I'm not getting it! What is the water used for? It looks as if they are talking about hydropower to generate electricity, but the energy generated in proportional not only to the amount of water, but to the height of the tamed riverfall as well. How much does this half liter of water fall, to generate the power?

When you start making back-of-envelope calculations, you probably at first think that you are getting the magnitudes wrong. Hydropower requires huge amounts of water!

Here in Norway, we have reservoirs typically around 1000 m above sea level. Assume that the generator is located at the sea shore so the full 1000 m fall is used. A typical Norwegian family consumes 20 000 kWh of electric power a year (yes, we use it for everything, from fueling cars to heating water to heating and lighting up homes). To produce that power, around 8 million liters - 8000 cubic meters - of water must be drained from that high mountain reservoir a year.

If the electricity I buy is produced from a dam in the river, the dam being only 10 m high (with the generator at its foot), it will take 800 million liters of water to serve my home alone. Another 800 million liters for my neighbor to the left, and the same for the one to the right, the one across the road and every single family home in the nation.

That is quite a lot. More than 2 million liters a day, from the 10 m riverfall power station. "Only" 20,000 liters a day from the 1000 m high reservoir.

Or for those of you who prefer modern, silly units: The riverfall power station would have to let through almost an olympic swimming pool of water every day, year around, to satisfy my needs alone. I guess you wouldn't notice if it was 500 ml more or less.
