You keep saying this like it’s a gotcha when even the barest level of research shows that it’s still better.
Emissions from battery production can vary wildly depending on the process used and manufacturing energy grid. According to this study, manufacturing an 80kWh battery will release between 2400kg and 16,000kg of CO2. A commercial lawnmower will have a ~20kWh battery, so in a lifetime with two batteries we’ll guess about 1200-8000kg CO2.
EPA says the average gas mower produces 88lbs of CO2 per hour of use. Over a 2000 hour commercial lifespan that’s 80,000kg of CO2. And that’s putting aside all the other pollutants and secondary emissions from maintaining a combustion engine.
Do a little research before you start your rants next time.
