SAVE ENERGY - SAVE MONEY

Greening Neighborhoods promotes, educates, and supports
neighborhood efforts to conserve our natural resources, save
money, and reduce dependency on nonrenewable resources

Blog

I thought it would be a good idea, being that we are beginning a new year, to review the categories of conservation that Greening Neighborhoods recommends for saving money, reducing unnecessary waste of our natural resources, and lowering our carbon footprint.

1)  First on the list, and the best way to save money, is by using alternative transportation.

 Take public transportation, ride our bikes for errands, car pool, and when we buy a new car get one  that  gets good mileage.  The average American drives 36 miles a day to and from  work.  By ride sharing with one other person we can save over $4,000 a year  on wear and  fuel.   We would reduce our yearly carbon footprint by 3,600 pounds of CO2.  Resource: Clean Air Campaign

 

2)  Reduce heating and cooling bills by insulating our attic, cutting off air leaks at doors, windows and pipe holes in the walls.

 Many contractors recommend 16 inches of fiberglass insulation, or R 50.  There are a number of  rebates  available for adding insulation.  Most neighbors who have added at least R 30 insulation  and have sealed air leaks have reported savings from 40 to 60% on their gas and electric bills.  Resource:  NRG SVRS  Resource:  Energy Conservation Solutions

 


3)  Reduce water consumption.  This is easy and inexpensive to do.

Low flow faucets and shower heads are inexpensive and can cut water use by 1/2 when they are installed.

For $20.00 kits are available at hardware and building supply stores to convert older toilets to water saving duel flush toilets.

 

 The 300 gallon water container in the background costs around $75 and will capture  roof  runoff for watering our gardens and lawns.  Most homes that water lawns and  gardens  using treated municipal water will double their water bills in summer months.  This water  is free.

An added bonus is by collecting rain water we reduce storm water runoff that enters our  sewers and causes  flooding and pollution.  Resource: lew@greeningneighborhoods.com

4)  We can lower our electric bills by switching to compact fluorescent light bulbs or LED lights.

 We can get into the habit of switching off lights when we leave the room.  If that technique  fails we can buy an inexpensive motion detector that does it for you.

We can set the water heater temperature to a lower level.  We can buy Energy Star  appliances that have the best ratings.

 

5)  Improve indoor air quality.

 We have abundant opportunities to buy toxic chemicals used in commercial cleaning  products, home repair building materials, and even cosmetics.  Federal labeling is  improving so we can see what’s in the products we buy.  To make sure we know what’s in  the  products we use, we can always make our own products like the window cleaner shown  here,  which is made from water, vinegar and a bit of liquid soap.  The benefits are not  immediate  savings, but future savings through lower health costs.  Resource:  Greening Neighborhoods

 

6)  Buy local, plant a garden.

 Meats and produce bought from farmers’ market are fresher, shipped locally, and the  money we spend stays in the local economy.

And, if the farmer markets are near by, we can walk to market.

7)  Recycle

 Recycling paper, plastic, metal waste means that is not waste at all, but raw material to be  used again.  It means that tons of materials are kept out of landfills reducing the release of  methane gas, a contributor to green house gases and global warming.

Resource: City of Atlanta

 

8)  Control solar heat gain

This can be done in a number of ways.  The least expensive is by adding a high quality film on the inside window face.  If it is in your budget replacement windows can be triple pane with the sun blocking film within the glazing itself.

When it time to replace shingles we need to get the kind that reflect sunlight (and heat) so we don’t have to spend extra money cooling the heat absorbed by dark colored shingles.  Resource: Greening Neighborhoods  Resource: Cool Roof Calculator

 

 

 

Greening Neighborhoods wishes you a healthy, prosperous, green new year.

 

If we set our thermostats back 1 degree for 8 hours we will save 1% of our heating bill.

Many of us like to sleep in cooler conditions, so by setting our thermostats back 10 to 15 degrees for 8 hours we will be rewarded with a good night’s sleep and savings of 10% on our yearly bill.  It is a common misconception that energy is wasted by turning down the thermostat that much and then heating the house back up to normal.  Not so.

To get accustomed to living a little cooler than what we’re used to, try backing into cooler living by lowering the temperature 1 degree for a week.  This will  give ourselves time to adjust to a new “normal” temperature.  Then try doing it again for the following week.

 

 

Winter is coming and the heat is being turned on. Every hole in exterior walls, including those for light switches, outlets, doors, windows and ceiling light fixtures, is an invitation for cold air to get in and heated air to get out. As much as 25 percent of your heating and cooling energy can be lost through these leaks. Put your hand in front of a light switch or outlet. If it feels colder than the wall around it insulation is required.  Light a candle and hold it near your door and window jambs. If the flame blows toward you cold air is getting in and weather stripping is required.  Look under the sink where the drain pipe enters the wall.  If it is not completely sealed warm air is escaping.

Fortunately, these fixes are inexpensive and easy to put in place.

Place insulation behind outlet plates
Add weather stripping

Add spray sealant

Cold weather is upon us.  The last thing we want to happen is for our outdoor faucets to freeze up causing pipes to burst and water to run wild inside our walls.  Here’s what you need to do to minimize potential problems:

1. Disconnect your hose from your outside faucet.
2. If you have a shutoff valve inside the house for the outside spigot, turn it off and then open the outside spigot to drain the water.
3. Go to your favorite hardware store and buy faucet covers and install them on all your outside spigots. They cost $1.00 at most stores.

 

It’s now possible to have lots of Christmas lights and much lower electricity consumption than before — all thanks to LED lights available everywhere.

LED’s come in every configuration imaginable, use 15% of the electricity of incandescent lights, and last a life time.  For those of us who want to save even more electricity we can now get solar powered LED lights.  Our neighbor, Betty Hanacek, got a couple of strings and reports that even on the north side of her house there is enough solar energy to light her front yard display from dusk until bed time.

Another green reminder is to recycle cardboard boxes and wrapping paper.  Better yet, reuse the wrapping paper next year and save some trees.

Have a Happy Holiday!

Last week we encouraged everyone to insulate our homes before the weather gets too bad.  It is the best way to reduce our utility bills and cut down on green house gas emissions.  On average heating and cooling amount to about 43% of our energy use.

 

 

 

 

 

 

 

 

 

There are two common ways to reduce those costs by insulation — Fiberglass batt insulation and closed cell spray insulation.  There are advantages and disadvantages to each.

Fiberglass is less expensive, but you need twice the thickness of fiberglass to get the same insulating value as spray insulation.

Fiberglass insulation can be put in place easier than closed cell spray insulation and, with a little care, can be a do-it-yourself project .  It can be laid between the ceiling joists in the attic.

The foam insulation is a two part process where two chemicals are mixed and sprayed on with special equipment.  There are do-it-yourself kits, but if it were me I’d hire a professional.

6 inches of spray insulation being applied

The foam insulation, when applied correctly, seals air leaks and is a vapor barrier.  It can be applied under the roof sheathing leaving the attic space insulated and usable for an additional room.  (Fiberglass insulation can be used to insulate between roof rafters rather than being laid between the ceiling joists, but it has only half the resistance to heat loss than spray.)

Six inches of spray insulation or 12 inches of fiberglass insulation will give us an R36 insulation value.  Either way our energy savings will be noticeable and we can feel good about reducing green house gas emissions.

Find out about Atlanta’s SHINE rebate program.

Find out about Decatur’s Wise rebate program.

Many of our neighborhood homes have little or no attic insulation.  Without adequate insulation half of our heating dollars rise up and out of the house in the winter.  During the summer, heat builds up in a poorly insulated attic to the point where we end up paying to cool the attic.

Insufficient Insulation

 

If there is less than 6 inches of insulation in your attic – and 6 inches is the minimum – you are paying more for winter heating than you should.  Many energy conscious builders are now recommending 16 inches of fiber glass batt insulation.

Last winter three of our neighbors insulated their attics and compared their February 2011 energy bills with those of February 2010.  Their savings were significant.

In Carolyn’s case a hole in her wall was discovered behind her refrigerator that was letting heat escape.  With the hole repaired and insulation added, her heating bill was reduced by 2/3.  For Jane and Dave, their bills were reduced by 1/3.

There are still rebates available for adding insulation.  In Atalanta check out the SHINE program http://www.atlantaga.gov/mayor/shine_080410.aspx.  In Decatur go to Decatur Wise http://www.decaturga.com/index.aspx?page=595.

Greening Neighborhoods encourages everyone to exchange traditional incandescent light bulbs for compact fluorescent lamps or LED’s because of the savings in the amount of electricity they use.  The one drawback in using fluorescent lamps is that the phosphorus lamp coating contains traces of mercury.  The amount of mercury is small, about 1/100 of that contained in the old mercury thermometers we used to have.  Still, indoor air quality is threatened if the lamps break and proper cleanup procedures aren’t followed.  The Environmental Protection Agency (EPA) recommends the following:

Before Cleanup

  • Have people and pets leave the room.
  • Air out the room for 5-10 minutes by opening a window or door to the outdoor environment.
  • Shut off the central forced air heating/air-conditioning system, if you have one.
  • Collect materials needed to clean up broken bulb (Don’t vacuum):
  • stiff paper or cardboard;
  • sticky tape;
  • damp paper towels or disposable wet wipes (for hard surfaces); and
  • a glass jar with a metal lid or a sealable plastic bag.

During Cleanup

  • Be thorough in collecting broken glass and visible powder.
  • Place cleanup materials in a sealable container.

After Cleanup

  • Promptly place all bulb debris and cleanup materials outdoors in a trash container or protected area until materials can be disposed of properly. Avoid leaving any bulb fragments or cleanup materials indoors.
  • If practical, continue to air out the room where the bulb was broken and leave the heating/air conditioning system shut off for several hours.

Getting Rid of Burned out Bulbs

Burned out lamps that are not broken should be taken to a recycling center.  Home Depot and Lowes have disposal bins for the old lamps.

How to Choose Low Energy Consuming Lights

Incandescent Bulb               Compact Fluorescent (CFL)          Light Emitting Diode (LED

       

       
Incandescent lights have been the standard for more than a hundred years.  The amount of energy they consume and their level of brightness are measured in watts.
Efficiency
Bulb Type      Efficiency (lumens/watt)
Incandescent                    10
Halogen                            16-20
LED                                     35
CFL                                     55
large fluorescents           94
Sodium Street Light      150

We have come to associate the amount of energy a standard light bulb uses in watts with the bulb’s brightness.   Brightness is measured in lumens.  For every Watt of power demanded by an incandescent bulb, 10 lumens are produced.  The same Watt produces 35 lumens in a white LED bulb and 55 lumens in a compact fluorescent bulb.  Therefore, LED’s and compact fluorescent bulbs are more efficient.

The following table illustrates the differences between the three types of lights having equal brightness..

COMPARE Incandescent 60 watt bulb CFL 13 watt bulb LED 8 watt bulb*
Life Span 1,000 hours 2,500 hours 30,000 hours
Bulb costs for 30,000 hrs $25.50(30 bulbs @ $0.85 ea) $60.00(12 bulbs @ $5.00 ea) $34.00 (1 bulb)
Cost of Electricity for 30,000 hrs** $206.46 $44.73 $25.81
Total Cost (bulb + electricity) $231.96 $104.76 $59.81
Hazardous Material? No Yes (Mercury) No
Cost to Run 12 hrs per day for 1 year $30.14 $6.53 $3.77

**Based on $0.1147 per kwh

We can keep our car looking beautiful AND save money! Taking our car to a professional carwash rather than washing it at home saves water and it saves money on our water/sewer bill. But not all car washes are created equal. Some make conservation a practice. The International Carwash Association keeps a list of member carwashes that meet the Association’s WaterSavers program guidelines. To learn more, go to http://www.washwithwatersavers.com. In Atlanta, Cactus Car Wash at 575 Ponce de Leon Ave. meets the ICA’s conservation requirements.
