The IEA also pointed to deployments in Europe and the United States, regions that are both expected to speed up renewable installations “显着地” from the previous five years.
中国, 印度, Europe and the United States together account for 80% or global renewable capacity expansion, 它说. But their current efforts alone aren’t going to solve the climate crisis.
To achieve net-zero emissions by 2050 — where the world is emitting only as much greenhouse gas as it can also remove from the atmosphere — renewable power capacity additions need to almost double in rate from 2021 至 2026, the IEA said. For biofuels, annual demand growth needs to quadruple and renewable heat demand needs to triple.
Whether global leaders are up to the task is still a question, with pledges at this month’s climate talks in Glasgow, Scotland falling short of what scientists say is needed to avoid the worst consequences of the climate crisis. 几乎 200 countries adopted the Glasgow Climate Pact at COP26 in early November, an agreement that called for the phasing down of unabated coal and inefficient fossil fuel subsidies.
While analysts said the pact was a step in the right direction
, the pledges deferred more action on reducing fossil fuel emissions to next year
To limit global warming to to
1.5 degrees Celsius — a threshold scientists say we should stay below — the world needs to cut the rate of greenhouse gas emissions by almost
27 billion metric tons a year
, according to Climate Action Tracker
. But current pledges
, including those worked out at COP26
, only get about one-quarter of the way there
India and Iran said no to including tough language about fossil fuels in the Glasgow pact. 印度, whose government recently committed to reaching 500 GW of renewable power capacity by 2030, requested a change to the text to read a phasing “down” of coal as opposed to a phasing “out.”
Coal is the dirtiest form of energy and scientists say phasing out the use of coal is key to tackling the climate crisis.
In its report, the IEA says governments need to ramp up renewables by addressing key barriers to their implementation, including grid integration, insufficient remuneration, social acceptance issues and inconsistent policy approaches.
