So You Think You Know Renewables? Take the Quiz

Shining solar cells, whirling wind turbines, massive dams and advanced geothermal heat pumps are all crucial pieces of infrastructure that currently generate renewable energy. And they'll likely play a big role in the future as the world looks to slash carbon dioxide emissions.

But these seemingly new technologies each had humble beginnings many years ago. In fact, it may surprise you just how many years ago. Go ahead and test your renewable energy expertise by guessing their birth years below.

The poll is completely bogus—you ask one set of questions, but then answer a different set.

Solar power, wind power, hydropower and geothermal energy have all been used for centuries, if not millennia.

Dutch windmills, the piedmont water mills, Archimedes screws, and geothermal Roman bathhouses all far predate the answers given.

If you have electrical power production in mind, ask that.

you have incorrectly mixed geothermal heat pumps in your text with geothermal steam generation in your question.  i would be happy to send you the Geothermal Exchange Organization’s geothermal temperature spectrum which describes hot temp geo, direct use geo (mid temp) and geothermal heat pumps (low temp)

Regarding the quiz answers:  Power/energy is not invented; it is discovered. These are the methods through which energy can be utilized.
