What excellent news

Portugal kept its lights on with renewable energy alone for four consecutive days last week in a clean energy milestone revealed by data analysis of national energy network figures.

Electricity consumption in the country was fully covered by solar, wind and hydro power in an extraordinary 107-hour run that lasted from 6.45am on Saturday 7 May until 5.45pm the following Wednesday, the analysis says.

Ain’t that fabulous? Excellent, so, how’d they do it?

Hydro power mainly. 50% of “renewables” is hydro. Some 5 GW capacity apparently. And another 1.5 GW of pumped storage.

Hey, fine by me, I cycle over one of their damns often enough.

So, now we know how to do it which valleys are we going to go and flood?

  1. How did they do it?

    By using fake figures in the article, of course. This is Goons from the Guardian territory. Whether dishonest or stupid – I can’t tell.

    Let’s leave aside the dishonest comparison between energy to “run Portugal” and the suset of that which is “electricity”.

    The 107 hours claim may be true.

    This, though, is a lie:

    “As recently as 2013, Portugal generated half its electricity from combustible fuels, with 27% coming from nuclear, 13% from hydro, 7.5% from wind and 3% from solar, according to Eurostat figures.”

    Follow the link and the figures relate to the EU-28 not to Portugal.

    Follow the link to the Portuguese renewable association, and look at the 1999-2015 graph, and you see that renewable production – far from “flipping” – actually fell between 2013 and 2015, having peaked in 2012.

    Where does the Guardian get boneheads such as their “Europe Environment Correspondent” Arthur Neslen?

    Presumably the equivalent of our energy from France/Holland/Norway.

    I guess it is nuclear from France or from North Africa.

  3. “So, now we know how to do it which valleys are we going to go and flood?”

    Wales has lots of valleys. Start there. The ones surplus to the hydro electric industry can be used for boating or fishing.

  4. Hydro power is not CO2 neutral (for anyone who might care about such things), nor is it really ‘renewable’. Building a dam requires a lot of reinforced concrete, which is one of the most energy intensive and CO2 emitting of human activities. And all the vegetation that’s covered by the new lake will decompose and emit methane. And all this has a finite lifespan before it silts up or otherwise needs renewing.

    The only really ‘renewable’ form of hydro is to take an existing waterfall and channel it through pipes to some turbines at the bottom. The Swiss do this a fair bit and it’s at Niagara too, but the scope in the UK is fairly limited.

  5. ‘extraordinary’

    So it was a freak event, signifying nothing.

    Meanwhile, the fixed cost of the rest of generating capacity continues to accrue.

  6. And in the 108th hour the lights went out… or they would have if left to ‘unreliables’.

    Meanwhile en France, explan this. France gets over 90% of its electricity from non-fossil fuels (80% nuke, about 10%+ from hydro and geothermic) so why Oh why are they blotting the beautiful landscape with windmills and subsidising wind and solar?

    As we know it is about politics and World government… how better to control 7 billion people than control the energy supply… and has nothing to do with science.

    The science is being uncooperative and showing no evidence of a causal link between fossil fuel CO2 emissions and mean global temperature anomaly, in fact thebopposite, and meterologcal centres report no change in trend in climate conditions outside natural variability.

  7. So Much For Subtlety

    George Monbiot actually earns some credit from me because he is willing to consider this seriously. In, I think, Heat, he argues that we will have to flood pretty much every valley in Scotland.

    This is, needless to say, batsh!t crazy but it is the logical result of what he believes and he does not shy from it.

  8. What happened when the sun went down? Was there only a small component of solar or was it used to store energy? Or was the period averaged to take out overproduction at one time and under production at another?

  9. So Much For Subtlety

    Paul Carlton – “What happened when the sun went down?”

    I believe the official Green line is everyone turns back into pumpkins.

    Hence Monbiot’s desire to flood every valley in Scotland. Pumped storage. It is insane. The environmental damage would be vastly worse than for nuclear power.
