On the subject of "Green Energy" did you see this in the Torygraph

Geo thermal causes earthquakes - so another way of cutting CO2 goes

Personally I don't see wind turbines as much of an eyesore, no more than say... pylons, which also prompted a lot of criticism when they started appearing. There are of course bad places to put a wind turbine and in specific instances there can be cases made against them, but the eyesore argument isn't enough to convince me that they're a bad thing per se.

However it's very questionable that wind power can ever make a significant contribution to our energy needs, the area where they could be most useful in my opinion is at the individual level. Namely that individuals (and I live in a rural community and know a person who's already done this) can generate a proportion of their own electricity using wind turbines on their own land. That's when the economics start to make sense, but the government building masses and masses of wind turbines to power the country is a bit of a fantasy as far as I'm concerned.

You are right. You can't build them everywhere.
I was just trying to show that there are other ways of providing electricity round the clock.

The Tummel hydro scheme in Scotland produces as much as about 1,000 decent sized wind turbines.
Not a lot of people know that.......

I certainly prefer hydro electricity to wind turbines.

There was something on Teletext earlier today about a new wave power system opening in the Shetland Islands which will provide electricity for 1000 homes.

Again, I prefer wave power to wind power. Wind turbines are ugly, unlike wave or hydro.

Pylons don't seem to kill rare birds, but the blades of wind turbines do.

There is a big fuss, as you will know Blank Frackis, in Scotland at the moment about wind turbines causing the building of pylons across 200 miles of scenic countryside (to carry electricity cables from wind turbines to the populous Glasgow/Edinburgh area.

It has to be said that electricity pylons don't appear to reduce the value of houses in the way that wind turbines do. I was reading something a few hours ago about how house prices will drop dramatically in villages where new wind turbines might be built thus spoiling the view of Dartmoor in Devon.

Research also shows that wind turbines emit sound which travels through the ground causing people to have sleep problems at night. A doctor in north Wales is among others who have looked into this after complaints from patients living near an ugly wind turbine 'farm'.

Britannist, do you have a link for that research?

Quoting what I said earlier, eye of the beholder.
As it happens, I did the electrical calcs for one of the early wave power schemes that is now up and running off Islay. Gratifying that my work has been part of a project translated into a practical result.
I should promote it as it is potential business. But I am pragmatic enough to realise that it isn't an answer to our energy shortfall.
