Water power and hydroelectric power.
Two sources of energy for water waves are wind, which transfers energy to the water's surface, causing waves to form, and gravitational forces from the sun and the moon, which influence the tides that create waves.
Two sources of energy are solar power, which harnesses energy from the sun using solar panels, and wind power, which generates electricity using wind turbines. Both sources are renewable and produce clean energy with minimal environmental impact.
Two sources of energy that can be converted into electricity by a generator are wind energy, by using wind turbines to turn a generator, and solar energy, by harnessing sunlight through photovoltaic cells to produce electricity.
there are not just two electrical sources of energy there are lots but two could be solar and biomass
energy
Two sources of light energy include the sun and incandescent light bulbs.
The sun and the earth's interior are the two sources of energy that power earth's systems.
The two types of thermal energy sources are Geothermal and Thermal Energy
The sun and the earth's interior are the two sources of energy that power earth's systems.
The two main sources of energy gas and electricity.
The two main sources in water vapor are farming and manufacturing
