What is heat energy

Heat, or thermal, energy is energy that is harnessed from most often the Earth or the sun in geo or solar forms, respectively. Most often the term “heat energy” refers to geothermal energy that is generated at power plants throughout the world and also used in its natural form to assist with heat dispersion in buildings as well as natural water heating for residential, commercial or recreational use.

Geothermal power production specifically refers to the harnessing of the heat of the Earth in order to produce power by drilling through the crust at select geographic hot-spots where the Earth’s crust is thinner than usual and pumping water into the created hole in order to generate steam that can then be used to power turbines for energy production on the surface. This can produce clean energy at a highly stable and efficient rate with little or no negative impact upon the surrounding environment but only be done at a select few locations worldwide at this time due to the requirements of being able to generate enough heat feasibly at selects thin crust locations that are commonly found near fault lines or young volcanoes.

Natural forms of heat energy can also be found in the form of hot springs located worldwide and used often as spas or applied for domestic use as even the heating systems for some buildings. Some places such as Iceland regularly use natural forms of geothermal heat in order to provide hot water for the population as well as generate electricity and pre-heat homes during cold months. Many structures around the world also use heat dispersion systems to tap into the constant temperature that exists a few feet below the earth’s surface and their pre-heat or pre-cool both the air and structure of buildings to cut back on standard energy costs that are common to summer and winter months.

Solar heat energy refers to not the process of collecting and producing energy with solar cells but of channeling the thermal rays generated by the sun into a single location to superheat a spots and using the generated heat to produce power. In many ways this is similar to the way geothermal power plants operate in that solar thermal energy most often utilizes steam power to generate electricity through turbines however the source of heat used for power generation is different and not necessarily as stable. Given the size of the area needed to feasibly produce energy in this form these forms of energy production are not very common nor necessarily as reliable as geothermal power plants as they cannot maintain a constant energy output if they do not have direct access to the sun on a regular basis. They are useful, however, in pre-heating the water supplies of millions of homes worldwide by being able to naturally warm water in colder temperatures and save on energy that would otherwise be expended in generating the heat necessary to produce hot water. Generally, this form of heating uses a combination of solar power energy collection through solar cells as well as solar thermal energy retention.
