Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. In the journal Joule , Harvard researchers report the most accurate modelling yet of how increasing wind power would affect climate.

Ninth annual Green Innovation Index finds California light-duty vehicle emissions spike; major challenge to 2030 climate goals

Green Car Congress

Both rail and bus emissions decreased during this time, due in part to the state’s efforts to transition to cleaner fuels and to electrify public transportation. The decade-long nationwide slide in emissions from power production reflects the electric power sector shifting away from coal and toward less carbon-intensive fuels.
