Weaknesses Of Wind And Solar: When Science And Reality Clash – Part 2

If you’re in a country spending fortunes on erratic renewables you won’t enjoy these engineering-based conclusions about them.

In Part One we established a Rule of Thumb for electrical engineering which states: All Solar and Wind Power on an Electric Grid Must Be Backed Up With an Equal or Greater Amount of Fossil Fuel Power Running on Standby 100% OF The Time.

There are those who claim that one day these intermittent sources will be backed up by batteries, which is the claim of the solar plant to be built in the Mohave Desert 30 miles NE of Las Vegas. In a future article we will explain with simple arithmetic why this can never happen at any affordable costs based on the laws of physics. For now we want to address the claims that have lead to the distorted interest in solar and wind power.

Daily academia, the press/media, the CO2 industry, and politicians sound the alarms with headlines screeching:

    The Irish grid, on an isolated island, is a small microcosm of those in the EU. Of its nineteen power stations, the oldest and largest is coal fired and to meet EU renewable targets in the period 2012 to 2018, half its output was ‘replaced’ by the output from 1,100 new wind turbines, each costing €4 million to install.

    Electricity generation, in modern Irish gas turbine power plants, emits 40% the CO2 arising from generation with more difficult to combust carbonaceous coal. In 2012, gas generated half of Irish electricity, as it did again in 2018, but this time with a significantly higher gas consumption. When your car comes off the motorway and goes into ‘stop start’ urban driving it burns more fuel, just like power plants forced into such operation, as more and more intermittent wind energy pours on and off the grid.

    The extra gas combusted was well capable of supplying Ireland with 4% of our electricity. Simply switching this coal generation to natural gas and running Irish plants efficiently could have realised over 70% of the emissions savings claimed for renewables. In fact, this is what the USA did in the period 2008 to 2017 and obtained a 27% reduction in CO2 emissions from their power generation sector.

    If instead of spending a trillion Euros on wind turbines and PV solar panels, a budget of €10 million was provided each day to sprinkle around the EU like ‘pixie dust’ for the ‘common good’, the trillion would run out in 274 years. Equally, it would have paid the majority of the EU’s total food and drink bill in 2018 of €1.1 trillion. Instead, we got EU power sector emissions to decrease 28% in the period 2008 to 2018.

    The EU publishes an energy price report every two years. Last year of ‘full data’ is 2016; circa €400 billion bill for energy sources, €212 billion being imported fossil fuels, plus an additional tax squeeze of €280 billion. €76 billion in subsidies for renewable sector equating to €208 million per day or €150 from each citizen. €48 billion paid direct to wind and solar generators on top of market price for 13% of EU’s electricity. Market price plus tax paid to gas and solid fuel generators for 41% of electricity, whose fuel costs were same €48 billion.

    Charles MacKay in his 1841 book ‘Extraordinary Popular Delusions and the Madness of Crowds’ pointed out: “Men, it has been well said, think in herds; it will be seen that they go mad in herds, while they only recover their senses slowly, one by one”.

    Isn’t it just great how the article’s subject segue’s from one artificial calamity into another, well-worn and tired?
    The world is not short of water. Its short on POTABLE and irrigation water. Water is the planet’s most basic renewable resource of which we cannot ever run out of. What we need is better methods of cleaning and distributing water.
    As for the other scarecrows, those have been repeatedly shown to be false.Like every other kind of analysis, its all in how one slices and dices the data, and what crucial information and assumptions are conveniently left out.

    Pat Swords says: ‘spending a trillion Euros on wind turbines and PV solar panels’

    To which we can add something like *every twenty years*. That’s a lot of materials to dispose of too.

  4. Curious George says:

    The original post contains a misleading graph of wind-turbine power vs wind speed. Someone cut that graph at 25 knot wind speed, creating an illusion that above 17 knots the turbine always works at 100%. In fact, it switches down when the wind gust speed exceeds 30 knots.

    “What we need is better methods of cleaning and distributing water.”

    “We,” kemosabe?
