Solar

Electricity from photovoltaic panels and solar thermal plants.

At this rate, one death corresponds to about 2.5 million–15 million people's annual electricity.

This scale is logarithmic: each step to the right is ten times the previous one, so the visual distance understates how much larger the fossil numbers really are.

The small grey figure under each source is the same rate turned human: roughly how many people’s yearly electricity corresponds to one death. Coal, about 700–6,000 people; solar, a few million.

The uncounted cost — priced at the central value of a statistical life ($14.1M), Solar's death toll is worth about $0.28 per MWh generated — against a market price of $46/MWh. That cost is on no electricity bill. Value of a life →

How it kills

Mainly through falls during rooftop installation and maintenance, plus accidents in panel manufacturing and transport. Like wind, there is no combustion and no pollution term.

What dominates the number

Occupational accidents — installation falls above all — dominate. Manufacturing risk is a smaller modeled share.

What the estimate does not capture

Site conditions, country-specific controls, labor practices, reliability, storage, and long-tail waste questions are outside this coefficient.
