Hole-In-One (Bill)

s2042I’ve been busy, literally digging into stuff.  The morons who built my house screwed up, so heavy rains gave me a wet basement.  By digging, I’ve been able to seriously whack my electric bill, saving ridiculous amounts of Watts.

More explanation: the property was not graded properly.  A house is supposed to be surrounded by a mild slope, causing rain to run off away from the foundation (and any basement if present).  Failure to grade leads to a damp basement, and in extreme cases foundation damage or settling.  My basement was damp in general, and certainly after serious rains, so I decided to take matters into my own hands.

I’ve been digging for months now, adding drainage features.  Then I threw the spoil toward my walls, to alter slopes.  I’m not even finished, and already I’ve been able to turn off the dehumidifier in the basement.  Without it, the electric bill fell sharply.  The first month, I didn’t pay attention much.  The second month was a coincidence.  The third month, however, showed me the dehumidifier had been the one biggest energy use in the house, since my electric bill is now half.  Yes, half.  Just digging cut my electricity use in half, and my EV is now “paid off” (in wattage terms) several times over.

I have to retract that first part: the general contractors for the house weren’t morons.  They aren’t paying the monthly utility bills, I am.  So what do they care if they “screwed up”?  Someone bought the new house, so for a builder, they succeeded.  Succeeded in suckering at least one homebuyer.  I, a later owner, am a sucker no more, and not an energy sucker.  Which makes me wonder: how many screwups are there, in this land of detached houses, and how many are simply being covered up by energy sucking?

4 Light Bulbs: One BIG Bulb

I’ve written a lot about canceling an EV’s electric usage, via (surprisingly few) “nega-watts”: electricity saved elsewhere.  I’ve mentioned lighting so far.  LED lamps use under a quarter of incandescents’ power- more like a fifth or sixth, meaning they even save over fluorescents.  I also mentioned these nega-watts then cut air conditioning too, since wasted bulb energy turns into heat.

Well, let’s go ahead and stake that vampire good, shall we?  One cannot discuss power savings, and the grid in general, without tackling the A/C question.  What shall we do with the one biggest load in the house, and most businesses too?  Grid load is driven by the hottest days’ A/C load, by definition.  Utilities plan on the max expected A/C usage, then upgrade their network to match.  Anyone with the grid in mind must plan on hot summer afternoons, too.

702fI know what I’ll do about A/C: the rest of my plan.  The last time I needed roof work, I got the lightest shade the company had.  I’ve bought new windows and more insulation, to put in my attic and walls; I’m about to buy even more.  My utility has their own initiatives: subsidies for efficiency, and for A/C budgeting.  In the future, I may nail that coffin once and for all.  I’m looking into a ground heat pump, drastically more efficient than plain ol’ air conditioners.

The Re-Fire Strikes Back

Cree 4flow LED lampAgain, welcome to 2015.  And a happy 2015 it is, at least in energy.  Not only have LED lamps fallen in price drastically from just a few years ago, but they continue to improve, in multiple respects.  Cree, one of the bigger names in LEDs, didn’t just release their groundbreaking lamp about a year ago.  They’re now on their generation-2 product, and yes, competition has improved the breed.

I’ve just installed Cree’s “4flow” LED lamp.  I bought this standard Edison base (“A19”) in 40-Watt equivalent.  Actual consumption is 6W, saving 34 nega-watts, or 85% less than an incandescent bulb of the same light output.  That’s also a savings over a compact fluorescent, though far less.  The big trick is getting rid of incandescents, which have only a few percent light efficacy.  The other ~97% of the electricity you put in is wasted as heat.  Basically, incandescents are little heaters that, oh by the way, make some light too.  But unlike fluorescents, LEDs turn on instantly.  They’re vibration, cold, and cycling resistant.  Their lives aren’t shortened by on-off cycles, such as bathroom and hallway installations.  Nor do they contain any mercury, though the mercury level of CFLs has been exaggerated.

I’ll Give Them Credit

Out with the old...

Out with the old…

...in with the new!

…in with the new!

Again, almost 2015.  My bank tossed their old bulbs and installed LEDs because… they’re a bank, and it’s almost 2015.  Obsolete lighting technology wastes energy, and thus money.  LEDs make money, as banks are supposed to do- certainly any bank of mine. Continue reading

4 Light Bulb… Snore

I just bought… an incandescent bulb!  Oh wait, weren’t they banned?  The exemption list is long:441z

  • Anything under 40 Watts
  • Anything over 100 Watts
  • Appliance (fridge/stove) bulbs
  • 3-Way bulbs
  • Candelabra bulbs, reflector (“silver end”) bulbs
  • Infrared-specific lamps
  • Rugged (vibration, shatterproof) bulbs
  • Colored lamps, plant lamps, “black lights” and “bug lights”
  • Tube bulbs (T-type) over 10″ long
  • Most types of stage lighting
  • Plus several more…

Not to mention stores are still selling “new old stock.”  One could argue the so-called “incandescent ban” is, in effect, a test of reading comprehension. Continue reading

Philips Followthrough: SlimNotShady

That was fast… Philips said they would respond to Cree’s sub-$10 40W-equivalent LED.  Their initial model was competitive, but didn’t push the technology or price point forward.  Philips had then shown test units of their newer LED design to reviewers, but the final price had yet to be announced by them and retailer Home Depot.s6

Now in the new year, Philips’ SlimStyle 60W-incandescent equivalent (10.5W actual), below $10, puts the ball squarely in Cree’s court.  Cree’s “60W” LED is ~$13 before rebates.  This broke the $10 barrier in 60W, the biggest seller in the US.  Rebates will almost certainly cut that further.  So far, it seems to be online only; no store by me had any.  It also seems units will hit shelves soon, maybe in days.  The warranty’s 3 years, in a 25,000 hr life claim.  For three years, at these savings, it makes sense even if it dies the day after the warranty expires.  So I might drop $10, get 49.5 negawatts, and give you my opinion.  Can’t lose as long as I have my receipt.

The future is here, folks.  Some people still insist on being stuck in the past.

4 Light Bulbs… Philips Followup

When Cree dropped a bombshell in March (a sub-$10 LED lamp), Philips had to respond.  They promised it by the end of the year.  It didn’t quite break the $10 barrier, sure.  An instant rebate now got me an 8 Watt LED (40W in incandescents) for 37djust under that mental barrier.  $10 now got me 32 more negawatts.

Who doesn’t like the Energy Independence and Security Act of 2007?  People who can’t do math.  Idiots who don’t get TCO (Total Cost of Ownership).  The LED’s about $9 more than an incandescent, sure.  But it’s built for a 20,000+ hour life, versus ~1000 hr incandescents.  You’d buy ~$19 in new bulbs versus one LED.  Meanwhile, at 8W you save $4.20 a year vs. 40W incandescents (assuming 3 hrs a day, at the US average 12¢ a kW-hour).  Thus, power-bill savings alone will pay off sometime in year 3.  Will pay off- the warranty is 6 years.

It’s a no-brainer, folks.  Now combine its power savings with no replacements, and in its 6 years, it saves over 30 bucks- $6.50 in replacements, $25.20 in juice. Continue reading
