The percentage of energy the world is getting from fossil fuels has been decreasing gradually over the last half a century or so.

And yet.

The total quantity of fossil fuels being consumed across most of the globe keeps marching higher.

These two data sets, shown in two charts above, demonstrate the stark challenge of moving away from greenhouse gas-emitting energy sources at the same time that demand for energy keeps going up: “What’s falling is the share of primary energy from fossil fuels, not their level,” writes Michael Cembalest, chairman of market and investment strategy for J.P. Morgan Asset and Wealth Management, in his 14th annual paper on the energy markets, published in March.

The charts are based on J.P. Morgan’s updated analysis of Energy Institute data released last week.

To be sure, clean energy has been growing rapidly and non-profit energy think tank RMI projects such technologies, like wind and solar, will ultimately undercut fossil fuels due to dropping costs.

It’s a testament to the exponential growth of renewables that fossil fuels’ share of global energy consumption has not risen in recent decades even as the demand for energy around the globe has continued to climb.

The energy transition is also happening at different paces in different parts of the world.

“The progress of the transition is slow, but the big picture masks diverse energy stories playing out across different geographies,” CEO of the Energy Institute Nick Wayth said in a written statement published last week alongside the organization’s annual energy review. In wealthier economies, fossil fuel consumption may be slowing, whereas use of these fuels continues to grow in low- and middle-income economies.
