With the urgent need to address climate change universally expressed at the COP26 United Nations Climate Change Conference, many wonder how can we accelerate the path to net-zero? The answer may lie beneath our feet – with geothermal. Geothermal is the heat produced by the earth's subsurface (the term comes from the Greek words geo (for earth) and therme (for heat)). Our planet's core is as hot as the surface of the sun,1 and there are estimates that just 0.1% of its heat content could supply humanity's total energy needs for millions of years.2
