In the past, people used wind, water and sun energy, but they were not aware that there is a notion like “renewable energy sources”.

WWithout scientific ithout scientific explanation explanation people people werewere::

• BBuilt houses of south - west, to uilt houses of south - west, to "ca"catchtch" sunlight in " sunlight in the bigger the bigger partpart of the day of the day

• Built Built windmills windmills • Built watermillsBuilt watermills

Water and wind energy is transformed into mechanical. For example for grinding flour. Propellers of the windmills are set in motion by wind, they are driven two large stones, and rubbing to each other they are grinding the grain between them in flour.

TThe structure he structure of the watermills is like windmills’ of the watermills is like windmills’ structurestructure. But . But waterwatermillmills ares are driven by driven by water water energyenergy . . They aThey are built on the river flow.re built on the river flow.
