In one hour ,the sun pours as much energy on to the Earth as we use in whole year..Is it were possible to harness this colossal quantum of enefy .Today we have developed several methods of collecting this energy for heaing water,and generating electracity.
Solar heating for homes:Modern houses that use air conditioningand /or heatingare exremely energy dependent.A passive solar home or building is designed to collect the sun's heat through large,south facing glass windows.In solar-heated buildings ,sunspaces are built on the southside of tje structuring and act as large heat absorbers.The floors of sunspaces are useually made of tiles or bricks thatabsorb heat throughout the day,then release heat at night when it is cooler.
