- 7. ZERO ENERGY BUILDING Geothermalenergy THIS ENERGY IS TAKEN FROM THE EARTH THE HEAT PRODUCED BY EARTH IS CONVERTED INTO ENERGY • One percent of the heat contained in just the uppermost 10 kilometres of the earth’s crust is equivalent to 500 times the energy contained in all of the earth's oil and gas resources. • The temperature of earth varies proportionally with depth. We can utilise this temperature to produce limitless energy.
