Is electricity a renewable energy source? Is electricity a renewable energy source

Thermal power in electricity is not a renewable energy source, hydropower, nuclear power, solar wind power generation are renewable energy sources. After human development and utilization, energy resources that cannot be regenerated at this stage are called "non-renewable energy". For example, coal and oil are the remains of paleontology that are buried in the deep underground and formed after a long geological time (so they are also called "fossil fuels"), and once they are burned and consumed, they cannot be regenerated in hundreds or even tens of thousands of years, so they are classified as "non-renewable energy".

Renewable energy.

It generally refers to non-fossil energy sources obtained from nature and can be renewable, and currently mainly refers to natural energy sources such as wind, solar, hydro, biomass, geothermal and ocean energy. China's renewable energy resources are very abundant, and there is great potential for development and utilization.

The book says: Like electrical energy, it cannot be obtained directly from nature, and it needs to be consumed to obtain it, and such energy is called secondary energy. Fossil energy and nuclear energy will be used less and less, and cannot be replenished in the short term, they are non-renewable energy.

The kinetic energy of water, wind energy, solar energy, and biomass energy, which can be continuously obtained in nature, is called renewable energy. Through analysis, we know that electricity cannot be obtained continuously from nature, so electricity is not a renewable energy source. But will the electricity be used less and less?

Electricity can be obtained through water and wind energy, and it will not be used less and less. So electricity is not non-renewable energy. Therefore, electric energy can only be said to be secondary energy, not renewable.

No. After human development and utilization, natural resources that cannot be regenerated for a long time are called non-renewable resources. It mainly refers to various minerals, rocks and fossil fuels in nature, such as peat, coal, oil, natural gas, metal minerals, non-metallic minerals, etc.

This kind of resource is formed in the long-term evolution history of the earth, in a certain stage, in a certain area, under certain conditions, through a long geological period. Compared with the development of human society, its formation is very slow, and compared with other resources, the rate of regeneration is very slow, or almost non-renewable. Human beings will only consume non-renewable resources, and it is impossible to maintain their original reserves or regenerate.

Among them, some resources can be reused, such as gold, silver, copper, iron, lead, zinc and other metal resources; Others are resources that cannot be reused, such as fossil fuels such as coal, oil, and natural gas, and when they are burned as energy sources, although the energy can be converted from one form to another, the original material form no longer exists, and its form has changed.

Natural resources that can be regenerated through natural actions or artificial activities, and are repeatedly used by human beings are called renewable resources, also known as renewable natural resources, such as soil, plants, animals, microorganisms and various natural biological communities, forests, grasslands, aquatic organisms, etc.

Renewable natural resources can continue to regenerate, reproduce and grow, maintain or expand their reserves, and rely on seed sources to regenerate under the specific spatio-temporal conditions of nature at this stage.

Once the provenance disappears, the resource cannot be regenerated, so it is necessary to scientifically rationally use and protect the provenance of the species, so that it can be regenerated and "inexhaustible". Soil is a renewable resource because soil fertility can be continuously renewed through artificial measures and natural processes. However, soil has a non-renewable aspect, because soil erosion and soil erosion can be much faster than the natural regeneration process of regenerated soil, and it will become a non-renewable resource at a certain time and under certain conditions.

Renewable energy refers to a variety of inexhaustible energy sources, and strictly speaking, it is an energy source that will not be exhausted in the lifetime of human beings. Renewable energy does not include energy sources that are currently limited, such as fossil fuels and nuclear energy.

Most of the renewable energy is actually the storage of solar energy. Renewable does not mean 10 years of energy, but 100 years or even 1,000 years.

Fuels such as oil and gas are non-renewable.

Water, solar energy, wind, etc. are renewable.

Electrical energy is, of course, also renewable.

Renewable is something that can be formed naturally, and non-renewable is something that needs to be processed by people to form what we need.

1. Electric energy is not a renewable energy source, and electric energy is a secondary energy source. Primary energy can be further divided into two types: renewable energy and non-renewable energy. Renewable energy includes solar energy, hydro energy, wind energy, biomass energy, wave energy, tidal energy, ocean temperature difference energy, geothermal energy, etc.

They can be recycled in nature. It is an inexhaustible source of energy that will automatically regenerate without human involvement, and is a kind of energy relative to the non-renewable energy that will be exhausted.

2. The electrical energy used in daily life mainly comes from the conversion of other forms of energy, including water energy (hydroelectric power), thermal energy (thermal power generation), atomic energy (nuclear power), wind energy (wind power generation), chemical energy (batteries) and light energy (photovoltaic cells, solar cells, etc.).

Renewable energy (English: renewableenergy) refers to wind energy, solar energy, hydro energy, biomass energy, geothermal energy, marine energy and other non-fossil energy, is an inexhaustible energy, is relative to the exhaustion of non-renewable energy energy, harmless to the environment or minimal harm, and the resources are widely distributed, suitable for local development and utilization.

The main reasons for the use of renewable energy by humans are as follows.

1. The progress of science and technology has made this kind of energy more "easy to use".

2. Fossil energy is limited, not only will it increase day by day, but it will eventually be exhausted.

3. Some renewable energy sources (e.g., wind, hydro, solar) do not emit greenhouse gases (e.g., carbon dioxide) and therefore do not increase the risk of the greenhouse effect.

4. In order to improve energy security, reduce dependence on imported fossil energy, and meet the demand for sustainable energy.

This starts with the origin of electricity

The electricity we use in our lives is generated from power plants through power generation turbines, which need to consume other energy to rotate. It is already obvious that electrical energy is converted from other forms of energy and belongs to secondary energy.

We often talk about renewable energy as energy sources that can be repeated over a long period of time**. Electricity is our direct application energy, and it doesn't make sense to say it's non-renewable.

In the past, coal, gas, and oil are all non-renewable energy, because it is produced by hundreds of millions of years of earth's evolution, and we can't wait for hundreds of millions of years in the application of petroleum coal, that is, the generation cycle of other doors is relatively long, and people can't afford to wait.

But for hydropower, wind power, solar power, these things can be reused, such as hydropower: as long as there is atmospheric flow, there is an air flow, the air flow brings the water vapor evaporated from the ocean to the high-altitude mountain plateau, and then forms rainfall, and the rainwater is collected into a river and flows back to the ocean, in this process, the water is too high by the evaporation of the sun, and it also has potential energy correspondingly. The same is true for wind energy, which is a form of solar energy conversion.

Solar panels, on the other hand, are made by directly converting sunlight radiation into electrical energy, using the photovoltaic effect of semiconductor materials, and the conversion rate at this stage is lower (energy conversion green is more than 10%, less than 17) and the equipment cost is higher.

It would be incorrect to say that electricity is a renewable energy source, and it is not in the category of renewable non-renewable energy in itself.
