On the one hand, harnessing the power of the atom gave us the ultimate tool of destruction, but it can be an equally powerful force for good in the world—if we let it. Electricity human body By reducing our reliance on fossil fuels, nuclear energy cuts smog and harmful emissions, like benzopyrene—a well known cancer-causing agent that’s found in both cigarette smoke and coal fly-ash.

Way back in the 1970s, the United States National Research Council’s Committee on Biologic Effects of Atmospheric Pollutants released their findings in a report, Particulate Polycyclic Organic Matter. Gas up asheville The title alone is a mouthful, but the report itself contains over 300 pages of statistics and analysis on the dangers of carbon-based pollutants introduced into the environment by things like automobiles and power plants.

The big statistic from this report that I’d like you to see is found on page 224 of the document, where a linear regression analysis reveals a correlation between the rate of male lung cancer deaths and the amount of “solid fuel”—i.e. A gaseous mixture contains coal—that we burn every year. Gas vs diesel cars While statistical methods like this aren’t perfect, they’re important for helping us get a look at the big picture, and there are ways to account for those imperfections—for example, this model also takes cigarette smoking, the primary cause of lung cancer, into account.

What the regression analysis found was that, for every metric ton of coal burned per person per year—i.e. M gasbuddy for every ~315 million tons of coal burned per year in the US—there’s roughly a 20% increase in lung cancer deaths among men. Electricity voltage in china “But what about women?” you might ask—but the data’s less clear there. Q gas station cleveland ohio Women seem to be less susceptible to some types of lung cancer than men, although that seems to be changing and we’re not sure why.

But back to the numbers. Wd gaster theme In the US, coal is used primarily for the generation of electrical power, providing 38% of the juice that keeps the lights on, the refrigerator running, and your phone charged. Electricity vocabulary words The remaining 62% comes from a variety of sources: most from “natural gas”, some renewable energy like solar or wind, but third most significant source of electrical power in the US is nuclear energy, coming in at 19% of our total power supply in 2014.

But let’s say the well-intentioned but dangerously misguided ” No Nukes” movement gets their way and we legislate the US nuclear power industry out of existence. Gas relief while pregnant So now there’s a gap of 19% between the grid’s demand for energy and the amount that’s being produced. Gasbuddy app Assuming the other sources grow proportionally to fill that gap, coal suddenly has to provide 47% of the nation’s electricity needs, since 81% of the US’s current electrical power is non-nuclear, and coal makes up 47% of that 81.

Now it’s time to talk kilowatts. Electricity symbols worksheet In 2014, we used 4.147 trillion kilowatt-hours (kWh) of electrical energy as a nation. Kansas gas service bill pay 38% of that came from coal, but if we’d had to do without nuclear? An additional 9% of that juice—373 billion kilowatt-hours—would likely have come from coal. La gasolina daddy yankee mp3 According to this resource, it takes 1.04 lb of coal to generate one kWh of power, which works out to 2120 kWh of energy generated for every metric ton of coal burnt (if you’re following along to check our math at home, the linked resource uses “ton” to mean “short ton”, which is 2000 lbs, rather than “metric ton”, a.k.a. Electricity around the world “tonne”, which is 1000 kg. Electricity history in india It’s terrible, I know). Gasoline p So to get that extra 373 billion kWh, we’d have to burn an extra 176 million metric tons of coal every year.

Let’s take another look at the units on that statistic from the National Academy of Sciences—a 20% increase in male lung cancer deaths for every ton of coal burnt per person per year. Electricity merit badge worksheet With a population of 319 million, that 176 million ton offset thanks to nuclear energy works out to 0.55 tons of coal per person per year. U gas hampton That corresponds to an 11% increase in male lung cancer deaths.

So how many lives is that? 158,000 people are expected to die of lung cancer in the US this year, and men make up about 60% of all lung cancer deaths in the US. Electricity receiver definition 60% of 158,000 is 94,800, 11% of which is about 10,400—and there’s our final answer. Youtube gas laws Keep in mind that this is something of a conservative estimate, assuming that only men are influenced by the environmental by-products of fossil fuel use.

How does that stack up next to the dangers of nuclear energy? Obviously it’s no good to say “coal kills people, let’s use nuclear instead” if nuclear is going to kill just as many people—but the simple fact is that it doesn’t. Electricity lab activities During ordinary operating conditions, nuclear energy releases nothing but steam into the environment. Electricity and magnetism online games Even in catastrophic scenarios, the death tolls associated with nuclear energy are paltry compared to the number of deaths prevented by curtailing emissions of toxic chemicals. Gas out game commercial While there’s an enormous amount of misinformation* out there, the World Health Organization has estimated the cumulative casualty total for Chernobyl—the deadliest nuclear accident in history—at around 4,000. Electricity omd That means, at current levels of energy production, we could afford two Chernobyl-scale accidents every year in the US alone and we’d still be coming out ahead in terms of lives claimed by the nation’s energy infrastructure.

Now obviously it’d be ideal to get our power from renewable sources like solar, which has a zero percent chance of killing you ( unless you’re a bird or a particularly foolhardy hang glider) but in terms of energy sources that don’t depend on the weather, nuclear is clearly the safest.

*”Fake News” has been in the spotlight lately, but it’s been around for a long time. 935 gas block Wild exaggerations of the damage done by Japan’s Fukushima meltdown abound, and the same goes for Chernobyl.
