Why the Safest Form of Power Is Also the Most Feared

What do you think is the safest form of power generation? What do you think is the deadliest? According to a a 2010 study by the World Health Organization, Centers for Disease Control, and National Academy of Science, coal is the deadliest by far, killing 170,000 people per trillion kilowatt hours, or a tragic 1.964 million people per year, 500,000 of which are in China. To put that in perspective, the WHO estimates that air pollution, the primary reason for coal's high mortality rate, kills 7 million people annually.

So what is the safest form of power? One might think it's a green form of energy such as solar, wind, or hydro. This study suggests something different.
