Advantages of Solar Energy

In the wake of the greatest environmental disaster, here are some facts about solar energy.

Solar energy offers considerable advantages over conventional energy systems by nullifying flaws in those systems long considered to be unchangeable. Solar power for home energy production has its flaws, but they're dwarfed by the advantages listed below:

  1. Raw materials are renewable and unlimited. The amount of available solar energy is staggering, roughly 10,000 times that currently required by humans, and it's constantly replaced. A mere 0.02% of incoming sunlight, if captured correctly, would be sufficient to replace every other fuel source currently used by humans.
  2. Solar power is low-emission. Solar panels produce no pollution, although they impose environmental costs through manufacture and construction. These environmental tolls are negligible, however, when compared with the damage inflicted by conventional energy sources: the burning of fossil fuels releases roughly 21.3 billion metric tons of carbon dioxide into the atmosphere annually.
  3. Solar power is suitable for remote areas that are not connected to energy grids. It may come as a surprise to city-dwellers but, according to Home Power Magazine, as of 2006, 180,000 houses in the United States were off-grid, and that figure is likely considerably higher today. California, Colorado, Maine, Oregon, Vermont and Washington have long been refuges for such energy rebels, though people live off the grid in every state.
  4. Solar power provides green jobs. Production of solar panels for domestic use is becoming a growing source of employment in research, manufacture, sales and installation.
  5. In the long run, solar power is economical. Solar panels and installation are high initial expenses, but this cost is soon offset by savings on energy bills. Eventually, they may even produce a profit on their use.
  6. Solar power can mean government tax credits. U.S. federal subsidies credit up to 30% of system costs, and each state offers its own incentives. California, blessed with abundant sunshine, and plagued by high electric rates and an over-taxed grid, was the first state to offer generous renewable-energy incentives for homes and businesses.
  7. Solar power is reliable. Many homeowners favor solar energy because it is virtually immune to potential failings of utility companies, mainly in the form of political or economic turmoil, terrorism, natural disasters, or blackouts due to overuse.
  8. Solar power conserves foreign expenditure. In many countries, a large percentage of earnings is used to pay for imported oil for power generation. The United States alone spends $13 million per hour on oil, much of which comes from Persian Gulf nations. As oil supplies dwindle and prices rise in this politically unstable region, these problems continue to catalyze the expansion of solar power and other alternative-energy systems.

Top 10 Ways to Save Energy continued

And finally the moment we have all been waiting for (drum roll)

1. Find better ways to heat and cool your house.
As much as half of the energy used in homes goes toward heating and cooling. The following are a few ways that energy bills can be reduced through adjustments to the heating and cooling systems:
Install a ceiling fan. Ceiling fans can be used in place of air conditioners, which require a large amount of energy.
Periodically replace air filters in air conditioners and heaters (every 3 months)
Set thermostats to an appropriate temperature. Specifically, they should be turned down at night and when no one is home. In most homes, about 2% of the heating bill will be saved for each degree that the thermostat is lowered for at least eight hours each day. Turning down the thermostat from 75° F to 70°F, for example, saves about 10% on heating costs.
Install a programmable thermostat. A programmable thermostat saves money by allowing heating and cooling appliances to be automatically turned down during times that no one is home and at night. Programmable thermostats contain no mercury and, in some climate zones, can save up to $150 per year in energy costs.
Install a wood stove or a pellet stove. These are more efficient sources of heat than furnaces.
At night, curtains drawn over windows will better insulate the room.

2. Install a tankless water heater.

Demand water heaters (tankless or instantaneous) provide hot water only as it is needed. They don't produce the standby energy losses associated with storage water heaters, which will save on energy costs. Demand water heaters heat water directly without the use of a storage tank. Therefore, they avoid the standby heat losses required by traditional storage water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, demand water heaters deliver a constant supply of hot water. You don't need to wait for a storage tank to fill up with enough hot water.

3. Replace incandescent lights.

The average household dedicates 11% of its energy budget to lighting. Traditional incandescent lights convert approximately only 10% of the energy they consume into light, while the rest becomes heat. The use of new lighting technologies, such as light-emitting diodes (LEDs) and compact fluorescent lamps (CFL), can reduce energy use required by lighting by 50% to 75%. Advances in lighting controls offer further energy savings by reducing the amount of time lights are on but not being used. Here are some facts about CFLs and LEDs:

  • CFLs use 75% less energy and last about 10 times longer than traditional incandescent bulbs.
  • LEDs last even longer than CFLs and consume less energy.
  • LEDs have no moving parts and, unlike CFLs, they contain no mercury.

4. Seal and insulate your home.

Sealing and insulating your home is one of the most cost-effective ways to make a home more comfortable and energy efficient -– and you can do it yourself. A tightly sealed home can improve comfort and indoor air quality while reducing utility bills. An energy auditor can be hired to assess envelope leakage and recommend fixes that will dramatically increase comfort and energy savings.

The following are some common places where leakage may occur:

  • electrical outlets;
  • mail slots;
  • around pipes and wires;
  • wall- or window-mounted air conditioners;
  • attic hatches;
  • fireplace dampers;
  • weatherstripping around doors;
  • baseboards;
  • window frames; and
  • switch plates.

Because hot air rises, air leaks are most likely to occur in the attic. Homeowners can perform a variety of repairs and maintenance to their attics that save them money on cooling and heating, such as:

  • Plug the large holes. Locations in the attic where leakage is most likely to be the greatest are where walls meet the attic floor, behind and under attic knee walls, and in dropped-ceiling areas.
  • Seal the small holes. You can easily do this by looking for areas where the insulation is darkened. Darkened insulation is a result of dusty interior air being filtered by insulation before leaking through small holes in the building envelope. In cold weather, you may see frosty areas in the insulation caused by warm, moist air condensing and then freezing as it hits the cold attic air. In warmer weather, you’ll find water staining in these same areas. Use expanding foam or caulk to seal the openings around plumbing vent pipes and electrical wires. Cover the areas with insulation after the caulk is dry.
  • Seal up the attic access panel with weatherstripping. You can cut a piece of fiberglass or rigid foam board insulation the same size as the attic hatch and glue it to the back of the attic access panel. If you have pull-down attic stairs or an attic door, these should be sealed in a similar manner.

5. Install efficient shower heads and toilets.

The following systems can be installed to conserve water usage in homes:

  • Low-flow shower heads. They are available in different flow rates, and some have a pause button which shuts off the water while the bather lathers up;
  • Low-flow toilets. Toilets consume 30% to 40% of the total water used in homes, making them the biggest water users. Replacing an older 3.5-gallon toilet with a modern, low-flow 1.6-gallon toilet can reduce usage an average of two gallons-per-flush (GPF), saving 12,000 gallons of water per year. Low-flow toilets usually have "1.6 GPF" marked on the bowl behind the seat or inside the tank;
  • Vacuum-assist toilets. These types of toilets have a vacuum chamber which uses a siphon action to suck air from the trap beneath the bowl, allowing it to quickly fill with water to clear waste. Vacuum toilets are relatively quiet; and
  • Dual-flush toilets. Dual-flush toilets have been used in Europe and Australia for years, and are now gaining in popularity in the U.S. Dual-flush toilets let you choose between a 1-gallon (or less) flush for liquid waste, and a 1.6-gallon flush for solid waste. Dual-flush 1.6-GPF toilets reduce water consumption by an additional 30%.

6. Use appliances and electronics responsibly.

Appliances and electronics account for about 20% of household energy bills in a typical U.S. home. The following are tips that will reduce the required energy of electronics and appliances:

  • Refrigerators and freezers should not be located near the stove, dishwasher or heat vents, or exposed to direct sunlight. Exposure to warm areas will force them to use more energy to remain cool.
  • Computers should be shut off when not in use. If unattended computers must be left on, their monitors should be shut off. According to some studies, computers account for approximately 3% of all energy consumption in the United States.
  • Use efficient “Energy Star”-rated appliances and electronics. These devices, approved by the DOE and the EPA’s Energy Star Program, include TVs, home theater systems, DVD players, CD players, receivers, speakers and more. According to the EPA, if just 10% of homes used energy-efficient appliances, it would reduce carbon emissions by the equivalent of 1.7 million acres of trees.
  • Chargers, such as those for laptops and cell phones, consume energy when they are plugged in. When they are not connected to electronics, chargers should be unplugged.
  • Laptop computers consume considerably less electricity than desktop computers.

7. Install daylighting as an alternative to electrical lighting.

Daylighting is the practice of using natural light to illuminate the home's interior. It can be achieved using the following approaches:

  • Skylights, it is important that they be double-pane or they may not be cost-effective. Flashing skylights correctly is key to avoiding leaks;
  • Light shelves, light shelves are passive devices designed to bounce light deep into a building. They may be interior or exterior. Light shelves can introduce light into a space up to 2½ times the distance from the floor to the top of the window, and advanced light shelves may introduce four times that amount;
  • Clerestory windows, clerestory windows are short, wide windows set high on the wall. Protected from the summer sun by the roof overhang, they allow winter sun to shine through for natural lighting and warmth; and
  • Light tubes, light tubes use a special lens designed to amplify low-level light and reduce light intensity from the midday sun. Sunlight is channeled through a tube coated with a highly reflective material, then enters the living space through a diffuser designed to distribute light evenly.

8. Insulate windows and doors.

About one-third of the home's total heat loss usually occurs through windows and doors. The following are ways to reduce energy lost through windows and doors:

  • Seal all window edges and cracks with rope caulk. This is the cheapest and simplest option.
  • Windows can be weatherstripped with a special lining that is inserted between the window and the frame. For doors, weatherstrip around the whole perimeter to ensure a tight seal when closed. Install quality door sweeps on the bottom of the doors, if they aren't already in place.
  • Install storm windows at windows with only single panes. A removable glass frame can be installed over an existing window.
  • If existing windows have rotted or damaged wood, cracked glass, missing putty, poorly fitting sashes, or locks that don't work, they should be repaired or replaced.

9. Cook smart.

An enormous amount of energy is wasted while cooking. The following recommendations and statistics illustrate less wasteful ways of cooking:

  • Convection ovens are more efficient that conventional ovens. They use fans to force hot air to circulate more evenly, thereby allowing food to be cooked at a lower temperature. Convection ovens use approximately 20% less electricity than conventional ovens.
  • Microwave ovens consume approximately 80% less energy than conventional ovens.
  • Pans should be placed on the correctly-sized heating element or flame.
  • Lids make food heat more quickly than pans that do not have lids.
  • Pressure cookers reduce cooking time dramatically.
  • When using conventional ovens, food should be placed on the top rack. The top rack is hotter and will cook food faster.

Top 10 Ways to Save Energy

Why make your home more energy efficient? Here are a few good reasons:

  • Federal, state, utility and local jurisdictions' financial incentives, such as tax breaks, are very advantageous in most parts of the U.S.
  • It saves money. It costs less to power a home that has been converted to be more energy-efficient.
  • It increases indoor comfort levels.
  • It reduces our impact on climate change. Many scientists now believe that excessive energy consumption contributes significantly to global warming.
  • It reduces pollution. Conventional power production introduces pollutants that find their way into the air, soil and water supplies.

Here we go:

10. Change the way you wash your clothes.

  • Do not use the “half load” setting on your washer. Wait until you have a full load of clothes, as the “half load” setting saves less than half of the water and energy.
  • Avoid using high-temperature settings when clothes are not that dirty. Water that is 140 degrees uses far more energy than 103 degrees for a "warm" setting, but 140 degrees isn’t that much better for washing purposes.
  • Clean the lint trap before you use the dryer, every time. Not only is excess lint a fire hazard, but it will prolong the amount of time required for your clothes to dry.
  • If possible, air-dry your clothes on lines and racks.
  • Spin-dry or wring clothes out before putting them into a dryer.

    Electrical Safety continued

    • Routinely check your electrical appliances and wiring.
    • Frayed wiresires can cause fires. Replace all worn, old and damaged appliance cords immediately.
    • Use electrical extension cords wisely and don't overload them.
    • Keep electrical appliances away from wet floors and counters; pay special care to electrical appliances in the bathroom and kitchen.
    • Don't allow children to play with or around electrical appliances, such as space heaters, irons and hair dryers.
    • Keep clothes, curtains and other potentially combustible items at least 3 feet from all heaters.
    • If an appliance has a three-prong plug, use it only in a three-slot outlet. Never force it to fit into a two-slot outlet or extension cord.
    • Never overload extension cords or wall sockets. Immediately shut off, then professionally replace, light switches that are hot to the touch, as well as lights that flicker. Use safety closures to childproof electrical outlets.
    • Check your electrical tools regularly for signs of wear. If the cords are frayed or cracked, replace them. Replace any tool if it causes even small electrical shocks, overheats, shorts out or gives off smoke or sparks.

    Electrical Safety

    Electricity is an essential part of our lives. However, it has the potential to cause great harm. Electrical systems will function almost indefinitely, if properly installed and not overloaded or physically abused. Electrical fires in our homes claim the lives of 485 Americans each year and injure 2,305 more. Some of these fires are caused by electrical system failures and appliance defects, but many more are caused by the misuse and poor maintenance of electrical appliances, incorrectly installed wiring, and overloaded circuits and extension cords. Some safety tips to remember:

  • Never use anything but the proper fuse to protect a circuit.
  • Find and correct overloaded circuits.
  • Never place extension cords under rugs.
  • Outlets near water should be GFCI-type outlets.
  • Don't allow trees near power lines to be climbed.
  • Keep ladders, kites, equipment and anything else away from overhead power lines.

    Aluminum Wiring

    Between approximately 1965 and 1973, single-strand aluminum wiring was sometimes substituted for copper branch-circuit wiring in residential electrical systems due to the sudden escalating price of copper. After a decade of use by homeowners and electricians, inherent weaknesses were discovered in the metal that lead to its disuse as a branch wiring material. Although properly maintained aluminum wiring is acceptable, aluminum will generally become defective faster than copper due to certain qualities inherent in the metal. Neglected connections in outlets, switches and light fixtures containing aluminum wiring become increasingly dangerous over time. Poor connections cause wiring to overheat, creating a potential fire hazard. In addition, the presence of single-strand aluminum wiring may void a home’s insurance policies.
    Aluminum wiring should be evaluated by a qualified electrician who is experienced in evaluating and correcting aluminum wiring problems. Not all licensed electricians are properly trained to deal with defective aluminum wiring. The CPSC recommends the following two methods for correction for aluminum wiring:
    • Rewire the home with copper wire. While this is the most effective method, rewiring is expensive and impractical, in most cases.
    • Use copalum crimps. The crimp connector repair consists of attaching a piece of copper wire to the existing aluminum wire branch circuit with a specially designed metal sleeve and powered crimping tool. This special connector can be properly installed only with the matching AMP tool. An insulating sleeve is placed around the crimp connector to complete the repair. Although effective, they are expensive (typically around $50 per outlet, switch or light fixture).

    Garbage Disposals

    If a garbage disposal discharges into a septic tank, it can place significant strain on the septic system. The amount of waste that enters the tank, particularly grease and suspended solids, will increase considerably. This load increase requires that the septic tank be pumped more often than would otherwise be required. The additional strain will also reduce the life span of the septic system. Septic systems can be designed to accommodate food waste but, in general, they are not.

    Maintenance and Operation Suggestions:

    Put only small quantities of food into the disposal at a time. Large food scraps should be cut into smaller pieces before entering the disposal.

    Never put anything down the disposal that is not food or water. Bottle caps, aluminum foil, and other non-food items can damage the disposal or get stuck in piping.

    Run water while using the disposal, and for approximately 30 seconds after you turn it off. Food scraps will flow through the piping more easily if they are pushed along by water. Cold water is better than warm water for this purpose because it will force fats and grease to congeal and harden, allowing them to move more easily through pipes. Warm water can be run through the disposal while it is not in operation.

    Ice can be used to clear off solidified grease and other debris from the blades in a garbage disposal.The garbage disposal should only be used to grind non-fibrous, leftover food. If in doubt as to whether something can be put in the disposal, err on the side of caution and put it in the trash instead.

    The following items should never be put in a disposal:

    Items that are hard enough to dull the blades, such as shells from shellfish or bones;
    food that is highly fibrous, such as cornhusks, artichokes, pineapples, potato peels, asparagus, or celery should enter a disposal only in small quantities or avoided entirely. These foods take a long time to grind and can clog the disposal or the plumbing. Grease, household oils or chemicals should be avoided.
