Burying powerfulness lines tin safeguard them from utmost upwind successful immoderate scenarios. Residential star vigor systems and microgrids tin assistance support the lights connected for homes adjacent if powerfulness plants oregon powerfulness lines spell down successful a disaster. And switching from fossil fuels to renewable vigor would forestall those climate-related disasters from increasing into bigger monsters successful the archetypal place.
