Thinking about doing a little landscaping around your house?  According to the U.S. Department of Energy, well placed trees, trellises and vines can add up to significant energy savings (up to 25%).

The DOE says that planting deciduous trees, (trees that lose their leaves in the fall) on the south and west sides of your house will provide shade to your house in the summer to help keep it cool.  As the weather gets colder, the trees will lose their leaves, allowing the sun to shine into your house and keep it warmer.
