Consider a solar powered attic fan if you are not ready to make the full switch to solar energy. This type of fan features sensors that can turn on the fan at a certain temperature. This will remove heat and lower the cost of cooling. A good solar powered attic fan will help cool your house and not cost anything to run.

When using solar energy for the first time, it's probably a good idea to start out small. A small investment of just a few solar powered garden lights is a great way to get started. You can find them at big box and even home improvement stores. They are as easy to install as any other garden light.
Solar power could benefit you, even if you live in a region that sees a lot of clouds year-round. Many people are under the misconception that solar energy is only useful in areas that see a lot of sun. The current technology actually can use the energy that penetrates the clouds to power your home.
