Tips To Save Energy

Tips to Save Energy Today Sometimes you can’t power home from near free energy but you can always economize and be sensible. If you are so inclined, you can take your savings and purchase a manual and some equipment to make your energy free or at least,  almost free.So, without further ado, here are a few tips to help you on that road to saving:• Set your thermostat comfortably low in the winter and comfortably high in the summer. Install a   programmable thermostat that is compatible with your heating system.• Use compact fluorescent light bulbs.• Air dry dishes instead of using your dishwasher’s drying cycle.• Turn off your computer and monitor when not in use.• Plug home electronics, such as TVs and DVD players, into power strips; turn the power strips off when the equipment is not in use (TVs and DVDs in standby mode still use several watts of power).• Lower the thermostat on your hot water heater to 120° F.• Take short showers instead of baths.• Wash only full loads of dishes and clothes.•

Look for the ENERGY STAR® label on home appliances and products. ENERGY STAR products meet strict efficiency guidelines set by the U.S. Environmental Protection Agency and the U.S. Department of Energy.Your Homes Energy UseThe first step to taking a whole house energy efficiency approach is to find out which parts of your house use the most energy. A home energy audit will pinpoint those areas and suggest the most effective measures for cutting your energy costs. You can conduct a simple home energy audit yourself, you can contact your local utility, or you can call an independent energy auditor for a more comprehensive examination. For more information about home energy audits, including free tools and calculators,  Check the insulation levels in your attic, exterior and basement walls, ceilings, floors, and crawl spaces.• Check for holes or cracks around your walls, ceilings, windows, doors, light and plumbing fixtures, switches, and electrical outlets that can leak air into or out of your home.• Check for open fireplace dampers.• Make sure your appliances and heating and cooling systems are properly maintained. Check your owner’s manuals for the recommended maintenance.• Study your family’s lighting needs and use patterns, paying specialattention to high-use areas such as the living room, kitchen, and outside lighting. Look for ways to use lighting controls—like occupancy sensors, dimmers, or timers—to reduce lighting energy use, and replace standard (also called incandescent) light bulbs and fixtures with compact or standard fluorescent lamps.Formulating Your PlanAfter you have identified where your home is losing energy, assign priorities by asking yourself a few important questions:• How much money do you spend on energy?• Where are your greatest energy losses?• How long will it take for an investment in energy efficiency to pay for itself in energy cost savings?• Do the energy saving measures provide additional benefits that are important to you (for example, increased comfort from installing double-paned, efficient windows)?• How long do you plan to own your current home?• Can you do the job yourself or will you need to hire a contractor?• What is your budget and how much time do you have to spend on maintenance and repair?How We Use Energy in Our HomesHeating accounts for the biggest chunk of a typical utility bill.Once you assign priorities to your energy needs, you can form a whole house efficiency plan. Your plan will provide you with a strategy for making smart purchases and home improvements that maximize energy efficiency and save the most money.Another option is to get the advice of a professional. Many utilities conduct energy audits for free or for a small charge. For a fee, a professional contractor will analyze how well your home’s energy systems work together and compare the analysis to your utility bills. He or she will use a variety of equipment such as blower doors, infrared cameras, and surface thermometers to find leaks and drafts.After gathering information about your home, the contractor or auditor will give you a list of recommendations for cost effective energy improvements and enhanced comfort and safety. A good contractor will also calculate the return on your investment in high efficiencyequipment compared with standard equipment.Tips for Finding a Contractor• Ask neighbors and friends for recommendations• Look in the Yellow Pages• Focus on local companies• Look for licensed, insured contractors• Get three bids with details in writing• Ask about previous experience• Check references• Check with the Better Business BureauInsulationChecking your home’s insulation is one of the fastest and most cost efficient ways to use a whole house approach to reduce energy waste and make the most of your energy dollars. A good insulating system includes a combination of products and construction techniquesthat protect a home from outside temperatures—hot and cold, protect it against air leaks, and control moisture. You can increase the comfort of your home while reducing your heating and cooling needs by up to 30% by investing just a few hundred dollars in proper insulation and sealing air leaks.Where to InsulateAdding insulation in the areas shown below may be the best way to improve your home’s energy efficiency.Crawl spaceBasementAtticWallsFloorsFor customized insulation recommendations, visit energysavers.gov and check out the Zip Code Insulation Calculator, which lists the most economic insulation levels for your new or existing home based on your zip code and other basic information about your home.Although insulation can be made from a variety of materials, it usually comes in four types; each type has different characteristics.Rolls and batts—or blankets—are flexible products made from mineralfibers, such as fiberglass and rock wool. They are available in widths suited to standard spacings of wall studs and attic or floor joists.2×4 walls can hold R-13 or R-15 batts; 2×6 walls can have R-19or R-21 products.Loose-fill insulation—usually made of fiberglass, rock wool, orcellulose comes in shreds, granules, or nodules. These small particles should be blown into spaces using special pneumatic equipment. The blown-in material conforms readily to building cavities and attics. Therefore, loose-fill insulation is well suited for places where it is difficult to install other types of insulation.Rigid foam insulation—foam insulation typically is more expensive than fiber insulation. But it’s very effective in buildings with space limitations and where higher R-values are needed. Foam insulation R-values range from R-4 to R-6.5 per inch of thickness (2.54 cm), which is up to 2 times greater than most other insulating materials of the same thickness.Foam-in-place insulation—can be blown into walls and reduces air leakage.Mind you, if you’re able to power home from near free energy then you may not worry so much about energy conservation and insulation values. Although it would be prudent to and sensible to make sure your home is well sealed in either case.
