Dramaticas this was, it wasjust oneuse
of solar energy.
Tomany students, exciting projects like this
arewhat solar energyisall about.
But there reallyismuchmore tosolar energy
technologies, how they are beingusedand
how they impact our lives today. This
presentation will introduce youtothe
entire field of solar energy.

Sowhichview of solar energy
--for thefuture or for today -
iscorrect ?
Probably alittle of both.
Solar energy will certainly playan
important rolein thefuture energy needs
