Some of the battery,or more accurately,power storage,is fantastic,and the drive systems are space-age...it is making these technologies affordable,which is the tricky part.
Making their production and de-commissioning,energy efficient and pollution-free,is where the most vocal proponents of these schemes,go all silent.
I remain,and have always been,interested and enthusiastic,in all forms of sustainability,in energy,food and human resources,but...take a common wind turbine...
It's energy output,over it's lifetime,is a statement of fact.We have built them for 50 years.
The cost and energy expenditure,in the production of the concrete,copper,steel,magnets,etc in the construction,maintenance,transport and infrastructure. Not forgetting,the pollution expended during every stage of those tasks,is another fact.
Those who laud one,whilst belittling the other,will never command either my respect,or attention.
This is the reason that many,many salesfolk,have endeavoured to sign me up,to their various nefarious,PV panel contracts,and realised the dead horse,they were flogging
One animated and exuberant fellow,got nearly to the end of his pitch,and said i could not say no,as the price of these panels were so low,due to Chinese expertise,i asked if they were made in main-land China,he nodded,i asked him what new fuel,the power stations over there,were using to power such expansion,and he replied ..."Oh,s**t..i never thought of that..."
