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?

Civility

Category: Editorial – Tom Harrison – 9:20 pm

Earlier this week, Mark Mondik wrote a post on the TerraPass Footprint blog regarding population. The post itself is remarkable for its measured and rational observations about the topic of over-population, one that has, through the course of modern history, raised the specter of many horrible things. Do you remember Charleton Heston in Soylent Green?

But what I found even more remarkable is that, over these last four days, the comments, now 37 of them, are all civil. Not all are in agreement, and there is a discourse raising several different points. But the comments are all respectful, honest, thoughtful and well-meaning. (And while TerraPass is up-front about their lack of tolerance for abusive or off-topic comments, none have been deleted — I subscribe by email, so you know when that happens).

I was cheered by this remarkable achievement in Internet history, and have hopes that it may herald a new era of civility.

Philips Halogena Review: Dimmable, Warm, Less Energy

Category: Green Reviews,Household,Save Electricity – Tom Harrison – 12:12 pm

philips-halogena-r20Philips “Halogena” bulbs are not CFLs — they are incandescent bulbs that use less electricity than standard bulbs, and they work exactly like the bulbs they replace. They claim to last about 20% longer, also. Halogena bulbs cost more, about $3 more, per bulb in my case.

I could see no difference in performance compared to incandescent: they start instantly, have nice bright light at full power, nice warm light as they dim, and they dim continuously with no buzzing, the bulb looks the same and fits.

I would have preferred to use CFL bulbs: compared to standard incandescent Halogena bulbs use about 1/3 less electricity; CFLs use 4 to five times less. CFLs also last a great deal longer, even than Halogena’s modest 500 hour improvement. So Halogena are an incremental improvement.

But as per the mission of this blog: saving energy and conservation is a matter of a lot of small steps that add up to big, big savings. (more…)

Energy Audit: What We Learned

Category: Energy Audit,Household,Save Fuel,Take Actions,Tips – Tom Harrison – 12:27 pm

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…)

Simplicity: Cast Iron Skillet Beats All

Category: Conservation – Tom Harrison – 5:08 pm

skilletTheresa and I have been married for a while now, coming on 15 years. During that time, we have had a lot of pots and pans. I’ll talk about our frying pans.

We started out with a cast iron skillet that I had owned since the year after I graduated from college. My Mom taught me about how to season a cast iron pan so food wouldn’t stick.

Then as we got more money (still “dink”s — dual income, no kids) we went upscale, buying Calphalon. These are anodized aluminum — solid and thick, with steel handles solidly bound on. These pans were the ones used by chefs in real kitchens (more…)

Home Energy Projects for 2009: Request for Comments

Category: Conservation,Energy Audit,Household,Sustainability,Take Actions – Tom Harrison – 6:52 pm

I have several household energy reduction projects in mind and am hoping to get some advice about which one I should take on first. I am considering:

  • Tankless (on-demand) Hot Water Heater
  • Foam Spray Insulation combined with Energy Audit
  • Geothermal Heat Pump
  • Solar (PV or Water Heat Assisted)

I have a lot of questions about which ones make sense, how to tell which one is best, how much they’ll cost, and how to measure all of it. (more…)

Windows XP Standby and Hibernate Problem (Update 5/2009)

Category: Conservation,Little Things,Save Electricity,Tips – Tom Harrison – 11:24 am

No Standby

No Standby

In June I wrote about how I had solved my problems with windows XP not going into stand-by or hibernating. That post is a good overview of the problem, with suggestions on how to diagnose and narrow down the problem. There is also a good thread of comments there.

Judging from the traffic I have been getting on that post, it seems that many others are having the same standby issues as I. And there are some other standby solutions I have found since then. I’ll try to keep updating this post, and I encourage anyone with other findings or questions to comment.

Update History

  • (edited 9/7/08, added test methodology)
  • (edited 9/9/08, added suspected Google Reader issue and 5 minute test period)
  • (edited 9/14/08, results of testing free utility, Smart Shutdown — it works! It used to work :-( )
  • (edited 10/21/08, some XP SP3 Hibernate problems and possible solutions)
  • (edited 11/17/08, added firmer “shut down everything first” to test procedure)
  • (edited 11/18/08, added “verify manual standby works” to test procedure)
  • (edited 12/13/08, clarified case where iTunes causes problems
  • (comment #17 on this post, 1/1/09, Java QuickStart
  • (comment from other post, 1/29/09: Symantec AV suspected
  • (comment from other post, Installation of SP3 kills hibernate option; see below)
  • (comment from other post 2/26/09: Adobe Type Manager causes Keyboard error entering standby, confirmed by Microsoft)
  • (additional bolding of some other solutions in comments, 5/22/09): Spamblock Plus, VOIP connection, MSN, others suspected.

eRedux: making “act locally” a lot easier

Category: Cool Sites,Take Actions,Technology – Tom Harrison – 9:01 am

eRedux is a new site providing resources that are aimed specifically at getting things done locally. Maps and charts of carbon footprint by state, regional and local level are available. US Government and other sources of local data are grouped together by zip code with links to various resources right there.

But what I think is especially cool is that there’s a town, county, and state blog that members post entries in, comment on, and communicate with each other.

I just made a post soliciting people in Newton, where I live, to help me get my new green site (that still has no name yet) off the ground. I really like this idea and hope it can grew and be successful.

How much energy do you use in your house?

Category: Conservation,Household,Save Electricity,Save Fuel,Save Water,Technology – Tom Harrison – 2:00 pm

My recent windfall from the water company reminded me that I could not possibly have known how much water I was using. I am not so tied in to our heating bill. I am very aware of my electricity bill. I am aware of my vehicle usage. They are all important—why the difference?

When it’s in your face, it’s harder to ignore

I have some proposed solutions that should help get our consumption in our faces. (more…)

Spending More Than You Earn

Category: Big Things,Cool Sites,Sustainability – Tom Harrison – 6:36 pm

Are you like many Americans who spend more than they earn? Well, if you’re talking money, that ain’t the half of it.

Americans “spend” more resources than we make by about 5 times (more…)

How to Rationalize a Widescreen TV

Category: Household,Save Electricity,Sustainability,Technology – Tom Harrison – 11:31 pm

Conservation is not the same as deprivation. I saw a show on TV this summer called “30 Days”, which was created by Morgan Spurlock, the guy in “Supersize Me”. In one episode, two egregious consumers of the earth’s limited resources are put into an experimental eco-commune for 30 days. We watch as these SUV-drivin’, meat-eatin’, blowdryer-usin’ two people are thrust into a place with people living a “zero footprint” life. They eat only what they grow, they recycle their waste, they retrieve vegetable oil from restaurants to power their car. So we see people whose lifestyle is perhaps admirable, but utterly different from most Americans. It was good TV, and presented a lot of facts about how badly we are abusing the earth. But it did not present options that our consumption-addicted country can really act on.

Indeed, radical viewpoints can be counter-productive. (more…)
