Five Percent: Conserve a Little Energy

If you cannot change the world by yourself, start by making a small change … just 5% less is easy, and here’s how.

Air Conditioning: 100 Percent Efficient (Minus Travel)

Category: Climate Change,Observations – Tom Harrison – 1:25 am

It was 97°F in Boston this week, and we didn’t turn on the air conditioner. Or fans.

That’s because we’re not home. We have vacated the heat of the city. Where we are, it’s a little chilly at night. We have the ultimate luxury. It’s not a central air system. It’s not a super-insulated house. It’s a very small, spartan cottage, on the water of Penobscot Bay in down-east Maine, which I share with my sisters.

My mom, who is in her 80′s lives here in Deer Isle, Maine, year-round, and visited tonight. She was born in Baltimore, and as we discussed the heat wave along the East Cost (consistent with the predictions of climate change), we asked how people managed to tolerate the heat in Maryland in the 1930′s. She said that her rich friends all got out of town and headed for the ocean. She said she grew to hate places like Cape Cod, Nantucket, and Maine where her friends went — she was stuck in Baltimore. She spent her summer afternoons reading quietly, under a shade tree. Perhaps it’s not ironic that she moved here with my dad in the mid-1970′s.

In the 1930′s, only the wealthy were able to travel to cooler climates. My grandfather on my Dad’s side was an English professor at universities in Ohio and Indiana, and it was my grandmother’s family who had found a small island in Maine to go to when the weather became unbearable in the mid-west. The stories of their epic travels, by carriage, train, and eventually by a ferry from Rockport (before they built a bridge) were astonishing. But then again, they came when school was out, for the whole summer.

Even as a child in the 1960′s, the trip from Connecticut by car — down to 10 hours or so once the Interstate system was finished, seemed epic. But we stayed for a month.

My grandfather and mother stayed for the whole summer. My parents came for August. Until recently, my family came for a week, or perhaps two.

I wonder if my children will have the chance to come at all?

The only noise our air conditioning makes is the waves of the frigid Maine ocean water breaking on the beach.

Before we left our Boston home, things were beginning to swelter. We have girded our house in many (if not all) of the ways possible from the elements of winter and summer. Yet my office, designed as a sun room, is not surprisingly, quite hot on a bright day, despite air sealing, insulation on all sides, double insulated glass, awnings, fans, and the like. It’s fine, but it’s not “chilly”.

Having been here a week, and with several more to come (thanks … I guess … to a solid DSL line and WiFi so I can work) I can live for a while in the comfort of the oceanfront. The mountains are good, too.

But of course the majority of folks in our every larger world haven’t such a great and incredible luxury. We had a visit to Europe in July last year, and were pleased to see that few had turned to air-conditioning, and instead lived in houses and apartments sensibly designed for the conditions — stone, shaded, small, and designed for cross breezes. And yes, fans. Rich and poor alike have eschewed air conditioners … and Paris, at least, is not a cool city.

But still, most people don’t live in Paris. Most of us in the US live in places that are downright inhospitable during one part or other of the year.

Why? Indeed, we’re flocking to places like Phoenix. Does this make sense?

Why have we created huge population centers in places that are intolerable for much of the year? Why have they grown and flourished?

Because of heating and air conditioning. And mostly the latter.

Heating is easy: build a fire, whether by wood, coal, gas or oil, we can keep warm just by burning stuff.

The physics of cooling is far more sophisticated. Actually, cooling is just a form of heating, taking the heat out of one part and moving to another (with a good deal of energy required to perform the heat transfer miracle). Other than ice, stored from rivers frozen in winter, there wasn’t cold stuff above ground until air conditioning started proliferating in the 1950′s. And below ground was a little cooler, but pretty moist.

But the cool basement, or an ice house — these are things of the past.

Now, in the cities, towns, houses, and pretty much everywhere, even here in Maine, people are able to easily buy, install and turn on air conditioners, or central air systems to keep their whole house dry and comfortable even when it’s 100°F outside. Just plug ‘em in. Our cars, offices, restaurants, movie houses, and even back-yard patios are air-conditioned.

We sit on our patio in the cool evenings in Boston, where temperatures sometimes fall into the 70′s and listen to the sounds of the central air compressors running, even though there’s cool air to be had just on the other side of that window, if only it would open.

As a boy in Connecticut in the 1960′s, I remember the day when my Dad brought home a window air conditioner. On the hottest days, I would be allowed to sleep in my parents’ room, where it was installed. It was heaven — almost as good as Deer Isle (except noisy as hell). On days other than the hottest days, it didn’t run — it was far too expensive.

This shift to full-time conditioned space is a stunning development, happening wholesale, in the last 50 years or less. Even many of the least well-off folks in the US probably have some air conditioner. Just as they have heat, computer, TV and a car — things not in existence 100 year ago are now a simple necessity.

It occurs to me that air conditioning (and heating, which happened earlier, since it was easier) has allowed us to live in places not fit for the kind of busy lives we need to live to be productive American consumers.

And what has enabled this? Mostly the ready, accessibility of energy, with a few good dashes of enabling technology, and our increasing intolerance or ability to handle discomfort.

It may be true that we can generate sufficient renewable energy to maintain this rather bizarre and energy intensive lifestyle — one devoid of vacations to the sea, or mountains — one requiring work for all but a week or two of the year. We certainly have plenty of solar and wind, in the long run to power our heating and cooling needs, and we have the technology to make our dwellings and vehicles more efficient and climate controlled. I think it’s good that this is true.

But as I listen to the high tide hit the beach outside, and realize that I am a little chilly, I wonder — isn’t a trip to another place, even if costly in terms of time, travel, alternate spaces, and so on — isn’t it something we need to think about building into our complex modern lives?

Is it easy to say for me? Yes, of course. My sisters and I inherited a beachfront cottage in Maine — a behest not coming to the vast majority of the country or world.

But it makes me think: is there something we have forgotten in our lives? Is home something we cannot leave but for a week or two? Even if we had unlimited energy and super-efficient houses, there’s something else that getting away does for your view of the world.

Has the cheap energy of oil, coal, and gas, and the technology that has built around it changed our way of life to a point where whatever comes next is something that is different, but maybe not better? Could a look at our past give us an idea of what might be better?

Oil, Gas, Coal, Nuclear, Hydro, Geo, Wind, Solar: Which is Worse?

Category: Big Things – Tom Harrison – 8:12 pm

Please rank the relative cost or trade-off of

  • oil
  • natural gas
  • coal
  • hydro
  • geothermal
  • wind
  • solar

When you rank, consider things like

  • value
  • cost
  • climate
  • benefit
  • alternatives
  • risk
  • economics
  • jobs

What were your criteria? Were they different than they were a few months ago?

Are corporations inherently evil? How about people?

Is mountaintop removal a good way to get coal? Would you pay a little more to get coal other ways?

Have you hear about Gasland? Did you know that natural gas releases about half the CO2 that coal does when burnt. Did you know natural gas prices are falling compared to others?

Does any of this have to do with water (by which I am not just talking about the tap water that is flammable, but really more about the tap water that doesn’t come out of the tap).

Do you remember Three Mile Island and Chernobyl? Do you think we’ll figure out a way to get rid of spent fuel?

Isn’t it bad to flood massive valleys to create hydro power?

Are we concerned about bird deaths from wind? Or what about the idea that putting up lots of wind towers will interfere with wind (Don’t laugh). How about the visual destruction of the landscape?

Isn’t solar a little silly, since it only works on clear days?

Don’t electric cars use batteries that create massive environmental destruction?

How concerned are you about the impacts of climate change? Do you think some of the weird weather and stuff is just normal weirdness? Do you think we’ll find ways to sequester CO2? Will it do any good?

Do you believe in Peak Oil? (or Gas? Coal?). How does that play into things.

Can we resolve any issues that might arise without significant conflict?

What would happen to you tomorrow if the power went out for the day. (In case anyone reads this later, it’s June 26th, 2010)?
How about a few days?

Did you ever watch Mad Max?

These are just a few questions. I think we probably need to be thinking about them. Because there’s really no single good answer.

I don’t have any answers at the moment, but these are some good questions, if you ask me.

Why the Jevons Paradox Does Not Apply Today

Category: Climate Change,Conservation,Economics – Tom Harrison – 11:02 am

In a couple cases recently, I have heard people talking about how the Jevons Paradox will undermine efforts to use energy more efficiently — and it certainly seems like it would fit, but it doesn’t apply to our current energy problems for several reasons: conservation, and improved efficiency are still our best options.

Or, so started a post that I began writing a couple weeks ago. Then, in some sort of karmic mind-meld, Peter Troast at EnergyCircle.com wrote a post about Jevons, with almost the same conclusion as I was going to draw. Yeah, right, I hear you say.

So anyhoo, I think this topic is important to the larger discussion of energy, especially renewable energy, so here’s a link to Peter’s post on energy efficiency, which already has a nice thread of comments and observations — take a look, it’s a good read — and, add your thoughts!

Do We Need An Oil Spill for Climate Change Action?

Category: Climate Change,Policy – Tom Harrison – 6:18 pm

(I wrote this on May 28th, but never published. I am publishing now because I think things might have changed enough).

I have an opinion about just about everything, including opinions. Daniel Weiss did a nice post on the Climate Progress blog showing how dramatically public opinion has shifted in the month or so since the oil spill started.

In short, people don’t think offshore drilling is such a good idea any more, and they’re willing to trade off economic development for environmental protection.

In my opinion, this shows how little value there is in the opinions of people. I am not trying to be negative, or get attention by being contrarian, smug, or elitist.

Instead, I think we’re at some rather great risk of self-destruction if we keep making policy opportunistically, and avoiding discourse and action until the time is right. (more…)

“Spill Baby, Spill” – Oil Leak “May Be Five Times Initial Estimate”

Category: Climate Change,Companies,Energy Independence,Political – Tom Harrison – 8:26 am

Credit: New York Times

I think I should claim a scoop on this story, as when I wrote my post the other day, I had beat the New York Times and most other media to identifying the BP Oil Spill as a rather major disaster. I am sad to say “I told you so”.

The news media seem to be coming around to my way of thinking. The New York Times is now reporting as the lead story that, um, those 42,000 gallons of oil per day leaking into the sea may be more like, um 210,000 gallons (this is all converted to “barrels” now — an oil barrel holds 42 US gallons, so the initial estimate was 1,000 barrels/day is now 5,000).

Holy hole, Batman!

And it appears that BP’s public relations operation has also gotten bigger.

Fortunately, the problem isn’t that bad. No, really. (more…)

Oil Spill: A Great News Day for British Petroleum

Category: Companies,News,Technology – Tom Harrison – 7:41 pm

oil rig explosion

Not As Important as...

I was surprised to hear (for the first time today) that there was an oil drilling platform in the Gulf of Mexico that, um, exploded last week (a couple days before Earth Day), and is currently pumping 42,000 barrels of oil a day into the water, and attempts to shut down the leak (1 mile down) have failed repeatedly since the leak was discovered on Saturday — I happened to be in my car and heard a report on NPR.

After dinner, I went to the New York Times to read more.

But I didn’t find anything without a search. Granted, lots of news today:

  • Goldman Sachs CEO questioned on possible fraud
  • Republicans blocking attempt to reform our financial regulations
  • Stock market down 2% because Greek credit rating cut to “junk”
  • Strict abortion measures enacted in Oklahoma
  • Impacts from Arizona’s immigration laws

So I started trolling around the sections. World: nada. Business: nope, all front page stuff, plus Ford makes a big profit. Technology: Apple iPad related story. Science? Nope. Green? Nope. (Really!) Health? Nope. US: fifth story, something about Robots (turns out to be about the oil disaster).

Good thing for British Petroleum, apparently a lot of other big news pushed their little disaster to the back of the book. (more…)

Energy Prices on the Rise (Again), Oil Over $80/barrel (Again)

Category: Economics,Policy – Tom Harrison – 8:00 am

Volatile Natural Gas PricesIn the last month, oil prices have been over $80 a barrel — prices were over $86 twice, fell, and are now back on their way up.

Gasoline prices are around $2.80/gallon, up from around $2.00/gallon a year ago and rising a little each week over the last month.

Heating oil cost has risen over the year from $1.40/gallon to around $2.20/gallon.

Natural gas is also up year over year, rising from around $3.50/MMBTU to around $4.00, and volatile, closing over $7 for a few days in the winter.

However, domestic US Coal prices are about even, down a little, this year (from $2.21/MMBTU to $2.14) — I guess the energy we produce at home can be less expensive. Too bad burning coal releases about 2x the CO2 of natural gas (and a great deal more than wind and solar).

How We Respond To Energy Price Changes

But it appears that only energy prices drive our behaviors. We tend to over-react in some ways (markets, producers, consumers), yet have remarkably short memories, and seemingly weak abilities to identify coming changes.

I do understand that many people are negatively affected (more…)

Cap And Trade: My Comment Turned into a Post

Category: Climate Change,Political – Tom Harrison – 8:19 pm

As anyone reading can plainly see, I am clearly more involved in working for and writing for my new company, Energy Circle which is all about home energy efficiency than about writing here on my personal blog.

As it happens, I am continuing to respond to comments and engage in dialog with people who are reading. And given that I just spent an hour writing a response to a comment on one of my posts about cap and trade, and also because there was a related and article on climate change, cap-and-trade, and science by Paul Krugman that you should take the time to read, I figure I should create a short post for all 12 people who still follow the blog.

So there you have it. Read the article, and read and comment on my comment response!

Cape Wind Attacked By Its Own Proponents

Category: Climate Change,Conservation,Policy,Technology – Tom Harrison – 10:32 pm

I am beginning to think Jane Fonda is going to reincarnate (sorry, is she still with us?) and create a sequel to The China Syndrome called The Cape Windrome or something. Today the Advisory Council on Historic Preservation recommended that Cape Wind not be approved. Because what, the waves of yesteryear are going to be different? Come on, let’s get a little real, please?

The single most infuriating example of how the United States is sometimes able to undermine even the simplest, most obvious options is being played out in the great saga of Cape Wind. A small array of wind turbines is planned for Cape Cod Bay, generating a substantial amount of power, efficiently, locally and cleanly. But it represents change, and change is bad. Right? (more…)

Oil Prices over $80/bbl for last week, doubled since last year

Category: Climate Change,Energy Independence,Policy – Tom Harrison – 9:51 am

The stock market isn’t the only thing to have recovered since this time last year — in fact where stocks have increased by 48%, good old oil has doubled. Perhaps you have noticed — I paid $2.85/gallon for gas yesterday.

There are no suggestions that oil prices are going to tumble any time soon; on the contrary, gas is expected to pass $3/gallon this Spring.

Personally, my issue is climate change, but if you’re into the economy, or security, or other things, what part of this picture is unclear? (more…)

How Not To Make an Efficient House in 13 Years

Category: Energy Audit,Household,Save Fuel,Take Actions – Tom Harrison – 10:46 pm

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…)

Results of my Energy Audit: Before and After Pictures

Category: Conservation,Energy Audit,Household,Save Fuel,Take Actions – Tom Harrison – 10:31 pm

In the Spring of 2009 I hired energy auditor Flemming Lund to do an energy audit on our house — I posted pictures and the full report — it was pretty amazing. I had some work done this summer (air sealing and insulation), and did some more on my own this fall — mostly caulking and stuff. Then I asked Flemming to come back and re-do the test. I told him he would have endless fame, fortune and that I would continue to refer customers to him, so he graciously waived the re-audit fee (thanks Flemming!)

And here are the results. Well, actually, the results are on Energy Circle — they have real editors and a wider audience than little ol’ Five Percent, and it was Energy Circle that helped me find Flemming and learn about a lot of this stuff from the start.

I hope you’ll take a minute to pop over and read my story. Our savings from the whole process, from an energy audit, air sealing, insulation, and good old caulk are pretty impressive, if I do say so myself. (more…)

Google PowerMeter: New (Useful) Features, New Device

Category: Companies,Conservation,Save Electricity,Save Fuel,Technology – Tom Harrison – 3:09 pm

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:

ted-5000-and-google-powermeter-oct-31

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…)

How to Tame Your DVR’s Appetite for Energy: Starve It

Category: Household,Save Electricity,Tips – Tom Harrison – 7:56 pm

My cousin Alison wrote me an email this evening asking how she could stop her always-on DVR (the “not-a-TiVo®” things cable companies will rent) from gobbling electricity.

Here’s her email,

I am trying to do my next round of tightening up and have read all the stuff about turning off your “always on” appliances, but after much googling couldn’t find the answer to my real question: if I turn off my cable box, will my dvr stop recording?

So then I remembered—aha, my cousin Tom’s website.

And spent a little more time surfing around there, which was incredibly informative and pleasant BUT I still couldn’t find the answer.

So then I thought I’d take the lazy way out and just ask you.

Will it?

Your very very pale green cousin

alison

To which I promptly and thoughtfully replied

Yes, it will stop recording.

However, consider the following tip: if you have nothing to record between, say midnight to 4pm, you can do this:

1) Plug everything (TV, Cable Box, DVD Player, whatever) into a power strip
2) Plug the power strip into a light timer
3) Set the light timer to turn off at midnight and on at 4pm
4) plug the light timer into the wall

Then, not only will you miss little or nothing, you will get rid of the power of the cable box and the standby power of the TV and whatever else, and have the whole system off for two-thirds of the day.

Light timers and power strips can be bought at drug stores, grocery stores, hardware stores or online.

Your friendly neighborhood energy conservation cousin,

Tom

I Believed I Was Conserving, Until I Looked at the Facts

Category: Conservation,Energy Audit,Household,Save Fuel – Tom Harrison – 4:12 pm

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…)
