The UK Energy Transition Commission said in its recent report that in order to move to a clean, zero-emissions planet by 2050, investment in the energy transition has to increase to $3.5 trillion a year. A huge amount of money will go towards building more wind and solar power generation capacity, while part of the total amount will go towards building infrastructure, battery storage and seasonal storage.
The commission estimates that the amount to be spent will hit $1 trillion a year, with payments reaching $300 billion a year by 2030. However, part of this amount is likely to be offset by an impending reduction in oil and gas investments of up to $500 billion a year.
The offsetting amount would reduce annual global investment spending by $3 billion, and would equal 1.3% of global GDP over the next 30 years.
