The following is a short outline of the event. For the complete gathering summary, see our pdf files:

You can also view Jeff’s slideshow as a pdf file (2.1 MB so takes a while to download): Slideshow: Renewable Energy Solutions. Some of his slides are blurry or impossible to read (slides 6, 7, 10, 43, & 65); if you want a copy of these slides at higher resolution (4 MB file) please contact Catherine: cat(at)essentialstuff.org.

Energy: Sources & Consumption

Sunday, June 20th, 2010

by Catherine Haug

This coming Wednesday (June 23, 2010) we will be hosting a presentation by Jeff Arcel on Alternative Energy. It’s important when considering this topic to have a good understanding of where our electricity and fuels come from, how they are used in our society, and the true cost of energy use.

A few months ago I wrote a post on Alternative Energy and EROI (EROI is Energy Returned on Energy Investment) which discusses a pertinent topic. Now lets look at where our energy comes from and how it is used across our society. (more…)

The Age of Petrochemicals & Going Green

Offshore Oil Platform

Now that we are all grieving at the sight of oil-soaked pelicans in the Gulf, we call for an end to our dependence on petroleum. But have you ever thought about what all we’d have to give up? It’s not just fuel for our cars and home heating systems, or that airplane ride to our favorite vacation spot. We’d basically have to give up all that we’ve come to take for granted.

That’s what an article in June 13, 2010 Daily Interlake by Seth Borenstein, an AP Science Writer, titled Boycott Big Oil? Prepare to give up your lifestyle (1) is all about. It includes a litany of all the common, everyday things that contain substances made from crude, or depend upon crude for their maintenance or production.

It’s about what this means for our society; how far we have strayed from The Essential. “Petrochemicals are the glue of our modern lives and even in glue, too.” (1)

Here’s a partial list, from the article: (more…)

Home Energy Conservation: Windows & Doors

Wednesday, May 12th, 2010

by Catherine Haug

Unless congress extends the deadline, 2010 is the last tax year that you can take a federal income tax credit for replacing doors and windows with new energy-efficient ones, or adding storms to existing windows. However, before taking that big (and potentially expensive) step:

  • Consider an energy audit to determine just how bad your windows and doors are.
  • Then compare the overall cost of replacement, with that of repair and maintenance.

If you have an older home (built prior to 1960), repairing and retrofitting existing doors and windows with storms might be a better tax-deductible option than tearing them out and replacing with new aluminum, vinyl or clad windows. Not just for immediate cost reduction, but for a better maintenance cost reduction going forward. (more…)

Gathering Summary: Oil + Water Film, April 28, 2010

Monday, May 3rd, 2010

This was a different kind of event for ESP, in that we showed a film (not one we’d made ourselves): Oil + Water, a documentary of two young men and their road trip from Alaska to the southern tip of South America.

For more information about the film:

This summary includes a synopsis of the film, and the discussion that followed. For a printable copy of this summary, see Gathering Summary: Oil + Water (the Film), April 28, 2010. (more…)

Rail Transit in the Flathead?

Thursday, April 15th, 2010

by Catherine Haug

Two years ago, gas was over $4/gallon; it won’t be many years before it reaches $10 or even $20/gallon, as demand rises against declining supplies. And it isn’t just the gasoline that would be costly; everything that depends on petroleum or the power it generates will be more expensive: the cost of generating power to mine and refine the steel, aluminum and other metals; to create the plastic and vinyl; and to operate the robots that assemble the cars. Even to build those robots.

So a car that sells for $25,000 today, would cost at least $75,000 when gas is $10/gallon; $200,000 when gas is $20/gallon. Who could afford that, even if the cars are twice as fuel efficient as they are today? Especially if you had to pay 3-times as much for your groceries and utilities that are also dependent upon the cost of gas. [Cost projections are my own best guess].

And then there’s the cost of asphalt or concrete for all the new and rebuilt roads. Asphalt is made from petroleum, so its cost would also rise, as well as the cost to manufacture and lay the concrete. Of course, with rail, there would be the cost to build/rebuild the tracks that must be considered, so it has to be planned smartly.

So why not imagine and plan now, to be ready with an alternative when we can no longer afford cars and highways.

The AARP Bulletin for April 2010 features an article on “Streetcar Revival” for urban communities. The online version of the article does not feature the cityscape photo that accompanies the paper version, a scene familiar to my eyes because I used to live in that cityscape: Portland, Oregon. An example held as the standard for modern, efficient mass transit in urban areas. (more…)
