No we can't. We don't have EV dump trucks, excavators, bulldozers and cranes. Even if we did, the machines that mine the raw materials to build them aren't electric. The enormous concrete pads that are poured to support wind turbines emit large amounts of CO2 during the chemical process than hardens it.

I bet we're a minimum of 50 years out from having electric heavy machinery.
