The primary heat energy provider for your Earth may be the sun. It mediates the temperature and controls the water cycle individuals planet and supplies the existence of life.

The heat and light we need is insufficient during the night time and winter seasons and people need to use fuels being an alternate heat energy. Wood and non-renewable fuels are the most common alternate heat source as well as the abuse of the sources are causing climatic change which subsequently cause climate changes. Scientists are creating a eco-friendly treatment for combat the damage these fuels have caused. The type of solution is the utilization of solar heat panels which harnesses the sun's energy providing heat and lightweight during the winter.

To result in the energy useful, the heat energy harnessed in the sun needs to become stored and used when needed. The two aspects of solar panels is that they generate heat and maintain heat energy.

The black metal plates inside the solar panel's box absorbs the sun's energy. The panels are put on rooftops facing the sun and also the sun's radiation heats the liquid tubing within the collector. Antifreeze chemicals, air and water are the usual liquids inside tubing and can heat approximately 180 degrees Fahrenheit.

The panels heat which includes been stored provides light and warmth through the winter season when fossil fuel pricing is higher and unaffordable.

The damage that is being done to the Earth with all the usage of standard fuels daily will have a continued effect to future generations unless something is done. If solar panels were utilized world-wide and fossil fuel use brought to a substantial crawl, our planet might be potentially saved from further harm.

Geothermal Energy is another kind of renewable energy resource that makes use from the large amounts of energy stored as heat in the water deep below the Earth's surface using the most prominent and visual example on this coming from "Geysers" and "Hot Springs" ejecting large columns of very hot water, steam and gases high up in the air. Actually the saying "Geothermal" comes from combining together the 2 Greek words of Geo, meaning "Earth", and Therme, meaning "heat", with the resulting word "Geothermal" actually meaning "heat generated from the Earth", then your expression "Geothermal Energy" literally means "heat energy generated from your Earth".

Geothermal energy is obtained through the hot areas under the surface from the earth that remain with a relatively constant temperature all year around day and night. Once available, geothermal energy can be used either directly or indirectly as an alternate energy resource to both heat and funky our homes. This naturally occurring and free energy is extracted by the series of pipes full of water buried below the Earths surface. This domestic hot water is then utilized in our homes for heating, called Geothermal Heating, as well as to generate electricity, called Geothermal Power.

So how can it work. At the Earth's core, some 4000 miles below the surface, temperatures can reach over 9000 degrees Fahrenheit. This incredible level of heat originated four billion years ago inside a fiery combustion of dust and gas because the Earth was being created. Many scientists feel that radioactive decay in the inner core keeps the heat generating and flowing outward out of this inner core for the mantle of harder rock which surrounds the core. When the temperature and pressure is high enough, some on this mantle rock melts. Then, as the melted rock or magma is less dense as opposed to surrounding rock, it rises and moves slowly up towards the Earth's crust.

Sometimes the new magma reaches entirely for the Earth's surface being a volcanic eruption, but usually magma remains underground and heats the adjoining rock too every water which includes seeped down through geologic holes, cracks and faults inside Earth's crust absorbing the heat as it travels with these hot rocks. Some with this water, whose temperatures can reach up to 700 degrees, travels backup through cracks on the Earth's surface and emerges as hot springs, geysers or pools of boiling mud. Far more often, however, the water and magma becomes trapped from the rock, forming a natural underground geothermal reservoir. It is these underground geothermal reservoirs which are able to give us another type of renewable power resource with incredible potential.

Let us understand that geothermal is NOT mining, as mining removes the mined material forever, it really is extraction with the heat from the hydrothermal fluid which can be replenished, sometimes over very long periods from the Earth itself. This geothermal energy resources could be used either for direct consumption, heating and power generation in one of the following three main ways:

Types of Geothermal Energy

Direct Geothermal Energy - this is in which the hot water can be acquired either on or very close to the Earth's surface and may be used directly for heating, bathing or washing. Ground Source Geothermal - this really is in which the geothermal domestic hot water is below the bottom but not very deep allowing comfortable access in the geothermal resource using heat absorbing pipes or bore holes. Geothermal Power Plants - these harnesses the extremely warm water or steam using vertical bore holes drilled deep underground and after that uses the available super heated geothermal water and steam to create electricity. For domestic applications, one way of extracting this heat energy is by the use of an Geothermal Heat Pump. The geothermal heat pump doesn't create electricity, instead it circulates a thermally conductive liquid mixed with water through long pipes called an Earth loop buried approximately 12 feet underground, operating about the similar principle as the domestic refrigerator but also in reverse.

A Geothermal Heat Pump, also known like a "Ground Source Heat Pump", is often a effective method to heat and air-condition our homes and buildings as it might move heat by 50 percent ways: throughout the colder winter months, low temperature heat is withdrawn in the ground (the heat source) for direct use within heating buildings as well as other structures. In the hotter summer months, the geothermal heat pump are operating in reverse removing the heat through the building and dissipating it back in the ground.

As an effect with this simple process, direct use geothermal heating is becoming popular for that house owner given it offers a cost-effective substitute for expensive oil or gas home heating systems. Energy savings employing a ground source heat pump might be substantial over a lengthy amount of time.

Geothermal power on another hand uses extremely warm water heated from the underground magmatic activity which can be pumped to the surface and employed for electricity generation. Once this super heated water reaches atmospheric pressure it turns to steam where it really is utilized to operate steam-powered turbines and generators. Geothermal power vegetation is more and more common in volcanic areas and countries like Iceland, were it produces on the quarter with their energy needs.

The main advantages of Geothermal Power is which it is clean, cheap, no additional fuel is required causing no greenhouse gases or air pollution. However, some disadvantages include ground water and waste water pollution, geographically restricted and high maintenance costs. But the largest disadvantage is how the closer you place a Geothermal power plant to a active volcano or heat source, the bigger the potential operational problems you are able to have.
