Is there anything I can do with software that would make a difference? Currently, the only things that are coming to mind are simple carbon footprint calculators or infographics/visualization of data, which imo would not be that impactful. I would love to hear ideas
"The core technologies in energy storage tend to be physics-based, but software plays essential roles in the form of design tools, simulation tools, and control systems. My favorite example is the inexplicably gorgeous Materials Project, a database and visualization tool for material properties, funded by the Department of Energy’s Vehicle Technologies Program to help invent better batteries."
It's a lengthy page with lots of good ideas, and seeds that might germinate more ideas of your own.
