Almost three years ago (on July 5, 2011) Plugged In joined the Scientific American blogging family, creating a space for exploring developments that connect us to energy, our planet and each other. The blog began with four writers – David, Melissa, Scott, and Robynne – and then grew to five when Sheril joined the team in 2013.

On Friday, Plugged In said a very fond “farewell – hasta pronto!” to David as he announced his move into a new position in the Middle East that will keep him away from wordpress (for now). A mechanical engineer from Austin, TX, David published over 200 articles on Plugged In, in addition to articles in Scientific American’s print magazine and on the Scientific American “News and Features” column.

A BIG “THANKS” to David for all of his contributions.

Today, the Plugged In writing desk is pleased to report that Tali Trigg will be joining the discussion for the next few months as a regular contributor on Plugged In. Tali is an energy analyst, technology policy advisor and writer. He has previously guest posted on Plugged In on several occasions (see - here, here, and here). Tali’s work includes research and analysis on energy and transportation, with an emphasis on the role of cities in shaping transport energy demand and mobility solutions.
