Are vegetable fuels a renewable energy source?

Vegetable fuels are not renewable energy, because renewable energy can be recycled in nature, is an inexhaustible source of energy, and will automatically regenerate without human participation, which is a kind of energy relative to the non-renewable energy that will be exhausted; However, plant fuels are not renewable when used.

Renewable energy includes solar energy, hydro energy, wind energy, biomass energy, wave energy, tidal energy, ocean temperature difference energy, geothermal energy, etc. Some countries are starting to think about "100% renewable energy policies", because renewables have long been considered to be at best a supplement to energy sources such as fossils or nuclear power.

Plant fuels should be classified as renewable energy sources.

Natural resources that can be regenerated and renewed through natural actions or artificial activities, and are repeatedly used by human beings are called renewable resources, also known as non-depleting 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 under the specific spatio-temporal conditions of nature at this stage, and rely on the provenance to regenerate. 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. But there is a non-renewable aspect to soil, 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.

Non-renewable. There are many types of plants that can be used as energy, mainly certain crops and organic residues, forest trees, forest industry residues, algae, and aquatic plants are also energy plants to be developed. Plants are used as an energy source, either as a solid fuel, or scientifically converted to carbon, combustible or bio**, among others.

In terms of forestry energy, the cultivation of trees with fast growth, high photosynthesis efficiency and strong fecundity has been paid attention to abroad. The Chinese Academy of Forestry has conducted an experimental study and listed more than 60 kinds of energy plants. There are two ways to use forest energy:

extraction of gas, tar and charcoal by dry distillation; Direct combustion, oil plants are also a new field that has opened up in recent years. Oil is a non-renewable energy source, so its depletion is inevitable and inevitable. Therefore, many countries are conducting research on alternative energy, and the research on energy plants came into being.

Professor Carr, a Nobel laureate in the United States, developed the first artificial oil plant as early as 1984, with a harvest of 120-140 barrels per hectare. Millions of acres of oil plants are now grown in the United States, 1.5 million acres in the United Kingdom, and Switzerland has plans to replace half of the country's oil consumption with vegetable oil.

It is a renewable resource, because the energy of plants is from solar energy, not from the land, because of photosynthesis, plants can grow repeatedly so they can be renewable, such as using corn and sugarcane to make alcohol fuel, rotting plants to produce biogas, using straw to make briquettes, 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.

Fossil fuels are non-renewable energy sources.

Fossil fuels are coal, oil, natural gas, and other non-renewable fuel resources that are buried underground and under the ocean. Fossil fuels are classified into coal, oil, oil shale, natural gas, oil sands, and combustible ice under the sea in order of the amount of energy buried.

As suggested by the conceptual principles of supply and demand, when fossil fuels fall, they rise. Therefore, when fossil fuels** are high, there will be more energy selectivity, and renewable energy, which was generally considered uneconomical, will become one of the more economically viable energy sources.

At present, although the cost and processing technology of artificial gasoline and other renewable energy sources are higher and more complex than ordinary oil production, the economic benefits in the future will be higher than that of ordinary oil production.

Renewable energy refers to non-fossil energy sources such as wind, solar, hydro, biomass, and geothermal, which are clean energy.

It is a green and low-carbon energy source and an important part of China's multi-wheel drive energy system, which is of great significance for improving the energy structure, protecting the ecological environment, responding to climate change, and achieving sustainable economic and social development.

In 2020, China's renewable energy generation reached 2,214.8 billion kWh, a year-on-year increase. By the end of 2020, China's installed renewable energy generation capacity reached 100 million kilowatts, a year-on-year increase of about 100 million.

It is clearly proposed that China's carbon dioxide emissions will peak before 2030, strive to achieve carbon neutrality before 2060, and by 2030, the proportion of non-fossil energy in primary energy consumption will reach about 25, and the capacity of wind and solar power generation will reach more than 1.2 billion kilowatts, which further points out the strategic direction of China's energy transformation and reform, and sets a new beacon for China's renewable energy development.

The value of renewable energy:

Practice has proved that renewable energy can not only provide clean alternative energy, but more importantly, it can promote the development of equipment manufacturing and other related industries, which is an effective way to accelerate the transformation of economic development mode and economic restructuring in the post-international financial crisis period.

The development and utilization of renewable energy is of great significance to ensure energy security, protect the ecological environment and achieve sustainable development. It is necessary to take the development of renewable energy as a strategic measure to re-emphasize the loss of money, and earnestly grasp it.

At the same time, China actively promotes the clean utilization of biomass energy such as urban and rural organic waste, and promotes the improvement of human settlements. Actively explore the photovoltaic desertification control model that combines desert management, photovoltaic power generation, and planting and breeding, promote the combination of photovoltaic development and ecological restoration, and realize the coordinated development and complementarity of renewable energy development and ecological civilization construction.

Be. Renewable resources are natural resources that can maintain or increase their reserves at a certain rate of growth through natural forces. For renewable resources, the sustainable utilization of resources is mainly achieved through reasonable regulation and control of resource utilization.

The sustainable use of renewable resources is mainly constrained by the law of natural growth. Renewable resources (crops, forests, seafood processing waste, etc., collectively referred to as raw materials) from animals and plants in nature are inexhaustible resources. <

Coal, oil, natural gas, chemical energy, nuclear fuel.

Energy sources that have been formed over hundreds of millions of years and cannot be restored in the short term are called non-renewable energy sources. 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.

Most non-renewable energy sources are fossil fuels: coal, oil, and gas. Carbon is the main element in fossil fuels.

Therefore, the time period for the formation of fossil fuels is called the Carboniferous period, which is about 100 million years ago. All fossil fuels were formed in a similar way, hundreds of millions of years ago, even before the dinosaurs appeared, and the ground wheel ball had a different landscape. It is covered by wide, shallow sea and swampy forests where plants, algae, and plankton grow on these ancient and sharp wetlands.

They absorb sunlight and produce energy through photosynthesis. When they die, the silver model tells them to drift to the bottom of the ocean or lake. Plants and animals have energy reserves after death.
