Ok, let's do a Fermi-like estimation. Estimates on the number of deaths related to coal generation vary from around 13,00 to 30,000 per year in the US [1] and 500,000 per year in China [2]. The current world population is 7.6 billion, of which the US and China account for approximately 1.8 billion people. Let's round the coal-related death rate way down for easy math: 10,000 per year in the US and 100,000 per year in China. Then, multiply that rate by the world's population, and you have, let's say 450,000 coal-related deaths per year worldwide. This is a really squishy number, but we only need approximations here. You were concerned about how many people would die every hundred years from nuclear disasters, so let's see if we can work today's 450,000 per year estimated deaths backwards for the last hundred years. The world population was somewhere in the neighborhood of 1.8 billion people in 1917. Assuming linear growth (I know, I know) and a strong r-value correlation for population vs. coal-related deaths (arguable, but again, Fermi estimate), we have to sum .00006 * population from 1.8 billion -> 7.6 billion, and we end up with approximately 28 million people. Which is to say, if we could gather up all the deaths, worldwide, from coal, over the last hundred years, and convert it into a single disaster, it would kill the entire city of Shanghai, and New York for the apple on top. That would have to be one hell of a nuclear disaster. Now, there are arguments to be made that the energy we've received from coal has also powered hospitals and technology which have saved or improved people's lives. There are also arguments to be made that the side-effects of coal (hospitalization, environmental disasters) cause the death toll to absolutely pale by comparison. And again, I've rounded these numbers down at every stage of the calculation. [1]: http://www.catf.us/resources/publications/files/The_Toll_fro... [pdf]; it includes its own numbers, at the 13,000 estimate, and the EPA's, at 14,000 to 36,000 range. [2]: https://www.nextbigfuture.com/2011/03/deaths-per-twh-by-ener... (blog, but includes lots of supporting links; I'm open to alternative sources that give vastly different estimates). |
Even ignoring renewables, gas solves many of the worst problems with coal.
