Applications of solar energy: 1. Use solar cells to convert the energy contained in sunlight into electrical energy by photoelectric conversion. 2. Use solar water heaters to use heat from the sun to heat water. to heat water and use hot water to produce electricity; 4. Use solar energy to desalinate sea water; Solar energy is a renewable energy source. It refers to the energy of thermal radiation from the sun and its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters.
Since the birth of life on earth, it has mainly relied on the energy of thermal radiation provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method. of prepairing food, such as making salt and drying salted fish. With the decline of fossil fuels, solar energy has become a significant part of human energy consumption and continues to grow. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Solar energy in a broad sense also includes wind energy, chemical energy, hydropower, etc. on earth.
Solar energy is generated by the fusion of hydrogen and helium inside the sun to release enormous nuclear energy. This is the energy of solar radiation. Most of the energy needed by humans comes directly or indirectly from the sun. Plants release oxygen, absorb carbon dioxide and convert solar energy into chemical energy and store it in the corps of the plant by photosynthesis. Fossil fuels such as coal, oil and natural gas are also primary energy sources formed by the evolution of ancient plants and animals buried underground over a long geological period. The energy contained in the earth itself generally refers to the energy related to the thermal energy inside the earth and the energy related to the nuclear reaction.
The energy linked to nuclear reactions is nuclear energy. When the structure of the atomic nucleus changes, it can release a large amount of energy, called nuclear energy, or nuclear energy for short, commonly known as atomic energy. It comes from nuclear fission energy resources when uranium, plutonium, etc. are produced. stored in the earth's crust undergo fission reactions, and nuclear fusion energy resources when deuterium, tritium, lithium, etc. stored in theocean undergo fusion reactions. These substances release energy when nuclear reactions occur. Currently, the main use of nuclear energy is electricity generation. In addition, it can also be used as other types of energy sources, heat sources, etc.
1. Solar water heater. A heater that converts solar energy into thermal energy and heats water from low temperature to high temperature to meet people's use of hot water in life and production. It is the most common and common application in life.
2. Solar dryer. Drying equipment that uses thermal energy from solar radiation to evaporate and remove moisture from wet materials.
This drying method has been widely used since ancient times to dry crops, seeds, fruits, fish, wood, etc. directly under thesun.
3. Solar seawater distiller. Also known as "solar evaporator" and "solar water purification device". It is a device that uses solar energy to purify waste water, desalinate sea water and crystallize salt water. Therefore, it is also called "solar seawater desalination device" and "solar salt crystallizer".
4. Solarium. Use solar energy to heat and cool your home. is a desirableIt is an energy efficient and environmentally friendly residence that generates heat, electricity and can also dehumidify, cool and ventilate.
5. Solar greenhouse. The sun's energy is used to increase the indoor temperature in the plastic greenhouse or glass room to meet the temperature requirements needed for plant growth. This is why people often call it an arti greenhouse.string.
