How is wind and solar energy creating a significant impact on global electricity demand?
According to a report from climate and energy think tank Ember, solar and wind energy contributed toward 10% of global electricity share last year, a milestone which is accomplished by a 23% growth in solar generation and a 14% increase in wind.
Since 2015, when the Paris climate agreement was signed, the share derived from wind and sun has more than doubled. Fifty countries have now passed the 10% solar and wind milestone, with 7 latest countries joining them in 2021: Japan, China, Mongolia, Argentina, Vietnam, El Salvador, and Hungary. The Australia, Netherlands, and Vietnam were the countries with the fastest transitions to solar and wind. In the last two years, all 3 countries shifted a 10th of its electricity requirements from the old fossils to clean sources.
“Solar and wind energy have arrived. This is just the beginning of the way people, businesses, and governments in several countries are transforming into cleaner and renewable energy sources. In the Worldwide Electricity Review 2022 study, Dave Jones, global lead of Ember, said, “They need to be deployed at lightning speed this decade to reverse global emissions growth and confront climate change.” The third annual report from Ember, released on March 30, promises to provide the most transparent and up-to-date summary of changes in the global electrical transition in 2021. This energy transition will help in reducing environmental issues (producing low carbon emissions) and enhance the proper implementation of environmental management solutions at various organizations.
Electricity demand recovered, increasing by the most in absolute terms ever: 1,414 TWh between 2020 and 2021, roughly the equivalent of adding a new India to the world’s electricity demands. Demand growth in 2021 was +5.4 percent, the fastest since 2010. After falling in 2020, many advanced economies recovered to pre-pandemic levels. However, the real growth was in Asia, owing largely to economic growth; China saw the greatest increase, with 13 percent higher demand in 2021 than in 2019.
The research also mentioned that other clean energy sources – such as nuclear, hydro (hydraulic turbine), and bioenergy including solar and wind, contributed a total of 38% of the world’s electricity in 2021, the coal power also showed a remarkable rise. Also, global energy industry investments are predicted to increase in future years. With the increase in offshore wind energy investments, the demand for wind turbine, floating wind turbine, etc. is in demand (history of wind turbines).
However, coal power increased by 9% in 2021 to 10,042 TWh, a new all-time record, according to the research. Despite the fact that worldwide electricity demand increased by 1,414 TWh from 2020 to 2021, solar and wind barely met 29% of that growth. The rest of the requirements were fulfilled by fossil fuels, with coal generation accounting for 59 percent of the total. As a result, CO2 emissions from the power industry set a new high in 2021, rising by 7% to 778 million tons, the highest absolute increase ever.
With the rising oil prices amid Russia’s conflict with Ukraine, there is a real risk of a return to coal, jeopardizing the global 1.5 degree climate goal. Clean energy must now be built on a heroic scale. The smart building in UAE, has made Dubai: a sustainable and smart city to live in. In a movement to build a sustainable future, they are implementing energy efficiency in UAE.
Leaders are only now realizing how quickly they must transition to 100 percent clean electricity in order to keep global climate warming to 1.5 degrees Celsius above pre-industrial levels, as targeted by the International Energy Agency (IEA). Solar and wind energy must maintain compound annual growth rates of 20 percent through 2030.
This is now happening as: solar and wind are the minimum cost resources of electricity at a normal basis, with growing global experience integrating them into high-level grids. With 50 countries now generating more than 10% of their electricity from these easy-to-deploy resources, and three countries generating more than 40%, it is clear that these technologies are working.
Governments in the United States, Germany, the United Kingdom, and Canada are so confident in clean energy that they intend to convert their grid to 100 percent clean energy within the next decade and a half. However, with coal prices still rising and electricity demand rising, all governments with carbon-intensive grids must now act with the same boldness and ambition.
