I wouldn't exactly call hydro clean.
The new dam in Tanzania, officially named the Julius Nyerere Hydropower Project, used approximately 2.6 million cubic meters of concrete for the main dam structure and its associated facilities. The amount of steel used is around 5.7000 tons of steel bars.
Here are the specific quantities for the project:
Concrete: The main dam utilized approximately 1.4 million m³ of Roller Compacted Concrete (RCC). The overall project, including subsidiary dams and other structures, involved a total of around 2.6 million m³ of concrete pouring.
Steel: The project utilized approximately 5.700 tons of steel bars. Note that this tonnage seems low for the scale of concrete used compared to other mega-projects (e.g., the Three Gorges Dam used 463,000 tonnes of steel) and may refer to a specific component or a misstated unit in the source document. Oh and 5 million m3 of earth to fill the saddle dams. I'll let somebody work out the amount of CO2 that that construction produced. It is said it would be a more to sized over its 80 to 100 year lifetime but according to activists we will all be gone by 2030 or was that 2020 or 2010 or 2000 😀
