It would be a joke if it wasn’t so expensive.

The solar industry has apparently been bragging about how much power it has been producing recently. Unfortunately, they seem to have forgotten to tell us the full story.

In overall terms, solar only generated 1.2% of UK’s electricity last year.

But worse still, in Q1, when demand is at its highest, solar only provided 0.51%.

And if that was not bad enough, when solar power does ramp up on sunny days, it simply provides problems for the grid, as this presentation from the National Grid earlier in the year showed:

The UK government has finally realised that solar power is nearly useless in the winter. Everyone else has known this all along, but better late than never. The BBC reports:

Subsidies for many new solar farms are to end under plans being published by the government.

The Department of Energy and Climate Change (DECC) is consulting on plans that would see subsidies for some new solar farms close by 2016. The government says the move is necessary to protect consumers.

Another solar theory rolls off the production line – as ever, time will tell if it lives up to its own billing.

A new model of the Sun’s 11-year heartbeat suggests that solar activity will fall by 60 per cent during the 2030s, dropping to conditions last seen during the Maunder minimum, reports Ice Age Now.

Beginning in about 1645, the Maunder minimum corresponded with the severest portion of the last
“Little Ice Age.”

Good news for solar panel makers as electricity-starved India starts on a massive expansion plan, reports Reuters (in NewsDaily):

India’s $100 billion push into solar energy over the next decade will be driven by foreign players as uncompetitive local manufacturers fall by the wayside, no longer protected by government restrictions on the sector.

The money pouring into India’s solar industry is likely to be soaked up by foreign-organized projects such as one run by China’s Trina Solar – not the country’s own solar panel manufacturers.

Another bright idea bites the dust!!

If you look back at history, you will see that it is littered with ideas that failed. It is of course the successful we are all benefitting from now.

What is different is that in those days it was not governments who picked the winners and losers.

A five-mile "Hyperloop" test project is planned for Quay Valley

A five-mile “Hyperloop” test project is planned for Quay Valley


Couldn’t see anything about energy storage in this report, so we don’t know where the power is supposed to come from at night when solar has stopped working. Maybe it’s in the small print somewhere. More about the hyperloop here.

Roy Higgs reports:
While California’s verdant Central Valley is the fastest growing area in the state, the entire population of the 22,500-square-mile region is a comparatively modest 6.5 million people — Los Angeles County alone boasts over 50% more residents. However, this single region, which is responsible for producing 25% of all of the food consumed in the United States, is expected to absorb many of the 10 million people the state is projected to grow by over the next few decades. It is also home to one of the most ambitious and distinctive new developments in modern American history: Quay Valley.

According to new research entitled: “The crucial role of surface magnetic fields for the solar dynamo”, a prediction method for solar cycles, first proposed decades ago, has been validated:
‘As the dipole field [of the Sun] is the source of the toroidal field of the next cycle, its strength should be a measure of the activity of the next cycle.’

Phys.org reports:
Sunspots, bursts of radiation and violent eruptions are signs that our sun is permanently active. Researchers have long known that this activity varies in a cycle of around eleven years’ duration. Even if many questions are still unresolved, one thing is certain: magnetic fields which emerge on the surface of our sun from within its depths are the cause of the manifold activities.

Robert Cameron and Manfred Schüssler from the Max Planck Institute for Solar System Research in Göttingen have now proved that it is possible to deduce what the internal mechanism is simply by observing the magnetic processes on the surface. This even allows predictions to be made about the strength of a forthcoming activity cycle.

Could countries heavily committed to solar power like Germany run into problems during next week’s solar eclipse?

Phys.org reports:
The first eclipse of 2015 is coming right up on Friday, March 20th, and may provide a unique challenge for solar energy production across Europe.

Sure, we’ve been skeptical about many of the websites touting a ‘blackout’ and Y2K-like doom pertaining to the March 20th total solar eclipse as of late. And while it’s true that comets and eclipses really do bring out the ‘End of the World of the Week’ -types across ye ole web, there’s actually a fascinating story of science at the core of next week’s eclipse and the challenge it poses to energy production.

But first, a brief recap of the eclipse itself. Dubbed the “Equinox Eclipse,” totality only occurs over a swath of the North Atlantic and passes over distant Faroe and Svalbard Islands. Germany and central Europe can expect an approximately 80% partially obscured Sun at the eclipse’s maximum.

But is there a cause for concern when it comes to energy production?

Read the full report here.

A wild card here could be the weather next Friday – cloudy or not.

The BBC is trumpeting a joint statement by David Cameron, Ed Milliband and Nick Clegg which spells economic doom for the UK. If ever there was a good reason to vote on May 7th for the only party committed to scrapping wind farm subsidy and nonsense ‘climate targets’, this is it.

The three stooges write Britains economic suicide note.

The battle lines are drawn for me now. Energy policy is an important element in my campaign platform. Let’s take apart the statement’s key bullet points and assertions below the break.

Our friend Vukevic called by and gave me a pointer to a links page at his site which provides a resource for those interested in studying planetary, solar and magnetic phenomena.

http://www.vukcevic.co.uk/GandF.htm

Here’s an example demonstrating the match between the sunspot number and Vuk’s planetary motion derived formulas:

Hopefully, Vuk will call back to give us some further info on his research.

Here’s another interesting correlation. The Position of the north magnetic pole has been shifting rapidly over the last several decades. The rate of change of it’s declination correlates with the variations in Earth’s length of day and the motion of the sun relative to the centre of mass of the solar system which we discussed in my first post.

North Pole rate of change of declination vs LOD vs SSBz

North Pole rate of change of declination vs LOD vs SSBz

More interesting information on Earth’s magnetism and it’s relationship with the sun here: http://www.appinsys.com/GlobalWarming/EarthMagneticField.htm

If the changes in Length of Day are related to changes in the circulation of currents of molten material beneath the Earth’s crust, we could speculate that magnetic  iron ores are shifting their predominant accumulations and this affects the location of the magnetic north pole.

This graph shows the relationship between the motion of the planets, the length of Earth’s day, and the changes in global temperature.

The Red curve shows HADcruV3 global temperature. I’ve detrended this to something more reasonable than the treasonable nonsense Phil Jones has left us with.

The Green Curve is the distance between the solar system’s centre of mass and the solar equatorial plane in the vertical ‘z’ axis. This distance is determined by the changing disposition of the planets in the solar system over time. Extra info added: The data is smoothed over 24 years (Two Jupiter orbits) and retarded 30 years. This is indicative of the inertia involved in the LOD variation lagging behind the combined effect of the gas giants motion.

The Blue curve shows changes in the Earth’s length of day in milliseconds. This has been detrended. This has been done to separate the effect of planetary motion from longer term cylicities which may affect LOD.

So, the multi-billion dollar question is:

What underlying physical principles connect these three phenomena?
Gravity? Magnetism? Resonant feedback between celestial bodies?

Answers on a postcard, or just post below with your thoughts.
