Quadruple renewables to limit climate change




Meeting the goals of limiting climate change set by the international community requires, among other things, quadrupling the annual rate of increase in the deployment of electricity from solar and wind sources by 2030.

This is one of the 25 recommendations included in the first official evaluation report commissioned by the 45 countries that committed on the Glasgow COP26 in 2021 for clean technologies to be the most affordable, accessible and attractive option in the main carbon dioxide (CO2) emitting sectors at the beginning of the next decade.

In the past decade, the ability to electricity generation from renewables increased by 130%, while non-renewable sources rose 24%.

The International Energy Agency (IEA), the International Renewable Energy Agency (Irena) and the UN High-Level Champions for Climate Change, authors of the report, consider that by 2030 the world needs to incorporate an additional 630 gigawatts of solar energy and 30 gigawatts of wind power.

Renewable capacities will rise by 8%

According to his calculations, renewable capacities will rise by 8% this year to 300 gigawatts, which in total is equivalent to what is needed to supply some 225 million homes.

Another of the main recommendations addressed to the leaders participating in the Global Action Forum for Clean Energy to be held in the US city of Pittsburgh this Wednesday and Thursday, is to set deadlines for the marketing of new vehicles that emit CO2.

Specifically, his proposal consists of do not allow the sale of cars and new vans with thermal engines from 2035 (when this obligation is already expected to be imposed in the European Union) and also oblige that from 2040 only zero-emission trucks go on the market.

Last year, a record 6.6 million electric vehicles were sold in the world, double the number in 2020. They represented around 9% of the world total.

The production of green hydrogen would have to rise to about 150 million

In order to respect the international objectives of global warming limited to 1.5 degrees centigradethat market share would have to rise to 60% in 2030, which would require multiplying by ten the recharging infrastructures for electric vehicles.

The production of the call green hydrogen (generated with renewable sources) and hydrogen with low CO2 emissions would have to rise from less than 1 million tons in 2020 to about 150 million in 2030.

In the steel industry, the priority would be to move from currently 1 million tons of low-carbon steel per year to about 100 million tons at the beginning of the next decade. That would imply a 30% reduction in emissions intensity.

The authors of the study also set a series of goals for the agricultural sector, which supposes around 20% of global emissions causes of global warming.

In that case, it would be about increasing yields while stopping the expansion of cropland and grazing land to stop deforestation.

The executive director of the IEA, Fatih Birol, has insisted that “only by accelerating the transition to sustainable clean energy” can “energy security” be achieved, at a time when the world is experiencing “the first truly global energy crisis” .

85 million new jobs

Birol stressed the importance of international cooperation that will allow this transition to be “faster, cheaper and easier for the whole world.”

“Without this collaboration,” he warned, “the transition to net zero emissions will be much more complicated and could be delayed for decades.”

According to the organizations involved in this study, international cooperation can contribute to making the costs of some technologies clean waters will decrease by 18% by 2030.

In addition, the energy transition to align with the objective of global warming limited to 1.5 degrees Celsius would allow the creation of 85 million new jobs in that horizon from 2019, which would compensate for the 12 million jobs that would disappear by the same process.
