2- Thermostatically controlled,whole house attic fan...
3- ceiling insulation,typically blown in..
Simple rule for electrical useage, if it produces heat, don't have it powered by electricity..ie hot water heaters,ovens/stoves, clothes dryers...AC's you really don't have a choice..
Solar panels are very effective and actually have been in use in Fl for over 50 yrs..However, the current cost payback time is long..
hope this helps

I fully agree rp001. I have been in many an attic throughout the Villages and I see many retrofit radiant barrier systems installed incorrectly. Unfortunately the "all mighty dollar" brought out the scammer looking to make a buck on the radiant barrier boom. The product is very very effective if installed correctly. Department of Energy states approximately 10% reduction in cooling costs can be attributed to the use of properly installed radiant barrier. Radiant barrier should be in stalled on the backside of the roof trusses with proper aluminum tape to encapsulate the entire roof area. The gist of the story is the product works effectively when properly installed. Read up on any product you buy and ask questions. The internet is a wonderful tool to find out the truth behind many products you may see out there.
