No different to growing hay and oats for the horses. It is said that 1/3 of the output of a lowland farm was dedicated to keeping the working horses.
I like that bit , just wondering how they make the crops payBe thankful it takes ground out of the equation that would otherwise grow more wheat or barley.
Doing you all a big favour @bobk
Ethanol , there's another , burning diesel to make less diesel

Presumably when the methane produced from AD is burnt it produces carbon dioxide?
I see they had to bring in lots of generators to keep the electric cars charged at Cop 26

malting and distilling isn't food production really....just making piiss
Geezer from the beeb drove up in an electric car , took him 12 hours ...... probably got lost after Watford
It's pi55 that people buy though

as opposed to electricity they don't?
....in fact they need leccy more than booze surely?You don't understand , leccy is free , cider needs coins .as opposed to electricity they don't?

Makes you laugh that the government subsidised “concrete cows” a few years back to make energy renewable via burning “sustainable” methane.
Yet now are vilifying actual cows for the same biological process….

The theory is that the plant has absorbed CO2 from the atmosphere it the first place, therefore it is returning it to whence it came, unlike burning gas that's been buried for thousands of years. Of course, that ignores the all the non-bio diesel currently burnt in the tractors to produce the crop and any carbon extracted from the soil....

Sounds remarkably like the arguments that we use for ruminants which are consistently ignored!

It’s also the same as the natural process that takes place in a cow’s stomach…..which yesterday and today has been paraded in front of the conference as part of the methane “problem”.

Cows are largely farting out methane, whereas AD is burning the methane & releasing CO2. Methane is believed to have a greater effect on climate change than CO2. From my understanding of the science it is plausible, but the volume of methane & its effect in comparison to the effects of the CO2 released in pursuit of tourism is another matter!
Globally speaking, cows are fed lots of soya & concentrates etc. & that either involves lots of artificial fertiliser or burning down the rainforests both of which is releasing masses of carbon into the atmosphere that was otherwise sequestered elsewhere.
There is beginning to be a bit of recognition that cows in the UK tend to be grass fed & less reliant on soya etc, but the same cannot be said of elsewhere & the numbers don't stack up very well for maintaining the same level of global consumption by relying solely on grass fed etc.
