Benefits, limitations and risks of artificial photosystems
- Judging an artificial photosystem means weighing its benefits to society and the environment against its limitations and risks, and asking how green it is compared with other energy sources.
- A source counts as green when it is renewable without limit and does little damage to ecosystems while it runs.
- Evidence on cost, efficiency and environmental harm should decide how much support a technology deserves.
- Deciding whether a panel should fund large-scale artificial leaves by comparing costs, gains and environmental harm with existing sources.
