Solar overload — “Costs a fortune” as the super Duck Curve flood of electricity hits Australia

Ladies and Gentlemen, Australia is now romping in as Star-Crash-Test-Dummy in the renewables stake.

Proportionally, we have more uncontrolled solar roof top generators than any other nation. We’re in uncharted territory: about 20% of houses in Hawaii and California have Solar PV, but in Western Australia, it’s 25%. In Queensland it’s 30% and throughout Australia we are adding 100MW a month and it’s like a whole new coal fired station every year (except it doesn’t work most of the time).

Strap yourself in! This is more useless infrastructure than anywhere else on planet Earth. The only time solar PV panels provide something we might need is at afternoon tea time in summer when airconditioners are on. So for three quarters of the year they provide electricity when we don’t need it, and for three quarters of every day they don’t even work. The rest of the time they burn capital, increase the blackout and fire risk and sit there collecting dust and hail stones.

Electricity at the wrong time is not just wasted, it’s a burden

Too much electricity bumps up the grid frequency and voltage, potentially damaging equipment and risking blackouts. Obviously we have to “manage” this flood of [...]

Now that was “climate change” 8200 years ago — California lashed by 150 years of storms

Don’t tell me that cold is nice and the climate was ever ideal

A few scientists thought that the climate was stable and well behaved during the Holocene until we invented coal power and the Ford Model T and everything fell apart “unprecedentedly”.

But 8200 years ago things apparently got pretty wild. See the GISP graph below where there was a three degree fall in temperatures suddenly (circled in red below). A new study found that at the same time China and California also cooled. Strangely, this cooling effect probably did not produce calm, happy days for the Californians at the time. Instead it looks like they got 150 years of intense winter storms and a lot of wet weather.

UPDATE: This graph shows the ice-core data up until 1855. The last 150 years (1705 to 1855) are highlighted in red to show the warming as the Earth began coming out of the LIA. Obviously that red line would continue up further if it was drawn to the present.

Looks like real climate change….

The reason for the sudden snap is possibly that a couple of massive glacial lakes in North East America collapsed and suddenly drained out [...]

Let’s copy California and have less jobs, less money, less energy. Feel that Green Glory!

NSW (and a lot of Australia) is a closeted corner of the world where electronic news can take decades to arrive. The electrons themselves make it downunder in 150 milliseconds or so, but the message may never make it past the ABC-Fairfax filter. Apparently the highest office in NSW wants to emulate California. It’s like it’s 1994.

“When it comes to clean energy, we can be Australia’s answer to California.”

– Rob Stokes, NSW Environment Minister.*

Maurice Newman sets him straight in The Australian.

In short –  companies are fleeing from a green California to Texas where electricity is half the price. For some reason jobs, profits, products and opportunities are following the energy. California’s unemployment rate is 7.4%. Texas’ is 5.1%.

California dreaming is nuts in NSW

“The NSW government must also be oblivious to the steady exodus of Californian businesses and jobs. Companies like Toyota, which after 60 years has moved its US headquarters to Texas, or Occidental Petroleum, which after 50 years has left for Houston. Chevron is next. Other stalwarts like ARCO, Getty Oil, Union Oil, Fluor, Calpine and Intel have all moved in search of a more business friendly environment and [...]
