We are clinging to a dangerous fantasy – the belief that we can simply replace fossil fuels with something else and carry on as before. That wind, solar, nuclear, or hydrogen will allow us to keep our cars, our flights, our global supply chains, and our high-energy lifestyles. This is not just naïve – it’s reckless.

The hard truth is that there is no substitute for the scale, convenience, and density of energy we once had in oil, coal, and gas. Even nuclear power, often presented as the big solution, cannot sustain our way of life. It is part of the picture – but nowhere near the whole picture.

We must abandon the idea of energy substitution and face what really lies ahead: radical energy descent.

This means reducing our use of all forms of energy – not by a little, but by a lot. It means stepping off the treadmill of endless demand. It means redesigning our lives to need far less.

Not just fewer cars – but fewer journeys.
Not just greener homes – but smaller, simpler ones.
Not just different production – but less production.
Less heating, less cooling, less lighting, less powering.

This is not a message that wins elections or sells products. But it is the message that truth demands. The world is entering a long emergency – of resource limits, climate instability, and economic contraction. More energy won’t save us. Only using less will.

The challenge is no longer technical. It is civilisational.

And so we come to localism – not as a political slogan, but as a survival strategy.

Localism works because it cuts energy demand at the root. It shortens supply chains. It eliminates unnecessary travel. It reduces the need for global logistics, mega infrastructure, and remote bureaucracy. It rebuilds community, relocalises food and work, and makes life slower, simpler, and supportable.

We cannot keep powering the industrial scale of life. But we can power the local.

Localism is not a utopia. It is a pathway through collapse – a way of contracting with dignity. A way of living that fits within the limits of the Earth and the energy it offers.

We don’t need a new fuel. We need a new way of living.
That means less of everything – and closer to home.

Let’s get honest – and start again, locally.
