A deeper dive into 24/7 carbon-free energy
Tech giants and startups are chasing more precise data to make the grid cleaner by the hour — and asking governments and regulators to catch up.
Jeff St. John is director of news and special projects at Canary Media. He covers the intersection of technological, economic and regulatory issues influencing the global transition to low-carbon energy in the electricity, transportation and building sectors. He is the former managing editor and senior grid edge editor of Greentech Media, and he previously reported for The Fresno Bee, the Tri-City Herald and the Anchorage Daily News. He lives in Oakland, California with his wife Tara Donoghue and his dog Lily, and enjoys hiking, gardening and playing guitar with his nieces and nephews.
His areas of expertise include renewable energy, smart grid, distributed energy resources, energy storage, demand response and electric vehicles.
He earned a master’s degree from the UC Berkeley Graduate School of Journalism in 2001.
