Reply to: Climate change: the true price of the warmists' folly is becoming clear

Indeed, chucking a turbine on the roof of a housing estate property is silly. (Although jolly useful on liveaboard boats.)

Also, putting solar panels on a house isn't going to provide the power to run the kitchen. (Although useful for powering road signs, remote monitoring equipment, emergency lighting and all sorts of other specialist purposes.)

But solar water heating on a new build or when replacing/installing the central heating pays for itself very quickly. Even bunging some old black-painted radiators on your roof, encased in clear perspex, and plumbing them into your heating system (beyond my ability but then I'm useless) is cheap and worthwhile.

My last flat used to have huge south facing (double-glazed) windows which made a huge difference. So much so that I didn't use the central heating and the balcony used to reach into the mid 20 degrees in winter on a sunny day.

People can choose to use microgeneration if they have deep enough pockets, but a small turbine on the roof isn't going to be as economic as a monster turbine serving a whole community, so I don't see why those should subsidised. Heaven forbid we squander taxpayers money wastefully in the name of climate change. Solar is very expensive in terms of primary (electric) energy, although it's possible there's a case for micro solar thermal, especially if a house is designed to be more greenhouselike.

Because the government is in the pockets of the big building companies. Our building regulations are tulipe relative to other countries when it comes to insulation and energy re-use, let alone generation.

Because if new builds had solar water heating (and solar powered pumping for it) the energy saved would be immense. Any microgeneration would be a useful bonus.

Given that the vast majority of the cost of a new build is the tiny patch of flood plain it is sat upon, it is appalling that an extra few grand on each one is not legally required to be spent on making them very energy efficient. Especially since the building companies have already held much of that land for decades.

If they use scuba to go and get it, the number of pikeys is going to decline. Rapidly.

I think we'll see a run on snor*kels though

[Moscow Mule]

So sales of scuba outfits to pikeys is going to flourish

I bet some of the stuff is nicked before it ever sees the water

I wish I could get my hands on all the offcuts though

Why is the government no supporting small scale solar power / water heating systems more? Even in the Uk they are effective on overcast days.

Why should the government support microgeneration when it's more cost effective to produce energy centrally?

Wind turbines are not the only new power sources currently under consideration / construction.

There are currently about 3 gas stations under construction / comissioning.

I think 2 new coal stations are being seriously considered (it was about 5 a couple of years ago).

We are likely to build 4 new nuclear stations (the planning awards - locations - have been granted, detailed design is now ongoing).

This is a good mixture of power generation with current technology.

But we are due to decomission approx 7-8 coal stations, 3-4 oil stations after 2015. We are not building enough now to replace this, but the recession has helped demand.

What material do they use for the underwater power transmission cables? Copper, aluminium, a compound?

Is that the bootlace principle?

As in, you can't pull yourself up by your own bootlaces? Yep.

[Doggy Styles]

Coriolis force. Since angular momentum is conserved, I don't think there will be net change to the rotation of the Earth.

[TimberWolf]

b) I cannot remember the correct terminology but the circular force of the drag caused by the wind turbines is converted into a force at 90 degrees, i.e north/south and since prevailing winds all go one way, the wind turbines will start to force the earth to spin top to bottom rather than side to side. This will melt the ice caps and drown us all.
