Energy efficiency is becoming a sensitive subject more than ever. Companies are coming up with different technologies to use energy more efficiently. One technology that has recently got introduced to the public is Geothermal Heat pumps. A geothermal heat pump (GHP) system is a central heating and/or air conditioning system that actively pumps heat to or from the shallow ground. It takes advantage of this by transferring heat stored in the Earth or in ground water into a building during the winter, and transferring it out of the building and back into the ground during the summer. While most people are switching to this source at a fast rate and there is no study portraying the side effects of the system on our environment. Washington Department of Fish and Wildlife have noticed an increased amount of these systems installed illegally in Lake Washington homes. One reason to which why this is happening is that the current permitting system is lengthy. As an intern for the Department of Ecology and Department of Fish and Wildlife my job was to gathers different documents on the geothermal heat pumps and the effect it has on our environment. Furthermore analyze the different drawbacks and benefits of using GHPs and proposes a recommendation of how to come up with an environmentally friendly GHP and a better permitting system in Washington.
