Evolution of Geothermal Energy From Hot Water Springs

Geo-thermal heating is one of the widely used technologies these days to provide heat to commercial as well as residential establishments. Geothermal projects are especially common in Mechanicsburg. A lesser known fact is that, geo-thermal energy has been used since ancient human civilization for various purposes. The use of this energy has undergone a gradual change over the years. Following is a brief description of the different uses of geothermal Mechanicsburg.

Uses of Geo-thermal Energy: Hot water springs to Geo-thermal Mechanicsburg

Hot Water Springs

Long before geo-thermal projects began in Mechanicsburg, people way back in ancient times used geothermal heat directly. Geothermal heat consisted of hot water springs. People used to bathe leisurely in this water. Natural temperature of water usually exceeds the 300 degrees F mark.

Farming and Agriculture

This energy was then used for agricultural purposes. People used heat to raise crops in greenhouses during the winter season. Moreover, farmers also made use of geothermal heat to dry onions and wash wool. Geo-thermal energy was also utilized to raise fish farms.

Drilling of Wells

Later on, geo-thermal energy was used for other purposes such as drilling of wells. The water in the wells was then brought up to generate electricity.

Modern Uses of Geo-thermal Energy

Space Heating

Space heating of districts is another use of geothermal energy. Usually in such systems the heated water is passed through the heat exchangers and pipes to provide heat to different buildings. These systems are used in Romania, Iceland and Sweden. This energy is also used to provide heat to commercial buildings as well.

Power Generation

Power generation is yet another modern use of geothermal energy. Heat is used to spin generators in geothermal plants. Power is thus produced in a cheaper manner with this method. This method is environmentally friendly and does not produce any toxins.

From hot water springs to geo-thermal energy in Mechanicsburg, technology has certainly come a long way.…

Geothermal Technology: The Undiscovered Green Technology

If you have ever been in a cave, you probably remember how cool it was. All caves are about the same temperature: around 55 degrees Fahrenheit (13 degrees Centigrade). Dig down about 6-8 feet (2 to 2.5 meters) in your back yard and you have a similar effect. The ground is a relatively constant temperature of around 55 degrees F.

Therein lies the basis for geothermal technology that offers an essentially limitless source of non-fossil fuel based energy. Geothermal technology, also referred to as geo-exchange, takes advantage of the constant temperature zone underground and uses it as an enormous heat sink to absorb heat in the warmer months. Then, in winter when heating is desired, the same constant temperature becomes a heat source to offset the need for other energy sources to provide heating. All that is needed is a system of pipes buried in your back yard that can carry out efficient heat exchange, providing cooler air for you home in the summer and warmer air in the winter.

The idea is simple, but the technology is not simplistic. Systems should be well-engineered to maximize heat transfer and create maximum efficiency. But when done properly, the payback, especially if included in a new construction, is faster than that offered by solar or wind power.

Geothermal technology is not a new idea, but it has been ignored compared to more popular and popularized technologies such as solar photovoltaic panels, wind power, and biofuels. But the benefits of geothermal technology are compelling.

First of all, geothermal heating and cooling emits no greenhouse gases at all. It could also help countries become more energy independent and less reliant on sources of imported oil and gas.

A second benefit is that geothermal technology is not dependent on the vagaries of the weather. The geo-exchange process functions 24/7. The results are the same whether it is sunny or not, and regardless of whether the wind is blowing.

Then there are the economic advantages. A geo-exchange heating and cooling system works with existing ducts and reduces the need for heating and cooling from your already installed systems. As an add-on, a new geothermal exchange system can provide a payback of around 10 to 15 years without taking into account any government incentives. Depending on where you live and the incentives available, the payback in your specific case can be much shorter, as little …
