Geodelphia

Advocating geothermal for Philadelphia’s heating and cooling needs

Philadelphia’s climate neighborhoods

Did you know that 60% of Philadelphia’s carbon footprint comes from heating and cooling our homes and buildings? But what if we could slash that to almost zero, save money, make our homes safer, AND be heroes to the next generation, all at the same time? If this sounds good, read on!

Geothermal is a tried and true technology which can accomplish all that and more. For 40 years people have been running water pipes underground, then sending them through heat pumps to warm indoor air in the winter and cool it in the summer. Most of the energy needed to do this is going unused, ten feet or so underground – solar energy stored in the earth. Run some pipes down there, add a small amount of power to run the heat pump and you get practically free heating and cooling. And if that electricity comes from renewables like solar or wind, it is almost entirely climate-neutral.

So why didn’t we all switch our oil, coal or natural gas systems to geothermal years ago? Mostly because of the initial cost of drilling into the earth. Yet increasingly there are ways to make this up-front cost manageable, no matter the size of your home or building.
