Anaerobic Digestion makes slurry yield nutrients in a way that is multiples more efficient than slurry that has not been put through the digester. AD slurry does not smell to the same extent as raw slurry. AD slurry is better suited to slurry injection than raw slurry.
And the farmer gets to sell renewable electricity to the grid, as well as an abundant supply of hot water - build a couple of glasshouses and get into the veg business on the cheap.
The Greens' policies are all about looking into the future, spotting the threats and opportunities, and planning the most effective way to deal with them.
Scary, isn't it?
What a load of nonsense !. Would you please stick to topics about which you know something !
Anaerobic digestion (AD) converts about 20% of the gross energy of organic matter (manure, fodder, waste) into biogas. Of this at most 40% is converted into electricity i.e. 8% of the gross energy in the orginal feedstock. Add in the capital cost 1.5million to 2.0 million Euro for two plants I have seen and you realise that it is a far from cheap source of electricity. In addition both plants expect aboyut 10 to 20% "down time" when gas is flared-off (burnt) to atmosphere.
In Germany, Italy and Denmark producers of "green electricity" are paid 18 to 20 cents per Kwh for electricity supplied to the grid and the reail price of electricity is about 12 cents per Kwh.
So, the consumer is ripped off to support a green agenda.
If you want to conserve energy or generate from waste you will incinerate it (instead of landfill) and recover 20 to 40% of the energy and use animal manure to replace some of the chemical fertiliser.
This stuff is not rocket science !!
Re windmills (from another poster), it takes about 25 years (yes twenty five) to recover the installation cost / carbon foot print.
Another tax scam !!
