    Default Renewable energy : why bother?

    Climate change: Electrical industry's 'dirty secret' boosts warming - BBC News

    It's the most powerful greenhouse gas known to humanity, and emissions have risen rapidly in recent years

    Where once large coal-fired power stations brought energy to millions, the drive to combat climate change means they are now being replaced by mixed sources of power including wind, solar and gas.

    This has resulted in many more connections to the electricity grid, and a rise in the number of electrical switches and circuit breakers that are needed to prevent serious accidents.

    Collectively, these safety devices are called switchgear. The vast majority use SF6 gas to quench arcs and stop short circuits.

    ------------------------------

    Lets just start burning coal again. At least the UK has plenty of it.

    If only they could harness the power of the tumbleweed.
    Maybe tomorrow, I'll want to settle down. Until tomorrow, I'll just keep moving on.

    I don't see why there's a need to quench arcs when opening circuits at substations. Let the arcs be free!

    Was that supposed to be a link to demonstrate your point?

    EDIT: link didn't work on the Android app, works fine in the browser :

    I do have to wonder about random wind turbines dotted across the countryside.

    Just seems like a way for farmers / renewable energy cos to cream money off the govt via subsidies.

    Random?

    One tedious morning I counted a mere 75 wind turbines clearly visible from Ye Newe Sloughe of Desponde.

    Instead of coal tips we now have wind turbines.

    At least the coal mines provided jobs.

    The wind turbines, not so much, being imported.
    When the fun stops, STOP.

    They're pretty random over this side of the Bristol Channel but looking across to the other side it looks like you boys have definitely taken one for the team on that score.

    Those giant propellers in the Bristol Channel area are there to pull Airstrip One away from EUrasia.
