To look at the way richer countries are spending money on the energy transition, you might think we’re within reach of bringing climate change under control.
Investment in clean energy has only accelerated in the years since COVID-19 struck. In the second half of the last decade, it grew at a 2 per cent annual rate. Since 2020, that’s risen to 12 per cent a year. This year, it will hit $US1.4 trillion ($2 trillion), the International Energy Agency wrote in its annual investment report on Wednesday, putting green power comprehensively ahead of the roughly $US1 trillion that’s being spent on fossil fuels.
If you assume those trends will continue, it looks even more promising. Just continuing to inflate existing spending at current growth rates would imply that advanced economies and China spend in the region of $US650 billion a year on clean power over the remainder of this decade, the IEA wrote — within sight of the $US850 billion-odd that’s needed to put the world on track to zero emissions by 2050.
The problem comes when you look elsewhere in the world. In emerging and developing economies (excluding China), clean power investment needs to grow at 25 per cent a year up to 2030 if it’s to hit levels consistent with net zero. In practice, spending remains stuck at the levels it was at in 2015, when the Paris Agreement was first signed.
It shouldn’t come as a surprise that there’s a dearth of funds for carbon-free power in developing countries — these nations get too little investment overall, and that lack of physical capital is one reason they’re poor.
Since the 1970s, Indian politicians have complained that only rich countries have the money to pay for pollution reductions in their lower-income peers. Prime Minister Narendra Modi’s call last year for a $US1 trillion fund from developed countries to finance his nation’s energy transition is merely the latest example of that trend. The true sum could run to $US12.4 trillion in India, with $US94.8 trillion needed for emerging markets as a whole, according to Standard Chartered.
Rich nations can green their own economies all they want. If they don’t provide the funds to repeat the trick around the world, it will all be in vain.
It’s a long-standing problem that will likely worsen in the short term. One of the advantages of renewable power in rich countries is that its expenses are almost all up-front, determined most importantly by the cost of borrowing. Finance represents about 60 per cent of project expenses for renewables, according to the IEA. Consumers of oil, gas and coal, on the other hand, have an ongoing need to buy their fuel in a volatile commodity market, making their long-term profitability highly unpredictable.
As interest rates rise, however, the cost of capital for clean power is going up as well. That’s being felt most severely in emerging markets, where the cost of capital is as much as seven times higher as it is in developed countries, and interest rates are likely to climb in tandem with the US Federal Reserve.
