This is not the first time Mark Jacobson and Mark Delucchi have done this.
But this time, they clarified how 139 countries were able to collect energy from wind, water and solar technologies in 2050 to meet all the needs of home, business, industry, transportation and agriculture.
Recently, they published maps of renewable energy sources in 139 countries, similar to the renewable energy projects they planned to implement in 50 US states or even around the world a few years ago.
This blueprint lists the specific quantities of wind turbines, solar power plants, dams, and other facilities that each country needs to achieve 100% renewable energy. This aspect is seen as a transformation, and on the other hand, it has been criticized as being impractical or even crazy.
But what is certain is that Jacobson hopes that through the 21st Conference of the Parties to the United Nations Framework Convention on Climate Change (COP21) in Paris, France, leaders can understand that international agreements to reduce carbon dioxide emissions are valuable. But if the energy systems of each country can complete the overall transformation to renewable energy, then they don’t even need to pay attention to the emission reduction regulations because the transformation into a renewable energy country means ending the history of the burning of coal, natural gas and oil, which produce a lot of carbon dioxide.
“People just didn’t realize what was feasible,” Jacobson said. As a professor of civil and environmental engineering at Stanford University, he is also the director of the School’s Atmospheric and Energy Program.
Jacobson insists that 139 countries’ renewable energy plans will be implemented – not only because they provide a low-emissions path, but also because in the long run, over a 35-year period, these plans will It will create 24 million jobs in construction and 26.5 million jobs, offsetting 28.4 million jobs lost due to the elimination of the fossil fuel industry.
In addition, achieving 100% renewable energy will prevent premature deaths of between 3.3 million and 4.6 million people due to air pollution from burning fossil fuels by 2050.
“These numbers will draw people’s attention.” Jacobson said.
Jacobson’s partner, Delucchi, is a technician at the University of California, Davis. In 2009, in a special report published in Scientific American magazine, he and Jacobson first proposed a 100% renewable concept. That article explained how the world gets all the energy it needs from 1.7 billion rooftop solar systems, 40,000 photovoltaic power plants, 3.8 million wind turbines, 900 hydroelectric plants, and 490,000 tidal turbines.
“The whole idea originated from the article by Scientific Americans,” Jacobson said, “Now there are five or six non-profit organizations that use 100% in their names. Wal-Mart, Google, and Starbucks all said they want to achieve 100% renewable energy. Many cities as well. We have the space to guarantee their 100% target for the goals of the US states and 139 countries.”
As the first, California, New York, has passed legislation requiring 20% of energy to come from renewable sources in 2030. Hillary Clinton also agreed to support the United States to achieve the goal of 100% renewable energy by 2050.
By 2050, energy needs in 139 countries will be met through a wide range of wind, water and solar technologies, 19.4% offshore wind farms, 42.2% utility scale PV arrays, 5.6% roof solar panels, 6 % of commercial rooftop solar panels, 7.7% of concentrating solar thermal arrays, 4.8% of hydropower, and 1.47% of geothermal, wave and tidal power plants.
Jacobson, Delucchi and a dozen colleagues from around the world published in a self-published article the details of each country’s 100% renewable energy. Although the plan has not yet been published in magazines, they have this plan, after all, their previous plans have been published.
A huge obstacle to the popularization of renewable energy is that wind and solar lights are intermittent. The wind does not blow all the time, and the sun cannot always shine. This means that large-scale energy storage is a must. Storage adds significant cost and complexity to renewable energy systems, but Jacobson already has a solution.
By using smart combination technology, one technology can be used to supplement the other in different weather conditions during summer and at different times of the day to keep storage at a minimum. He and Delucchi and two other colleagues explained in detail in an article published in the November 23 issue of the Proceedings of the National Academy of Sciences how the United States uses this technology.
The engineering details of all of these articles and plans are breathtaking. The document publishes a detailed technical portfolio for 139 countries and the land and roof area required for each country.
Since 2009, these two scholars, along with many other researchers, have been pushing these numbers over and over again. Jacobson said that the most important thing to do now is to make it public.
“We have talked to hundreds of experts and politicians, and what we need to do now is to communicate it to the general public. I hope they can see these possibilities and need them,” Jacobson said.
This is why Jacobson and other entrepreneurs and entertainers are beginning to promote the road map to the public, entrepreneurs, and policy makers. The Elomusk Foundation, the Leonardo DiCaprio Foundation, etc. have all funded this program.
“We are trying to find a way to bring together business, culture, and science to tell stories,” Jacobson says, “We want to explain the benefits of the program to everyone in the world, and good things will happen.”
