New report on massive growth of renewables last year

Climate Progress is the title of my blog posts' main home, as much as the "progress" part strains credulity at times. I only see two major quantitative areas of sustained progress: clean energy deployment (especially in Europe) and private sector clean-tech funding.

Those folk at Clean Edge, who wrote the best 2007 book on clean tech, The Clean Tech Revolution, have quantified these gains -- and made predictions about the future -- in a new report you can read here. Some interesting factoids:

Please don’t use incandescent bulbs for heating

Please.

As Andrew Leonard writes in his "How the World Works" blog, this all began with a column by ...

Toronto Star energy reporter Tyler Hamilton that itself had summarized the conclusions of a study raising questions about whether it always makes sense to replace incandescent light bulbs with CFLs. The nub of the argument was that in some cases the heat generated by the incandescent light bulbs could be useful.

Tyler is a friend of mine and a great reporter, so I sent him an email explaining why this is not true, which was not written for publication. Then Leonard himself summarized the column on his blog. So, as Leonard explains:

A factor of 3.67 makes a big difference when discussing climate

The biggest source of confusion and errors in climate discussions probably concerns "carbon" versus "carbon dioxide." I was reminded of this last week when I saw an analysis done for a major environmental group that confused the two and hence was wrong by a large factor (3.67). The paragraph I usually include in my writing:

Some people use carbon rather than carbon dioxide as a metric. The fraction of carbon in carbon dioxide is the ratio of their weights. The atomic weight of carbon is 12 atomic mass units, while the weight of carbon dioxide is 44, because it includes two oxygen atoms that each weigh 16. So, to switch from one to the other, use the formula: One ton of carbon equals 44/12 = 11/3 = 3.67 tons of carbon dioxide. Thus 11 tons of carbon dioxide equals 3 tons of carbon, and a price of $30 per ton of carbon dioxide equals a price of $110 per ton of carbon.

No American-made car meets China’s fuel standards

The Toronto Star reported an alarming factoid earlier this month:

No gasoline-powered car assembled in North America would meet China's current fuel-efficiency standard.

That's mainly because:

1. Currently, their standard is much higher than ours.
2. Their standard is a minimum-allowable efficiency standard rather than a "fleet-average" standard like ours.
3. Our lame car companies don't make their (relatively few) most efficient vehicles in this country.

As for our much-hyped new 35-mpg (average) standard -- in 2020, it will take us to where the Chinese are now (but not even to where Japan and Europe were six years ago). If we don't rescind it, that is.

So whether you believe in human-caused global warming or peak oil, America remains unprepared to capture the huge explosion in jobs this century for clean, fuel-efficient cars.

Oh, and by 2010, China will be the world leader in wind turbine manufacturing and solar photovoltaics manufacturing. No worries, though: our TV and movie sales overseas still kick butt. For now.
