Sonoma County boosts green energy infrastructure with new mobile, solar-powered EV charging stations
Sonoma County has purchased three mobile solar-powered electric vehicle charging stations to support zero-emission vehicles and mitigate ongoing climate disruption, consistent with the Climate Action and Resiliency pillar of the County’s strategic plan. The initiative is part of a larger program to replace all eligible County Fleet internal combustion engines with electric vehicles by 2030.
