Iceland and New Zealand are two places in the world where geothermal energy provides a cost-effective energy resource because these countries have an active volcanic area.
Geothermal- Geothermal energy is a kind of energy that human gets from the heat of the earth. This is a kind of renewable energy because the earth produces a large amount of heat.
The high temperature of the interior makes the rocks melt and the molten rock comes into the crust of the earth in the form of lava.
