Renewable resources include two types: renewable resources and non renewable resources.

After human development and utilization, natural resources that cannot be regenerated for a considerable period of time are called non renewable resources. Mainly referring to various minerals, rocks, and fossil fuels in nature, such as peat, coal, oil, natural gas, metallic minerals, non-metallic minerals, etc. This type of resource was formed over a long geological period in a certain stage, region, and condition during the long-term evolution history of the Earth. Compared to the development of human society, its formation is very slow, and compared to other resources, its regeneration rate is slow or almost impossible. The development and utilization of non renewable resources by humans will only consume them, and it is impossible to maintain their original reserves or regenerate them.

Among them, some resources can be reused, such as metal resources such as gold, silver, copper, iron, lead, zinc, etc; Others are resources that cannot be reused, such as fossil fuels such as coal, oil, and natural gas. When burned as energy, although energy can be converted from one form to another, its original material form no longer exists and its form has undergone changes. The natural resources that can be regenerated and reused by humans through natural processes or artificial activities are called renewable resources, also known as renewable natural resources, such as soil, plants, animals, microorganisms, various natural biological communities, forests, grasslands, aquatic organisms, etc. Renewable natural resources can continue to regenerate, reproduce, and grow under specific spatiotemporal conditions in the current stage of nature, maintain or expand their reserves, and rely on seed sources for regeneration. Once the species source disappears, the resource cannot be regenerated, which requires scientific and reasonable utilization and protection of the species source in order to be able to regenerate, inexhaustible, and inexhaustible. Soil is a renewable resource because its fertility can be continuously updated through artificial measures and natural processes. But soil also has a non renewable aspect, because soil erosion and erosion can be much faster than the natural renewal process of regenerated soil, and become non renewable resources under certain time and conditions.

Renewable energy generally refers to various inexhaustible sources of energy, strictly speaking, it is an energy that will not be depleted in the lifetime of humanity. Renewable energy does not include currently limited energy sources such as fossil fuels and nuclear energy. Most renewable energy is actually the storage of solar energy. The meaning of renewable energy is not to provide energy for ten years, but for a hundred or even a thousand years. With the emergence of the energy crisis, people are beginning to realize the importance of renewable energy. Solar energy generally refers to the radiant energy of sunlight. There are two ways to utilize solar energy: passive utilization (photothermal conversion) and photoelectric conversion. Solar power generation is an emerging renewable energy utilization method. In a broad sense, solar energy is a source of many energies on Earth, such as wind energy, chemical energy, potential energy of water, and so on. The main methods of utilizing solar energy include: using solar cells to convert the energy contained in sunlight into electricity through photoelectric conversion, using solar water heaters to heat water using the heat of sunlight, and using hot water to generate electricity using solar energy for seawater desalination. Geothermal energy is natural thermal energy extracted from the Earth's crust, which comes from lava inside the Earth and exists in the form of heat, It is the energy that causes volcanic eruptions and earthquakes. The temperature inside the Earth can reach as high as 7000 degrees Celsius, and at depths of 80 to 100 kilometers, the temperature will drop to 650 to 1200 degrees Celsius. Through the flow of groundwater and the influx of lava to the Earth's crust 1 to 5 miles above the ground, heat can be transferred closer to the surface. The high-temperature lava heats the nearby groundwater, and the heated water will eventually seep out of the ground. The simple and cost-effective method of using geothermal energy is to directly extract these heat sources and extract their energy.
