The China Announced The Start Of Construction Of The World’s Largest Hydroelectric Power Plant, Located In The Far East Of The Tibetan Plateau, Near The Border With Bhutan And Nepal. The Megaproject, Expected To Cost R$ 900 billion, Integrates The Country’s Five-Year Plan And Aims To Boost The Economy And Expand The Supply Of Electricity.

The Plant Will Be Built Along The Yarlung Tsangpo River, Which Flows 2,900 Kilometers From The Himalayas And Forms The World’s Deepest Terrestrial Canyon. There Will Be Five Cascading Plants, With A Joint Capacity To Produce 300 Billion kWh Per Year, An Amount Equivalent To The Annual Energy Consumption Of The United Kingdom.

The Project Was Initially Presented In 2020 And Received Final Approval In 2024. The Prime Minister Li Qiang Described The Project As “The Project Of The Century” During The Launch Ceremony, Highlighting That The Hydroelectric Power Plant Is Expected To Have A Direct Impact On The Growth Of China’s Gross Domestic Product During Its Decade Of Construction.

Energy Impact And Comparison With Three Gorges

With A Capacity Three Times Greater Than The Three Gorges Plant, Currently The Largest In The World, The Hydroelectric Plant Is Expected To Supply Tibet And Several Chinese Provinces. Part Of The Energy Will Also Be Directed To Export Networks, Strengthening China’s Role As A Global Supplier Of Clean Energy.

The 5 Largest Hydroelectric Plants In The World And Their Impacts

1. Three Gorges (China)
Located On The Yangtze River, Hubei Province, It Is The Largest Hydroelectric Plant In Operation, With 22.5 GW Of Installed Capacity.

Environmental And Geopolitical Concerns

Despite The Economic Potential, The Project Raises Concerns Among Neighboring Countries. In India And Bangladesh, The Yarlung Tsangpo Becomes The Brahmaputra River, A Vital Source Of Water Supply And Irrigation For Millions Of People. Local Governments Fear That The China May Manipulate The Flow Of The River In Times Of Political Tension, Causing Floods Or Artificial Droughts.

Environmental NGOs Also Warn Of Ecological Impacts, Including Potential Changes To The Region’s Ecosystem And Risks To Local Species. In Response, Beijing Has Assured That The Dam Will Not Cause Harm To Areas Downstream And That It Will Maintain Communication With Affected Countries.

The Information Was Released By braziljournal And International Agencies, Based On Official Announcements From The Chinese Government And Economic Impact Estimates Provided By Citi.

The 5 Largest Hydroelectric Plants In The World And Their Impacts

Environmental And Geopolitical Concerns

Mother and daughter build a 70 m² house with more than 8,000 discarded glass bottles and impress with their creativity; known as the Casa de Sal, the property is located on Itamaracá Island, in Pernambuco.

The river that “dies” in the desert never reaches the sea and yet gives life to one of Africa’s largest natural refuges in a truly impressive way.

He transformed an abandoned plastic water tank into an underground house in the “hobbit hole” style, using only repurposed pallet wood, without heavy machinery or expensive labor.

Libya built over 4,000 kilometers of underground pipelines to bring water from the Sahara to coastal cities in a project that the government itself called the Eighth Wonder of the World.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

Toyota launches “family hybrid van” with 7 or 8 seats, 1.8 hybrid engine, fuel consumption of up to 23.8 km/l, and a price equivalent to about R$ 104,000 without taxes, below the Tiggo 8 Pro Plug-in Hybrid sold in Brazil: meet the Noah Hybrid 2026 in Japan.

Desert sand, previously discarded for being too smooth for concrete, becomes an ecological brick in the United Arab Emirates, dispensing with Portland cement, curing at room temperature, and attempting to transform dunes useless for construction into raw material for a new arid engineering.

Google employee lived in a 12 m² truck in the company parking lot, used the campus facilities, and exposed the burden of rent in Silicon Valley.

To escape one of the most dangerous seas in Europe, Norway is advancing with a giant tunnel that will allow ships to pass through a mountain, avoiding storms, unpredictable waves, and a route that has frightened sailors for generations.

INSS issues alert to retirees: decisive deadline ends this week and millions of beneficiaries may lose access to amounts that already total R$ 3.2 billion; measure involves deductions made between 2020 and 2025

Forget the dollar: Brazil, China, Russia, and India accelerate testing of the BRICS system to challenge SWIFT, reduce US influence, and expand transactions in national currencies, which already account for 67% of the bloc’s trade.

Forget the slow sweeper: China creates a vacuum truck that cleans highways at up to 80 km/h, sucking up stones, dust, and metals from the asphalt and promises to reduce blockages without stopping traffic.

Brazilian scientists are simultaneously advancing two research projects on clean hydrogen and driving solutions that could transform the energy matrix, enhance industrial competitiveness, and accelerate large-scale emission reduction targets.

Advancement in renewable energy: A R$ 150 million project launched by Petrobras and Finep aims to create state-of-the-art electrolyzers for green hydrogen, strengthening national research and preparing Brazil to compete in a billion-dollar energy market.

Illiterate or semi-literate grandmothers were trained to repair solar systems, open rural workshops, and light up homes that still depended on kerosene.

The world has bet on green hydrogen as the fuel of the future, but now faces the side effect: producing 1 kilogram requires about 9 liters of ultrapure water, and the largest projects on the planet are precisely in the driest regions of the Earth, where water is already scarce for people.

Africa has about 500,000 cell towers and most still burn diesel to operate, while companies rush to cover antennas with solar energy and avoid signal blackouts.
