Wind and solar are parasitic power producers, unable to survive in a modern electricity grid without the back-up of stand-alone electricity generators such as hydro, coal, gas or nuclear. And like all parasites, they weaken their hosts, causing increased operating and transmission costs and reduced profits for all participants in the grid.
Without subsidies, few large wind/solar plants would be built; and without mandated targets, few would get connected to the grid.
Green zealots posing as energy engineers should be free to play with their green energy toys at their own expense, on their own properties, but the rest of us should not be saddled with their costs and unreliability.
We should stop promoting parasitic power producers. As a first step, all green energy subsidies and targets should be abolished.
“For the Greens, a pristine global environment represents earthy perfection. It underpins their ‘ecological wisdom’ and is at the core of the new ethic. It is to be protected and promoted at all costs. Hence, all old growth forests are to be locked up; logging is to be prohibited; wealth is to be scorned; economic growth is opposed; exclusive ownership of property is questioned; there should be a moratorium of fossil fuels exploration; dam construction should be discouraged; genetic engineering and agricultural monoculture is rejected; world trade should be reduced; and a barter economy encouraged.”

As we watch the disturbing daily images of a dry Darling River, parched Menindee Lakes, millions of dead fish, and outback towns without drinkable water, both bush and city are screaming – Why?
Who is responsible they ask? Name the scapegoats and brand them criminals is demanded.
Any lesser response would be shameful, but some reactions, while understandable, are not rational.
Before we look more closely at why and how these unacceptable events have occurred, we need to put to rest some misconceptions about this river and recent claims made by some aboriginal people that the Darling was previously a “Mighty River” that always flowed.
It wasn’t. After discovery by English explorers Stuart and Hume in 1828, history kept at Menindee tells us it was bone dry there at least 48 times up to 1960 – something that no doubt also happened for hundreds of years before.

71% of the earth’s surface is covered by water and large areas of the land are covered by frozen water. Water and water vapour are also significant components of the atmosphere.
The atmosphere and its trace component of carbon dioxide is a very thin skin in close contact with the surface of all of this water. Carbon dioxide is very soluble in water and Henry’s Law says that as the temperature of water changes the quantity of carbon dioxide dissolved in that water will change.
Thus if the sea surface temperature increases, carbon dioxide will be expelled to the atmosphere just like carbon dioxide bubbles are expelled from a warming beer. And as sea surface temperature falls, carbon dioxide will dissolve in the cooling water and this reduces the carbon dioxide in the atmosphere.
This effect can be seen in seasonal, medium term and long term trends.
The seasonal variation in atmospheric content of carbon dioxide is well known, and the huge southern oceans are key players. See the short paper by Bob Beatty on the carbon dioxide cycle at : http://www.bosmin.com/HenrysLaw.pdf [PDF, 689 KB]
When it is winter in the southern hemisphere, the cold surface water of the oceans absorb carbon dioxide and the content of carbon dioxide in the air falls suddenly by about 4 ppm. This is reversed when the southern oceans warm in summer, and the carbon dioxide is expelled from the oceans. (The seasonal summer growth and winter fall of northern hemisphere vegetation adds to this seasonal fluctuation caused mainly by the southern oceans.)
On a medium time scale (21 year moving average) Professor Lance Endersbee published a short paper in August 2008 and he concluded that the oceans regulate the carbon dioxide in the atmosphere and the influence of human-generated carbon dioxide in the atmosphere is negligible. His paper included the following diagram:
On longer time scales, ocean mixing caused by deep ocean currents causes long term changes in ocean temperatures. These changes also affect long term carbon dioxide trends. Carbon dioxide held in large quantities in cold deep ocean water is slowly released as ocean currents mix this cold water with warmer surface water. The reverse occurs as the sea surface cools, absorbs carbon dioxide and the cold dense water sinks to the ocean floor.
The most dramatic evidence of this lagged response comes from ice core data. These show that significant turning points in temperature precede the corresponding turning points in carbon dioxide content in air by between 650 and 1600 years.
Henry’s Law can and has been tested in laboratory experiments. The other data provides additional evidence for the conclusion that the major factor regulating carbon dioxide in the atmosphere, on all time scales, is the temperature of the oceans. Ocean temperature is controlled by solar cycles, cloud cover, ocean currents and undersea volcanism.
The Global Warming Policy Foundation has published (May 2011) a detailed report about the shale gas revolution and its likely implications for climate policy.
The report , written by Matt Ridley and with a foreword by Professor Freeman Dyson, finds that shale gas:
is not only abundant but relatively cheap and therefore promises to take market share from nuclear, coal and renewable energy and to replace oil in some transport and industrial uses, over coming decades.
will help to keep the price of nitrogen fertiliser low and hence keep food prices down, other things being equal.
is unlikely to be a major source of pollution or methane emissions, but in contrast promises to reduce pollution and accelerate the decarbonisation of the world economy.
Naturally, after causing a boom in demand for gas, and promoting it, greens are now trying to prevent exploration and exploitation of this massive new energy source. And just as naturally they are being supported by competitive energy sources threatened by this gas bonanza – French nuclear, Russian gas, the coal geo-sequestration crowd and the whole wind/solar lobby.
Some of these shales will also produce significant oil. Nick Grealy looks here at the coming impact of oil and gas from “Wet Shale”:
We all know the maxim that common sense just isn’t that common. Nothing proves this more than the current debate about Climate Change. ‘Global Warming’ has become the propaganda term of choice for those who make a living from scare tactics about the climate. Yet, brave souls in the scientific and political community are offering alternate views, views that receive scant regard in the mainstream media.
In a series of columns for carbon-sense.com we will investigate just how much, or little, common sense is being applied in the worldwide debate. We will expose the facts Al Gore and his cohorts don’t want the average citizen to know; and we will challenge the orthodox view that has enveloped the mass media and politicians of all stripes. More importantly, we will investigate the motivations of many of those who are on the climate change bandwagon – from simple economic avarice right through to an intent to alter the entire economic and political order.

Playing Snakes and Ladders with Australia’s Electricity Supply. By Viv Forbes & Helpers
Every day some green energy promoter or a battery salesman tells us how green energy with battery backup will supply Australia’s future electricity needs.
A battery stores energy. Energy can be stored using lead-acid, nickel/cadmium, lithium, molten salt, pumped hydro, hydrogen, flywheels, compressed air or some other smart gizmo. But NOT ONE battery produces new energy – they simply store and discharge energy produced by other means.OnePlus 5 specs They all deliver less energy than they consume. Moreover, to manufacture, charge, use and dispose of batteries consumes energy and resources.
The idea of producing reliable grid power from intermittent green energy backed up by batteries looks possible in green doodle-diagrams, but would be absurdly inefficient and expensive.
Solar works a Six hour day
Consider a solar panel which is rated to collect say 100 units of energy per day at full capacity, in full mid-day sunlight, with a clean panel, properly aligned to face the sun.
No solar energy arrives overnight and only minimal amounts arrive during the three hours after dawn or before dusk. That means that significant solar energy can only be collected for about 6 hours per day, providing it is not cloudy, raining or snowing. No amount of research or regulation will change this – the solar energy union only works a six-hour day and takes quite a few sickies. So instead of feeding 100 units of energy per day into the grid, at best, the panel supplies just 25 units.
Can the addition of batteries give us 24/7 power from solar?
To deliver 100 units of energy in 24 hours will require an extra 75 units of energy to be collected, stored and delivered by the batteries every sunny day. This will require another three solar units devoted solely to re-charging batteries in just 6 sunny hours.
Cloudy/wet days are what really expose the problems of solar plus batteries. (This is why isolated green power systems must have a diesel generator in the shed.)
To insure against, say, 7 days of cloudy weather would require a solar/battery system capable of collecting and storing 700 units of energy while still delivering 100 units to consumers every day. However if several consecutive weeks of sunny weather then occur, this bloated system is capable of delivering 7 times more power than needed, causing power prices to plunge, driving reliable generators out of business and wasting the life of solar panels producing unwanted electricity. 192.168.l.254
Solar energy obviously does best in sunny equatorial deserts, but that is not where most people live. And the huge Desertec Solar Power Dream for the northern Sahara has failed.
The report card on wind energy is different, but equally depressing.
When Australia had reliable, predictable coal-gas-hydro power in every state, the need for heavy interstate transmission was minimal. But green power will require robust and costly interstate transmission facilities to send large amounts of power at short notice from sunny coal-rich Queensland to cloudy Victoria, windless South Australia or droughted Tasmania.
It seems that a self indulgent government has already spent much of the money it will raise with a tax on carbon dioxide – on promoting its own agenda.
Most recent is the Flannery “Climate Commission” soaking up $5.6 million. Then the Garnaut Review of the Garnaut report. Then the well staffed experts serving the Green/ALP coalition’s “multi party committee on climate change”.
Then all the juicy jaunts to the never ending international conferences in all the world’s best resorts.
As Alan Moran, says using tax payer funds to convince tax payers to part with more funds is the hallmark of the state where nanny knows best.
