Without investment, the energy transition would still be little more than a pipe dream.
According to the IEA, around US$2.2tn was invested in renewables, nuclear energy, grids, storage, low-carbon fuels, efficiency measures and electrification in 2025.
For context, that was twice as much as the US$1.1tn spent on fossil fuels during the same period.
With such a large amount of capital being funnelled into climate technology, the story of the investors at the heart of the transition is fascinating.
One of the UK's largest transition investors right now is Foresight Group, a London-based investment firm which has £13bn (US$17.4bn) of assets currently under management.
