The world needs a new source of energy, an unspillable source.

What are different ways to conserve electricity?

I have heard about using solar panels…does anyone have any information on this…I own a 2-story approx 2450 sq.ft. home….When I first bout the house it had double-paned windows…newer model DR Horton Home…I changed all light bulbs to the new efficient flourescent bulbs…all energy-star appliances….is there anything else I can do…I am really interested in learning more about Solar-Panels…I live in the San Antonio, TX area…Thanks in advance…
