What does ‘fracking’ mean?
The other day I read a Guardian article on line in which a fracking protagonist stated that fracking has been used for years in UK land-based oil wells when water is pumped into the well to force oil out. It’s true that that practice has been common in the oil industry for many years, particularly in wells which have passed their peak production. But that has never been called ‘fracking’ before, that I am aware of.
I listened to another protagonist on the Today programme, who said that fracking was an integral part of drilling for geothermal energy, although geothermal drilling is an entirely different process, which recycles the water. In all the time since I first assisted in a geothermal test drill in the Rosemanowes Quarry in Cornwall in the early ‘80s, I have never heard the word ‘fracking’ in this context.
I have a sense that the ‘fracking’ enthusiasts are subtly widening the meaning of the word, to include processes which are, or have been, in common use without controversy, thereby gaining a kind of 'borrowed respectability'. It’s a neat trick!
So when I read the Telegraph article by David Cameron, I admit to looking at it with an analytical eye, because, like Tony Blair, he is good with words!
It has to be said that although the protests at Balcombe have turned into a national event, many of those protesters are there because they perceive a potential effect on their own lives from copious heavy road transport and the likely effect on the water supply, both through over use and through pollution, both of which have been experienced in the USA. These are entirely reasonable and valid motives for the protests, but in global terms they are probably amongst the less important reasons for objecting.
There are many lessons to be learned from the American experience, but it seems that our political leaders are surrounded by people who tell them what they want to hear, rather than the facts. On the other hand it has been suggested to me that the present Government attitude is simply designed to fend off UKIP and keep the Tory Right in check, and that after the next election many obstacles to planning permission may be discovered! But they are politicians – how can we possibly know what they really think!
In his article, Mr Cameron said, ‘If we don’t back this technology, we will miss a massive opportunity to help families with their bills and make our country more competitive. Without it, we could lose ground in the tough global race.’
It is difficult to understand exactly what he means, aside from the bit about bills. How will it make us more competitive? How will it affect our position in the ‘tough global race’? As for that bit about bills, that probably won't happen, because fracking is a very expensive process, and importing gas from Norway and Qatar is actually likely to be cheaper, even with George Osborne's generous tax concessions.
As Mr Cameron says, ’Just look at the United States: they’ve got more than 10,000 fracking wells opening up each year and their gas prices are three-and-a-half times lower than here’.
10,000 wells a year! Imagine that!
Well, exactly! Mr Cameron, this is how it works:
The banks, always on the lookout for an opportunity, have smothered the industry in the US with loans, secured against the assets of the companies, who are making hay while the sun shines. But a shale gas well produces about 80% of its capacity in the first two years. So in order to maintain the flow (and it is the flow rate which is important) they have to keep drilling new wells as the old ones die (hence Mr Cameron’s 10,000). And as we have said, drilling wells is expensive. So why are gas prices in the US so low? Because they have been over producing, running fast to try to keep up with themselves! Then they have been exporting gas to countries like ours where gas prices are higher than at home, to try and recoup some of that money. In 2012, the expenditure on shale gas drilling in the United States was $42 billion. But receipts from sales of that gas were less than that by about $10 billion. As our American cousins would say, ‘Do the math!’ To me (but I am no expert) it has the smell of subprime about it!
Meanwhile, in the US the green-washers have been triumphantly extolling their reduction in CO2 emissions, forgetting that the coal which they haven’t been using has been exported to someone else, whose emissions have gone up.
Mr Cameron is undoubtedly right in claiming that a thriving shale-gas industry in this country would support plenty of jobs (although not for a while yet), but not nearly as many as would be supported by a thriving renewable and energy conservation industry.
Mr Cameron claims that a well-regulated shale-gas industry would be safe, by which I presume he means no water pollution, no loss of domestic water supplies and no leakage of methane into the atmosphere. Good luck with that! But I can afford to take an objective view because there will be no fracking where I live (unless it is for geothermal energy).
My objections to this industry are twofold. The first is that it merely prolongs our dependency on fossil fuel, with all that that implies for the decarbonisation of our energy supply. The second is that for a relatively short term benefit it is far, far too expensive (and will do nothing to reduce our energy bills).
I do have a third objection, which is more general and relates to the whole approach to Government by this coalition. In his article, Mr Cameron once more suggests that we are all in this together. He wants us all to share the benefits. He says, ‘Local people will not be cut out and ignored’.
But that is just what is happening at Balcombe.

Irish Water Supply Crisis (and thoughts arising!)
The weather hasn’t been great these past couple of weeks. Travel has been disrupted, on the roads, the railways and in the air. Northern Ireland has had significant problems with water supplies, with many people being without supply for several days. Urgent calls for blood donors went out to anticipate increased demand. Petrol stations ran out of fuel.
The priority amongst those who administer these facilities has been to get back to normal as soon as possible. The priority amongst everyone else seems to have been to find someone to blame, and to scapegoat them. The result of all this blame is to take the attention of the top managers and officials away from problem solving, in order to provide a public apology, a resignation or a decision not to take a bonus.
Heads must roll!
Small consideration is given to the fact that this level of snow and freezing temperatures at this time of the year is (or has been up until now) a freak occurrence. No manager, administrator or minister worth his salt is going to spend a fortune preparing for freak conditions, thereby risking the wrath of the budget keepers, the accountants and the voters. If those conditions can be shown, later, to fall outside the definition of ‘freak’, and nearer to the definition of ‘normal’, that is the time to spend the money.
What we have heard, and will hear again, is that well worn phrase, ‘Lessons will be learned.’ My question would be, ‘Which lessons?’
We can safely assume that in Northern Ireland, decades of troubled times, under all shades of Westminster government, has resulted in a considerable under-spend on water infrastructure. It’s pretty pointless then, to look for a token scapegoat.
The problems at our airports arise from the assumption that freak conditions are just that, and are unlikely to occur. To compare the situation at Heathrow with that at better equipped continental airports is invidious – they have always had more snow and lower temperatures than we have, and are more used to it; furthermore, they have not been without their weather related problems. Recent freak conditions in the US have caused similar disruptions, and they, too, are more used to severe winter conditions than we are.
The complaints regarding road travel seem to relate to a lack of communication, and the habit of distressed drivers of blocking the hard shoulder.
Much of our difficulties, and all our complaints, arise from an expectation that someone else should be looking after us. The workings of State and Big Business have contrived, over the years, to deprive us of the ability to fend for ourselves, to prepare for extreme conditions as a matter of course, and to ‘get on with it’ at times of stress.
The people in Ireland who are without water are certainly in a very difficult situation, and don’t need reminding of the circumstances in third world countries which require women and young children to walk 10 or 15 km a day to collect the water supply for the whole family, including the sick and elderly within their communities. The distressed road users, many of whom, despite the forecasts, set out on their journeys completely unprepared, won’t give a thought to the millions of people who aren’t able to afford a bicycle, never mind a car. The stranded Christmas holidaymakers feeling miserable in airport terminals are unlikely to work out what percentage of the world’s population have never left their village (or refugee camp), let alone their country.
No, I fear that the important lessons won’t be learned.
In this country we’re lucky – we are not generally short of water, as long as we are sensible. Irrigation of crops is not as prevalent as it is, for example, in North America: there, without irrigation, food production would decline to an unsustainable level, and yet constant irrigation degrades the soil, necessitating increased use of fossil-gas based fertilisers. At the same time, a growing city-based population is taking an increasing proportion of the available water supply: availability of clean water per capita is decreasing as water tables drop and replenishment can’t keep up with demand. Many parts of the world depend on grain exports from the US; and yet, as it takes 1000 tons of water to produce a ton of grain, there will come a time not too many years hence, when the US will no longer be able to export grain – and the irony is that a proportion of their crop will go to the production of bio fuel.
The most water-hungry grain crop is rice. In North Korea, where a majority of the population is undernourished, there is no longer sufficient fuel to power the irrigation systems upon which their staple crop, rice, depends. To make matters worse, in winter they can no longer heat their hospitals, let alone their homes. They don’t have fuel for their farm machinery, so farmers have to do the work manually – but being seriously undernourished, and living in cold accommodation, the labour is very much less than efficient, leading to increasing food shortage and malnutrition. Ultimately, complete societal breakdown is inevitable without huge help from outside.
In a large proportion of irrigated land in Northern China, the water tables are dropping by a meter a year – rivers and rainfall just can’t keep up with demand. In India, two thirds of the Punjab is losing its water tables at the rate of 20 centimetres a year.
Although there was some controversy over a misguided claim by the IPCC regarding how soon the Himalayan glaciers would disappear, that should not blind us to the established fact that these glaciers are receding at a significant rate (as they are in other parts of the world including Europe). Another fact is that a third of the world’s population is dependent on those glaciers for clean water. Already some of the world’s great rivers are reduced to a trickle, or dry up completely, when the demands of agriculture are at peak – and the periods when this happens are getting longer each year.
So what lessons should our politicians, managers and administrators be learning?
First, it is now clear that current agricultural practices are unsustainable (even without the threat of peak oil). This will become increasingly obvious as fossil-based fuel and fertiliser, and thence food, become more and more expensive. A partial solution to this is for agriculture to become more community based, and organic, with a loosening or abolition of the regulatory constraints which are placed on such things as community composting. This solution might involve some incentive to larger land-owners to allow some of their land to be put to community use (without charge). Small organic community based schemes have been shown elsewhere (Cuba for example) to be several times more productive than standard agricultural practice. As the size of a farmed area increases, the productivity per square meter reduces – so small community based units are the optimum for yield, as well as providing local employment, helping communities to enhance self reliance and resilience.
Second, all farming must become less dependent on oil and oil based products very quickly. Instead of cutting budgets on research, more funds should be provided to research and revitalise new farming methods. There are ways of growing crops which take up far less space than current systems, for example, and these should be investigated and perfected as quickly as possible. Lack of oil is not synonymous with ‘back to the stone age’. Properly researched modern organic methods have the ability to increase not only production, but more importantly, nutritional value.
Thirdly, the present rather tired efforts to enhance the value of ‘community’ should be doubled or trebled. This Government is making a few of the right noises in this direction but their actions are working against their sentiments. The more that a local community is stimulated, the more local work becomes available, the more money is generated locally. There was a time when light industry could be found in village high streets, whereas now it is shunted out to industrial ‘parks’, drawing people away from their communities, and engendering a mindset which embraces the long commute, the supermarket, the ‘dormitory town’ and the school with 1500 pupils which produces students who are outside their own communities right from the start.
Fourthly, politicians should be helping to educate the electorate to the fact that life cannot continue as it is. Our lifestyles are going to change whether we like it or not, but at present the Government is doing absolutely nothing to educate us for this. Major changes will occur and our leaders and most people in the ‘developed’ world are walking towards those changes with our eyes shut! The later we leave our preparations the harder it will be to live with those changes and the more chaotic and destructive will be the outcome.
The water crisis in Ireland leads me to wonder, with all the rigorous, so-called environmentally friendly building regulations, why new buildings are not required to capture rainwater for use, at least, in toilets and kitchen sinks. There is no reason why we should feel entitled to use good drinking water for anything other than drinking and cooking.
While we are whining at the Government because they aren’t keeping our roads clear or our trains running, some small island nations are already suffering deeply as a result of rising sea levels. Some African countries are suffering prolonged drought and loss of crops. Others devote their agricultural resources to producing crops for export instead of feeding themselves, mostly through the ‘good’ offices of the IMF and the WTO.
Unless real action is taken to change the way we live, we will soon be whining about failure of road, rail and air travel through lack of economically viable fuel supplies, and while our main sources of groceries (the supermarkets) only keep sufficient stocks to last less than a week without replenishment, we should certainly start to learn how to keep a sensibly stocked store cupboard. Globally we are heading towards shortage of oil, shortage of water and a spiralling global temperature.
The lesson which should be learned by the politicians is not when or how to apologise. It is that there are a number of potential crises up ahead. If these materialise and find us unprepared, it won’t be the odd minister who will have to resign! Meanwhile, those of us who can should incorporate our preparation for the future into our everyday lives, a bit at a time, until it becomes second nature.
The priority amongst those who administer these facilities has been to get back to normal as soon as possible. The priority amongst everyone else seems to have been to find someone to blame, and to scapegoat them.

Compulsory Water Metering
A letter was published in our local paper, the West Briton, this week, expressing horror at the thought of compulsory water metering. This was my reply!
"I was really interested to read the letter from Miss Trewin regarding water metering, particularly the paragraph in which she states that ‘Any kind of compulsory action undermines democracy and is an invasion of the peoples’ democratic rights’. After all, the basis of democracy is the law and its creation and enforcement!
To follow that line of thought through to its logical conclusion, I guess Miss Trewin resents the fact that electricity and gas supplies also have to be metered! Perhaps we should instead be subjected to an inflated standing electricity or gas charge based on house size and location as is the case with unmetered water! The infrastructure associated with water supply is significant, and expensive to maintain (as with electricity and gas), and I cannot think of a reason to treat water as a special case!
More seriously, I am a supporter of Green policies and principles, specifically the principle of conserving our resources where possible. Having used an unmetered supply of water for many years, I came to realise that a more fair and honest approach would be to have a meter installed, so that I paid for what I used. The value from my point of view would be that I would be able to monitor my own water use, and avoid wasting this precious resource. As it turned out, the meter has had the effect of reducing my water bill by more than 50%.
Miss Trewin naively believes that ‘it is logical people will only use the amount of water needed...’ – I have to say that her faith in the human race’s ability to behave in a logical way is different from mine! The fact is that if volume of water used is reflected in the water bill, people will be more careful with its use, as they are with electricity. Additionally, it would enable anyone to judge whether they are being charged fairly or not.
We in Cornwall have probably the highest water charges in the country, but that is mainly due to the burden of catering for the tourists who visit, whether through beach cleaning or sewage treatment. Whether that is fair or not is a question for politicians, and I don’t think it is at the top of their current ‘to-do’ list!
In this economically challenged world, I take the view that we should all pay a fair rate for all our services, and compulsory water metering would allow us to do that. Miss Trewin wonders who would benefit – I would suggest that in the end, the whole population would.
