Take Home Message The problems of population
and energy demand are not going away
Solar capabilities are now available for use
As solar technologies become more prevalent costs will decrease, and use will further increase
Passive solar and active solar heating technologies are already cost effective; photovoltaics will soon followwww.louisehauck.com
