Energy Home Panel Solar
What are the best ways to make my home more energy efficient?
Should i use those new light bulbs?
Have Home Depot put insulation in my attic?
Put Solar Energy panels on my roof?
Install windmills in my backyard?
You can change to CFL's to save a little.
IF your house NEEDS more insulation, this is the most efficient addition. Also, caulk as needed to stop air leaks.
Solar Panels have their place, BUT you need a lot of OTHER parts to use them, and their efficiency is currently too low to make them cost effective for most people in a non-commercial use.
To operate PROPERLY, a wind generator, NOT wind mill, MUST be a minimum of 20 feet HIGHER than any nearby trees or structures AND you must have fairly steady and heavy winds to produce enough power to make it cost efficient. It ALSO requires many additional parts.
