As non renewable sources of energy are fast depleting, we must bring into use renewable sources of energy which are easily available as per the topography of the area.

a. Rural areas: Rural areas would have resources like Biogas, firewood in abundance. So it can be used as a source of energy.

b. Coastal areas: Coastal areas experience fast winds, so Wind energy can be used as a source of energy.

c. Arid regions: Arid regions have high temperature and ample of sunlight. Solar energy would be suitable source of energy.
