Thanks to the University of Minnesota for sponsoring this video! http://twin-cities.umn.edu/ The way smartphones made many devices nonessential is a model for a new way to think about improving energy efficiency. Thanks also to our Patreon patrons https://www.patreon.com/MinuteEarth and our YouTube members. ___________________________________________ To learn more, start your googling with these keywords: Dematerialization - using less (or no) material to deliver the same serviceEnergy conservation - using less energy by adjusting behavior (turning down your heat)Energy efficiency - using less energy by using technology that requires less energy to perform the same function (insulating your house to keep warm while using less energy)Energy intensity - energy consumption per unit of GDP (reduced by increasing energy efficiency)Energy services - the useful functions you're able to perform by using energy (what we refer to as ‘function’) ___________________________________________ If you liked this week’s video, you might also like: Phones are great for the environment https://www.wired.com/story/iphone-environment-consumption/ Nope, phones are bad for the environment https://theconversation.com/how-smartphones-are-heating-up-the-planet-92793 Amory Lovins on ‘integrative design’ (watch the video abstract) - https://iopscience.iop.org/article/10.1088/1748-9326/aad965/meta The US would use 85% more energy if it weren’t for efficiency efforts since the 1970s https://thehill.com/blogs/congress-blog/energy-environment/308170-cheap-clean-and-easily-accessible-an-energy-resource US energy intensity has halved since 1970 https://www.eia.gov/todayinenergy/detail.php?id=10191 This chart shows just how much energy the US is wasting https://www.weforum.org/agenda/2018/05/visualizing-u-s-energy-consumption-in-one-chart _________________________________________ Subscribe to MinuteEarth on YouTube: Support us on Patreon: And visit our website: https://www.minuteearth.com/ Say hello on Facebook: http://goo.gl/FpAvo6 And Twitter: http://goo.gl/Y1aWVC And download our videos on itunes: https://goo.gl/sfwS6n ___________________________________________ Credits (and Twitter handles): Script Writer, Editor and Video Narrator: Alex Reich (@alexhreich) Video Illustrator: Sarah Berman (@sarahjberman) Video Director: David Goldenberg (@dgoldenberg) With Contributions From: Henry Reich, Kate Yoshida, Ever Salazar, Peter Reich, Julián Gómez, Arcadi Garcia Music by: Nathaniel Schroeder: ___________________________________________ References: Belkhir, L., & Elmeligi, A. 2018.
