Is geothermal energy renewable or inexhaustible?
yes geothermal energy is renewable!
Geothermal is considered a renewable resource as it uses water and the earth's heat. Both of these are inexhaustible. However, if the water near the plant is exhausted (no more water in that area, but there is no less water than before), then the plant must be moved. It is still generally considered a renewable source of energy.
Geothermal energy is derived from heat within the Earth. Most of that heat is the result of radioactive decay of elements in the minerals that make up the core of the planet. While geothermal energy is technically not a renewable resource (over billions of years, the Earth's core will inevitably cool), the amount of energy is so enormous that it is, for all practical purposes, inexhaustible.
Wind energy, solar energy gravitational energy and geothermal energy resources will remain inexhaustible. There is enormous amount of energy created by the thundering clouds, which we have to harness in future. Nanotechnology is also paving the way to unfold the mystery of photolysis of water by chloroplasts in the plant cells, if it could be done in the laboratory we will be opening a Pandora of unlimited resource of energy.
Sources of energy which are not renewable are those that use up a substance to create the energy. These include fossil fuel energy (oil, gas and coal) and atomic energy (uranium and thorium). Sources of energy which are renewable are resources such as wood or other plant derived fuels. Generally included in this heading are those energy sources which are inexhaustible such as water power in its many forms, solar power, geothermal energy, and wind…
Energy sources can be split into three categories: * Non-renewable: The source is limited (coal, gas, oil etc.) and once gone cannot be replaces * Renewable: The source replicates itself by organic growth or natural processes (Plant matter, wind or wave power, geothermal energy, water or tidal power) * Effectively inexhaustible: Solar power
there are three main kinds of energy. these are renewable, nonrenewable, and inexhaustible. renewable resources are resources that can be replaced over time. non renewable resources are resources that can not be replaced in a reasonable time. inexhaustible resources are resources that are constantly produced.
Geothermal energy, where we use the heat from deep under the earth to generate electricity, is renewable, that is, there is so much of it that we can keep using it practically forever. Some geothermal plants may over time use up all the heat in that particular location. The power plant may have to be shut down for a few years till the heat renews from deep in the earth. Strictly speaking geothermal energy is…
Wind and solar energy are examples of renewable resources. There is a (practically) inexhaustible supply of each. Geothermal energy is another, less exploitable source of energy. Hydroelectric power can be considered renewable in the short term, providing the water is not diverted to other locations. Tidal power is another constantly available form. Wood, since it is made from trees, can be grown and replenished, but cannot have wide usage to provide energy for modern societies.
