La despesa global en la transició a l'energia baixa-de carboni va augmentar més d'una quarta part el 2021, impulsada pels sectors dels vehicles elèctrics i les energies renovables.
Total investment reached 755 billion, a jump of 27 percent from a year earlier, according to a new report from BloombergNEF. The record-breaking figures show how strong investor appetite is for the technologies that are key to preventing the worst effects of global warming.
However, spending must ramp up significantly to reach net-zero carbon emissions by the middle of the century. BNEF estimates that 2.1 trillion of investment is needed in the energy transition from 2022-25, nearly three times last year's level. The figures include spending on renewable electricity, electrified heat, energy storage and nuclear power.

"Across all regions we need to see much more investment," said Albert Cheung, head of analysis at BNEF. "You're going to have to see a huge uplift and that's going to have to be driven by government policy."
La major part de la despesa el 2021 es va destinar a nous projectes d'energies renovables, com ara parcs eòlics i parcs solars. El sector va atreure 366.000 milions, un 6,5 per cent més que l'any anterior, la majoria dels quals es va concentrar a Àsia. A Amèrica, Europa, Orient Mitjà i Àfrica, la inversió en energies renovables va ser plana en comparació amb el 2020.
Renewable energy capacity will need to grow rapidly to provide enough clean power to not only displace fossil fuels from the world's electric grids, but also support new sources of demand from electric vehicles.
Investment in electrified transportation, including vehicles and supporting infrastructure, rose 77 percent in 2021 to 273 billion. This year, BNEF expects that figure to rise even further, surpassing the amount spent on renewable energy.
