Why are they making videos? There using up energy! The world will end because of their silly video! NOOOOOOOO!!!!!!!
They've still got to produce the power even if no-one uses it, its not like they can save up the electricity they produce and you didnt use. Once every one turns their lights on there will be a massive demand and they'll have to prepare fot it else you'll moan that your lights didnt come on and you didnt have any electric.
Like the add breaks in soaps, they wind the generators up to prepare for all the kettles going on, its also why street lights come on in sections not all at once.
People have been banging on about climate change for years and wasted billions on it, i look at it like this, we've come from an ice age, its been getting warmer for longer than we can remember, it'll get colder eventually and then the human race (it we haven't killed each other by then) will spend billions trying to stop global cooling and save endangered species such as the pidgeon and seagull, we'll blame past generations for trying to cool the planet as we now live under 10ft of snow for 4 months a year. And Britain still wont be prepaired as we'll be spending billions in the EU and trying to save the mongolian goat.
Rant over.
