OPINION: Geothermal exchange systems a vital tool in fight against climate change

"Geothermal exchange systems, electric vehicles key to eliminating Ontario's biggest greenhouse gas sources, writes Peter DeVita


The United Nations Intergovernmental Panel on Climate Change (IPCC) team has been researching climate issues for over 20 years. World scientists and engineers are telling us we must collectively reduce our greenhouse gas (GHG) emissions by 45 per cent before 2030, or the world could face severe consequences. Our oceans are warming, causing far more severe hurricanes, raising ocean levels as well as releasing dissolved carbon dioxide (CO2). The CO2 added to the atmosphere by the oceans causes more warming — a very dangerous feedback loop. So what can we do now to slow this down and reverse the increase in CO2?


To reduce GHGs we must stop burning fossil fuels (coal, oil and gas)! For Ontario, statistics show that our highest two GHG sources are:


a) Heating buildings using natural gas

b) Transportation using fuels derived from oil


For Ontario, the alternative energy source is electricity. Geo-exchange systems (GX) are the optimum response for building heating, while electric vehicles are the best response for the transportation sector."
