BloombergNEF (BNEF) Shows That Investments Need to Increase to Meet New Demand and Replace Electric Power Infrastructure

BloombergNEF (BNEF) released a report showing that by 2050, the world needs to invest at least US$ 14 trillion in electric power grids to support the evolving energy system. According to research experts, as grids become smaller and closer to demand, new distribution networks become increasingly important.

BNEF experts say that “In 2020, around US$ 235 billion was invested in the electric grid, and that needs to increase to US$ 636 billion by 2050 to support more energy generation capacity, meet new demand, and replace existing infrastructure.”

“The growth of wind and solar in our economic transition scenario causes the average size of power plants worldwide to fall six-fold by 2050 to 158 MW. This results in more plants connecting directly to the grid – accounting for, by mid-century, 63% of annual investment, up from 52% in 2020,” the study states.

China is the largest single-grid market in the world between 2020 and 2050, despite a potential slowdown in demand growth. According to the report, “In the 30-year outlook, one-fifth of global investment or US$ 2.9 trillion occurs in China. Ultra-high voltage transmission systems continue to dominate, enabling the integration of remote, high-quality renewable energies.

Due to the relatively slow uptake of renewable energy use, investment in grids in the United States, currently the second largest market, lags behind Europe. The research concludes by stating that “Annual funding more than doubles and exceeds US$ 100 billion by 2043. The country’s new president, however, could trigger more ambitious investments in the grid based on recent carbon-free electricity goals,” mentioning that the U.S. could see better metrics under the presidency of Joe Biden.

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

Forget petroleum-based asphalt: a Scottish company transforms 684,000 plastic bottles into one kilometer of road that is 60% more resistant and up to 10 times more durable, and the technology has already started replacing traditional asphalt in more than 30 countries.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.

The James Webb telescope spotted a planet 700 light-years from Earth with mornings full of sand clouds and nights with clear skies, the temperature difference between the two hemispheres reaches an impressive 170 degrees.

At 4,400 meters of altitude in the Himalayas, where the air is so thin it makes breathing difficult, India’s state oil company drilled a thousand meters of rock to reach a 240-degree subsoil and set up the country’s first geothermal plant.

Renault 4 electric gets Plein Sud version with a fabric roof that opens 92 cm, starting at €37,290 and featuring 28 driving assistants in a nostalgic bid to drive in the open air without sacrificing interior space.

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

MIT prototype uses AI, camera, and electrical muscle stimulation to help a person draw, play simple notes, and perform technical gestures with their hand.
