the future
“A zero-carbon world doesn’t have to be an awful one. The more we invest in it, the more the infrastructure around it changes to support it, and the easier and cheaper it gets… and the more normal it gets.” - Liz Keogh (@lunivore) #IBMGarage @holly_cummins
Talk about it Encourage your organisation to do more Lower your footprint Use your skills #IBMGarage @holly_cummins
The world is changing. The cloud gives us dazzling computational possibilities, and … potentially uses a lot of energy. As climate change accelerates, where do we, as engineers, fit in? Are we part of the problem or part of the solution? How do we balance the needs of people against the need of the planet? Or can they be aligned?
