Solar energy is helping move the world’s energy production from fossil fuels to carbon-free sources. Done right, it could also offer a solution to other serious environmental problems.
Not only is the planet’s climate warming quickly, but much of Earth’s water is contaminated with nutrients, harmful algae, and chemicals that make it unsafe to drink. A million species of life are at risk of extinction, including creatures like pollinating insects that are critical to human survival.
The best ways to solve these problems are still up for debate — no matter what, big challenges will require big changes. Any strategy that can help address all these issues at once means saving valuable time and resources.
New research points to the potential of “farming electrons” to do exactly that.
