7. Plant Trees Strategically

Your house gets hot because the sun beats down on it relentless on hot summer days. Let nature help reduce your energy bills by planting deciduous trees on the east and west sides of your home; in the summer, their broad leaves will shade your house, while in the winter, bare branches won't stop the sun's warmth from reaching your walls. Also consider planting trees or shrubs to shade high-heat areas – air conditioning units that emit heat, for instance, and driveways and walkways that absorb it. Of course, sitting under a shady tree on a hot summer day isn't a bad way to pass the time, wherever the tree stands!
