How Much Energy Powers a Good Life? Less Than You're Using, Says a New Report

How much energy does it take to have a good and healthy life? A new Stanford University study has found that the answer is far less than the average American is using. From a report: Comparing energy use and quality of life across 140 countries, researchers found that the magic number is 75 gigajoules a year, or less. For context, one gigajoule of energy is equal to about 8 gallons of gasoline. Americans use 284 gigajoules a year per capita, nearly four times that much energy, according to the new research. "That suggests to me that we could nudge energy use downwards in a bunch of hyper-consuming countries and not just make a more equitable world, but perhaps make ourselves healthier and happier," said lead author and professor of earth system science Rob Jackson. The link between more energy and better quality of life is established. Globally, around 759 million people lived without electricity and 2.6 billion without clean cooking fuel in 2019, according to the World Bank.
