Out of the following why is solar energy a viable alternative energy resource?
1. It produces minimal air pollution.
2. It costs almost nothing to harness.
3. It has an endless supply.
4. It comes from organic plant materials.
The correct answers are:
1. It produces minimal air pollution.
2. It has an endless supply.
Solar energy is a viable alternative energy resource because it is renewable and does not produce harmful air pollutants, unlike many traditional sources of energy such as coal and oil. Additionally, once the initial investment is made to install solar panels or other means of harnessing solar energy, the ongoing costs are minimal, making it an affordable option for many individuals and communities. Finally, as long as the sun continues to shine, there will always be an endless supply of solar energy available.
Option 4 is incorrect as solar energy does not come from organic plant materials, it comes from the sun.
