old refrigerator

Dumping the Old Fridge is Greener than Installing Solar Panels

Let's face it. The greenest things you can do for your house and the planet fall a little short in the WOW Factor. Old refrigerators and freezers, and by that I mean almost any model from before 2000, are energy wasters compared to today's most efficient models. Dollar for dollar the best thing you can do for your house is to buy new refrigerators and freezers that use substantially less energy. Payback on a new machine can be as little as two years and most local utilities offer some sort of rebate or upgrade program to encourage their consumers to get a newer model. The government has some useful information about the Energy Star program

The second half of the green refrigeration solution is to make sure your old model gets recycled...and I don't mean the garage to keep your sodas cold, either. If you absolutely, positively want your sodas cold, buy a new refrigerator for the garage or rec room. Your old one, whether it's in the kitchen or the garage, is an energy pig. Modern recycling will safely remove the Freon or other refrigerant and send the steel off to to be made into something new and shiny. You can send it away knowing it will have a rich and worthwhile second life. Don't forget to keep your magnets.

bad flex duct connectionThe Joy of Attic Crawling

If the boring wisdom of getting a new refrigerator can't get your green gene fired up, how about a nice crawl through the attic or subfloor? It's very likely that as much as 20% of your heating and air conditioning dollar is being spent to heat and cool parts of your house you don't live in. Improperly sealed ducts, bad connections, and lack of insulation are major sources of wasted energy.

The good news is that I'm not going to ask you to crawl through scratchy fiberglass in your own attic. No, you get to hire a duct cleaning and repair specialist who can bring specialized equipment to clean and pressure test your system. Sadly, there's nothing glamorous left on your roof to show your neighbors you are Greener Than They Are. Maybe later.

Finally, the big bucks to show up the neighbors

Sorry. I feel like the Green Scrooge. You came for hot and sexy green-ness, and all I have for you is warm lime sherbet. I've already walked you through a new refrigerator and some duct repairs. Next on the cost efficiency list wouldn't normally be shiny new photovoltaics or a roof top wind turbine, but attic insulation, dual glazed windows, and weatherstripping instead. Still, it's my post and I'm going to skip that smart stuff and give you a chance to beat the neighbors to have the first photovoltaic installation on the block.

solar attic fan

For around $600 installed, you can have a simple, cost-effective, energy saving, building-preserving, roof-extending, moisture reducing solar attic fan. It's a great way to introduce yourself to solar energy, do your house a favor, and have a small touch of one-upmanship in your neighborhood. They work from morning until night all year around helping to keep your attic air circulating. It will help keep your house cooler in the summer and help prevent moisture accumulation in the winter.

Three Green Cool Suggestions

These three green ideas aren't as HOT as some newer comprehensive strategies for sustainability. What they have in common is modest price tags that the average home owner can fit into their long term green budget. Each of them can be accomplished for under $1,000 and typically in one day. Going green can be fast, affordable, and create great long term savings. In my book, that's sexy enough.

Dave - These are great ideas - I think a lot of people bypass the basics like sealing their doors and jump straight to water barrels and solar panels. I am certainly guilty of waiting far too long to replace/upgrade the basement door which is a major source of heat loss in our house.

Sara, for me it's the warped front door that lets cold air blow around the weather stripping and all the way to the back of the house. I'm as guilty as anyone for letting the small things go.

Cindy, whole house fans tend to be in the 400 watt range, so it could definitely be solar powered. I don't know of any ready made units that include solar, however, so it would probably be a more expensive installation that would make sense if you were doing a larger photovoltaic array for more than just a fan. The other drawback is that the whole house fan is most useful when the day is starting to cool off and temperatures fall to around 85 degrees or lower. At that point, you may not being generating any power from your solar system since the peak times for solar are two to four hours on either side of solar noon. A solar powered system with a whole house fan it would probably be to forget inverters (to convert to 120 volt power) and just stay with a 12 volt system. I would design and size it to charge a deep discharge battery to run a 12 volt whole house fan for as much time as the battery would provide a charge. A system like that could cost right around $1,000 and would have great cooling power as the air dropped in temperature.  The nice thing about your suggestion is that the whole house fan would mainly be needed on days when there was plenty of solar power to get the attic hot.

Hi Dave - I love the title of your post as it shows you can do things green without them costing a lot of green!  I'll have to give thought to the old frig I have in my basment keeping things cold and frozen for me.  I've often wondered if that thing was using a lot of electricity, and now that I've read what you've written, it just might be!

Thanks for these great tips - I could use ideas like this for my own house!

Dave, great post. That is interesting about the solar attic fan. I am going to check into that. Thanks for the tip.
4:21pm • #12

All true.  I had someone me recently about "what would the energy savings be if I replaced the hot water heater with a solar one?"  My questions back to them were "do you have an insulating blanket around the existing hot water heater?" and "have you put the hot water heater on a timer so its turned off when you're not around the house to use hot water?". The answer to both questions was "no".

Gee, sometimes the simplest things are great places to start.  I'd rather put on an insulating blanket and install a time for (at most) a couple of hundred bucks than to have someone tearing up my roof and spending thousands (even after the tax breaks) on a solar hot water heater.  Now when the hot water heater is worn out and its time to replace it, that's a different story.

Of course, I gave this advice to a number of people BEFORE I bought my own insulating blanket and timer and now our local Home Depot is sold out...darn.

Many things that are great ideas for the mainland don't apply here in Hawaii (ceiling insulation, heating ducts -- what are those?), but the advice of "start with the basics" definitely applies.

Dave:  Great post for energy and $$$$$$ saving ideas.  Another which is so remarkable (but expensive) would not only save energy but water, although expensive.  The Tankless Water Heater, now that's just short of remarkable, hopefully as they become more common they will be more economical.  Do you know of any special rebate program on this?  I love the solar attic fax, sound cool to me.  Patti - California

Thanks everyone, for your kind words. I always have to remind myself how simple things can add up to a big effort. Ben Franklin must have been the original inspiration with his "watch your pennies, the dollars will take of themselves" saying, but your comments here about everything from basement doors to water heater blankets let me know we have a lot of "bens" rattling around in ActiveRain. For those of you from Florida and Texas who mentioned the solar attic fans, all I can tell you is that they can really help keep your attic cooler and they work better the sunnier it gets.

Great post but something caught my attention and it was primarily your headline - > "Dumping the Old Fridge is Greener then Installing Solar Panels."

How could it be greener then solar panels when all factors are considered? (Trust me, I don't doubt the need to replace anything not energy star certified when the opportunity exists.)

Good information Dave. All affordable, unless we're replacing the old ice box with a Sub Zero. We don't have them up here at the lake, but we grew up in an old home with an attic fan. Made a lot of noise, that I can still hear fondly in my head.

Diane, we wouldn't be human if we didn't wait until the last minute to deal with problems. I think the future can properly blame us if we don't deal with energy and climate change now. It really is the last minute when you think about how long it takes to turn things around at the planetary scale. Each of us is an important contributor to either fixing things or making them worse.

Esko, the climate in Las Vegas is perfect for the solar attic fan. I don't know if you saw the latest Scientific American article about solar energy, but the authors are calling for thousand of square miles of Nevada, Arizona and California to produce all the energy for the United States by use of solar by the year 2100. You definitely have the sunshine for it.

Good tips. It really is about saving green and going green! Forget all those expensive fancy-schmancy improvements... If you can do it on the cheap, then do it on the cheap because in the end, you are probably saving resources as well as money and THAT is what green is all about.

Chip,

Because these are self-contained (no electrical hookup needed), the natural choice to install one is probably a roofer.

I don't know if anyone has noticed, but I saw these on sale at Costco for under $400 a few days ago.

would it do better than the 10 or more regular square vents you could get for that price, that work 24\7 and dont have moving parts that WILL eventually fail??Sorry but I am a new construction analyst, and if you figure cost/savings in the long run, standard metal roof vents spread properly offer better coverage against trapped air and has a better cost/savings ratio due to the lifespan of your vent. You can add radiant barrier for the cost of 2 of those fans. Bring you insulation to r-42+  for the same depending.... 

Heres a question
7:44pm • #65

somebody needs to mention the fact  whole house fans in the ceiling waste much more than they could ever save!!!! They leak air 24/7 365, have no r-value compared to the average required r-38.  Do you know how many portable or ceiling fans you can run with 400watts! Sealing your house is so cheap and so important, start by getting rid of your big loud eyesoar wholehouse fan. I wish i could show you some of my thermal pictures, those fans are bad news. Put them in your garage ceiling or recycle them.

8:00pm • #66

Here and also:

Thanks for your comments.  I stand by my original post, but I welcome your thoughtful and well informed comments. Let me address some of our areas of agreement.

1. I agree that moving parts will fail.

2. I agree that un-insulated whole house fans make a huge gap in the insulation barrier the house needs.

3. I agree that super-insulation (R-42 and up) can be useful.

As to where we disagree:

1. Ten square vents or any traditional venting (not commercial style roof vents) don't do the job. Sorry, but unless you go with continuous eave and continuous ridge vents combined, your attic is going to get hot.

2. You don't mention it, so I will. Moisture build up in attic spaces can be a major problem in many climates. The cost of replacing an entire roof deck because of mildew or rotted sheathing far outweights the cost of making sure ventilation is effective. Your new construction analysis has to include the potential for catastrophic failure of the roof membrane if moisture isn't addressed properly.

3. Radiant barriers are occasionally effective in uninsulated commercial spaces, but they are not the right solution for residential construction.

4. Whole house fans don't work in every climate. If your area doesn't cool off at night, a whole house fan doesn't provide much relief. In areas with hot days and cool nights a whole house fan is the preferred solution for cooling when compared to air conditioning. You talk about portable or ceiling fans and they do nothing to address the main source of heat build up in the house; the hot attic. Whole house fans directly cool that hot space. Can they be loud? yes. Can they be a heat lead if uninsulated? Certainly.

I think if push came to shove we would agree that homebuilders should:

1. Insulate at least to R-38

2. Use great vapor barriers to keep moisture out of the attic.

3. Use some highly effective method of air circulation in the attic. Whther a solar attic fan, mechanical vents, or large passive vents isn't my biggest concern. Making sure air circulates winter and summer alike is my concern.

Thanks for disagreeing with me. I love a good discussion with somebody who knows what they are talking about.
