Want to make a difference in something important? How about the planet? That’s pretty important. Here’s an interesting article from researchers in the UK who nicely summarize four broad ways in which computing can help us build a sustainable future: optimizing the digital infrastructure to achieve maximum energy efficiency, developing a global data collection network for sensing and optimizing resource consumption and environmental impact, forecasting and responding to future events in natural systems, and finding digital alternatives to physical activities. We need lots of smart, creative, motivated young people to make this happen!
