The economics of wind power are well dodgy, as are their green credentials.

I'm all for nuclear, it is well managed in this country. The French have the right idea, went for nuclear in a big way and don't need to rely so much on fossil fuels. We need to tell the green lobby to get lost and go for it big style as well - as we should have done in the 80's and 90's.

There should be small farms dotted arund the country

What about people having small wind turbines on their roof-tops? It might only generate enough electricity to say power the lights, but thats not a bad thing.

I getting a lot better though, someone has realised a car recently that had a proper range, short charge times and reasonable performance, i reckon 15 years to proper commercially available cars.

I can only see nuclear as the way to go, we cant be reliant on the Russians/Arabs for energy. As far as I know we have no real way on generating serious amounts of renewables and the only other option is coal which is a little smoky. I wonder if green peace has come up with a solution from where all this magic electricity will come from?

The french seem to have had great success with nuclear, I belive they have mostly identical stations so they are easy to maintian.

Well I would agree with that, but the economics do not stack up without a massive subsidy in the form of the Climate Change Levy which is piled on our electric bills and used to subsidise wind energy (amongst others). Without this, it is not economically viable. So to get a return, companies build MASSIVE wind farms to gather economies of scale. Then to increase the efficiency they cut down any trees in the vicinity that interrupt the laminar wind flow. (Hardly green is it?) Around here, if all the applications for wind farms go ahead there will be about 5000 acres of forest felled to improve the wind how is that green FFS? And the trees will be left to rot, as the timber market is very depressed at the moment (cheap Russian imported timber) . This will release all the CO2 trapped in the wood back into the environment....... It's all ******** brought on by a target obsessed government. If they took a holistic approach to this then wind, hydro and tidal power could help with the country's needs. Grrrr desecration of the countryside for no gain. And don't get me started on the sites chosen for these monstrosities.......

Micro generation is a good prospect, especially micro hydro. The problem with all the micro generation schemes is cost and reliability. No wind = no power. No water in the summer = no power. You still need the 'spinning reserve' of coal / oil / gas / nuclear to make up the shortfall when nature is not playing ball.

I didnt think about it like this (concentrating on other stuff...thats my excuse anyway). I do however understand that theres gotta be energy spent to make energy saved...

...how much greenhouse gas will be emmited to make all this "green" stuff?

I think there should be something done about landfills; they release alot of methane (more potent greenhouse gas than CO2) and other sources of methane (cant stop the natural sources, but could do something with man-mad sources?)

true, they are always getting better, but the only things that will drive people to want electric cars are either superior performance / range / price compared to petrol rivals, or a massive increase in the price of fuel, if we're lucky the two will coincide over the next few decades and the transition will be smooth

no, environmental campaigners don't offer realistic solutions, they moan about problems and demand unrealistic solutions:rolleyes:

Well I was not counting the damage to the environment building the things, the new roads needed to carry the enormous sections of towers, the invested energy in all the concrete required, the new power lines, etc as this is an infrastructure cost that has to be paid for in any new power source.

BUT WHY ARE WE LOCATING THEM IN NORTH / MID WALES, ISLE OF SKYE, NORTHERN SCOTLAND ETC WHEN THE FOLKS THAT WANT THE POWER ARE IN THE SE ENGLAND? All the infrastructure required for the power transmission needs to be built and that is an environmental overhead. These massive wind farms should be located on the essex coast... plenty of laminar wind, close the population that needs it, flat, easy access to the firms that build the turbines (German and Dutch) by sea..... but hang on, Essex has the highest density of millionaires in the UK and lots of politicians and industry leaders live there........... cynical? me?

Our windswept island has more than enough wind, wave and tidal power potential to meet all of our energy needs many times over. Between them, wind, wave and tidal power could deliver more than twice as much electricity than the proposed new fleet of nuclear reactors in the same timeframe - and the renewables would come online more quickly, require no fuel and won’t have the danger or cost of the nuclear waste.

Greenpeace seems to think that wind, wave and tital are the way forward. Nice idea but personaly I'm not convinced. Its going to be a lot of windmills about.

What happens when the wind don't blow? No wind for the turbines and little or no wave action.... Complete rubbish.

They'll say "because that is the best area for these windfarms to operate efficiently"

I'll say "because they dont want them in their back yard"

Its like politicians, wanting a war, but not sending their own children to fight
