Which invention has helped people to survive and settle in very cold climates the most?

One of the greatest inventions that has become key to the survival of many humans is the solar powered generator. In some colder climates, gas may not be easily accessible to all to be able to run gas powered generators. The solar powered generator is able to run purely off of the power created by the sun and does not require any other form of energy, such as gasoline.

There is a long history of solar technology, but it is rumored that the first solar power to turn into electricity was in 1883 and was created by French Scientist Edmond Bacquerel.
