what is the Mid-Atlantic ridge

30%

The energy produced from the heat of the Mid-Atlantic ridge equates to around ___ of Iceland’s electricity production

how is electricity produced from the Mid-Atlantic ridge

emission-free, sustainable, ¾ of population lives near geothermal sources (Reykjavik)

name three positive aspects of this energy production

high cost, visual pollution, may release dangerous underground gases
