Investment in renewable energy needs to triple by the end of the decade if the world hopes to effectively fight climate change and keep volatile energy markets under control, the International Energy Agency (IEA) has said.

“The world is not investing enough to meet its future energy needs … transition‐related spending is gradually picking up, but remains far short of what is required to meet rising demand for energy services in a sustainable way,” the IEA said in its annual World Energy Outlook released on Wednesday.

“Clear signals and direction from policy makers are essential. If the road ahead is paved only with good intentions, then it will be a bumpy ride indeed,” it added.

The Paris-based watchdog released its annual World Energy Outlook early this year to guide the United Nations COP26 climate change conference starting later this month.
It called the upcoming meeting in Glasgow, Scotland the “first test of the readiness of countries to submit new and more ambitious commitments under the 2015 Paris Agreement” and “an opportunity to provide an ‘unmistakable signal’ that accelerates the transition to clean energy worldwide”.

Need for a faster energy transition
In recent weeks, power prices surged to record levels as oil and natural gas prices hit multiyear highs and widespread energy shortages engulfed Asia, Europe and the United States. Fossil fuel demand is also recovering as governments ease curbs to contain the spread of COVID-19.

The IEA warned that renewables like solar, wind and hydropower along with bioenergy need to form a far bigger share in the rebound in energy investment after the pandemic.
Renewables will account for more than two-thirds of investment in new power capacity this year, the IEA noted, yet a sizeable gain in coal and oil use has caused the second-largest annual increase in climate change-causing CO2 emissions.

The IEA said a faster energy transition will better shield consumers in the future, because a commodity price shock would drive up costs for households 30 percent less in its most ambitious Net Zero Emissions by 2050 (NZE) scenario versus its more conservative Stated Policies Scenario (STEPS).

Will Steffen, a climate change expert at the Australian National University, told Al Jazeera the IEA report made it clear that the world needs to focus on near-term targets.

“We have to think about getting our emissions down by 2030, very rapidly and deeply. I think it’s up to nations meeting in Glasgow to galvanize action now. It’s going to require investments and policy-setting to push this transition much faster,” he said.

“Another thing that this Glasgow meeting needs to address is the transfer of funding and support from the wealthy countries to the less-developed countries to help them with their energy transition,” he added.

Status quo vs net zero
Still, the leap necessary to make good on pledges in the 2015 Paris agreement to cap the rise in temperatures to as close as possible to 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial times remains vast.

Fossil fuels – coal, natural gas and oil – made up nearly 80 percent of the world energy supply in 2020 and renewables just 12 percent.

To keep that rise near 1.5C, the IEA’s NZE prediction envisions those fossil fuels shrinking to just below a quarter of the mid-century supply mix and renewables skyrocketing to more than two-thirds.

If the world stays on its current track outlined by the STEPS scenario, temperatures will jump 2.6C (4.7F) by 2100.

The IEA foresees a peak to oil demand in all its scenarios for the first time, in the mid‐2030s in the STEPS forecast with a very gradual decline but in the NZE forecast plateauing within 10 years and dropping further by nearly three-quarters by 2050.

Doubling down on the agency’s starkest warning yet on the future of fossil fuels that it made in a May report, the IEA said its NZE picture envisioned lower demand and a rise in low emissions fuels making new oil and gas fields beyond 2021 unnecessary.

However, it did say new oilfields would be required in its two most conservative scenarios and provided tips on mitigating their climate impact like reducing methane flaring.

“Every data point showing the speed of change in energy can be countered by another showing the stubbornness of the status quo,” the IEA warned.

“Today’s energy system is not capable of meeting these challenges; a low emissions revolution is long overdue.”
