Chemistry Notes for B.Sc. and M.Sc.

  Renewable sources of energy   are the sustainable energy sources because the se   are not depleted with usage as they can be replenished either naturally or manually within the short time scale and hence can be used again and again. Advantages/Benefits of Renewable sources of energy ü  Ensure energy Security ü  R educ tion in   greenhouse gas emissions, ü  Help to combat   the change s in   climat ic conditions   T ypes of   Renewable sources of energy 1. Solar Energy Solar energy   is one of the most abundant and widely used renewable source s of energy which can be used as follows: i.  Either directly as heat for solar heater for boiling water/preparing food etc. ii.  Or converted   to electricity using Photovoltaic (PV) Solar Panels   which is then used as energy source for diverse purposes. Photovoltaic (PV) Solar Panels : These are the panels prepared using semiconductor materials (e.g., silicon) ...
