Windpower advocates lying with statistics

Windpower Roundup reports.

Roughly 176GW of new renewable energy capacity was added last year, accounting for 72% of global power growth

Wind (58.8GW) and solar (97.7GW) accounted for about 90% of the new renewable energy capacity added in 2019, according to Irena’s ‘Renewable Capacity Statistics 2020’ report.

So the wind and sun add 176 GW of capacity, with the extra 10% of RE presumably hydro and odds and ends like biomass. The non-RE 28% of global power growth amounts to some 64GW.

That looks like a great advance for RE until you adjust the numbers to take account of the  capacity factor  – the amount of  the plated/installed capacity that you expect to get over year or so that is near 30% for wind and 20% for solar.  The delivery comes down to   20GW each from the wind and the sun for a total of 40GW.   And don’t mention the choke point!

In contrast to the RE numbers, the delivery from nuclear and hydrocarbon sources can probably approach 100% although the pricing system and the mandates for RE keep the delivery from coal well below capacity in most parts of the western world at present. (Australian black coal has gone as low as 8.1GW and as high as 16.1 GW and it is mostly between 9.5 and 12.5).  If you reduce the 64 to 90% you get 57GW that is well ahead of the 40 from the sun and wind. 

Despite the expansion of renewable energy outpacing (sic) fossil fuels, Irena director-general Francesco La Camera said, “more is required to put global energy on a path with sustainable development and climate mitigation”.

    Quoting capacity (power) rather than output (energy) seems to be stock in trade for renewables advocates.

    First they came to destroy the tried and proven electricity generation and supply system but that didn’t work fast enough for ‘the experts’ so they gave us a pandemic.

    How much new RE was replacing old RE?
    How much baseload was replacing old baseload?
    How much was peaker gas to facilitate RE?
    So much untold.

    OK, good (!) sir, how much mitigation has taken place because of this investment, and how much more could we expect if your call for greater investment is heeded?

    What is even more insane is that wind farms lose half of their capacity after 10 years and are esentially unable to produce power after 15 years according to a study in the UK.

    So much for the 30 year effective life and the associated lifecycle analysis of carbon reduction.
