Question

introduction of non conventional sources of energy

Answer 1

hey dear,

Alternative energy has received more attention in the national and international media as the pollution from fossil fuels becomes more apparent. Global warming and declining air quality are two effects of society's dependence on fossil fuels. By introducing alternative energy sources into your own daily life, you can help save the environment and reduce your use of the decreasingly affordable petroleum-based fuels.

hope it helps
