Il Nuovo Postiglione - Climate goals need clean energy surge in Global South: IEA

To keep Paris climate temperature goals in play, annual investment for non-fossil fuel energy in these countries will need to jump from $260 billion to nearly $2 trillion, the intergovernmental agency said in a report.

"Financing clean energy in the emerging and developing world is the fault line of reaching international climate goals," IEA executive director Fatih Birol told journalists in a briefing Tuesday.

The report comes on the eve of the two-day Summit for a New Global Financing Pact in Paris, which seeks to galvanise support for revamping the mid-20th century architecture governing financial flows from rich to developing nations.

Speeding the transition from dirty to clean energy, and helping the Global South cope with and prepare for devastating climate impacts are high on the summit agenda.

Virtually all of the nearly 800 million people lacking electricity and the 2.4 billion without access to clean cooking fuels are in poor and emerging countries.

Under current policy trends, one third of the rise in energy use in these nations over the next decade will be met by burning fossil fuels, the main driver of global warming, the IEA warned.

"Clean energy investments is increasing gradually -- this is a good news," said Birol.

"The bad news is that more than 90 percent of that increase in clean energy since the Paris Agreement in 2015 comes from advanced economies and China."

"Only 10 percent comes from the emerging and developing countries," he added. "We need to change this trend."

- Solar is cheapest -

With China included in the calculation, private and public money pouring into renewables and other forms of carbon neutral energy will need to more than triple from $770 billion in 2022 to about $2.5 trillion per year by the early 2030s.

Investment must remain at those levels until mid-century to help keep Earth's average surface temperature "well below" two degrees Celsius, and 1.5C if possible, the Paris climate treaty's binding and aspirational targets, respectively.

The potential for rapidly ramping up renewable energy is there, according to the report.

At least 40 percent of the global solar radiation reaching the planet lands on sub-Saharan Africa, and solar energy is now the cheapest source of electricity generation across almost the entire world.

And yet, nearly ten times more solar PV capacity was installed last year in China -- some 100 GW -- than across the entire African continent.

Sunny sub-Saharan Africa generates less solar electricity than the Netherlands, Birol noted.

According to the report, two-thirds of the finance for clean energy projects in emerging and developing economies excluding China will need to come from the private sector.

Today's $135 billion in annual private financing for clean energy in these economies must rise to about a trillion a year within the next decade.

To meet both climate and sustainability goals, clean energy investment in emerging and developing economies should be concentrated in four areas, according to the IEA.

Just over a third should go into low-emissions generation, mainly solar and wind. Another third is needed to improve efficiency in end-use sectors, such as cooling and electric transport.

A quarter is required for electricity grids and storage capacity, while just under 10 percent goes to low-emission fuels and so-called carbon, capture and storage (CCS), which removes CO2 from the exhaust of gas or coal power plants and heavy industry.
