Tesla owners can now see how much solar or coal is powering their EVs Tesla owners can now see exactly what kind of energy is powering their electric vehicles. TezLab, a free app that’s like a Fitbit for a Tesla vehicle, pushed out a new feature this week that shows the energy mix — breaking down the exact types and percentages of fossil fuels and renewable energy — coming from charging locations, including Superchargers and third-party networks throughout the United States. “We’re tracking the origin of data as it relates to energy, so we know if you’re in Tucson or Brooklyn (or any location) where the energy is coming from and what the mix of that energy looks like,” Ben Schippers, the CEO and co-founder of TezLab explained in a recent interview. “As a result, we can see how much carbon is being pushed out into the atmosphere based on your charge, whether you’re charging at home, or whether you’re charging at a Supercharger.”
