1) Name an environmental impact and benefit for each of the following energy sources: a) solar,
b) biomass
2) What is Radiative Forcing? Explain the positive and negative radiative forcing and give
examples.
Solution
1)Due to use of Solar and Biomass the pollution occuring now a days can be minimized.As these
two sources are natural sources and did not produce any harmful gases which causes global
warming and depletion of ozone layer and can acheive high reduction in pollution
a)By using solar energy the combustion of coal in the thermal powerplants can be minimixed
which reduces the emission of dangerous cloro floro carbons
b)Biomass is a natural resource for energy production which will not effect the environment.
2)Radiative force is defined as the difference of insolation (sunlight) absorbed by the Earth and
energy radiated back to space.Typically, radiative forcing is quantified at the tropopause in units
of watts per square meter of the Earth\'s surface. A positive forcing warms the system, while
negative forcing (more outgoing energy) cools it. Causes of radiative forcing include changes in
insolation and the concentrations of radiatively active gases, commonly known as greenhouse
gases and aerosols..
