What are the cleaner energy sources in solar, wind, hydro, tidal, biomass, and geothermal energy

Judging from the current technical conditions, the cleanest are hydro energy and tidal energy, followed by solar energy and geothermal energy, and others are even more secondary.

Building a dam on a large river (the same is true for tidal energy, except that the dam becomes an underwater device) has no effect on the water, because the water downstream of the stream flows downward, and the water itself is the cleanest, so water and tides are the cleanest energy sources. As for the environmental impact of the construction of hydropower stations, it is not the hydropower station itself, but the mistakes of the relevant departments in planning and construction.

Solar energy is supposed to be the cleanest because the sun emits light without harmful substances. But the problem is that devices that convert light energy into electrical or thermal energy pollute the environment during the manufacturing process. For example, polysilicon refining will greatly pollute the environment.

The same is true for wind energy, which currently produces harmful substances from the devices that make use of it. Biomass energy also produces harmful gases during power generation.

The use of geothermal energy is to press water into the ground, which wastes water and is therefore not clean.

What do you mean?!

Solar, wind, hydro, tidal, biomass, and geothermal energy are all clean energy.

Nuclear energy is also included.

There is no such thing as cleaner!

Of course, the water is cleaner!

But the rest is also clean energy! ~

Summary. Biomass is unique in that it is stored solar energy and is the only renewable source of carbon that can be converted into conventional solid, liquid and gaseous fuels.

First, renewability. Biomass energy, wind energy, solar energy and other renewable energy are the same as renewable energy, which can realize the sustainable use of energy.

Second, clean and low-carbon. The content of harmful substances in biomass energy is very low, and it belongs to clean energy. At the same time, the conversion process of biomass energy is to synthesize carbon dioxide and water into biomass through the photosynthesis of green plants, and the use of biomass energy generates carbon dioxide and water to form a circular emission process of carbon dioxide, which can effectively reduce the net emission of human carbon dioxide and reduce the greenhouse effect.

Third, substitution advantages. The use of modern technology can convert biomass energy into biomass pellet fuel, biomass combustible gas, biomass liquid fuel, etc., which can replace fossil fuels. It can be used in most industrial boilers and kilns that use oil, coal and natural gas.

Compared with traditional energy sources, wind, solar, and biomass have common advantages.

At the same time, the conversion process of biomass energy is to synthesize carbon dioxide and water into biomass through the photosynthesis of green plants, and the use of biomass energy generates carbon dioxide and water, forming a circular emission of carbon dioxide buried in the dioxygen Qingju process, which can effectively reduce the net emission of human carbon dioxide and reduce the greenhouse effect.

Thank you. You're welcome dear.

4.Solar energy, hydro energy, marine energy, wind energy, tidal energy, and energy return energy belong to renewable energy.

a.That's right. b.Mistake.

Correct Answer: a

a nuclear, solar, geothermal) town and is a liquid travel orange clean energy.

Clean energy, that is, green energy, refers to energy that does not emit pollutants and can be directly used in production and life, it includes nuclear energy and "renewable energy". Bioenergy in B and C is not a clean energy source, and bioenergy in bioenergy will emit pollutants during the combustion of biofuels (bioethanol, biobutanol, biodiesel, biomethanol, etc.).

Summary. Dear, hello teacher is very happy to answer for you, the most important feature I found here is that new energy will not produce carbon emissions while getting energy. It is well known that carbon dioxide produced through combustion is a greenhouse gas that can wreak havoc on the natural environment.

If we replace fossil fuels with new energy sources on a large scale, we can reduce carbon dioxide emissions and thus reduce the worsening of the greenhouse effect.

Dear, hello teacher is very happy to answer for you, the most important feature I found here is that new energy will not produce carbon emissions while getting energy. As we all know, the carbon dioxide produced by the indiscriminate combustion of the source is a greenhouse gas in the form, which will cause serious damage to the natural environment hail. If we replace fossil fuels with new energy sources on a large scale, we can reduce carbon dioxide emissions and thus reduce the worsening of the greenhouse effect.

Nuclear energy is a clean energy source, which generally does not cause harm to the environment, and the dry radioactive materials are also very safe, which can replace fuel power generation, reduce carbon dioxide emissions, and reduce the consumption of traditional energy. The utilization of solar energy mainly includes heating and cooling, solar thermal power generation, and solar power generation, and solar energy can be directly used without pollution. New energy sources such as marine energy, wind energy, geothermal energy, combustible ice, and hydrogen energy will not produce environmental pollution, and are clean energy, which is expected to replace traditional energy more extensively.

Give you a reference kiss.

I hope mine can help you.

Well. You're welcome to kiss.

Summary. Bioenergy has the following advantages: (1) it provides low-sulfur fuel, 2) it provides cheap energy (under certain conditions), 3) it reduces environmental hazards by converting organic matter into fuel (e.g., waste fuel), and 4) it has fewer technical challenges than other non-traditional energy sources.

Compared with traditional energy sources, wind, solar, and biomass have common advantages.

BioenergyBioenergy is a form of energy stored in organisms in the form of chemical energy, a kind of energy with biomass as the carrier of Bijizhi, which directly or indirectly ** the photosynthesis of plants, in a variety of renewable energy, biomass is unique, it is the stored solar energy, but also a only renewable carbon source, which can be converted into conventional solid-state hand-sensitive, liquid and gas-front rock fuel. All biomass has a certain amount of energy, and the main energy used as energy is the by-products of agriculture and forestry and their processing residues, but also includes human and animal manure and organic waste. Biomass energy provides the basic fuel for humans.

Summary. First: it is the most abundant energy available to human beings, and it is really inexhaustible.

Second: no matter where there is on the earth, it can be developed and utilized on the spot, and there is no transportation problem, especially for rural areas, islands and remote areas where transportation is underdeveloped. Third:

It is a clean energy source. In the development and utilization, there will be no waste residue, waste water, waste gas, no noise, and no ecological balance. Absolutely no pollution and pollution shortcomings:

Clause. 1. Traditional energy can be adjusted according to needs**, solar wind energy is intermittent and cannot be controlled as needed, solar energy is only available during the day and sunny days, and the size of the wind stove often changes uncontrollably. To make effective use of solar and wind energy, energy storage is a must.

Clause. Second, the energy density is low, and when it is used on a large scale, it is purely necessary to occupy a large area of land; Clause.

3. At present, it is still relatively expensive, 3 15 times that of conventional power generation, and the initial investment is high.
