Remember, every little bit counts. Install and use a set back thermostat. Swap out conventional light bulbs for energy efficient compact fluorescent lighting. Plan your trips to the grocery store rather than running out, coming home and then running out again. Use your bicycle to run errands when you can. Keep an eye on solar systems and when you can install them on your home, do so. Unfortunately, the costs of these systems are so great that the payback is in many years. Hopefully, with the competition from the Chinese PV (photovoltaic) panel manufacturers will help to drive the prices down and allow more people to install these systems with a shorter payback of the system.
