BUT in March 2025 the IEA updated the data
Showing in 2024 this was just 50% (7EJ / 14EJ)
This significantly changes the trend
& previous years of data suggest that the % was higher in the past i.e. the trend is probably long term decline, not reflected by the TBI's report.

Primary energy is a measure of how much energy is directly available in the source (e.g. coal, oil, wind) before it is converted into useful energy
The key thing is that 2/3rds of fossil fuel primary energy is lost e.g. as heat.
For renewables, this is much less; 90% of primary energy ends up as useful end-use energy
So comparing primary energy in this way is not the whole story.
And using primary energy, which has been debunked numerous times, is not the whole story:
