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

The heat and light we require is insufficient during the night time and winter seasons and people must use fuels as a possible alternate heat energy. Wood and standard fuels include the most frequent alternate heat source as well as the abuse of those sources are causing climate change which in turn cause climate changes. Scientists are developing a eco-friendly treatment for combat the damage why these fuels have caused. One solution is the usage of solar heat panels which harnesses the sun's energy providing heat and light during the winter.

To make the energy useful, the heat energy harnessed from the sun needs being stored and used when needed. The two areas of solar panels is they generate heat and store the heat energy.

The black metal plates within the solar panel's box absorbs the sun's energy. The panels are placed on rooftops facing the sun's rays along with the sun's radiation heats the liquid tubing inside collector. Antifreeze chemicals, air and water would be the usual liquids within the tubing and may heat up to 180 degrees Fahrenheit.

The panels heat which includes been stored provides light and warmth during the winter time when fossil fuel cost is higher and unaffordable.

The damage that's being done for the Earth with all the usage of non-renewable fuels daily will possess a continued effect to future generations unless something is done. If solar panels were used world-wide and fossil fuel use brought to a substantial crawl, our planet could be potentially saved from further harm.

Geothermal Energy is an additional type of renewable energy resource that makes use of the large numbers of energy stored as heat in the water deep below the Earth's surface using the most prominent and visual example with this via "Geysers" and "Hot Springs" ejecting large columns of very hot water, steam and gases high up into the air. In fact the phrase "Geothermal" originates from combining together both Greek words of Geo, meaning "Earth", and Therme, meaning "heat", with the resulting word "Geothermal" actually meaning "heat generated from your Earth", then a expression "Geothermal Energy" literally means "heat energy generated in the Earth".

Geothermal energy is obtained through the hot areas within the surface in the earth that remain at a relatively constant temperature all year around day and night. Once available, geothermal energy could be used either directly or indirectly as an alternative energy resource to both heat and cool our homes. This naturally occurring and free energy is extracted by a compilation of pipes filled with water buried below the Earths surface. This warm water is then used in our homes for heating, called Geothermal Heating, or generate electricity, called Geothermal Power.

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

Sometimes the hot magma reaches entirely on the Earth's surface being a volcanic eruption, but usually the magma remains underground and heats the adjoining rock too just like any water that has seeped down through geologic holes, cracks and faults in the Earth's crust absorbing the heat as it travels with these hot rocks. Some on this water, whose temperatures can reach of up to 700 degrees, travels back 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 inside the rock, forming a natural underground geothermal reservoir. It is these underground geothermal reservoirs which are able to give to us another kind of alternative energy resource with incredible potential.

Let us understand that geothermal is NOT mining, as mining removes the mined material forever, it is extraction in the heat coming from a hydrothermal fluid which can be replenished, sometimes over lengthy periods by the Earth itself. This geothermal energy resources could be used either for direct consumption, heating or for power generation in a single from the following three main ways:

Types of Geothermal Energy

Direct Geothermal Energy - that is the place that the domestic hot water can be obtained either on or very close towards the Earth's surface and could be used directly for heating, bathing or washing. Ground Source Geothermal - this can be where the geothermal hot water is below the soil but less than deep allowing easy access in the geothermal resource using heat absorbing pipes or bore holes. Geothermal Power Plants - these harnesses the extremely domestic hot water or steam using vertical bore holes drilled deep underground then uses the available super heated geothermal water and steam to generate electricity. For domestic applications, one way of extracting this heat energy is from the use of the 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 because the domestic refrigerator but in reverse.

A Geothermal Heat Pump, also known as a "Ground Source Heat Pump", is a effective strategy to heat and air-condition our homes and buildings as it might move heat in 2 ways: throughout the colder winter months, low temperature heat is withdrawn from your ground (the heat source) for direct used in heating buildings and other structures. In the hotter summer months, the geothermal heat pump operates in reverse detaching the heat through the building and dissipating it back into the ground.

As an outcome with this simple process, direct use geothermal heating has become extremely popular for that house owner because it offers a cost-effective alternative to expensive oil or gas home heating systems. Energy savings utilizing a ground source heat pump may be substantial over a good duration of time.

Geothermal power on another hand uses extremely hot water heated by the underground magmatic activity which is pumped towards the surface and employed for electricity generation. Once this super heated water reaches atmospheric pressure it turns to steam where it really is used to operate steam-powered turbines and generators. Geothermal power plants are more and more common in volcanic areas and countries such as Iceland, were it makes over a quarter of their energy needs.

The main features of Geothermal Power is which it is clean, cheap, no additional fuel is necessary leading to no greenhouse gases or air pollution. However, some disadvantages include ground water and waste water pollution, geographically restricted and maintenance costs. But the largest disadvantage is how the closer you put a Geothermal power plant to an active volcano or heat source, the larger the possibility operational problems you are able to have.
