Conditions and characteristics of non renewable energy sources

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, 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.

Non-renewable energy mainly includes coal, oil, and natural gas, which are formed by geological movement and sedimentation in a reducing environment for hundreds of millions of years, and need to have good trap conditions to be stored until now, and are generally distributed in sedimentary rocks. Coal is also formed in a reducing environment, by organisms buried by the movement of the earth's crust, after millions of years, which is shorter than the formation time of oil and gas, and the storage conditions are not very strict.

11. Non-renewable energy sources include: coal, natural gas, oil shale, and nuclear energy.

22. Renewable energy includes: solar energy, hydropower, wind power, biomass energy, wave energy, tidal energy, and ocean temperature difference energy.

33. Renewable energy: energy that can be continuously regenerated and replenished regularly in nature.

44. Non-renewable energy: energy that has been formed over hundreds of millions of years and cannot be restored in a short period of time.

Huge development potential, clean and pollution-free, most of them can be used in an environment, low development cost New energy in China currently refers to renewable energy and nuclear energy, I think it should be mentioned as follows: Compared with conventional energy, renewable energy has the following advantages: 1. The resources of renewable energy are greater than those of conventional energy, and conventional energy is average.

1. Non-renewable energy sources include: coal, natural gas, oil shale, and nuclear energy.

2. Renewable energy includes: solar hand rolling, hydropower, wind power, biomass energy, wave energy, tidal energy, and ocean temperature difference energy.

3. Renewable energy: energy that can be continuously regenerated in nature and regularly replenished.

4. Non-renewable energy: energy that has been formed over hundreds of millions of years and cannot be restored in a short period of time.

1. Non-renewable energy sources include: coal, natural gas, oil shale, and nuclear energy.

2. Energy that has been formed over hundreds of millions of years and cannot be restored in a short period of time is called non-renewable energy.

3. Such as coal, oil, natural gas, etc. With the large-scale exploitation and utilization, their reserves are getting smaller and smaller, and there will always be a time when they are exhausted. Geothermal energy is basically non-renewable, but it is renewable in nature due to the huge reserves in the earth's interior.

New developments in nuclear energy will allow the nuclear fuel cycle to have a multiplicative nature.

Non-renewable energy sources are the earth's stored resources such as coal, oil, natural gas, 、、、etc., which, once used, can no longer be generated. (These deposits were formed over a long period of time over hundreds of millions of years.)

Renewable energy is energy that can be used for a long time, such as wind, hydro, 、、、and solar energy, and is characterized by the fact that it can be used again and again, and is called renewable energy.

The common feature of these energy sources is that they may be converted into energy needed by people in production and life, such as electricity, heat, chemical energy, 、、、 for people to use.

I'm glad to answer for you, I hope it will be helpful to you, and I'm sorry to be annoying.

1. Non-renewable energy sources mainly include: coal, oil, natural gas, chemical energy, nuclear fuel, etc. It generally refers to the energy resources that cannot be regenerated at this stage after human development and utilization, and is called "non-renewable energy". Here are a few types of renewable energy.

2. Solar energy: The country that supports the use of solar energy the most in the world is Japan. In 2004, the production of Daiyo batteries in Japan reached 610 megawatts (originally the number of 2000, but the editor changed the statistics to 2004).

In the U.S., 15% of total electricity demand by 2020 will likely be covered by electricity produced by modern solar photovoltaic conversions.

3. Wind energy: In 2002, the installed capacity of wind power generation in EU countries increased by 33 to 23,056 megawatts, accounting for 70 of the world's total wind power generation. Wind power generation in Germany meets the country's electricity demand.

In 2002, Denmark relied on wind power to generate 13 percent of its electricity. They also plan to reach 50 by 2030. According to the American Institute of Energy, wind energy will guarantee 20 percent of the country's electricity needs.

By 2010, 10 million homes in the U.S. will be powered by wind power.

4. Geothermal energy: In 1999, the United States saved nearly 60 million barrels of oil by using geothermal power stations. In the same year, geothermal power generation reached 2,200 megawatts.

5. Bioenergy: On January 10, 2007, bioenergy guaranteed about 3% of the energy needs of the United States. The U.S. will produce 4 of motor fuel from biomass by 2010, 10 by 2020, and 20 by 2030.

In another 25 years, energy from biomass will cover more than 15 percent of the total energy needs of the United States. Biomass alcohol produced in the U.S. now guarantees the country's 2 automotive fuel needs. Europe is the world's largest producer of biodiesel.

In 2003, they produced 43 more biodiesel compared to 2001. By 2010, around 7% of Europe's fuels will be "green", i.e. from biomass.

Renewable energy does have many different characteristics and advantages and disadvantages compared to non-renewable energy. First of all, renewable energy sources such as wind energy, Tai or Tandong solar energy have relatively abundant reserves and will not be exhausted, and the energy generation method is relatively clean, and will not produce a large number of pollutants like non-renewable energy sources such as kerosene. At the same time, renewable energy is flexible and can adapt to different application scenarios, reducing dependence on traditional energy sources.

However, there are also some difficulties and shortcomings in renewable energy, such as high cost, large fluctuations in production capacity, instability and other problems, which need to be continuously studied and solved in technology, policy and market. In general, efforts are still needed to improve the level and efficiency of renewable energy applications, and to find a balance between renewable and non-renewable energy sources.
