Renewable energy energy is an important alternate source of energy. why?

Renewable energy is important because, unlike nonrenewable energy, renewable energy sources replenish overtime.

Explanation:

Nonrenewable energy sources, such as fossil fuels, will eventually run out because they do not replenish in a reasonable amount of time. On the other hand, renewable energy sources, like windand solar power and biofuel, are unlimited or practically unlimited.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.
