Save electricity

Install metal roofs
Metal roofs reflect much more heat away from your home than do regular asphalt shingle roofs.
 
Plant tree
Well-positioned shade trees can reduce indoor temperatures by up to 20 degrees and energy use by up to 40%.

White roof
When you replace your roof, metal is best.  If you don't go with metal, then at least go with white.  A white roof typically saves 10%, and up to 20% on cooling costs.

Paint the exterior with a light color
The next time you have your home painted, use a light color. Dark colors increase cooling costs by 20% compared to light colors.

Replace Air Con.
According to Austin Energy, today's AC's [2005] use 30-50% less electricity than 15-year-old models.

Spin the fans
Fans can make you feel 3 to 8 degrees cooler, allowing you to dial your AC to a higher temperature and still feel just as cool.
