Boxing Day viewing



An Inconvenient Truth is released on DVD on Boxing Day. Obviously it won't arrive on the 26th, but it's worth ordering as a late present.

There's a book to go with the film, also available in a young adult version due in April.

It's A Green Christmas In This Town

(Cross posted from Spinneyhead)

Manchester City Council have some statistics on waste this Christmas, plus some ideas on how to cut it down (mostly by carefully choosing what to buy, which might be a little late for most of you) and some guidance on what can be recycled.

If you live in Manchester, the link to the recycling centres around Manchester and what each one accepts is also useful.

The home turbines aren't turning

Whilst large scale wind farms are quite efficient, especially the less controversial new breed of offshore ones, home turbines can produce little or no power because of wind turbulence. Perhaps it's just the traditional windmills that have this problem and the next generation of home based wind power will involve Savonius or other vertical designs better suited to catching the breeze from constantly changing directions.

And now for some really bad news

Based on current measurements, the Arctic summer ice cap could be gone by 2060. However, if the expected feedback- less light reflected by ice, more absorbed by exposed sea- happens, it will be even earlier than that.

Recent studies suggest that even a minor local nuclear exchange could cause a far worse nuclear winter than previously expected. But don't tell Bush that, or he might suggest it as a solution to global warming.

Sticking plaster solutions- towing airliners

I suppose every little helps, but you can't help thinking that Virgin air's plan to tow airliners out to the runway, rather than having them get there under their own power, is a mostly symbolic piece of environmentalism.

Fines and bath reduction- council level green action

Two proposals from local councils to battle energy consumption and waste-

Barnet has drawn up guidelines for planning, including a suggestion to leave baths out of new builds.

Towards zero carbon new builds

When I wrote the piece about net energy producing social housing last night I hadn't seen all of the proposals in Gordon Brown's pre-Budget speech. Amongst the plans is the aim to have all new build homes zero net carbon producers within a decade. The carrot for this is a rebate on stamp duty for all new homes deemed to be zero carbon, to start next year.

There's no definition of what constitutes a zero carbon home, we'll have to wait for the Budget proper for that, and builders' groups are already weighing in with complains about the rebate not covering the extra cost and house prices going up. Of course, house prices are rising regardless, and I'm sure there's a case for larger mortgages on such properties because the savings on bills will make the buyers better off on a payment to payment basis.

Department of Free Ideas: Net energy producing social housing

The Department of Free Ideas is something I've rolled out a couple of times at Spinneyhead. It's basically irregular posts where I outline ideas I've had that I just don't have the time, money or expertise to follow up. They're just ideas, not costed and often without links to supporting material, but I believe they merit further investigation, which is why I want to set them free. If anyone likes them and can act upon them, then they're more than welcome to. Credit or royalties would be cool, if you're inclined.

We don't have enough houses in Britain. Particularly, we don't have enough affordable houses and council house building has ground to a halt. On top of that, we really should be doing more to cut energy consumption. So why don't we solve these problems by building council houses that are so efficient that with the addition of micro-generation they produce more electricity than they consume?

These houses couldn't be individual show pieces dropped amongst ordinary box homes, for the scheme to work properly whole streets or closes would have to be built. Economies of scale menat that technology that would be exorbitant on a single house could be incorporated relatively cheaply. Heat pumps could warm whole closes and the buildings could be arranged to catch and convert the most sunlight.

Tenants would have to sign up to certain community responsibilities, the sort of "socialist" idea that drives some reactionaries mad, but in return they'd get to live comfortably without worrying about ever rising energy costs.

Poorer families can't afford energy saving devices, partly because they're struggling with the cost of the energy they're wasting through older equipment and poorly insulated houses. Even if no council will take up the challenge of building such green homes for them they should at least be subsidised to make the savings themselves.

SUV sales fall

The message may be getting through. Sales of larger 4x4s dropped 5.5% in the first 10 months of this year, and by 15.2% in November. The Society of Motor Manufacturers and Traders says this is because of the phasing out of two popular models and sales will pick up again, but I have more faith in people's common sense.

Carbon Trading for industry

Gordon Brown looks set to propose carbon trading for business in his pre budget speech today, along with increased fuel duty for drivers and fliers.
