The 20th Anniversary Design Institute was held on March 25-26, 2021. The speakers joined us from around the globe: Canada, Brazil, Germany, Japan, and the US. Over 190 people registered for the institute, representing 22 US states and 9 countries. By going virtual, the participants saved 41.4 metric tons of greenhouse gases by eliminating travel. That is equivalent to 'charging 5,279,834 smartphones' or '7 homes' electricity use for one year'. Grateful thanks to all the speakers and participants.
