The Hidden EV Manufacturing Problem No One Talks About

Video Description

Did you know that an electric car, though much cleaner over its lifetime, actually starts out with a higher carbon footprint than a regular petrol car? This is due to the emissions-intensive processes involved in manufacturing its battery and other components. But what if we could drastically cut those initial emissions, bringing electric vehicles even closer to being fully climate-friendly from day one? Today, we’re looking at how advanced tools like virtual twins are revolutionising the manufacturing world right now. Instead of waiting decades for new tech to evolve, virtual twins allow us to make real improvements to industrial emissions immediately, especially in areas like metals manufacturing, battery production, and assembly. This is a topic we need to pay attention to because clean energy doesn’t stop at the point of use—sustainable manufacturing is key to making green tech truly green. In this video, I’ll walk you through the steps of building an electric car, highlighting how virtual twins can reduce emissions at every stage—from mining materials for the battery, to optimising metals for the car’s structure, to minimising waste on the assembly line. By the end, you’ll see how today’s smarter factories are helping to shorten the carbon payback period for EVs, pushing us toward net-zero faster.
