Two sources of light energy include the sun and incandescent light bulbs.
The two main sources of light energy are natural light from the sun and artificial light from sources like light bulbs and lamps. Both sources produce electromagnetic radiation that our eyes perceive as light.
The two types of thermal energy sources are Geothermal and Thermal Energy

The sun gives off light and heat through the process of nuclear fusion in its core. These two forms of energy are essential for sustaining life on Earth and are the main sources of energy for many ecosystems.
nuclear energy and burning fossil fuels to push turbines that make electricity. ************************************************* the two main sources are burning lots of fossil fuels and nuclear energy
Light and heat
Heat energy and light energy when the current passed through them.
The two sources of energy suggested by Oparin's theory were ultraviolet light and lightning. These energy sources were thought to have provided the necessary energy for chemical reactions to occur and form organic molecules in the early Earth's atmosphere.
The two energy sources created in the light reactions of photosynthesis are ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules carry energy that can be used in the Calvin cycle to produce carbohydrates.
there are not just two electrical sources of energy there are lots but two could be solar and biomass

The sun and the earth's interior are the two sources of energy that power earth's systems.
