The grid. The U.S. Energy Information Administration publishes near-real-time data on the Lower 48’s electrical grid. The datasets include net electricity generation, flows in and out of the country’s various “balancing authorities,” regional demand, and forecasts of demand. You can explore the data online, access it through the EIA’s API, or download it in bulk. Helpful: The EIA’s guide to the data and “known issues”.
Pan-African surveys.

More brain scans. Last year, the Stanford Center for Reproducible Neuroscience launched OpenNeuro, “a free and open platform for analyzing and sharing neuroimaging data.” (It’s the successor to the center’s earlier initiative, OpenfMRI.) You can, for instance, download scans of brains that were watching a particular episode of The Twilight Zone.
