Do you have some numbers on if you recycle vs not doing it?
There is a major difference here.

And: you give some numbers in US units and some in SI units. So when you speak about tons, are we talking metrical tons or US tons?

Nice post anyway

This seems like a timely story to add to the discussion.

Belching moose add to global warming

quote:

OSLO (AFP) - A grown moose belches out methane gas equivalent to 2,100 kilograms (4,630 pounds) of carbon dioxide a year, contributing to global warming, Norwegian researchers said Wednesday.

That is more than twice the amount of CO2 emitted on a round-trip flight across the Atlantic Ocean from Oslo to the Chilean capital Santiago, according to Scandinavian Airlines.

Articles like this drive me crazy. It may all be perfectly factual, but isn't it a bit suspicious that some unknown Norwegian "researchers" find out moose are killing the environment and then the follow-up paragraph contains some data from Scandinavian Airlines discussing how moose are worse for the environment then flying? Just who funded this research anyway?

All that aside, we really should kill of the moose.

Good find.

Maybe we can ride the moose around the world instead of flying. That might take a few years off their lives too...

Hehe, i read that story in the norwegian media. It was actually something the scientist in your linked article had written in a blog as a humorous point before the yearly moose hunting. Somehow a journalist in the largest tabloid in Norway thought this was a good case to write about

The one thing I did want to bring into it was the electricity, since it turns out this is the only one I've actually researched in detail. It varies a lot depending on where you live, but the average kWh generated in my province creates 0.985 kg (2.17lbs), more than double your number. A quick glance at google seems to put the US nationwide average at 1.35lbs/kWh.

The 0.95 lbs per kwh was a number I was seeing around a lot. But, more importantly I saw a calculation that incorporated various percentages of energy sources (coal, gas, a little wind, etc), then calculated the relative BTUs they produced, threw in the efficiencies of the processes, and actually came up with a similar number. And, at the time that seemed pretty reasonable to me.

But, you bring up a very good point. For the US there is a State by State analysis here

And being Californian (at times) my numbers are actually around 0.61 lbs. So, I guess in addition to the weather I am entitled to use up over 3 times more energy than you guilt free

What is half of nine? An irrational number!

Actually, I am pretty sure its still a rational number

US tons.

Actually, I think the only number that is metric is in reference to a gas. My feeble mind can only think of gases in liters. You know that old PV=nRT crap.

Well, as long as California isn't importing any power at the time you're using it. Those are both numbers based on what's generated locally. If you're pulling power from out of state, we are on the same grid. Otherwise, we could solve global warming by relocating everyone to Idaho.

I don't believe thats entirely true. California imports its extra energy demand up via the Northwest. I don't believe that extends all the way up to Edmonton. We actually have a hard enough time establishing contracts with the Northwest USA for them to send power down to us. It's not all free-flowing love on the grid. On a side note, at one time there was some discussions to import energy from Wyoming but I believe it was nixed. I think California may have some regulatory requirements for a certain level of "clean" electricity that it imports, and if not, its certainly the direction its heading.

Well, the western grid includes both Alberta and California, so what I said is, at least on a technical level, correct. They are interconnected. Whether California actually has any contracts to buy power from this far away is another story, and one I would have no idea about.
