Home Energy Source Alternatives – Are We Ready for Geothermal Energy
The concept of geothermal energy dates back to the time when Romans were able to successfully harness the earth’s natural energy for heating their baths. Historical records are awash with evidences proving that early civilizations have used the heat that emanates from the earth to cook or heat their food. Today, geothermal energy offers a practical option in cooling and heating our homes. This is not just an alternative energy source that is easy on the pocket but also friendly to the environment.
Modern geothermal systems which are sometimes referred to as ground-source heat pumps rely on the natural heat of the earth in heating or cooling the building or home interior. The first generation of heat pump systems of this type went into operation during the 1940s. The main drawback of this early generation of geothermal systems is their steep price. It also required a large land area for its installation. This is the main reason why it was never considered as a viable option for commercial use.
With the rising cost of fossil-based fuels, renewable and non-conventional sources of energy are becoming viable alternatives. Major players and stakeholders in the energy and power generation sector are now looking for ways in fine-tuning geothermal technology. There are now advanced applications that can be used in delivering and harnessing geothermal energy in a more efficient and cost-effective manner. Modern heat pumps can now be easily set up. With these developments and enhancements in the system, you can now consider this system as a viable alternative not only for commercial use but also for home use.
Staunch advocates of clean energy rank geothermal energy high in their list of alternative energy sources. If you use geothermal energy, you help reduce the amount of toxic emission in our atmosphere. Geothermal system is also a healthy and safe cooling and heating option for your home since it does not rely on external source of air. This means that the air inside your home is kept clean and free of pollutants, pollens and harmful elements. This is the main reason why geothermal energy was dubbed as the most environmentally-sensitive and energy efficient air conditioning system.
Another advantage of ground source types of heat pump systems is that they are 50 to 70% more efficient than other types of heating systems. They are also 20 to 40% more efficient than other air conditioning systems. On both aspects, geothermal based heating system is the more practical option.
The use of geothermal energy easily translates to 60% savings in energy cost. Provincial power utilities are strongly recommending for homeowners to switch to this alternative energy source. For instance, Manitoba Hydro has launched their own support program to encourage homeowners to set up their own geothermal systems. The program offers homeowners with loans up to a maximum amount of $15,000 to support the installation of geothermal systems in homes.
Based on current power rates, homeowners will be able to recover their initial investment in setting up their own ground source heating system in about 8 to 10 years. On the other hand, if the heating system will be financed under the Manitoba Loan program, total investment can be recovered in 15 years. In fact, there will be instances where the amount you will save in terms of reduced energy cost will be enough to pay for the loan.
Considering the advantages that ground source heating systems offer to homeowners, it is just but logical and practical for you to seriously consider one for your home. If we take into account other intangibles, then there is no question that going geothermal is not just an alternative but the standard in the way we are going to power up our homes.
