How the crisis is reshaping energy investment
…report projects that global energy investment will reach $3.4 trillion in 2026, a slight increase year-on-year. Around $2.2 trillion is expected to go towards grids, storage, low-emissions fuels, nuclear, renewables, efficiency and electrification in 2026, while around $1.2 trillion is set to be invested in oil, natural gas and coal.
Despite higher oil prices, oil investment is expected to decline for a third consecutive year in 2026. The report finds that uncertainty over the duration of the price spike, long project lead times, supply chain constraints and tighter offshore rig markets are limiting near… -
