Geothermal Energy ProductionGeothermal energy is thermal energy generated and stored in the Earth. Thermal power is the power that determines the temperature of matter. The geothermal energy of the Earth’s crust originates from the original formation of the planet and from radioactive decay of supplies (in currently uncertain 1 but possibly roughly equal two proportions). The geothermal gradient , which is the distinction in temperature among the core of the planet and its surface, drives a continuous conduction of thermal power in the type of heat from the core to the surface. The adjective geothermal originates from the Greek roots γη (ge), which means earth, and θερμος (thermos), meaning hot.

Geothermal is an unconventional renewable energy source to the extent that it is carried out in accordance with territorial and cultural requirements. The power supply in and of itself does not assure social and environmental sustainability,” land surveyor Lucio Cuenca, director of the Santiago-based Latin American Observatory on Environmental Conflicts , told IPS.

Geothermal fluids also include gases and minerals, though amounts vary from field to field, and the amount released depends on the style of energy station. So electricity generated from geothermal energy does create some greenhouse gas emissions. On the other hand, geothermal energy station emissions nevertheless make fewer greenhouse gas emission than the cleanest natural gas-fuelled energy stations.

Social acceptability of a geothermal project is the condition upon which the technical and economic objectives of the project could be pursued in due time, with the adhesion of the neighborhood communities obtained by acting in consonance with the dynamic situations of the environment and in the respect of the people’s overall health, welfare and culture.

Heat pumps are a way of converting a tiny amount of electrical energy into heat (or cooling). There is some controversy more than whether they ought to be classed as a renewable power supply, but they are normally classed as a low carbon power source. Normally although, the heat output can be classed as renewable if the electricity which is utilized to power it is renewable. Heat pumps can come in many types – ground supply heat pumps, water source heat pumps and air source heat pumps. The video above shows how a heat pump can be utilized to heat (and cool) a school along with examples.
