Costly & Pathetic ‘Performance’: Thousands of Wind Turbines Being Replaced After 12 Years
23 Apr 2023 Leave a comment
Wind industry shills still make ludicrous claims about turbines running on the smell of an oily rag and lasting for 25 years or more, needing little more than a hug from time to time. They never talk about the operations and maintenance costs which – as reported by one Australian outfit Infigen – runs at around AUD$25 per MWh (which undermines the myth about wind power being generated with zero marginal cost).
Then there’s the incontrovertible fact that industrial wind turbines are lucky to have an economic life of anything beyond a decade.
As it approaches its 10th birthday, a wind turbine has often had its blades, generator, bearings and/or gearbox replaced – see our post here – as well as undergoing routine service and maintenance, the need for which only increases, over time.
As with any industrial machine, operation and time conspire to cause wear and tear of…

That’s the face of our star, the Sun, based on a collection of pictures from NASA’s Solar Observing spacecraft, SOHO.
Right now it’s a very turbulent star as it approaches its Solar Maximum in 2025/2026. This is the 25th Solar Cycle since regular observations and recordings began in 1755, and it was expected to be as weak SC 24.
Wrong.
Sol has been going apeshit recently, with solar flares and CME’s (Coronal Mass Ejections) that have been lighting up the skies with the Northern and Southern lights pushing beyond their usual, visual areas. It seems to have effected the Northern Lights more, with them being seen as far south as the Shenendoah Valley in Virginia, in a replay of scenes from 1862 after the Battle of Fredericksburg:
Befitting scene! Who would die a nobler death, or dream of more glorious burial? Dead for their country’s honor, and lighted…

Global Warming Silliness

I’m a great fan of nature, but our friends on the left seem a bit extreme.
- Self-styled environmentalists assert that you’re racist if you oppose their agenda.
- Some of them don’t believe in bathing.
Or consider the ones who produce/use hand-cranked vibrators to reduce their carbon footprint.- There are also self-proclaimed environmentalist who claim that climate change causes AIDS.
- Or that it causes terrorism.
- And some of them put together a ranking implying that Cuba is better than the United States.
- Others even want to start wars.
Today, though, let’s analyze the the supposed environmentalists who think children are a net minus to society.
A professor of history at the University of Chicago, Peggy O’Donnell Heffington, has a column in the Washington Post about this topic. Here are some excerpts.

All Downside: Energy & Mineral Hungry Wind & Solar Are Simply Not Sustainable
22 Apr 2023 Leave a comment
There is no such thing as a ‘free’ lunch, some one always pays. Wind and sun may be free, the occasional power they produce is anything but.
The economic choices we make (and the policies that surround, support or reflect them) are driven by a simple equation: that the economic cost should be outweighed by the benefits on offer. And, until very recently, that equation applied with equal force to energy use and production.
As Euan Mearns puts it: “The Energy Return on Energy Invested (ERoEI or EROI) of any energy-gathering system is a measure of that system’s efficiency. The concept was originally derived in ecology and has been transferred to analyse human industrial society. In today’s energy mix, hydroelectric power ± nuclear power have values >50. At the other end of the scale, solar PV and biofuels have values <5. It is assumed that ERoEI >5 to 7 is…
