This data-file is an Excel “visualizer” for some of the key headline metrics around renewables’ share of global energy: such as total global energy use, electricity generation by source, wind penetration and solar penetration; broken down country-by-country, and showing how these metrics have changed over time, in an easy-to-compare visual format.
Global useful energy consumption stood at 71,000 TWH in 2021, rising at 2.5% per year in the past decade. It will most likely continue rising to over 100,000 TWH pa by 2050 (data here).
Electricity comprises 40% of total useful energy, with 28,000 TWH generated in 2021, and the remainder is for heat, motion, materials.
Electricity’s 40% share (as a percent of total useful energy) has changed remarkably little over the past decade, in our assessment, although electricity did increase from 15% to 17% of total primary energy.
Wind and solar now comprise 10% of all global electricity, of which two-thirds is wind, one-third is solar; making up 13.5% of OECD electricity and 8% of non-OECD.
Wind and solar’s 10% share is up from 2.3% a decade ago. This 7.7% increase has displaced coal (41% to 36%), but more disappointingly for CO2 intensity, also nuclear (12% to 10%) and hydro (16% to 15%), while natural gas remains at 22-23%.
The “renewables frontier” is that Spain, Portugal and Ireland are generating 30% of their electricity from wind and solar in 2021, followed by the UK, Germany and California at 25-30%. (Denmark has generated 50-60% from wind/solar since 2017, but this high penetration is achieved by exporting power).
Slow-downs. The ramp to 20-25% occurred more quickly in some of these countries, while the subsequent ramp to 25-30% sometimes (not always) occurred more slowly, and this may be the time that storage and demand-shifting start becoming more important.
Intermittency markets? Most countries in our screen are on course to reach 30% wind and solar penetrations within 5-10 years, again suggesting the dawn of demand-shifting, storage and intermittency solutions in this timeframe.
The cleanest grids in the world, however, belong to Norway (91% hydro, 8% wind) and Sweden (42% hydro, 31% nuclear, 16% wind), where nuclear and hydro can also buffer renewables (note here).
China, India and Indonesia together comprise c40% of global electricity and retain over c60% coal in their power mixes.
Despite rising renewables, coal-fired electricity, gas-fired electricity, total oil, coal and gas use are all making new highs in 2021-22. Our overview of China’s coal trajectory is here.
