Typical pop ecology drivel, used to fill space and keep writers from having to work or think.
1. Paint Your Roof White
Works in sunny climates, and I agree it extends the life of a roof
somewhat BUT... The bigger issue with roof life is the effect on it from ultraviolet. Paint would help more from shielding a roof from ultraviolet than from the heat buildup, which means unless you are painting shingles or roll roofing, the extended life argument is bogus. I started out arguing the other side of that argument (outgassing is more important) but came around to realizing I was wrong. AND... A white roof will have minimal temperature impact IF the attic is properly insulated (which is not mentioned).
2. Install an Irrigation Meter
Not having to pay for water, I save even more.
We had a well for irrigation water in Florida. I'd revise this to "stay off municipal systems as much as possible - save rainwater if you can."
3. Do a Nightly Energy Sweep..."It takes about $9 per year to run just one compact fluorescent lightbulb through the night" Really? Do the math. Around here a 23 watt lamp (100 watt equiv) for 9 hours costs for 365 days is about $7.50. A 13 watt lamp (more common) is much less. The idea is fine, generalizations iffy.
4. Set Your Water Heater at 120 Degrees.
This is flat out wrong. I've gone over the flaws in the reasoning so many times that I refuse to do so again. It is urban myth.
5. Use Reusable AC and Furnace Filters
I've used hogshair and expanded aluminum filters. They don't work well at all compared to the disposables. An electronic one is expensive. I've seen more neglected permanent filters than disposable ones. Cleaning a permanent one is messy and gets put off. Systems suffer because of that.
6. Upgrade Your Appliances
"Upgrade?" to save money? How about "replace?" The curve is leveling out on this anyway. The existing refrigerators are likely by now to be recent enough that the gains are minimal. And other appliances like ovens? Not a problem anyway.
7. Don't Let Cash Slip Through the Cracks
Probably the best bit of advice in the article.
8. Do Your Meter and Utility Bill Match Up?
"If the amount on your meter is lower than the one on your bill, that's a dead giveaway that you're being overcharged. " This "money saving" tip is SO idiotic that it incited me to respond to the other points as well. Look. The meter goes in one direction. It gets read every month. The meter reader makes an error one month, it gets re-read the next one and the error gets corrected. The only way you might save money is if your power company has a punitive tiered system of rates and you hit the next rate category. What an IDIOTIC "tip"!
9. Buy Energy-Star Certified Products
Buy to save. My old girlfriend used to do that all the time. Don't buy. Save even more!
10. Buy a Programmable Thermostat
Over-rated and only work in some situations. May end up COSTING money in others, especially if improperly programmed and a heat pump is involved.
Like I said, junk filler.
