The embodiment of everything I have been banging on about since the 1960s

Hydroelectric schemes are not unusual in Scotland, where lochs and reservoirs currently provide enough water to power around half the nation's homes, according to the Scottish Environment Protection Agency.

Knoydart, though, is different - so remote that it is not connected to the National Grid, meaning prices here are not dictated by the wholesale cost of more expensive forms of energy such as gas.

 

Just look how low this dam is.

What do you mean?

Currently, around 5000GWh (Gigawatt hours) of electricity from hydropower are produced every year; that’s enough to power roughly half of Scotland’s homes.

...

Are you pointing to how they're able to do so much with a small dam?

Quote

However, if not constructed or maintained in accordance with best practice, hydropower can seriously impact on river ecology and fish stocks. In the worst case, rivers could be dried-up completely for hundreds of metres downstream. So, striking the right balance between protecting the water environment and renewable energy generation is vital.

Or are you saying the water flow past the dam is low? Resevoir looks topped off.

 

Reading a while it occured to me to construct an inlet off from the ocean, allowing water to move inland and downhill to run a turbine and have it go to groundwater or form a small delta. Probably engineering contingencies I'm not taking into account. Please elaborate on what it is you're trying to continue to bang on about.

Surely the relevant question is how high this lake or tarn is above the generating station, i.e. the head available for power generation. In the Highlands, one of the things that is free is height.

How much habitat  was flooded to make it?

[Sensei]

129 L per second flow * g * height = max power you can get from it. This does not look impressive. In rural uninhabited wasteland - acceptable.

However, they would get more from solar panels on the roof.
