Radioactive coal

This just in, from Scientific American:

[T]he waste produced by coal plants is actually more radioactive than that generated by their nuclear counterparts. In fact, the fly ash emitted by a power plant—a by-product from burning coal for electricity—carries into the surrounding environment 100 times more radiation than a nuclear power plant producing the same amount of energy.

At issue is coal's content of uranium and thorium, both radioactive elements. They occur in such trace amounts in natural, or "whole," coal that they aren't a problem. But when coal is burned into fly ash, uranium and thorium are concentrated at up to 10 times their original levels. Fly ash uranium sometimes leaches into the soil and water surrounding a coal plant, affecting cropland and, in turn, food . . . [E]stimated radiation doses ingested by people living near the coal plants were equal to or higher than doses for people living around the nuclear facilities.

Not that the risk of radiation from either coal plants or nuclear power plants appears to be significant for those living nearby.

The twelve countries with the highest quality of life

The twelve countries with the highest quality of life do not include the United States. We come in at number 13, which means that we''re not doing badly as a whole. But we're not doing as well as we should be doing, assuming (as many conservatives insist without reference to any metric) that there is no greater country than the United States. We were beaten in the rankings by many "socialist" countries, such as Norway, Canada, Sweden and France. The U.N.'s measurement system is the Human Development Index, a complex objective formula, not a subjective determination. Some of the many dozens of factors that go into the HDI include the following:

  • Adult illiteracy rate
  • Asylum seekers by country of asylum
  • Average annual change in consumer price index (%)
  • Children underweight for age (% under age 5)
  • Combined gross enrolment ratio in education (%)
  • Earned income (estimated), ratio of female to male
  • Female adult literacy rate (% aged 15 and above)
  • Female estimated earned income (PPP US$)
  • Female life expectancy at birth (years)
  • GDI rank
  • GDP per capita (PPP US$)
  • Government expenditure on health as a percentage of total government expenditure
  • Government expenditure on health per capita (PPP US$)
  • Healthy life expectancy at birth (years)
  • Human development index value
  • Human poverty index (HPI-1) rank
Consider, also, this recent news from the Commonwealth Fund:

Although the United States now spends $2.4 trillion a year on medical care — vastly more per capita than comparable countries — the nation ranks near the bottom on premature deaths caused by illnesses such as diabetes, epilepsy, stroke, influenza, ulcers and pneumonia

Maher: American is the land of get nothing done

Bill Maher is distressed about America's lack of capacity to do good things and stop doing bad things. Our mechanism for meaningful change is completely broken.

Well, I hate to be a nudge, but why has America become a nation that can't make anything bad end, like wars, farm subsidies, our oil addiction, the drug war, useless weapons programs - oh, and there's still 60,000 troops in Germany - and can't make anything good start, like health care reform, immigration reform, rebuilding infrastructure. Even when we address something, the plan can never start until years down the road. Congress's climate change bill mandates a 17% cut in greenhouse gas emissions... by 2020! Fellas, slow down, where's the fire? Oh yeah, it's where I live, engulfing the entire western part of the United States! We might pass new mileage standards, but even if we do, they wouldn't start until 2016.
What do we need?
a) leaders with balls, and b) a general populace who can think again. Barack Obama has said, "If we were starting from scratch, then a single-payer system would probably make sense." So let's start from scratch.
I find Bill Maher to be especially insightful--he cuts right through the BS over and over. This particular article by Maher was especially well written.

Friedman: It’s time for a gas tax, but we don’t have the guts.

According to Thomas Friedman's recent op-ed in the NYT, given that oil prices are way down compared to last year, it's time for a gas tax, but we don't have the guts. We don't have the guts to make hard decisions like France and Denmark, which have both dramatically reduced their dependency on petroleum. Further, a gas tax would also generate much-needed revenue.

Such a tax would make our economy healthier by reducing the deficit, by stimulating the renewable energy industry, by strengthening the dollar through shrinking oil imports and by helping to shift the burden of health care away from business to government so our companies can compete better globally. Such a tax would make our population healthier by expanding health care and reducing emissions. Such a tax would make our national-security healthier by shrinking our dependence on oil from countries that have drawn a bull’s-eye on our backs and by increasing our leverage over petro-dictators, like those in Iran, Russia and Venezuela, through shrinking their oil incomes.

To get serious about sustainability, move back to the city.

According to Witold Rybczynski (writing in The Atlantic), it's time to get serious about living sustainably. Currently, we do that by going out to buy the latest and greatest gadgets for saving energy. There's a much better foundation for accomplishing this goal of living sustainably:

The problem in the sustainability campaign is that a basic truth has been lost, or at least concealed. Rather than trying to change behavior to actually reduce carbon emissions, politicians and entrepreneurs have sold greening to the public as a kind of accessorizing. Keep doing what you’re doing, goes the message. Just add a solar panel, a wind turbine, a hybrid engine, whatever. But a solar-heated house in the burbs is still a house in the burbs, and if you have to drive to it, even in a Prius, it’s hardly green.
Instead of putting little Band-Aids on the big problem, Rybczynski argues that we ought to move back to the city. We would save much more energy by prohibiting spread-out low-rise buildings than by pasting solar panels on them. "A reasonably well-built and well insulated multifamily building is inherently more sustainable than a detached house." He advocates three or four story "walk-ups," which don't require elevators. These can create sufficient density "about 50 people per acre, to support public transit, walk ability and other urban amenities." Another important approach is to focus on the way we construct our commercial buildings. When we combine residences with commercial and institutional structures, buildings consume 48% of our energy, more than any other sector.
