At the top, you’ll find the current grid status. If it says something like “Carbon‑Heavy,” that means fossil fuels are dominating the mix at the moment. Right below that, you’ll see a short note telling you when cleaner energy is expected, such as “Grid will be green in 2 hours.” It’s a simple cue that helps you decide whether to plug in now or wait a bit.

The weekly calendar is where things get really practical. It’s color‑coded so you can spot the best charging windows at a glance:

• Green Day = Good daytime charging
• Green Night = Good nighttime charging
• Gray = Times to avoid charging if you want the lowest emissions

Each day is split into “Day” and “Night” sections with specific time ranges. These windows are based on when the grid is expected to have the highest share of clean energy.

At the bottom, a renewable‑energy forecast shows how much total green energy (from wind and solar) are expected over the coming days. It’s a helpful way to understand why certain hours are recommended—maybe solar is peaking in the afternoon, or wind is strongest overnight.
