Wind turbines, solar panels and electric vehicles are growing much faster than expected worldwide. However, the speed of development of this clean energy source, however fast, is not enough to reduce man-made greenhouse gas emissions.
The International Energy Agency (IEA) has concluded this in its 810-page annual ‘Global Energy Outlook’ report, which predicts global energy trends until 2040.
The report gave a serious warning about climate change, forecasting that the energy policies that countries are implementing could be the cause of global greenhouse gas emissions continue to rise in 20. Next year.
The reason is that the world’s energy cravings continue to rise and the rise of renewable energy is still not fast enough to meet all the needs that arise. As a result, the use of fossil fuels, especially natural gas, continues to increase to meet the rest of the world.
IEA CEO Fatih Birol said that without the new policy, the world will miss its climate goals. According to him, there are 5 trends in energy use that will impact our climate future.
Renewable electricity will soon surpass coal
The world’s coal consumption, the dirtiest fuel, is starting to slow. As global investment in coal-fired power plants has slowed significantly in recent years, many countries like India are also increasingly realizing that the combination of solar and storage batteries could Is a cheaper way to produce electricity.
According to the IEA’s forecast, with current policies, renewable energy such as wind, solar power and hydroelectricity will surpass coal fuel to become the dominant power generation source in the world by 2030, close Contributing to 42% of global electricity output. While coal will decrease to 34%. Natural gas, cleaner than coal but still generating a lot of emissions that heats the planet, also takes up market share of coal.
However, the IEA notes that coal is ‘far from dead’: hundreds of coal plants have been built in Asia, with an average life expectancy of only 12 years and still able to operate for decades to come. The world will be extremely difficult to quickly reduce greenhouse gas emissions, if these plants do not gradually reduce operations, such as early ‘retirement’ or equipped with more technology to handle carbon dioxide pollution and buried below. Ground. The technology to capture carbon is still very expensive.
Offshore wind develops and plays a leading role
For many years, for most countries, the installation of wind turbines on land was much cheaper. But for areas like the North European Sea, energy companies have recently installed large offshore turbines that can ‘harvest’ much more stable and stronger wind. With significantly reduced costs, this technology is becoming an increasingly attractive option for some countries.
Offshore wind currently supplies 2% of the European Union’s power; The IEA predicts this production will increase nine-fold by 2040. Companies are also planning to build large wind farms off the US, China, South Korea and Japan. If economic corporations are licensed, offshore wind could become an important tool to cut emissions in the coming years.
S.U.V series cars are eliminating the progress from electric cars
Last year, consumers around the world bought 2 million electric cars, which were made from a combination of low battery costs and generous offers in places like China and the US state of California.
The IEA predicts that the purchase of electric cars will accelerate around the world and therefore, the use of gasoline and diesel for cars globally could peak in the mid-2020s, then will decrease continuously.
However, this prediction comes with a warning that even as countries promote electric cars, more and more Americans, Europeans, Chinese and Indians are buying SUVs. ) bigger, consume more gasoline than regular cars. If in 2000, only 18% of passenger cars sold worldwide is the S.U.V line, now this figure reaches 42%.
If the ‘passion’ for the car continues, it could wipe out the effort of not using oil when developing the fledgling electric cars. The key question then was whether carmakers could figure out how to make and persuade people to buy battery-powered versions of S.U.V models. Popular.
Efforts are slowing down
In addition to switching to cleaner energy sources, countries can also limit emissions by increasing the energy efficiency of factories, homes and vehicles through policies such as Develop code and fuel economy standards.
In this regard, the IEA report says that in 2018, the energy intensity of the global economy, a measure of efficiency, only improved by 1.2%, the slowest pace in years. By. And countries that are undermining their policies, like the United States, have plans to restore standards that require more efficient use of energy.
Mr. Birol noted that today, 2 out of 3 buildings worldwide are built without energy efficiency codes or standards. While these buildings can last for 5 to 6 decades, it’s important to focus on efficiency.
Africa – the continent plays an important role in energy development
This year’s IEA report also highlights the role of Africa, which is expected to urbanize in the next few decades at a faster rate than China did in the 1990s and 2000s.
If Africa pursues a path of relying primarily on fossil fuels for development as China once did, then greenhouse gas emissions could increase significantly.
However, there are many reasons to think that African nations could point out a ‘cleaner’ path. For example, this continent accounts for about 40% of the world’s solar potential, but less than 1% of the world’s solar batteries. The energy development in Africa will surprise those who do not believe this.
