water drop in hydropower is converted into electrical energy by pushing the water turbine through the engine

The combustion of coal for thermal energy production produces high pressure steam to drive the steam turbine and engine and converts it into electrical energy

Nuclear fission in nuclear power plants generates thermal energy Heating generates high pressure steam pressure to drive steam turbines and generators to generate electrical energy

Wind power generation The circulating air acts on the rotation of the wind wheel (wind turbine) to convert the mechanical energy into electrical energy

Generation of solar energy using photovoltaic solar panels Convert solar energy into electrical energy

Generation of geothermal energy Thermal energy into energy electric

Tidal energy productionconverts mechanical energy into electrical energy via water turbines through diurnal tidal changes

Secondly, there is straw-based energy production, energy production by temperature difference of sea ​​water, etc.

How to judge kinetic energy and internal energy? Is hydroelectric generation kinetic energy or internal energy? How to judge

1. Water has a regulating effect on the climate.

2. Water is an important element of all living things. Water makes up 70% of the body weight of the human body; Water is an essential substance for maintaining life.

3. Substances necessary for daily life on the water. Such as cooking, laundry, bathing, cleaning, etc.

4. Industrial production cannot be separated from water. Such as raw material water, product processing water, boiler water, washing water, cooling waterement, etc.

5. Water conservation is the lifeblood of agriculture. Agricultural production requires a large amount of water for irrigation.

3/4 of the earth's surface is covered by water, but available fresh water represents only 2.53% of the world's total water storage, most of which is also distributed in polar glaciers and snow caps, mountain glaciers. and permafrost Difficult to exploit in layers. Kelley only uses about 30.4% of its water. In addition, with the rapid development of modern industry, large quantities of various wastewater are discharged, causing significant pollution of natural water systems, a general decline in water quality, and soft water of increasingly insufficient for safe use. Saving water, preventing water pollution and protecting water resources are currently important and fundamental national policies!

When the mass of an object does not change, its kinetic energy is related to the speed of movement. The greater the speed, the greater the kinetic energy while the internal energy of an object of the same mass is greater. is linked to temperature. Under normal circumstances, the temperature The higher it is, the greater the internal energy.

Hydroelectric power generation definitely uses the mechanical energy (kinetic energy and potential energy) of water to do work on the generator, operating the generator and thereby generating electrical energy . The energy transformation in this process is: mechanical energy of water → mechanical energy of generator → electrical energy.

In addition, once running water passes through the generator, its speed decreases, but its temperature practically does not change, so electrical energy is converted from mechanical energywater and not internal energy.
