I would suggest hydro power, but it's not available everywhere. Otherwise wind power.

Bacteria that use sunlight as an energy source are considered phototrophic. They use light energy to drive photosynthesis, converting it into chemical energy to fuel their metabolism. Examples include cyanobacteria and green sulfur bacteria.
Most of the visible light spectrum except green wavelengths is absorbed by the chlorophyll molecule and is usable in photosynthesis as a source of energy for plants.

Olive oil is man's best source of energy.
Probably we (mankind) will have to use a variety of energy sources, not just "one best" energy source.Probably we (mankind) will have to use a variety of energy sources, not just "one best" energy source.Probably we (mankind) will have to use a variety of energy sources, not just "one best" energy source.Probably we (mankind) will have to use a variety of energy sources, not just "one best" energy source.
The source of energy of plants is sunlight.
Glucose is the only energy source that the brain can use.
Carbohydrates
Green plants continuously use carbon dioxide, water, and sunlight to perform photosynthesis, a process that allows them to produce oxygen and glucose as a source of energy for growth and maintenance.
