The bubbles on this map concern a country’s electricity supply and how that electricity is generated.
There are two measures available: the installed capacity, which represents the amount of electrical power a country can theoretically produce at any one time, and the electricity generated, which represents the amount of electricity actually produced that year.
These measure might differ for many reasons: perhaps a source of electricity is only operational for part of the year, for example.
Regardless of the measure used, the bubbles are coloured according to the fraction of electricity (or electrical power) that comes from renewable sources, with green tones representing more renewable electricity and brown tones representing fewer renewables:
It’s also important to note that electricity is just a small part of many countries’ greenhouse gas emissions—this map says nothing about other sources, like manufacturing, heating or the tailpipe emissions from non-electric vehicles.
The renewable electricity sources in this dataset include:
- Solar photovoltaic
- Solar thermal energy
- Onshore wind energy
- Offshore wind energy
- Renewable hydropower
- Mixed Hydro Plants
- Pumped storage
- Marine energy
- Solid biofuels
- Renewable municipal waste
- Liquid biofuels
- Biogas
- Geothermal energy
