Having a home that is energy-efficient is great. Not only does it greatly help out the environment in many different ways, but it also saves you money in the long run.
Making your home more energy-efficient doesn't have to cost an arm and a leg. The nice thing is that you can pick different features that make your home run more efficiently. You do not have to do a complete remodel, but instead maybe consider investing in a low-flow sink head for the kitchen. These use 32% less water than regular ones, meaning less water waste, and less money spent on your water bill.
A lot of these updated efficiency features don't even require you to really do anything aside from the initial install. If you get a programmable thermostat, all you have to do is set it up. Then the thermostat will adjust itself based on the programmed settings to change the temperature of the house for you based on the time of day or year. This sounds expensive, but it can save you 10% per year on your electric bill!
These changes aren't just to help the environment. By making a simple change, like to LED light bulbs, your bulbs will last around eight times longer than traditional bulbs–and they'll use a quarter of the energy! That means they won't need to be replaced as often and they'll shave some money off that electric bill.
