The primary heat energy provider to the Earth may be the sun. It mediates the temperature and controls water cycle in our planet and offers the existence of life.

The heat and light-weight we want is insufficient during the evening and winter seasons the ones have to use fuels as an alternate heat energy. Wood and non-renewable fuels include the most popular alternate heat source as well as the abuse of these sources are causing global warming which consequently cause climate changes. Scientists are developing a eco-friendly solution to combat the damage why these fuels have caused. The type of solution is the use of solar heat panels which harnesses the sun's energy providing heat and light-weight through the winter.

To increase the chance for energy useful, the heat energy harnessed in the sun needs being stored and used when needed. The two facets of solar panels is that they generate heat and maintain heat energy.

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

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

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

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

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

So how will 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 in the fiery combustion of dust and gas because the Earth had been created. Many scientists feel that radioactive decay in the inner core keeps the heat generating and flowing outward using this inner core to the mantle of harder rock which surrounds the core. When the temperature and pressure is high enough, some of this mantle rock melts. Then, since the melted rock or magma is less dense compared to surrounding rock, it rises and moves slowly up towards the Earth's crust.

Sometimes the hot magma reaches all the way on the Earth's surface like a volcanic eruption, but the magma remains underground and heats the adjoining rock as well as any water which includes 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 support through cracks for 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 can be capable to give us another form of sustainable energy resource with incredible potential.

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

Types of Geothermal Energy

Direct Geothermal Energy - this can be where the warm water is available either on or very close on the Earth's surface and could be used directly for heating, bathing or washing. Ground Source Geothermal - this can be the place that the geothermal hot water is below the soil but less than deep allowing comfortable access of 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 then uses the available super heated geothermal water and steam to build electricity. For domestic applications, a proven way of extracting this heat energy is through 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 up to 12 feet underground, operating for the same principle as the domestic refrigerator in reverse.

A Geothermal Heat Pump, also known being a "Ground Source Heat Pump", is really a very efficient approach to heat and air-condition our homes and buildings as it can move heat by 50 percent ways: throughout the colder winter months, low temperature heat is withdrawn in the ground (the heat source) for direct used in heating buildings as well as other structures. In the hotter summer months, the geothermal heat pump operates in reverse removing the heat in the building and dissipating it back to the ground.

As an effect of the simple process, direct use geothermal heating is now very popular for your property owner because it provides a cost-effective option to expensive oil or gas home heating systems. Energy savings employing a ground source heat pump may be substantial over a long duration of time.

Geothermal power on another hand uses extremely hot water heated through the underground magmatic activity which is pumped towards the surface and useful for electricity generation. Once this super heated water reaches atmospheric pressure it turns to steam where it is employed 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 over the quarter of these energy needs.

The main features of Geothermal Power is it is clean, cheap, no additional fuel is required 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 greatest disadvantage is that this closer you place a Geothermal power plant to a active volcano or heat source, the bigger the possibility operational problems you are able to have.
