Every answer has a cost. Every choice exacts a penalty. A new book reminds readers there are no easy answers to the climate crisis.
LONDON, 24 June, 2019 − Resolving the climate crisis demands radical political change, a British author argues: the end of free market capitalism.
You could turn the entire United Kingdom into a giant wind farm and it still wouldn’t generate all of the UK’s current energy demand. That is because only 2% of the solar energy that slams into and powers the whole planet on a daily basis is converted into wind, and most of that is either high in the jet stream or far out to sea.
Hydropower could in theory supply most of or perhaps even all the energy needs of 7 billion humans, but only if every drop that falls as rain was saved to power the most perfectly efficient turbines.
And that too is wildly unrealistic, says Mike Berners-Lee in his thoughtful and stimulating new paperback There Is No Planet B. He adds: “Thank goodness, as it would mean totally doing away with mountain streams and even, if you really think about it, hillsides.”
This is a book for people who really want to think about the state of the world, and how to get to zero-carbon emissions as swiftly as possible, and in a way that preserves a decent life for the 11 billion or so who will people the planet by 2050. And, of course, everything boils down to energy
Enough for everyone.
The sun delivers around 16,300 kilowatts to the Earth’s surface for every person on the planet: enough, he says, to boil an Olympic-sized swimming pool of water for each and every one.
