Conferences and carbon impact

But if the cause of reducing computing’s carbon footprint excites you, recognize that conference travel is a pittance when compared to the negative climate impact of computing’s power consumption. Our research collaborators’ work of 2019 datacenter global power consumption estimates are nearly double earlier estimates—now 400 TWh! These numbers are a large multiple higher than the best projections based on 2013 data.3 There has been an important major change. These numbers are shockingly large—and worse— they are growing fast. Recent press about hyperscale cloud reveal growth rates of perhaps 40% per year.2 For more, see my broader call to action1 for computing professionals to address computing’s growing and problematic direct environmental impact. Let’s all get moving on this!
