Stanford energy experts agree that the world needs to move decisively to a low-carbon energy system. On the road to that future, barriers must be scaled; mysteries, unraveled. The prospect is remaking the world’s largest economic sector—energy—to be more sustainable, secure and affordable for everyone.
Coal, oil and natural gas are burned to warm our homes, charge our devices and power our cars. These fossil fuels supply 80 percent of the world’s energy use and are the primary human source of greenhouse gas emissions. Our use of energy has become enormously more efficient over the past 50 years, but the associated reduction in emissions has been overwhelmed by global economic growth. Most people agree that cutting our reliance on fossil fuels would have many benefits, but what will replace them and continue economic growth?
Wind and solar are increasingly popular sources of energy, but the sun does not always shine, nor the wind blow. Batteries to store their intermittent energy are not yet cheap and powerful enough to fill the gaps. Nuclear energy produces no greenhouse gases directly, but the current generation of reactors has other problems. Solutions like storing carbon dioxide underground or turning it into clean fuel are promising, but they also need much development. The list of possibilities goes on.
In ten short videos, Stanford researchers describe how, among these many developing options, they envision the world arriving at our green energy destiny. Nobel physicist and former U.S. Secretary of Energy Steven Chu outlines the broad challenge, “which cannot be overestimated.” Other professors describe pathways to better technologies, as well as the public policies and financial mechanisms necessary for the best applications to flourish. All agree that the goal is a decarbonized energy system, and that a symphony of solutions—rather than one instrument—likely will create that future.
