Do you think geothermal energy is a renewable resource? Why or why not? What are the benefits of using this energy to power home
Keith_Richards [23]
Geothermal is a renewable energy, because it is from the heat produced by the earth. The earth gets heat from the sun, which will be there for the next million of years. Geothermal has benefits, because if we harness the use of it, instead of mining out all of our coal and oil, we can use this for a long run, and only leave non-renewable energy resources for backup. However, there are consequences to communities and surroundings. The geothermal only benefits when the earth is warm. When the earth becomes too warm, we wouldn't even need the energy anymore cuz everythings dead. So we can use this, but overall we must try to lower the amount of resources that produce this thing as possible.. ( use other renewable energy)

hope this helps
