- dark colors attract heat and are the best for winter or cold times
- more coats of paint can also attract heat
- light colors are ideal for summer because they don't attract too much heat
You also need to change your painting ideas if you live in a regularly hot or cold area. Obviously, if you are normally very hot, then dark colors will hinder you more than they will help you. This makes normally cold areas perfect for dark colors because the heat isn't really a problem.
One last thing you need to keep in mind is that your home may have a very specific color that makes it unique, so you don't want to change your entire house's design and style just to be more energy efficient.
Wind energy is similar to energy from water. When water or wind moves fast enough it creates kinetic energy. That makes the turbines move and then it generates electricity. Then the turbines store that energy for later use. To understand wind energy you also need to understand wind. Wind is created when the sun heats up the ground. Then the warm air around it rises and mixes with the cooler air to create wind.

Some people change their lightbulbs when they get the slightest bit dim or really dim. This is bad. If you just dust off your lights, you will get more time and save more energy and more lightbulbs, glass, and other pollution/other harmful things.
