Bulk Battery Storage of Wind Power a Myth



In the fall-out over South Australia’s wind powered economic and social calamity, the line has been repeatedly spun about fixing the mess with ‘rapidly improving battery storage technology’.

It is little more than a ‘smoke and mirrors’ pitch by the wind industry, its parasites and spruikers, designed to deflect attention from the fact that wind power is meaningless as a power source, abandoned centuries ago for very obvious reasons – eg, SA’s wind power output during July:

SA Jul 16

Even if storing Terawatt/hours of electricity produced by these things – when it wasn’t needed, in order to deliver it when it might be – was technically possible the cost of the power delivered would be astronomical, as this little Mythbusting analysis makes plain.

The Cost Of Solar Power – Ed Davey’s Vanity Project


By Paul Homewood



Ed Hoskins has one of his excellent and detailed posts on renewable energy:

Comparative effectiveness of weather dependent Renewable Energy in the UK


The late Professor David Mackay in his final interview with Mark Lynas in April 2016 stated that powering the UK wholly with Renewable Energy is an “Appalling Delusion”.

In 2014 and 2015 the UK installed record amounts of Solar Energy. As a result, from being the sixth largest Solar PV installation in Europe, by 2015 the UK had increased its commitment to being the third largest in Europe after Germany and Italy.

According to David Mackay, this substantial commitment to Solar energy was made in spite of the clear professional advice, from the civil servants at the UK Department of Energy and Climate change that Solar Energy should never have been considered as useful and viable in the context of the UK…

Overestimated global warming over the past 20 years


By Paul Homewood



It’s three years old, but I don’t recall it at the time, and it’s still highly relevant:

Global mean surface temperature over the past 20 years (1993–2012) rose at a rate of 0.14 ± 0.06 °C per decade (95% confidence interval). This rate of warming is significantly slower than that simulated by the climate models participating in Phase 5 of the Coupled Model Intercomparison Project (CMIP5). To illustrate this, we considered trends in global mean surface temperature computed from 117 simulations of the climate by 37 CMIP5 models (see Supplementary Information).

These models generally simulate natural variability — including that associated with the El Niño–Southern Oscillation and explosive volcanic eruptions — as well as estimate the combined response of climate to changes in greenhouse gas concentrations, aerosol abundance (of sulphate, black carbon and organic carbon, for example), ozone concentrations (tropospheric and stratospheric), land use (for example…

Biofuels increase, rather than decrease, carbon dioxide emissions: study

Promoters of biofuel are running out of excuses for converting vast tracts of valuable farmland into fuel sources, as this Phys.org report shows. This non-solution to a debatable problem needs reviewing urgently.

A new study from University of Michigan researchers challenges the widely held assumption that biofuels such as ethanol and biodiesel are inherently carbon neutral.

Contrary to popular belief, the heat-trapping carbon dioxide gas emitted when biofuels are burned is not fully balanced by the CO2 uptake that occurs as the plants grow, according to a study by research professor John DeCicco and co-authors at the U-M Energy Institute.

Rock star-scientist Brian Cox confused on more than global temperatures


By Paul Homewood

Jennifer Marohasy launches a scathing take down of overrated TV scientist, Brian Cox:

Celebrity physicist Brian Cox misled the ABC TV Q&A audience on at least 3 points-of-fact on Monday night. This is typical of the direction that much of science is taking. Richard Horton, the current editor of the medical journal, The Lancet, recently stated that, “The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue.”
