Heat energy is the name given to the energy transferred to increase the temperature of a substance. It occurs by heat transfer from a substance with a higher temperature to a substance with a lower temperature.
Heat energy, which is also known as thermal energy, is beneficial for our lives. It can, for example, be used to warm our houses or cook our food. There are four main sources of heat energy which are solar energy, geothermal energy, biomass, and fossil fuels.
Solar energy is a clean energy source produced from direct sunlight, without any harmful gas emissions. Most of this energy consists of hydrogen. For this reason, it is known as the cleanest renewable energy source in the world. The heat energies released during the conversion of hydrogen in the sun to helium are called solar energy.
Geothermal resource, briefly, is ground heat, and hot water, steam, and gases containing chemicals, formed by the heat accumulated in various depths of the earth’s crust.
Geothermal energy, on the other hand, includes any direct or indirect benefit from geothermal resources. Geothermal energy is a new, renewable, sustainable, inexhaustible, cheap, reliable, environmentally friendly, domestic, and green energy type.
As a sustainable and renewable energy source, biomass energy is a type of energy obtained by burning organic materials. Especially crop residues, forest products, aquatic plants, as well as commercial or domestic wastes can be used as fuel for the operation of this system. Even the garbage generated during the day can be used as fuel in order to obtain biomass energy.
Fossil fuels are energy sources that are composed of animals and plants that remain under rocks and soil for millions of years and fossilize under heat and pressure. The most important feature of fossil fuels is that they consist of organic materials with high hydrocarbon and carbon content.
Fossil fuels are formed by the thermochemical reactions of plant and animal remains buried under the ground millions of years ago in a particular region. In other words, fossil fuels are formed in certain regions and their amounts are limited.
