The penny is fast dropping that by far the most disastrous appointment made by David Cameron to his Coalition Cabinet was that of the ultra-green, Lib Dem millionaire Chris Huhne as our Secretary of State for Energy and Climate Change.
Yesterday, after Mr Huhne issued his first annual statement on Britain's energy future, it was clear that we should all be very, very concerned about the future of Britain.
As was only too predictable, the overall theme of Mr Huhne's message was that 'climate change is the greatest global challenge we face'.
We must do everything we can and more to cut down very drastically on our 'carbon emissions', as we are now legally committed to do by the Climate Change Act - at a cost of £18 billion a year.
But in the real world, the £100 billion-plus energy question that confronts us all in Britain today is how we are going to fill that massive, fast-looming gap in our electricity supplies when the antiquated power stations which currently supply us with two-fifths of the power needed to keep our economy running are forced to close.
The headline answer given by Mr Huhne is that we must build thousands more giant wind turbines.
As a 24-carat green ideologue, he is viscerally opposed to replacing the ageing nuclear and coal-fired plants which currently provide us with more than half our electricity.
Like Tony Blair and Gordon Brown before him, he dreams we can somehow fill that gap by erecting 6,000 wind turbines in the seas around Britain's shores, and thousands more across many of the most beautiful parts of our countryside.
What is truly terrifying about Mr Huhne as our energy minister is that he seems so astonishingly ignorant about even the most basic principles of how electricity is produced.
He boasts about how the 3,000 wind turbines we have already built have the 'capacity' to generate 4.5 gigawatts of electricity.
Capacity is the crucial word here. As he could see from figures on his own department's website, thanks to the fact that the wind blows only intermittently, the amount of power these windmills actually produce is barely a quarter of that.
In other words, the amount of electricity generated by all those turbines put together, at a cost of billions of pounds, is no more than that provided by a single medium-size conventional power station - equivalent to a mere two per cent of the electricity we need.
He then talks about how we must build thousands more turbines around our coasts - when, as any responsible civil servant in his ministry could tell him, there is no way we could hope to build more than a fraction of the number he is dreaming of, even if we had all the money in the world.
The target set by the last government would require us, at a cost of £100 billion, to erect nearly two of these monster turbines, each the size of Blackpool Tower, every day of every week for the next ten years - when each takes weeks to manufacture and sink into the seabed.
But even if Mr Huhne could make his dream come true, that would still supply on average only five more gigawatts of electricity, less than a tenth of our needs.
Meanwhile, to keep the lights on, a whole lot more gas-fired power stations would have to be built - and kept running, pumping out CO2 - simply to be ready to be ramped up to fill the gap when the wind stops blowing.
The Huhne solution to producing Britain's energy is naivete verging on madness.
