Our Most Plentiful Resources Which two renewable technologies do not
rely on energy from the Sun?
wind and hydroelectric

Explanation:

None of them.

Without the sun driving weather pattern, the energy from wind would be marginal at best. Without the sun, water would not evaporate from oceans and condense over high ground causing rain to fill rivers and reservoirs for hydroelectric.

Biofuels are also considered renewable. Don't work without the sun to grow crops.

Even oil and coal are products of the sun. Plants and algae living millions of years ago converted carbon dioxide into plant material that eventually got converted to these sources.

Even nuclear energy relies on star power as all elements heavier than iron must be forged in a supernova explosion. Uranium and the other fissile fuels are all heavier than Iron. Only fusion reactions, which we have used as bombs, but not for peaceful domestic purposes, produce energy without the sun or a star.
