Political News-Ed Miliband Guardian Article One giant leap for a greener Britain

Only an Apollo-like effort of imagination and action will help us move to a low carbon economy

Forty years since the Eagle landed on the moon, the idea of a new Apollo project has become shorthand for how we should tackle climate change:
politics forcing through the technological limits, a decade-long push, and a nation unified for a shared goal. The Guardian's Manchester Report last week showed there are plenty of reasons for optimism about the technologies that can take us into the low-carbon future.

But like Apollo, the challenge of climate change is to combine political will with technological leapfrog – and, in fact, the political challenge is almost unparalleled in human history. We can't all be rocket scientists (or climate scientists), but every one of us is needed for the political moonshot of today.

If the world agrees to act on climate change at the Copenhagen conference in December, countries will need to maintain their radicalism not just for a year or two but for decades. There must be a consensus from the richest country to the poorest and from democracies to autocracies. When we all depend on each other's actions, the world can't afford climate free-riders.

At home, our consensus already stretches from businesses to trade unions and from the Women's Institute to MTV. But for the pace and breadth of change that is needed many more people must be won over to our cause – to make change themselves and to build a climate change consensus. Climate change denial is given short shrift, but we should not confuse widespread acquiescence for universal enthusiasm. Climate change champions face the classic test of take-off political movements: how to widen the circle of the committed without watering down the clarity of the message.

First, if we are in the persuasion business, all of us have to talk as much about the advantages of the low carbon choice as the disaster that awaits if we don't act. We don't do this enough.

Just look at energy. Two-thirds of the world's gas is in Russia and the Middle East, but renewable energy is homegrown and can help us stem a rising dependence on imports. In manufacturing, there is a thriving set of new industries dependent on low carbon and on ways of cleaning up old sectors, and a chance to build a broader-based economy. Only by making the transition, with government support, can we reap the benefits.

And let's use the moment and cause to think about how we design cities and towns to make it easier for people to enjoy greener space, use public transport and have a better quality of life.

Second, we need not just to appeal to people to change their lifestyles but make it easier for them to do so. Here government has a central role. What will make more people leave the car in the garage and take a bike to the train station? Not finger-wagging, but convenience. As Andrew Adonis, the transport secretary, pointed out last week, the Dutch town of Leiden has three times as much bike storage at its station as all the London terminals put together. In Holland a third of journeys to stations are by bike; in Britain it's 2%. And from bike racks to loft lagging, the UK Low Carbon Transition Plan is designed to help make it possible for people to find a better way.

Third, we need to win some big and difficult arguments to create consensus. To do this we need to be candid about the pressures created by the transition to low carbon and show we will try to alleviate them where we can.

When I launched the plan, last week, I said energy prices were likely to rise by 2020. We need to convince people that despite the costs, the transition is right because the costs of not acting are much greater, and high-carbon fossil fuels offer an insecure future. We need to find ways of making the transition as fair as we can, insulating particularly the poorest people from these effects.

I believe the biggest threat to the countryside is not wind turbines but climate change. We do need to site new turbines in the most appropriate places, but we also need to persuade people that they have to go somewhere, and that the catastrophe wrought by climate change would indeed destroy many parts of our green and pleasant land.

However, building the resolve of a country, let alone a planet, is a big ask. Change happens not just because leaders want it, but because people demand it.Groups are springing up to persuade people to act on climate change. They ally the power of imagination – the rocket on the moon – with the power of example, action in their own lives.

They must also be the kernel of the movement, sustained and broad, that we need to exert pressure on governments up to Copenhagen and beyond. While this week we celebrate Apollo, it is persuasion, campaigning and political argument, not just technological advance, that will generate the giant leaps humankind needs on climate change.

Client News-Marine Current Turbines are selected in the top ten of the Guardian Manchester Report on Clean Energy Technologies

Marine energy

Marine turbines are like underwater windmills than can extract energy from fast-flowing tides or deep ocean currents

A huge amount of energy is stored in, on and above the oceans. Strong sea winds can be exploited with offshore windfarms, while waves can be converted into electricity using articulated snake-like generators. Scientists and engineers are also exploring how to create electricity from the salinity difference between rivers and oceans and the temperature difference between the sea surface and the colder waters below.

One of the most promising marine energy technologies is the tidal turbine, which was advocated in Manchester by Peter Fraenkel of Marine Current Turbines (MCT). These devices act like underwater windmills, with blades that rotate as the tide flows through them. Tidal turbines create large amounts of power in those countries with very fast-flowing tidal streams – such as the UK and Canada – and in the future similar devices could be used to extract energy from deep ocean currents such as the Kuroshio in north-west Pacific.

Compared to wind and solar energy, tidal generation has the advantage of predictability. Being driven by the gravitational pull of the moon and sun, as opposed to the weather, their timing and strength is known in advance to a high level of certainty. A further advantage is the high energy density of the tides. With as much as a thousand tonnes of water passing through a turbine's blades in a single second, a relatively small device can create a relatively large amount of electricity.

Producing devices robust enough to withstand these forces is a formidable engineering challenge, but MCT's flagship device – the SeaGen – has already been proven to work on a commercial scale. Positioned in Strangford Lough, Northern Ireland, the first SeaGen turbine has generated more than 100 megawatt hours of electricity.
