What are two ways in which the suns energy can be captured and used? How can both be used in a home?
Answers
The following exist:
Artificial photosynthesis: Plants can photosynthesize, but we can do it artificially to power anything requiring energy.
Solar thermal energy or STE is a process where the light is reflected from a mirror or lense to heat up anything.
Photovoltaics or Heat collectors (Solar panels): they absorb the sun's electromagnetic energy and converts it into electricity.
All of these technologies are very similar to each other... this was a good question
Photosynthesis is a great example: plants use the sun's energy to grow and reproduce. Solar energy-power from the sun is a vast and inexhaustible resource that people have recently discovered and it's used for light and heat.
