Green energy refers to sources of energy that are in harmony with their environment and the process of their production does not cause environmental pollution. Currently, energy from wind, solar, internal heat of the earth and running water are known as the most famous sources (green energy). Also, according to some experts (nuclear energy) can be considered by considering such as green energy. The use of the word green alongside the above energy sources is due to the fact that these sources do not produce carbon dioxide like plants.

Traditionally, electricity generation from the above sources is the most common type (green energy). Today, green energy is not just about environmental considerations. In fact, most governments pursue the issue of green energy economically.

In other words, green energy, because it is (renewable), eliminates the need for governments to run out of fossil fuel resources. There are other green energies that can be used on a smaller, local scale. For example, scientists use the force of tides, the force of waves on shores, the force of natural waterfalls, or even the heat of anaerobic decomposition of bacteria. Scientists use green tech education for solving all environmental problems that can harm world.

Solar energy

Solar energy is the most unique source of renewable energy in the world and is the main source of all energy on earth. Solar energy can be directly and indirectly converted into other forms of energy. In general, the energy emitted by the sun is about 1.3 x 1018 joules per second.

Geothermal energy

Geothermal energy comes from heat from the decomposition of radioactive materials, the Earth’s molten core, orogeny, and intra-Earth reactions. Almost everywhere, in shallow parts of the earth or 10 feet above the ground, the temperature remains almost uniform and is between 50 and 60 degrees Fahrenheit (10 to 16 degrees Celsius).

Hot springs are examples of geothermal energy, where water is heated by underground rocks and then flows to the surface. About twenty countries use this energy to heat homes, water or generate electricity. At present, the overall efficiency of this system is less than one percent of the world’s energy needs.

Biomass energy

This energy is supplied from plant or animal sources. Using special technologies, this type of energy can be converted into heat. Biomass energy is currently the fourth largest source of energy in the world.
Various types of energy, solid and gaseous fuels, heat, chemicals and other materials can be obtained from bioenergy technologies from renewable plant-animal sources. Research and development of technologies of this type of fuel is done in three main areas: fuel production, finding its applications, creating suitable infrastructure for biomass distribution, is the fourth largest energy source in the world and provides about 14% of the world’s energy .

Biomass, or biomass, is a term used to describe a series of products derived from the process of photosynthesis. A very common economic use of biomass energy is to use items that have been collected for other purposes, such as agricultural waste, food, and municipal waste.
