Please note nothing about being wood chip free.
What hypocrisy.

SOOO Britain got to 28% solar and wind . That is a LOOONG way from 75%.Quote:
The bright and breezy weather helped wind and solar power make up about 28% of Britain’s electricity last month, narrowly behind gas-fired power generation, which made up 30% of the energy mix.
And since when do the greenies consider gas as renewable and clean?
Storing Excess energy via our Pumped Hydro or battery (not my idea of cost effective) or Hydrogen will solve that one Phillip.Quote:

What about flywheels on superconducting bearings.
In the mid 2000s there was quite a bit of discussion about building massive flywheels in abandoned mining pits eg Hunter Valley. Flywheels were used years ago in Swiss buses. Even before that when I worked at DCA as a teenager the no break Dorman Gen sets used in airports had a massive flywheel to cover the period from power failure to diesel start up, and that was over 50 years ago.
Flywheels are used on a smaller scale at Coral Bay to stabilise the power in the transition between wind and diesel generator.
Unfortunately I think I will be dead before these things come to fruition. Even the Snowy 2 will probably not be finished for many years.

Britain goes two months without coal power.
Britain goes coal free as renewables edge out fossil fuels - BBC News
Oh look carbon shedding... 7 million tonnes of wood pellets, all processed overseas and then shipped in big cargo holds fuelled by bunker oil.
The UK pulled a similar stunt with manufacturing a while back. Moves the biggest polluting industry off shore and imported the final product.
That's 5%. What about the other 95%? And they're going to close down the three remaining coal plants. Redundant.Quote:

Must be great to think only in utopian terms without the burden of current physical and economic realities to get in the way.
I wonder how they will go in the middle of winter?
I think we can guess the answer to that.
Several years ago I read about what happens in power station control rooms in the UK when there is a sudden demand. The scenario was when there was a major football match, such as a final being broadcast. As soon as the match finished the millions watching it on TV made a dash for the kitchen and turned on their electric kettles to make a cup of tea. Oops!Quote:

With a conventional thermal power station you can keep units running on low load ready to take up the surge, but unless you have a direct line to the almighty, that is going to be a problem with a wind farm.
I posted previously about the lack of "inertia" in a grid relying on both wind and solar, and it is still a problem.
