Why nighttime EV charging is incentivized while daytime is cleaner

Green Car Reports

When it comes to overall carbon emissions, EVs are cleaner than internal-combustion cars, but how much cleaner can depend on when they're charged, according to a recent Bloomberg New Energy Finance blog post. A grid more reliant on renewable energy will shrink the carbon footprint of EVs charging from it.
