Iceland is almost on the Arctic Circle, so the climate there is often extremely cold. The ground is a great insulator with respect to heat. Underground homes anywhere in the world can remain at a constant comfortable temperature with very little help from artificial heating or cooling.
Consider the fact that public utilities distribute water to homes via underground pipes. No matter how cold it gets outside, when you open the faucet, it still comes out liquid.
Their homes and property were used as rest stops for the slaves to stay at.
Geothermal power plants in Iceland harness the heat from underground reservoirs to generate electricity and provide heating to homes and businesses. Geothermal heat pumps are used in many buildings worldwide to provide heating, cooling, and hot water by leveraging the stable temperature of the earth's subsurface.
There a re various joint and vales. Sometimes booster pumps .
I believe you mean what was the underground railroad used for. And the answer to that is, during slavery, it set people free because no slave owners knew about it and that is how slaves would escape from slavery/slave owners.

Natural gas is the fossil fuel that reaches homes through underground pipes. It is a clean source of energy that is used for heating, cooking, and powering appliances. The natural gas is transported through a network of pipelines that deliver it directly to residential areas.
Natural Gas heats homes cuz its nonrenewable,and natural resource.DUH!
The hot water geysers in Iceland have been capped and are used to provide "free" electricity and heating in Iceland.
Iceland is a good example (because of the geology of the area) the undergraound heat radiating out from geothermal process' can be harnessed into renewable heating supply for homes ect.
Underground mines consist of a series of parallel and interconnecting tunnels from which the coal is cut and removed with special machinery. The process is complex and sometimes dangerous.
dung is animal waste that is sometimes used to make homes (ants) or to feed other animals.
