Clean energy technologies such as wind turbines, solar panels and electric vehicles are advancing so rapidly that global fossil fuel use is now expected to peak by the mid-2020s and then start to decline, the leading agency said on Tuesday. world of energy.
But there’s a catch: The transition from coal, oil and natural gas isn’t happening fast enough to avoid dangerous levels of global warming, the agency said, unless governments take much more action. strong forces to reduce their carbon dioxide emissions that warm the planet over the next few years.
# WEO2021 is outside!
Before a crucial moment # COP26, it shows that while climate ambitions have never been so high, energy transitions still have a long way to go
Governments must give the signal that they will lead to a wave of investment in a #NetZero future

The International Energy Agency’s annual World Energy Outlook, a 386-page report that forecasts global energy trends through 2050, comes just weeks before world leaders meet for a major United Nations summit on climate in Glasgow, Scotland, to discuss how to accelerate the switch from fossil fuels and prevent the planet from overheating.
“The world has made remarkable strides in clean energy over the past decade,” said Fatih Birol, executive director of the agency, in an interview. “But there is still so much to do. “
The new report finds that the world has made significant progress in tackling climate change. Wind and solar power is the cheapest new source of electricity in most markets and is growing rapidly. Sales of electric vehicles around the world hit record highs last year. Around the world, approvals of new coal-fired power plants, a major source of emissions, have slowed dramatically in recent years, with governments and banks increasingly refusing to finance them.
As a pivotal moment in # COP26 approaches, the @OUCH warns that the crucial and inevitable transition to clean energy is underway, but that it is still far too slow to protect the world from the worst impacts of global warming. # WEO21 https://t.co/xISuvoRO23

Governments are also stepping up their policies to reduce emissions. The European Union has increased the price it imposes on major polluters to emit carbon dioxide. India has increased efficiency standards for new air conditioners. China has said it will stop funding new coal-fired power plants abroad.
As a result, the International Energy Agency now predicts that humanity’s carbon dioxide emissions will peak in the mid-2020s and then slowly decline over the following decades. Global coal consumption is expected to decline by 2050, despite a slight increase this year due to increased industrial activity in China, while global demand for oil is expected to decline permanently by the 2030s, as people switch to electricity to power their cars.
That alone would be a remarkable change. Since World War II, global carbon dioxide emissions have followed a seemingly inexorable upward trajectory, with only temporary declines during recessions, as the world depended on ever-increasing amounts of fossil fuels to power homes, cars. and factories. A turning point is now in sight, says the report.
Even so, this change is still far from enough to avert some of the most perilous consequences of climate change, the agency warned.
Current energy policies will still put the world on track to warm to about 2.6 degrees Celsius by 2100 from pre-industrial levels, according to the report. Last month, the United Nations warned that such an outcome would be “catastrophic,” noting that countries already face much higher risks of deadly heatwaves, droughts, floods and wildfires after just 1.1 degrees Celsius of global warming to date.
Many world leaders hope to limit average global warming to around 1.5 degrees Celsius to avoid some of the most serious and irreversible risks of climate change, such as widespread crop failures or the collapse of ecosystems.
Achieving this goal will not be enough for global emissions to simply peak and then decline slowly over the coming decades, as they are currently on track to do, the International Energy Agency said. Instead, the nations of the world should act much faster to cut emissions by nearly half this decade and completely stop adding carbon dioxide to the atmosphere by about 2050.
Earlier this year, the agency presented a detailed roadmap on what such an effort might look like. By 2030, for example, electric vehicles are expected to account for more than half of new car sales worldwide, compared to just 5% today. By 2035, rich countries are expected to shut down virtually all fossil-fueled power plants in favor of cleaner technologies like wind, solar or nuclear power. By 2040, all of the world’s remaining coal-fired power plants will need to be retired or upgraded with technology to capture and bury their carbon emissions.
Nations are expected to triple their investments in clean energy over the next decade, to around $ 4 trillion a year, the agency said. Most of this increase in spending is expected to go to developing countries, which have been responsible for most of the growth in emissions in recent years, but have often struggled to access finance.
“So far, only around 20% of clean energy investment goes to emerging countries,” Birol said. “This has to change. It’s a race no one wins unless everyone finishes the race.
The report notes that many countries are considering more aggressive action, at least on paper. More than 50 countries, including China and the United States as well as the European Union, have now announced targets to reach “net zero” – that is, to reach the point where they do not add more. carbon dioxide in the atmosphere – over the next few decades.
If every country kept that promise, the world could potentially limit total global warming to around 2.1 degrees Celsius by 2100, according to the report. But even this outcome is far from assured, as most countries that commit to achieving net zero have yet to adopt policies to achieve these goals.
