Which three statements provide reasons that scientists are considering renewable sources of energy? most renewable resources are clean and nonpolluting. renewable resources can be replenished. renewable resources are conventional resources. most renewable resources are easily available in nature. all renewable resources are cost effective.

Most renewable resources are clean and non polluting.

Renewable resources can be replenished.

All renewable resources are cost effective.

Explanation:

Scientists are considering renewable resources of energy like sunlight, air, tides, water, geothermal energy etc. because most of them are clean which do not produce harmful gases which pollute atmosphere. Apart from this unlike non renewable resources of energy which once consumed will not be able to be replenished, renewable resources of energy are easily replenished in nature. Renewable resources are quite cost effective because they are freely available in nature in abundance while it takes a lot of efforts to fetch non renewable sources of energy. We need a lot of technologies in order to dig coal basins and oil drilling. So non renewable resources are not that cost effective.
