So, so what were the fuels and technology that were increasing in 2025?
2:54
Well, as I said, you know, we saw all, uh, fuels and technologies increasing over the course of 2025, uh, but at different rates.
3:03
Um, and if we break that down a little bit, uh, we can look at, uh, fossil fuels first, and what we see there is that for natural gas, um, that was the largest contributor amongst fossil fuels to the overall increase in energy demand that we saw in 2025.
3:17
So, um, more than 15% or around one-sixth of the total increase, uh, came from natural gas.
3:22
But in fact, looking across oil, coal, and natural gas, uh, demand for each of those increased in 2025, reflecting their continued importance in the global energy system.
3:33
But in each case, it did so more slowly than what we'd seen, um, over recent years.
3:37
Uh, the other part of this i- is to consider, um, how these fuels contributed alongside low emission sources of energy, if I can call them that.
