"Energy researcher Jessika Trancik has designed an app that helps users choose vehicles with low environmental impacts.
I’ve been an energy-systems researcher at the Massachusetts Institute of Technology in Cambridge for ten years. My research helped to guide US government strategy ahead of the Paris climate-change negotiations, and has been presented to the International Energy Agency in Paris, which helps nations to shape their energy policies.
My team and I model how electric batteries might affect fossil-fuel use, and how they are becoming more affordable and efficient. This information helps governments and policymakers to assess the effects of tax rebates on electric-vehicle purchases, for example. It also helps those considering investing in carmakers, as well as engineers who are developing road networks."
