China Syndrome: Britain Gets Left Behind in the Renewables Revolution

China has been leading the way in global investment in clean, renewable energy for several years now.
Any Green will have encountered it, either on the doorsteps, or in debate or in the rightwing press.
Renewable energy - it's a waste of time because even if we cover our landscape with solar panels and wind turbines, it won't make any difference because of the Chinese (and sometimes, for good measure, the Indians as well). As these countries industrialise and prosper, we are repeatedly told that it is on the back of coal, oil and gas energy sources - so many new coal power stations a week, easily blowing our puny efforts to clean the planet out of the water.

So, we might as well not bother and just keep burning away as much carbon, methane and other warming gasses as we like. Those who say otherwise are attacked as selling out to some global scientific conspiracy, or making elderly people freeze in winter because of allegedly higher "green" energy taxes and so on. It's just not British.

On cue, this week, the "greenest ever Government that never was", the Lib Dem-Tory Coalition, is phasing out subsidies to help get larger scale solar power schemes off the ground in the UK, just at the time solar panels are becoming exponentially more efficient and effective, and 70% cheaper. So although he could get much more power for our money, Lib Dem Energy Secretary Ed Davey is pushing forward with leaving solar to the whims of the free market in spite of pleas from the sector that it will quickly become unviable, at best stalling the gains of recent years. At the same time, massive tax breaks worth £1,300,000,000 in the next year are to be given to oil companies that extract oil from the ground at a cost of significantly less than $2 per barrel but sell on at apparently rock bottom prices of $55 per barrel, which is just not enough profit for the poor billionaires to get by on.

But the fact is that the arguments about China and India are no longer true, if they ever really were anything other than (no pun intended) a smokescreen for the oil lobby to entrench itself ever deeper over here.

China is now the world's biggest investor in green energy and renewables now account for over 30% of its electricity generation.(compared to around 12% in the UK). Its current investment will drive this ever upwards over the coming years, putting it way ahead of the fracking-seduced USA. Its primary goal is energy security - China has recognised what so many corporately-owned western governments cannot dare to whisper within earshot of their big business sponsors: sticking to carbonised energy isn't just polluting the planet, it is undermining the independence of nation states.

China's endemic pollution is driving a major shift to clean energy
 China does have other considerations too - as its economy continues to expand, it does continue to consume the largest amount of coal of any country, but this is falling quickly as a proportion of its energy use and is intended to be cut ever deeper. Chinese citizens have been alarmed by repeatedly persistent and thick smogs enveloping their cities in the summer and while as monolithic as ever, the Government is responding. And it is a question of scale - per head of population, China emits about half the carbon that Britain does and barely a quarter of the USA's per capita emissions.

As for India, per head of population, it produces barely 3 tonnes of carbon emissions per person per year - compared to 5 tonnes in China, 8.5 tonnes in Britain and more than double that in the USA. But its government too is investing heavily in renewables with the Modi government quadrupling an already ambitious solar energy target for 2022.

Just think how different and truly independent our foreign policy could be if we no longer relied on oil from Saudi Arabia and the Gulf, or gas from Russia, for our energy requirements. No more oil equals no more oil wars as well as potentially no more global warming.

But no, our rightwing so-called patriots, who denounce Greens and other environmentalists in increasingly shrill terms, are quite happy for us to continue to depend on President Putin and King Salman for our lighting and heating and the civilised life electricity provides. And so, consequently, we remain beholden to, entwined with and dragged down into endless threats and conflicts by some of the most unsavoury, dangerous people on our planet.

Britain no longer has the domestic ability to make wind turbines - we have conceded that to Germany and are dependent now on Siemens to come to Hull to manufacture turbines for the North Sea. And solar panels have increasingly been coming from China, although new EU anti-dumping tariffs may stem this flow. Meantime, back in Germany, which is like China powering ahead in its renewables revolution, the hallmark of change is widespread individual and community ownership making it a highly democratic form of energy. Interestingly, small scale ownership is being encouraged in China alongside its larger schemes.

With this week's news, Britain may now conceivably lose much of our not large solar manufacturing base. Even our carbon emission reduction target of 15% by 2020 has been specially negotiated to be lower than other major EU economies like Germany (18%), France (23%) and Italy (17%). Only Malta, the Czech Republic and Luxemburg's targets are lower than ours - quite the opposite of the impression you'd get from the likes of UKIP or the Daily Mail. Only the SNP Government in Scotland, where renewable investments and capacity is not far behind that of Germany, offers any real hope for Britain not being left behind in the renewables revolution.

It could be so different - every house could be its own power station, every community could meet its own needs, and the Big Six energy companies would vanish. We would be free to follow a truly ethical foreign policy and Britain could be in contention with the skills, jobs and manufacturing capacity needed to lead the way in clean energy. And we could make a big contribution in reality and example in stopping the world from continuing to release carbon at four times the level needed to stop runaway global warming.

A world leader, for all the right reasons.

In Praise of Windpower

2012 - the wettest summer in Britain in 30 years; droughts across America, the worst in 80 years, begin to push food prices up across the planet as crops fail - just as last year they did in the Russian grain belt; wild fires torch Spain, the worst in decades; floods engulf the Philippines and China, the worst in decades; while the entire Greenland ice-shelf thaws simultaneously for the first time in thousands of years, and Arctic ice melts at a rate which results in warming equivalent to a doubling of human-created carbon emissions.

Still think it's just a coincidence that global warming just happens to be taking place alongside humanity's continued release of record amounts of carbon gases into the atmosphere? Never heard of cause and effect?

The Earth's temperature is delicately balanced in a range that permits life to exist on its thin crust. Our planet lies in the so-called "Goldilocks zone" as astronomers call the narrow band out from a star where it is neither too hot, like Venus, nor too cold, like Jupiter, for life as we know it to exist. The Earth is particularly blessed by the development of our biosphere into a world with contrasting climates which enhance the overall temperate nature of our planet - keeping it just cool enough for plants to grow and people to flourish.

Key to this is the albedo effect - this is the rate at which the Earth reflects light (and heat) back from the Sun out into space. Without it, the planet would burn, as would anything on it. Albedo is strongest on white and other light surfaces, whereas on dark surfaces it is low to non-existent, causing heat and energy to be absorbed by the recipient material.

Traditionally, Arctic and Siberian ice sheets and snow have played a major role in reflecting heat back off the planet - while just 4% of sun light hitting an asphalt road is reflected back, with snow the rate is between 80% and 90% and ocean ice is around 70%. As global warming caused by human activities heats the planet and these ice sheets melt, the overall albedo of the Earth has started to decline, creating an upwards spiral. As dark water replaces white ice, even more heat is absorbed, leading to more extreme weather patterns such as more typhoons and storms. The feedback loop continues - as Siberian permafrost melts, methane gases twenty times more warming than carbon are released; more ice melts; albedo declines more, and more. Currently, the Albedo effect provides the Earth with an average temperature of around 15C. As ice cover reduces, this is rising, and if, in the extreme, all the ice and snow on the planet was to liquefy, this would rise to an average of 27C: far above the level at which most forms of current life, including humans, could survive.

We need to act urgently more than ever. We need to see a huge switch from carbon fuels to cleaner alternatives. Yet this week, the British Coalition Government has appointed an Environment Secretary, Owen Paterson, who is both a sceptic of climate change altogether and keen to abolish any and all support to alternative forms of energy - "fracking" for poisonous shale gas and oil is his pet project. He is keen on green fields, it seems, as long as they are on rich people's estates and splattered with the blood of shot pheasants and , in his ideal world, the body parts of foxes torn apart by hounds. That, ultimately, his green and pleasant land is going to be parched and turned dry brown by rising global temperatures, seems of little concern to him. Like most Tories and capitalists, he can't focus much beyond next year's dividends sheets.

A poet, Derenz, has written on the beauty of wind power, one of several forms of alternative energy which is clean and limitless, and the bizarre hypocrisy of those who oppose them in the name of a nature in imminent peril from carbon emissions. This is the closing verse:

Wind-flowers,
towers, remain
unplanted as the planet
heats, while the booted
arrive in cars of steel,
to tramp hill to hill,
heel to heel,
across the shrinking peat.

Nuclear Nonsense - do you trust them?

The British Government is extending the life of our existing 16 nuclear reactors. This in part helps them fudge the divisions within the Coalition on nuclear as a component of future energy production; but the prospect of even older reactors continuing to produce more and more radioactive waste is concerning. All the more so when you consider the repeated assurances by Government Ministers and industry "experts" that the systems used are safe - and yet, time and again, everything from technical failure to human error raises new concerns.

We have the potential to develop the most powerful offshore wind and wave energy production in Europe; this would be clean, risk-free in terms of waste and safety. Yet one of the first acts of the Coalition Government was to drop plans for manufacturing and installing offshore wind farms in the North Sea that would have created thousands of jobs, made Britain a contender in the alternative energy market (where we are far behind the likes of Germany) and given a massive boost to clean energy.

This was done in the name of austerity; but the extension of the life cycles of ageing nuclear power stations means that the Government will find billions of extra pounds to subsidise this inefficient, dirty and dangerous technology. The public support wind farms by a margin of over 2 to 1, contrary to the claims put up by the right wing press - and if the concentration is on offshore, this would be even higher. Wind alone is not the answer - no green campaigners have even claimed that; but it is a vital part of the mix, and one that Britain could readily harness.

Isn't it time we demanded the Government's investment goes there instead of continuing the massive subsidy of nearly £4 billion per year to run and, eventually, decommission nuclear reactors (let alone store and protect the waste for several thousand years)?
