Abstract: Energy demand is increasing exponentially with growth of population , urbanisation , industrialisation and improvement in living standard. This putting high pressure on fossil fuels consumption. These are available in limited amount and will be depleted in next few decades in most of countries as well causes environmental pollution. The renewable energy resources will never exhaust and have capability to meet our future energy demand . In this paper we will study the solar energy resources at various districts , tehsils & sub-tehsils of the Himachal Pradesh , India and further we will discuss the suitability of solar energy. For this, Solar Radiation GHI Data monthly average for 7 years is studied i.e. January 2002 to December 2008. Himachal Pradesh has good non-conventional hydro potential also.

Keywords: Renewable sources, fossil fuels, solar energy, GHI and DNI.
