That article states:
"The UK is already doing well on renewables. Latest figures show that in 2020 they
collectively generated around 45 per cent of our electricity, up nine per cent on 2019. "
Garbage: summer only.
And then goes on about the need for rare elements for super strong magnets needed for wind power:
"As these rare elements are distributed in tiny quantities, vast piles of ore need to be
dug up, processed and refined to produce minuscule amounts. For a single kilo of
gallium – used in energy-efficient light bulbs – 50 tonnes of rock needs to be
excavated, according to Pitron."
I take it from that the writer knows nothing about mining in the real world...eg gold
"GOLD: One ounce, or roughly 30 grams/tonne is high-grade and can be expected to move markets in most cases. Several ounces of gold per tonne is considered to be high-grade for underground mining, although 5 grams gold/tonne is usually economically viable."

His article is just full of facts presented as "bad" when other minerals are just as difficult to extravt
