Geothermal Energy

On Monday February 23, we had another guest lecture. It focused on another renewable energy source: Geothermal. According to the lecturer, geothermal is the most efficient renewable source out there. This lecture focused on Earth River Geothermal-which installs geothermal energy systems in mainly residential areas in Maryland. The reason geothermal is so efficient is that it uses the earth, which stays at 57 degrees all year round (10 feet below the surface). With other renewable energy sources such as wind or solar, there is always a chance of a day with less energy being produced. On windless or cloudy days these energy sources will not be able to produce as much energy. Since below the earth's surface remains at a constant temperature, whether it be summer, winter, sunny or rainy, the same amount of energy will always be guaranteed. I went ahead and researched a little bit about geothermal energy companies in Delaware, since that is where I live. I found a site that listed all or at least many of the geothermal contractors in Delaware (it also lists some in Maryland and Pennsylvania). I had no idea there were so many. One company that was highlighted in many of the google searches was the A&A Companies. They offer closed loop geothermal heating and cooling systems since they suggest that closed loop are the safest and most environmentally friendly way to heat/cool your home. The site offers demonstrations of how the geothermal process works for cooling and heating your home.
