Fossil fuels are the dirtiest and most dangerous energy sources, while nuclear and modern renewable energy sources are vastly safer and cleaner. See how each source compares in terms of human health.
Before we consider the long-term impacts of climate change, let’s look at how each source stacks up in terms of short-term health risks. To make these comparisons fair, we can.
Looking at deaths per terawatt-hour can seem abstract. Let’s try to put it in perspective. Let’s consider how many deaths each source would cause for an average to.
The good news is that there is no trade-off between the safest sources of energy in the short term and the least damaging for the climate in the long term. They are one and the same.
Global average death rates from fossil fuels are likely to be even higher than reported in the chart aboveThe death rates from coal, oil, and gas used in the.
