Today, we consume a truly vast amount of energy - with demand continuing to skyrocket at an alarming rate.
"To respond to global warming we either need an energy supply that has no carbon release or we need to find ways to use less energy. "
—Dr Julian Allwood
We know that producing this energy has significant environmental impacts and emitting so much carbon dioxide into the atmosphere could cause catastrophic climate change. In this film, three University of Cambridge academics look at wind power, carbon capture and storage (CCS) and material efficiency as examples of how we can cut our C02 emissions. They suggest that we must act now in order to avoid the serious risks of man-made global warming, one of our greatest challenges in the 21st century.
