Be aware that the CO2e emissions shown in this app give an indication but have pretty big caveats:

• The CO2 emissions of nuclear that are shown are most likely too low. Electicity Maps just used the absolute lowest of a number of estimates.

• The emissions of reservoir-based hydro vary depending on climate and biomass in the reservoir but Electricity Maps uses a single standard value. Some hydro power in warmer climates is connected to methane emissions from the reservoir, because of anaerobic processes at the bottom of the reservoir. Some reservoirs emit as CO2e as a coal plant with a similar capacity. [edited slightly, see below↓]

• They are showing solar/wind emitting emissions when they're producing electricity. However, solar and wind don't work that way because they're not using consumables. Their emissions mainly come from manufacturing and transport. In essence, solar and wind are emitting just as much whether they are producing electricity or not.
