We're sorry, but this discussion has just been closed to further replies.
Shall we build a new nuclear power plant in Greenock then?
Or just switch off the lights? For good.
I live in Perth, so rather far from the area concerned. However, we do see a small "windfarm" due north of us, on the mid-distance hills near Blairgowrie.
I remain unconvinced by the arguments in favour of this form of electricity, but if "they" are determined to promote and develop it, I say - go off-shore and out-of-sight please!
Ignorance can be dangerous, a little knowledge more so (I fall in to the latter category). There are no easy answers in this debate; change is required in either energy consumption or energy production and people don't like change. It's easier to put up another windfarm than to convince a few thousand people to switch off stand-by, or turn the thermostat down a degree or two.
It may be that we currently export power but with closure of our nuclear power stations and some of the coal ones in the near future, this may not last.
There are a lot of arguments for and against wind energy. It's been 3 or 4 years since I last looked at the figures comparing wind and nuclear energy in terms of CO2 emissions, but the figures then were fairly similar BUT the nuclear figures did not include decommisioning and long term storage of waste products - there are still no widely accepted solutions to this problem! The decommissioning costs are astronomical for nuclear and will be met by the tax payer over the next few decades, while wind farm developers are normally required to provide a bond to cover decommissioning at the end of their 25 year life.
Other renewables all have drawbacks:
Hydro - we already have as much large hydro as we would want - the environmental consequences of flooding large areas are unpalatable. This leaves small scale "run of the river" schemes which could benefit local communities but wouldn't scratch the demand of big towns and cities.
Tidal Current - limited development to date and the infrastructure isn't in place to take the power from the best sites to population centres
Tidal Barrage - there is talk of a barrage in the Severn that would generate 5% of UK electricity demand - at a cost of billions and untold environmental damage. I am not aware if any suitable sites in Scotland for this type of development.
Wave Energy - The Pelamis sea snake - Scottish development - is a promising development but again the infrastructure is lacking.
Biofuels - These often use more energy to produce and transport than they could generate.
Solar - Oh if only we had some more sun!!!
And as for the Hydrogen Economy - Dan is spot on - it won't work unless we can produce the hydrogen from renewable energy. With wind turbines, we could generate hydrogen when there is a surplus of wind and use the hydrogen to generate electricity when there is shortage, thus reducing the need for back up generation. Unfortunately this technology is still a few years from commercial implementation.
From my analysis, wind looks like the least bad option for the short to medium term, i.e. until something better comes along. In 20-30 years, when the current generation of windfarms reach the end of their license period, a much greater portion of our housing stock will consist of low energy homes and there may be less need for a new generation of wind farms. Wind can only ever be part of the mix but it is still a step in the right direction. I think we should try to place them in a sensitive manner and should ensure that the visual amenity of national parks are protected to a certain degree, and possibly a bit less for regional parks. I think it is more important to have them near centres of electricity consumption rather than in remote highland locations - that way we avoid the need for the Beauly-Denny Interconnector.
Braes of Doune Windfarm (visible from the A9 to the north of Stirling) is a poor example of what wind farms should be. The turbines can be placed to minimise visual intrusion to some extent. Windfarms can actually take large steps to improve natural habitats and improve access to the countryside. A visitor centre is being built near Eaglesham for the Whitelee Wind farm and this will give access to the moors for walking and cycling. On other windfarms, habitats are being developed for rare and endangered species such as merlin and red squirrels. There is more to our landscape and environment than broad untainted vistas, if ever there was such a thing. Most of Scotland's landscape has been shaped by man over the centuries and it will continue to be moulded to our needs.
