For those in hotter regions using solar energy to heat water would be an excellent method to save energy costs. The cooling unit of the split air-conditioner should be kept in a cool place that gets enough of air flow. Contrary to popular belief that a room must be installed with a larger than necessary air-conditioner power experts say that it is better that a smaller capacity machine is kept running for a longer time to ensure even cooling and lesser power consumption. A water heater blanket could be installed to get a saving of ten percent on the heating charges. The people who live in cold places could switch off the water heaters if they are not going to be at home for the next 10 hours. Insulating the water pipes and installing an automatic timer for the water heater is a pragmatic idea. Insulation of the home and using CFL bulbs instead of incandescent bulbs would cut down on lighting energy costs.
