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
