Five Percent: Conserve a Little Energy

The Facts of Cap-and-Trade from Clean Energy Works on Vimeo.

Yep. It’s that simple.

A while back, I had started a project of insulating the heating pipes that run through my basement — we have an old house that was designed for a gravity-fed hot water heating system — iron pipes and big old radiators.

Unlike a modern system, using copper pipe that run through baseboard radiators, we have a system that appears to be one step beyond the old steam-heat systems: big, heavy cast-iron radiators that take up a lot of space; and big, heavy cast-iron piping that runs through the basement and upon which I regularly knock my noggin.

Insulating my pipes was, to use an indelicate expression, like pissing in the wind. Or at least it was then. Today, I finished that job. But it took 13 years — insulating my heating pipes was probably the only thing I did that I should have done last. But I am getting ahead of myself. (more…)

Can I, personally, make a difference in our attempts to reduce or mitigate climate change impacts? Or is this instead a problem that needs to be addressed through policy changes?

At a party last weekend, my friend Mike said he had just bought an electricity monitor based on my recommendation, and admitted it was a gift for his wife — he said that all of our little individual efforts add up to nothing significant. He didn’t really believe that personal action will affect things; his wife does.

I have written down my personal attempts to make change here in this blog, now in my fifth year. Much of what I have done involves making small changes that have indeed added up, so perhaps you might guess that I disagree with Mike’s view. Is it really true that all of the little things I have done add up to nothing?

Yes: the changes I have made add up to nothing.

Even our personal reduction of our energy consumption by almost one half of its former levels (probably more) over these years has resulted in a dramatic reduction of our impact, it means very little. The problem is that we need is to get the other several billions of people living in industrialized countries to make even modest changes. And our governments to concur and set in motion a new set of policies that lead us back to sustainable occupation of the planet.

So why bother making personal changes when a wasteful neighbor (not Mike) undoes our efforts five times over?

The answer lies in how big changes tend to happen. I see myself as part of a movement. I do what I can to make the movement progress.

Mike bought an electricity meter because I had one. Theresa and I have Prius’s now — we bought them to replace our older less efficient cars. We were the first on our street to have a Prius. But we told several neighbors and friends how much we like them (and that they really do get good mileage and are big enough for almost everything). Now our street has nine Prius drivers. Did I cause this — maybe not all of them.

But my personal efforts matter because:

• By making changes, I learn what works and what doesn’t
• My purchases and support of products that enable green choices help make their companies viable
• People see and hear about what I do and a few might start doing things on their own
• I have learned enough to participate in the debates with actual knowledge and facts
• As more people come to see various realities, and understand, they influence their leaders

In short, my personal efforts affect others’. And their actions also affect others. It doesn’t take long to get to billions of people, actually.

I am actively participating in a movement that was underway long before I was part of it. Buying an electricity monitor is just one way that my actions affect others.

Oh, and I pay about $250/month less for energy than I would otherwise.

I expected nothing less of Google PowerMeter — week by week, it continues to improve. Now the graph displays my usage compared to expected use, and includes a visual and numeric accounting of my baseline, “Always On” usage compared to total usage. Here’s what my graph for today looks like:

Three Great Things

The expected usage gives you a nice target, and the comparison to others provides a helpful benchmark.

But the new “Always On” measure provides two very helpful bits of information.

First, the darker bar helps isolate the spikes above. For example, the most obvious repeating spike above is the refrigerator — it cycles on about once per hour and runs for perhaps 25 minutes each time, running at a bit over 200W — it’s easy to see that pattern. (more…)

Google PowerMeter showed me I was wrong about something. Well, sort of.

Perhaps you have noticed: I am a little obsessive with my measurement of energy usage. Despite being an energy saving zealot, we still use our electric clothes dryer — perhaps as a rationalization, I had claimed that all those other people saying that we should use our dryer less had it all wrong. I said that this caused people to lose focus of the smaller items, especially the ones contributing to your “baseline” usage.

As I have pointed out, but said more nicely in a great article on PlotWatt’s blog, 100 watts, on all the time, costs about $100 per year for most people (more for us in the Northeast). Over the course of measuring electricity usage with several power monitors, I have reduced our baseline usage from about 700W to around 200W, which saves me a good deal more than $500/year in electricity bills. Finding the little energy vampires like my old Dell laptop which wouldn’t sleep on its own, to the old cable box (replaced with TiVo), to the 2 buttons on my “off” receiver, to the computer server in our hall closet — all eliminated, and all reduced our baseline. Success.

So was the dryer really that important? I have to say, it seems so now. Here is a series of screen captures from (actual) data from my TED 5000 now hooked up to Google PowerMeter, which I can see from my iGoogle home page.

What do you see? (more…)

Google announced today that the TED 5000 (The Energy Detective) will link directly with Google PowerMeter — the TED 5000 scores big!

Update: Tuesday Sept 6^th — TED Firmware page reports that Google PowerMeter software will be available this Friday afternoon.

Who cares? Well, I know that real-time energy monitoring devices make a huge difference in behavior, or at least they can.

And I know utilities are going to get to that smart grid “real soon now” (just as soon as they stop hand-typing my electricity bill). Look, there’s a reason that The Electric Company is the worst property in the game Monopoly®.

But seriously, allowing real people to get themselves hooked in to a larger network of data that Google can collect, analyze and do their usual greatness with should offer a few early-adopter types the chance to show the true power of data aggregation again, this time with electrical power.

The Google Power Meter blog says the functionality is enabled in the latest TED 5000 firmware, so I downloaded it … but I cannot see anything different. I already had the 1.0.214 gateway firmware installed, and now have Footprints 1.0.103 installed (the latest as of 11pm EDT, 10/5/09). But I see nothing. The TED 5000 site says little (although there’s now a screenshot of PowerMeter). The Google Power Meter site says little, and the newsgroup has nothing new posted.

Am I just being impatient? Yes! I want my TED 5000 household electrical use data to be on the web so everyone knows that I don’t line dry my clothes (and they know when, too.) Well, also I want to be an über-energy-geek.

More to come. Soon, I hope!

As I have often mentioned in these pages, we had an energy audit last Spring. The audit was a seminal moment in my understanding of our household energy usage.

Mission Accomplished! (Or Is It?)

I talk to a lot of people about their energy conservation measures. Naturally, not wanting to look uncaring, people talk about how they have changed and are going green. Perhaps a light bulb or two changed to CFL. Perhaps they a jacket on their water heater. Some weatherstripping on their door? A programmable thermostat?

These changes sound fine, and they may actually make a difference. But there are two ways that just making changes alone doesn’t really change things.

Perhaps your two CFL bulbs reduce your electrical use a little, but isn’t it important to know how much? (For example, the oft-repeated water heater jacket is of almost no value if you have a relatively newer one). So it’s possible that your changes haven’t improved anything. And the second way changes alone are bad: you may feel like you have “gone green” … mission accomplished.

So to my great chagrin, I realized recently that I had very little clue what my heating usage was, or for that matter what it should be. I had made lots of great changes. Mission accomplished? Not so fast. (more…)

Oh yes, I have it.

This afternoon, we started cooking dinner and I made the mistake of glancing at my TED 5000 display. It was reading 1,019 watts at the moment. What the…?

This wasn’t right. We had three lights on in the kitchen at about 35W each. The TV was on in the living room — nope, that’s only 180W. To confirm, I asked Carter to turn the TV off, checked the display, then on again. Yep, about 180W. The fridge was on — I had just gone to the market and opened the freezer and fridge sides so it was re-cooling. That’s around 200 Watts.

I checked downstairs to see if the dryer was on, or something else. Nope. Was the Smart Strip working (the kids had been playing on the Wii earlier, but I have it set up to turn everything off when the TV goes off.) Nope.

Fish tank? I had been suspicious of it for a while and had my Kill-A-Watt plugged in to the socket. But it’s 100W heater, when on, used 100W as advertised. The filter was just a few watts. The fish are safe … for now.

I checked upstairs. Carter’s computer hadn’t gone to sleep … but that couldn’t explain it. I put his computer to sleep. Hardly any change. Theresa’s computer was off, mine was asleep. What the…?

So I looked at the TED graphing, and here’s what I saw: (more…)

As I have become aware of my energy use, I have grown more interested in understanding the details. I have used four methods to measure my electrical use:

1. (actually) reading the electrical bill,
2. using a Kill-A-Watt meter to measure usage of things we plug in,
3. installing a PowerCost Monitor to display total house usage right in our kitchen, and
4. installing a TED 5000 monitor that measures and records our usage in great detail

Each of these methods is effective, and each has resulted in incremental changes. For us, the incremental changes have added up: we now use less than half of the electricity we used to. Everyone can do at least the first of these — I hope I’ll show you why it makes sense to go a step further. (more…)

The Green Inc. blog had a good post today about building codes that require energy efficiency, along with the idea that there should be a national standard. In my former life, I worked in the building trades, has a builder’s license, and know that the idea of being an effective builder is to either a) build pretty close to the code, and no more, or 2) bribe your local inspector as needed. In either case, the building code set a standard, and most of the violations I saw were minimal — building codes work. (more…)

I just spent an hour (while on my vacation) entering home energy data for my house into Microsoft Hohm Energy Usage site. I provided a great deal of home data — items like square footage of windows, BTU/hr for my furnace, R-values of insulation in my house. After finishing this part, I was told that my energy providers are not yet Hohm partners, so unless I enter my energy use data manually, I get pretty much nothing other than a breakdown of energy use in a pie chart (which, since I have done this myself, I know is inaccurate).

In the end, they provide a list of recommendations — many were ones I had already done (and said so in the survey) such as using a programmable thermostat. Come on — that’s lame.

It is true that Hohm is not the same thing (in any way) as Google Power Meter. (more…)

I while back, I reviewed the Shower Professor shower timer. I had tried an egg timer variety, but you really have to look … and it’s steamy in a shower. Cheap, but … cheap. I looked around at several other options, but they are kind of pricey. Heck, somebody has a serious issue if they need to buy one for $125 that has a password and locks the water off after a preset time period. Either that or they have a teen-aged girl (I’ll have one of them in a few years, and am bracing myself).

But if you are in the group of people who just want to do your part to save a little water, and save a fair amount of money, I am still happy with the simple $5.99 digital timer that I use, with the hokey name the Shower Professor. It beeps at the right pitch and volume: you can hear it, and it stops after five beeps so you don’t have to do anything to avoid waking up the household. And it has several reasonable preset times — it has gotten to be a habit just to press a single button when I get in — unless I haven’t had my coffee yet, I’m in and out in about 4 minutes. My wife shaves her legs, so her showers are longer — there’s a good preset for that. The kids use it, too. Because it’s easy. (more…)

A new device will soon be available, and if I could place a pre-order, I would — it’s the TED 5000, and it looks like a big step forward.

[Update, August -- TED 5000 Release Date: The TED is now available for order by phone from the manufacturer; I have one now, and wrote installation notes; see links for details]

I currently have a BlueLine PowerCost Monitor — it is very good device, and I still recommend it. Using this device, we have even further reduced our energy cost for electricity by a significant amount.

But there’s a new game in town: the TED 5000, set to be released this month (June 2009). It solves a whole bunch of problems that the PowerCost Monitor and its existing version do not.

Indeed, the TED 5000 may be a very reasonable alternative to the smart meter your electric utility is going to install, then configure. The difference is that your utility may take years until they get all that done and provide the kind of information you could have right now.

And the savings are big indeed — from our current real-time power meter, we have saved a great deal of money on our electrical bill, and save every month.

But while going from a dumb electric bill to the PowerCost Monitor is a big step, it certainly has its limitations. (more…)

There are a lot of tips out there about how to use less energy with your refrigerator — the ones I have seen aren’t wrong, but I think they can be misleading. I would never argue that improving efficiency is a bad thing, but it’s important to keep the big picture in mind.

According to the US Energy Information Agency (EIA), refrigeration accounts for only 5% of household energy use.

So, this being the real picture, my blog is all about how the little changes we make can indeed add up. And I encourage people to do whatever changes they can — there are plenty out there, to be sure!

So with the big picture in mind, here are some of the factors to think about relating to refrigeration.

The Big Picture (of Refrigeration)

You may have read that adding jugs of water to take up space and act as a “buffer” is a good idea, and it is (unless you do what I saw a friend do).

There are several reasons why adding water bottles to the fridge (or extra ice to the freezer) make it more efficient. First, solids and liquids are better at storing heat energy than air because they are more dense, so they act as a “buffer”. Additional items in the fridge also mean that when the door opens, the vortex of warm outside air rushing in is disrupted — the things that are already cold stay put, especially if the jugs are in the front.

But there are some questions to consider before loading up on water jugs. First, the fridge has to work to get those jugs of water from whatever temperature they are at to the cooler temperature inside. I saw a friend who filled a jug of water to put in the fridge, but happened to have the water faucet on the “middle” setting — he ended up putting warm water in. Whoops. And how full is the right fullness — if you take the water out every time you shop, then put it in a few days later, it’s hard to say that there’s a net benefit. (more…)

We recently had an energy audit for our house and learned a lot, including:

• The most of the corners of the house were never insulated the first time
• Our bulkhead door leaks like a sieve (maybe that’s why I can see light through it :-)
• The attic door and whole house fan let in a lot of air
• The chimney damper is pretty useless in terms of insulating
• Air pours into our basement through the sill and old windows
• Most of our windows still need to have caulking around the edges — air is getting in
• All the leaks result in a complete air exchange about once every 70 minutes in winter

How the Audit Worked

There were two parts: a “blower door test” and an infrared camera inspection (the actual reports are linked below). (more…)
