Chlorophyll provides the green color most plants are known for while absorbing light energy from the Sun. When the photons from that energy interact with the chlorophyll's electrons—which were ...

Photovoltaic cells, first developed at Bell Labs in 1954, contain semiconducting materials that absorb light energy from the sun and produce a flow of electrical energy in response. These are the ...

Virtually all organic material on Earth has been produced by cells that convert energy from the Sun into energy-containing macromolecules. This process, called photosynthesis, is essential to the ...

Solar power comes from the Sun so it is a renewable energy source. Life on Earth depends on the Sun. Plants convert the Sun’s light energy into chemical energy that lets them grow and survive ...

Heat energy from the Sun is absorbed by everything on Earth, including us. While light energy from the sun makes things visible (if you've got your eyes open). People have invented ways to ...

Rooftop solar panels use a material, called silicon, to help transform some of the sun's light into electrical energy. This electrical energy then flows into the house, where it's used to power ...
