In simple terms, a zero-energy house is one that produces as much energy as it uses. A worthy green goal, to be sure — and attaining a net-zero-energy home would also imply paying zero dollars on energy each month. Though going zero energy calls for a great deal of effort and planning, it’s something that may be accomplished by anyone. Join us as we investigate 10 ways you may start shifting your house toward zero-energy: Start with one or try them all, and provided that you will see your energy bills decreasing.

1. Install low-flow fixtures. Most low-flow showerheads and taps aerate water, which means you use less energy warming it. There’s often no requirement to replace an entire sink — the important part is the aerator (the screw-on hint of the tap), which determines maximum flow. This simple, cheap part could save a bundle on hot water expenses. Watch the hot water info page on the U.S. Department of Energy (DOE) site for more on this topic.

2. Switch off lights, computers and appliances. This simple habit doesn’t cost a dime and could make a major difference in your energy consumption, based on how consistent you’re. Teach kids along with other members of their family to stick to this principle: If nobody’s in the room, it doesn’t need to be on. In other words, shut off TVs, computers and lights before leaving a space, each and every time. It’s a custom that requires a little bit of diligence in the beginning but will become second nature.
3. Replace lightbulbs. Pick the newest energy-saving incandescent bulbs for an easy shift that will use 25% less energy than the older incandescent bulbs. To save even more energy, switch to compact fluorescent lamps (CFLs) or light-emitting diode (LED) bulbs, which use between 70 and 80 percent less energy than conventional incandescent bulbs. Be mindful that CFLs do contain a little bit of mercury, which means that they have to be recycled rather than thrown in the garbage. See the CFL info page on the U.S. Environmental Protection Agency’s (EPA’s) website for more information.

4. Increase insulation. The most critical source of air leaks in the house does not come from the drafts you are feeling, but from basements and attics, based on Energy Star. Find out how to track down and seal air leaks and improve insulation in the DIY guide available on the Energy Star website.
What is Energy Star? Energy Star is a joint program of the EPA and the DOE. Products that meet criteria set by both of these agencies may earn the Energy Star label.
5. Seal cracks and holes. Any deep holes or cracks in your home’s walls, ceiling or floors can be a possible source of air leaks. Investing just a couple of dollars in caulk and weatherstripping (or polyurethane sealant for larger gaps) is among the easiest and least expensive ways to boost your home’s energy efficiency. For more tips on sealing air leaks, visit the DOE’s website.

6. Replace an outdated AC system. With the summer months approaching, now is the best time to assess air-conditioning systems. If you’re installing or replacing central air, look for an Energy Star label with a seasonal energy-efficiency ratio (SEER) of 13 or higher, which is the newest standard, though older models are still being sold. New window air conditioners are almost two times as efficient as older ones, so springing for a brand new unit could reduce your house heating bill in half that summer. Look for an energy-efficiency ratio (EFR) of 10 or more for window AC units.
7. Replace (or alter) older windows. Single-pane windows are a major offender of heat loss during winter. Updating to low-U-value, low-E windows can save up to 25% of your heating bill, according to the DOE. If new windows aren’t in the cards, you may still improve efficiency by covering single-pane windows with storm windows in winter and white shades in summer to reflect heat away from the house.
8. Retrofit or replace your old furnace. The first step here is to test on the energy efficiency of your present furnace or boiler, which can be measured by yearly fuel-utilization efficiency (AFUE). Very old models had efficiencies in the 56 to 70 percent range, while the very best new furnaces measure up to 97% efficient. It’s possible to retrofit older boilers and boilers to boost energy efficiency, although the price should be weighed against the price of replacement and energy bill savings.

9. Pick Energy Star–rated appliances. When you are ready to buy a new refrigerator, washer or dishwasher, look for the Energy Star label to be certain you’re receiving an appliance that is up to the latest standards of energy efficiency. Watch more about this

10. Add a source of renewable energy. Remember, a zero-energy home needs to balance the energy used with energy generated. That means it is time to begin producing some of your personal energy! Installing solar panels (solar panels) is the best known option for homeowners today, though in certain areas you can actually choose to buy renewable energy from the regional power company.
Additional resources:Check the Database of State Incentives for Renewables & Efficiency to find out if your state provides financial incentives for installing solar panels or participating in additional renewable energy programs.
You might also have the ability to make the most of an energy-efficient mortgage or special financing for your home improvement projects; read more on this topic on the DOE website.
