What is the main difference between traditional geothermal energy and terrestrial energy from ground-source heat pumps? Group of answer choices Traditional geothermal supplies almost 10% of our current world energy mix, whereas ground-source heat pumps are a brand new, emerging technology. Traditional geothermal has to be extracted from an area where the heat flow is unusually high; ground-source heat pumps are more broadly applicable. Traditional geothermal energy is much cheaper to produce than energy derived from ground-source heat pumps. Traditional geothermal can only be used for heating and cooling, whereas terrestrial energy from ground-source heat pumps has many applications. Traditional geothermal energy can be utilized in Ontario, but we don't have any viable terrestrial energy sources
