    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.

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 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.

    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

    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.

This will melt the ice caps and drown us all.
