Which indirect form of energy is wind and hydro? Electricity or solar energy

Solar energy causes the air to produce heat and temperature differences, and only when there is a temperature difference will the air produce the difference in air pressure, and only when there is a difference in air pressure will the air flow will be generated, that is, wind energy.

The potential energy of water comes from the difference in topography or tidal force, and the difference in terrain comes from the internal energy of the earth, that is, the internal movement of the earth produces the difference in topography, the movement of the earth's crust should have been learned in geography, I will not explain it, and the energy of the earth's internal movement is from the internal energy of the earth, the internal energy of the earth comes from the radiation of the sun, and the tidal force also comes from the gravitational force of the sun.

Let me summarize again, most of the energy on the earth comes from the sun in the final analysis, such as the electric energy you said, there are two ways of common electric energy**, thermal power, hydroelectric power, thermal power is to use coal and other fuels to generate electricity, but coal ** is the ancient plant, the energy of plants is obtained from the sun through photosynthesis, and the water power has been explained above is from the sun.

Of course, there are some that do not come from solar energy, such as nuclear power, which comes from the decay and fission of radioactive elements.

Wind and hydro energy are indirect forms of solar energy. The sun is going on.

Nuclear fusion reactions.

A steady stream of energy is radiated outward, and strictly speaking, all energy on the earth comes from sunlight.

By definition, energy is the ability of an object to do work. Only when an object has energy can it do external work.

There are many forms of energy, such as: mechanical energy, internal energy, electrical energy, nuclear energy, and so on. Different forms of energy can also be converted into each other and can also be transferred from one object to another.

Solar energy conversion forms include electricity, heat, wind, and bioenergy.

Wait. Solar energy is a kind of renewable energy, which is generally used to generate electricity or provide energy for water heaters in modern times, and there are two ways: photothermal conversion and photoelectric conversion.

Solar energy is made up of hydrogen atoms inside the sun.

Hydrogen-helium fusion releases a huge amount of nuclear energy, resulting in radiant energy from the sun. Fossil fuels such as coal, oil, and natural gas are also primary energy sources that evolved over a long geological period from plants and animals buried in the ground in ancient times.

Wind energy is a form of conversion of solar energy.

Due to the different changes in air temperature and the different content of water vapor in the air after being irradiated by the sun, the air pressure varies in various places, and the high-pressure air flows to the low-pressure area in the horizontal direction, that is, the wind is formed. That is, there is no wind energy without the sun. Therefore, wind energy is a form of solar energy.

The development and utilization of wind energy has been highly valued by countries around the world. China's wind energy reserves are large and widely distributed, and the potential for development and utilization is huge. At present, China's wind power industry has achieved rapid development, but there are also many problems in the process of rapid development.

Therefore, in order to vigorously develop China's wind power generation industry, it is necessary to increase self-reliance and innovation, increase construction investment, increase support, and establish a complete and unified wind power standard and specification system.

It can be said that it is all new energy.

Of course it belongs. Primary energy is the energy obtained from nature and used directly without change or transformation. Wind, solar, and hydro energy are all clearly obtained from nature and remain unaltered.

Primary energy sources generally include raw coal, natural gas, hydropower, wind energy, solar energy, marine energy, tidal energy, geothermal energy, natural uranium ore, etc.

It belongs to primary energy, and they can be used directly. As long as the energy is not converted and converted, it belongs to primary energy.

Item B, item A Coal is the organic matter generated by plants after absorbing sunlight for photosynthesis, which is formed after hundreds of millions of years of cultivation in the ground, so it can be regarded as storing light energy in coal Item C Wind energy is due to the sun irradiating the earth, making the heat uneven, causing air flow, so wind energy can be regarded as the indirect generation of solar energy Item D Water energy involves the water cycle in nature, and it is the heat brought by sunlight that evaporates the water and ensures the operation of the water cycle, so solar energy is the driving force to maintain this cycle.

Wind energy: Due to the difference in pressure in different areas due to factors such as atmospheric temperature, air flows from the high-pressure area to the low-pressure area, forming wind. It is replaced with mechanical or electrical energy by the fan.

Hydro energy: The potential energy formed due to the different heights of the water surface is converted into mechanical or electrical energy by the water turbine.

Thermal energy: Caused by the movement or vibration of a large number of molecules inside the substance, it is related to the sensitive temperature. General thermal energy conversion to mechanical energy requires:

Working fluid, high-temperature heat source, low-temperature heat source, conversion equipment, commonly used internal combustion engines, steam turbines, gas turbines, etc., commonly used cycles: Rankine cycle, Carnot cycle.

Chemical energy: The release of energy through the occurrence of chemical reactions: combustion is the most common and widely used, such as the leakage combustion of coal and oil. There are two common types of conversions: the replacement of galvanic cells into electrical energy, the generation of heat energy through combustion, and the conversion of mechanical energy through heat engines.

Solar energy: The photoelectric effect produces an electric current that irradiates an object to produce heat energy (radiative heat transfer).

Kinetic energy: the energy generated by the macroscopic motion of a mass object or the energy bridge of the motion of tiny particles, the former is mechanical energy, and the latter is the cause of thermal energy. A high-quality form of energy that can be completely converted into any other form of energy.

Mechanical energy: The sum of kinetic and potential energy. The highest quality energy form that can be completely converted into any other form of energy.
