Hypothesis: During periods leading up to the onset of El Niño events, nascent Typhoon/Cyclone pairs associated with the active phase of Madden Julian Oscillations are reinforced either at or 1-2 days after the maxima or minima in the Earth’s rotation rate that are induced by the monthly lunar tides.

Ironically, the ungrateful climate responds to attempts to ‘save’ it by offering less reward to its supposed saviours. Unfortunate perhaps, but relying on weather-dependent power always will carry risks.

The warming of the Indian Ocean due to global climate change may be causing a slow decline in India’s wind power potential, according to a study, as Financial Express reports.

India, the third largest emitter of greenhouse gases behind China and the US, is investing billions in wind power and has set the ambitious goal to double its capacity in the next five years, said researchers from the Harvard John A Paulson School of Engineering and Applied Sciences (SEAS).

The spirit of Heath Robinson lives on.

The experimental device is part of the secretive Google X research lab, reports Euronews.

One day, generating renewable energy could be as simple as flying a kite — but not just any kite.

After more than a decade of development work, an experimental “energy kite” capable of tapping into strong high-altitude winds is now being tested on Hawaii’s Big Island, West Hawaii Today reported.

This report from the WHO ought to be hard for wind power promoters and their ideology-bound supporters to ignore.

STOP THESE THINGS

The World Health Organization’s declaration that wind turbine noise is a serious health hazard, is a liability bombshell for developers and governments, alike.

No longer can wind power outfits and those that make a living running propaganda for them claim that ‘there’s nothing to see here, move on.’ The wind industry’s victims – mocked and denigrated for years – have been vindicated. Now comes the vengeance. Litigation is already on foot in Victoria, with more claims to follow.

The significance of the WHO’s new noise guidelines hasn’t been lost on STT Champions Alan Jones and Liberal MP, Craig Kelly.

STT highlights the ‘tension between economic energy and politically correct energy’.

No amount of money or technology can force the wind to blow on demand.

The spinning wheel was meant to signify Indian independence, too.

It never takes them long to work out that wind power is the greatest economic and environmental fraud of all time. Eco-zealots have attempted to ram wind and solar power down the throats of Third World governments under the auspices of saving the planet and purportedly with the purpose of dragging millions out of poverty. As the initiated well-know, wind power rates zero on both scores. Pointless and expensive, wind power is a kind of first world disease being spread by UN endorsed lunatics, across the developing world.

In India, solar power is seen as ‘fake electricity’, by those being forced to use it: The Cruel Hypocrisy: West Drops Wind Power as it Forces ‘Fake Electricity’ on the World’s Poor

Now, Indians have branded wind power an outright fraud, too. The calm, and very wet weather that comes with the monsoon…

Descending air in the atmosphere rises in temperature as it is adiabatically compressed in the pressure gradient created by gravity acting on atmospheric mass. This has been known for centuries. However, the MET Office has decided to do away with this fundamental fact of physics in a short video it has produced.

Even their own website page on the Foehn effect (now safely screenshotted and web-cited) tells us:

“ foehn air… becomes warmer and drier on the leeside after it is compressed with descent due to the increase in pressure towards the surface.”

The researchers report that ‘Titan displays particularly energetic meteorology at equinox in equatorial regions’. Associated strong winds ‘are expected to occur in downbursts during rare equinoctial methane storms—consistent with the timing of the observed brightenings’. On Earth, auroral activity is strongest at the equinoxes, so solar wind strength could be a factor in both phenomena.

Data from NASA’s Cassini spacecraft has revealed what appear to be giant dust storms in equatorial regions of Saturn’s moon Titan, reports Phys.org.

The discovery, described in a paper published on Sept. 24 in Nature Geoscience, makes Titan the third Solar System body, in addition to Earth and Mars, where dust storms have been observed.

This is an updated version of an article that’s appeared before, but as it covers quite a lot of ground is worth airing.

TRYING to pin down the arguments of wind promoters is a bit like trying to grab a greased balloon, writes John Droz, Jr. .

Just when you think you’ve got a handle on it, it morphs into a different story and escapes your grasp. Let’s take a quick highlight review of how things have evolved with merchandising industrial wind energy.

Good luck to the mission. A somewhat optimistic claim made here is that this will ‘improve our understanding of manmade climate change’ but, as the report states without noting any irony, the name of the mission is drawn from mythology.

A satellite designed to measure Earth’s global wind patterns is set to be hoisted into orbit Tuesday from the Arianespace launch site in French Guiana, reports Phys.org.

The European Space Agency’s (ESA) Aeolus mission—named for the guardian of wind in Greek mythology—promises to improve short-term weather forecasting and our understanding of manmade climate change.

Note that ‘despite a great deal of press, wind and solar make up less than 3 percent of U.S. energy consumption.’

Intermittency, high cost of subsidies and requirement of suitable land are just some of the reasons for that.

The wind’s fickleness is no mystery to kite flyers and sailors, yet wind power still gets pumped as if it’s cutting edge technology.

Those few places attempting to run on nature’s wonder fuels have become economic debacles. One of those, RE ‘superpower’, South Australia has suffered routine load shedding for years, and rocketing power prices. South Australians pay the highest power prices in the world and SA is the only Australian state to suffer a statewide blackout.

South Australia’s maniacal obsession with wind and solar power sees it pick up a special mention in the pointed little video above, and is further detailed in this brilliant piece by Kenneth Haapala from the US of A, below.

Venus


The apparent length of day on Venus (116.75 days) is nothing like its rotation time (~243 days), due to its retrograde spin. It can be stated as the time in which the sum of the number of Venus orbits (~0.52) and spins (~0.48) in the period equals 1.

As ScienceNewsforStudents reports, the thick atmosphere on Venus can change by a few minutes every day how long it takes the planet to rotate.

Time gets tricky on Venus. The planet has extremely thick air, which flows much more rapidly than the rate at which the solid planet spins.

As that thick atmosphere pushes against the planet’s mountains, it can change how quickly Venus spins, scientists now report.

Optimism – or is it wishful thinking? – may not be unusual among so-called greens, but merely hoping for solutions after creating the problems doesn’t look like much of a strategy.

Germany has more than 28,000 wind turbines — but many are old and by 2023 more than a third must be decommissioned. Disposing of them is a huge environmental problem.

Expert Jan Tessmer (coordinator on wind energy research at the German Aerospace Center (DLR)) tells DW he’s optimistic.

Another example of the obvious inadequacy of part-time unpredictable wind power, and its consequencies for countries that insist on pursuing it. Relying on imports to avoid power shortages can’t be ideal for any country.

Sweden will have to import more electricity during winter as the country, a net power exporter to the rest of Europe, shifts from nuclear to wind, its grid operator said.

The report says ‘local media reports suggested the turbine was struck by lightning’. A case of nature’s electricity killing man’s electricity?

A Gamesa G80 wind turbine has caught fire at the 10MW Ransonmoor wind farm in Cambridgeshire in eastern England, reports RE News.

The incident occurred in the early hours of 30 May, with firefighters called to the scene at 7.50am.

Cambridgeshire Fire & Rescue Service said crews arrived to find the 89-metre turbine “well alight, with debris falling to the ground”.

Have scientists been looking through the wrong end of the telescope, so to speak, regarding ice ages theory?

Ancient rainfall records stretching 550,000 years into the past may upend scientists’ understanding of what controls the Asian summer monsoon and other aspects of the Earth’s long-term climate, says EurekAlert.

Milankovitch theory says solar heating of the northernmost part of the globe drives the world’s climate swings between ice ages and warmer periods.

The new work turns Milankovitch on its head by suggesting climate is driven by differential heating of the Earth’s tropical and subtropical regions.

This could be a step forward in unravelling the whys and wherefores of the phenomenon of jet stream blocking.

The sky sometimes has its limits, according to new research from two University of Chicago atmospheric scientists.

A study published May 24 in Science offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region, reports Phys.org.

Much like highways, the jet stream has a capacity, researchers said, and when it’s exceeded, blockages form that are remarkably similar to traffic jams—and climate forecasters can use the same math to model them both.

Good luck dismantling and trying to recycle redundant end-of-life wind turbines and their massive concrete bases.

New academic research on whether to repower or extend the lifetime of an obsolescent wind farm in Europe reveals that without new subsidies for repowered sites, low cost lifetime extensions focused on maximising return before decommissioning are more probable, with a potential to affect about half the wind turbine fleet in Germany, Spain and Denmark.

In the absence of new subsidies, we could be looking at the beginning of the end for the wind industry in Europe, says The GWPF’s energy editor.

The original technology was demonstrated in an Atlantic crossing that took place in 1926, but Norsepower says it has created various new improvements for which several patents have been granted.

Last year (reports New Atlas) we detailed how Norsepower had rediscovered an engineering innovation, which sees large cylinders installed atop big ships to harness wind for propulsion.

Now a passenger ship has been treated to the Rotor Sail Solution and has set sail on wind-assisted trips between Finland and Sweden.

The M/S Viking Grace – which has 880 cabins and can accommodate 2,800 passengers and around 500 cars – went into service in 2013, when it was reported to be the first ship of its size to be fueled by Liquefied Natural Gas (LNG).

Introduction

This post is concerned with the two main forms of UK Weather Dependent Renewable Energy in the UK, Wind Power, (Onshore and Offshore), and on grid Photovoltaic Solar Power.  In the UK these amount to ~75% of all installed Weather Dependent Renewable Energy.  The other Renewable energy inputs are traditional Hydro power ~8% and the remainder are other sources such as biomass, waste and landfill gas amounting to ~17%.

The capacity percentage, or load factor, of any power generating installation is calculated as the actual electrical output achieved annually divided by the nominal maximum Nameplate output.  This article uses the real measures of capacity reported in up to date time series data of UK Renewable installations.  It thus provides reasonably correct comparisons of the efficacy of Weather Dependent Renewables as is reported annually by the Renewable Energy Foundation in the UK.
