A fresh look at LED lighting challenges ideas as to whether it’s better for the environment. A recent piece published by Gizmodo argues that the benefits of LED lighting – energy efficiency and reduced costs – could lead to more lighting overall. It’s called the rebound effect, and there’s disagreement over the impact it may have. Some scientists say that concerns about the rebound effect are overblown. They argue that more efficient technology reduces threats to the environment; so, even if the world is getting brighter, it’s become brighter using less energy.
We break down the facts, and look at common household items and their impact on climate. Our guests:
