According to this study[0], it takes about 116 kWh of input energy to create a 100 kWh battery, given the materials. The majority of the total energy usage is in material production, not battery production. Assuming Tesla is not making their own materials, this deflates the required input energy substantially.

- ars 11y ago> Assuming Tesla is not making their own materials, this deflates the required input energy substantially. And also inflates that amount of greenwashing involved...... Why crow over renewable energy when your use of energy is irrelevant relative to your suppliers?
- e98cuenc 11y agoBut their statement seems accurate and clear: they will operate the GigaFactory using renewable energy. They don't claim or imply that they will extract the materials using renewable's or that all their suppliers will use renewable's.
- Gravityloss 11y agoThey should source their lithium from solar-powered contractors. Maybe even sell them some panels for a good price. (I realize the brine is already evaporated in the sun, but there's electrical separation after that.)
- Retric 11y agoA 100Kw battery is used more than once. Making it 116kwh to store 116,000+ kWh. So, your solar roof drops from 100% 'green' to 99.9% 'green' that's hardly a real issue.
- rybosome 11y agoSo the statement "our factory will produce batteries while running solely on renewable power", though potentially factually accurate, is greenwashing?
