One thing we have learnt this week- oil price

1393663411Yesterday after an OPEC meeting the oil price fell dramatically. Brent crude fell by almost $6/barrel in one day and there is talk of it going as low as $60/barrel.  The latest falls come after around a 30% fall in the oil price since the summer.

What’s with the oil price if we are running out of it?  The latest falls are due to OPEC not agreeing to price cuts, but the fundamental issue is that since the summer the Saudis have been pumping more oil.  This has coincided with what is probably the near peak in US shale oil production which most analysts think will be in decline by 2018.  The question is why are the Saudis doing this when they need much higher oil prices for their economy?  No one seems to know for sure, but the reasons could be the following;

  • Geopolitical – to damage the economies of Russia and Iran and bring them to the negotiating table.  Iran has had lower output for years due to international sanctions and its debatable how much the lower oil price will hurt them.  There is no question about the effects on Russia though.  Around 85% of Russia’s export earnings come from oil and gas, most of this being from the oil, the gas seems to make them very little money.  Whether this is good news is debatable, countries with tanking economies tend to seek foreign diversions and the lower oil price has not stopped continuing intervention in Ukraine so far.
  • Economic.  The global economy is slowing down even the BRIC countries are now facing economic trouble.  This is certainly part of the reason for the fall.
  • The Saudis want to finish off the US shale oil industry.  Whilst the rumours are the US government has persuaded the Saudis to pump more oil, this is one reason being suggested.  Whilst the production price has fallen (supposedly) of shale oil to below $80 or even $70/barrel with sweet light crude being less than $70 as I write this there is every reason to think the shale oil industry will be devastated if this low oil price continues.

This brings me to a couple of my own ideas.

  • The Saudis want to finish off electric cars.  In the paper yesterday there was a report saying sales of electric cars were really taking off.  This is despite range anxiety and still very high costs of the cars cf. conventional fossil fuel cars.  There are reasons to think over the next year or so the price of batteries will plunge.  If so electric cars will look a lot more viable.  Since most of the world’s oil is used for transport this is a huge threat to Saudi oil hegemony.
  • Next year there are the critical climate change talks in Paris.  Cheap conventional energy has to be a threat to a climate agreement since it makes the alternatives so much more expensive.

None of these ideas are mutually exclusive.  As we have blogged on here recently there are good reasons to think the oil price decline maybe temporary.  It depends on how long Saudi Arabia can hold its nerve.  Once they agree cuts the oil price will soar again.  As a last point despite a large fall in the future traded price of natural gas over the last year or so there have been no cuts in energy prices here.  Funny that.

Peak oil is not dead but only resting…

Christian Climate change deniers

carbon cycle infographicIt was bound to happen, with only a year to go to the vital Paris climate change talks Christian Climate change deniers are on the march.  The Cornwall alliance (the name sounds so cuddly) have issued a ten point manifesto to protect the poor from a harmful climate change treaty.

Taking each point in turn…

1) Point 1 suggests whilst we can damage creation, God’s made it so wonderfully that it will self correct so we don’t need to worry.  Where to start…  The first thing to say is that God has made a wonderful world and to a degree this point is true.  Out this morning I saw a wonderful maple leaf and praised God for it.  Later this leaf will rot and help maintain the soil, this is self correction.  The earth’s climate will self correct as Chris Rapley made plain in his article in the Observer on Sunday, but just not in a timescale that’s any use to humans.  In the meanwhile we will have to suffer the consequences.

2) The next point these Christian Climate change deniers make is that “Earth’s temperature naturally warms and cools cyclically throughout time, and warmer periods are typically more conducive to human thriving than colder periods.”  Again sort of true, but not helpful.  In researching our next book, its clear that even the natural temperature changes have been highly disruptive to humans especially for agriculture (see below).  The kind of changes scientists forecast are out-with anything humans have experienced. See this.

3) Point 3, like most deniers this lot cannot suggest climate change is not real, just pore cold water on the whole thing and its not going to be that bad.  Maybe, but if we are wrong it will be too late…

4) Again sort of true again, but in my view not helpful.  The point is since the industrial revolution its us that are changing the climate.  At the moment we are having the largest effect.  In addition el nino and sunspots maybe masking greater change…

5) Similar to the last point above and scientifically illiterate.

6) Are yes the old CO2 is fertilizer argument… See this post I did here.  To summarise its thought that increased CO2 in the tropics will not have any positive effect on plant growth, whereas in temperate regions it may do.  This is because many tropical plants use an additional pathway called the C4 pathway.  This makes them as efficient as they can be at fixing CO2.  However the biggest effects will be weather changes on plant growth, these could be beneficial or disastrous depending on when and where you are.

7) Point 7 suggests they might like to read our book, in recent years certainly in Europe with natural gas and globally with oil fossil fuel energy has become increasingly expensive and insecure.  There is reason to believe the current price falls will not last.  Fossil fuels and uranium are finite we need to get off them for other reasons other than climate..

8) I’m tempted to say we don’t know since we have not tried,  all the science from 97% of climate scientists suggests getting off fossil fuels will stop future increases in temperature.

9)/10) It curious isn’t it that China, India and a growing number of developing countries are switching wholeheartedly to renewable energy.  It looks as though solar electricity will be cheaper than gas even in the UK soon.

The problem with this bunch of Christian Climate change deniers is they have taken things that are true and distorted them out of proportion.   The real fact is that far from protecting the poor climate change will harm them hardest and first.  A fact that the Christian development agency I support recognises.  Andy is interviewed by Valerie Comer on why Christians are not interested in the environment here.

One thing we have learnt this week -more doubts over Hinkley C

More doubts over Hinkley C have been raised this week after the nuclear power manufacturer Areva that has a stake in the prospective plant issued a profit warning.  Why this story which has almost passed by almost unnoticed this week is raising alarm bells is that Areva’s problems are caused by the construction problems they have had building the reactor in Olkiluoto Finland as well as the two reactors they are building in France which are running over cost and behind time.

Its difficult to find unbiased reports on the Olkiluoto project but the project was signed in 2003, construction started in 2005.  Very like the UK and Hinkley C there was supposedly no state aid although the loans were very cheap and subsidised.  A consortium of private Finnish companies (TVO) ordered the reactor.  From then on everything that can go wrong has done.  Part of the problem for Areva was it promised in its contract to build it for a fixed cost, after huge cost overruns its tried to get out of this and both TVO and Areva have sued one another. Even Areva’s website shows the delays (according to it the reactor should have been operational in 2012!).

The latest is that operation is expected to start in 2018 and the reactor costs have soared by at least 3 fold.  One hidden cost for TVO is they will need to buy power in the meanwhile from somewhere else.  This has to raise more doubts over Hinkley C, since Areva’s three projects have gone pear shaped.  The warning signs have been evident in the UK.  I saw Vincent de Rivaz– CEO of EDF Energy say on Channel 4 news in 2005, they wanted no subsidy.  Then a few months later on the same show he said that they wanted £1Billion, I believe to clear the ground at the site (seemed a lot to me).  After much delay we understand they want a guaranteed price of 9.5p + RPI for 35 years and now finally we understand that the cost of the project may have risen by £10Billion.  Its hard not to see the government being asked to bail this out at some point down the line.

In the interest of balance our view that nuclear is not the answer to climate change or peak oil has not gone unchallenged (see our books Amazon page) and our responses here.  The whole business of Hinkley C is especially puzzling when the UK energy secretary says that solar will be the cheapest energy source.  Its up to those who disagree with the above to explain themselves.

Zero growth- are we in a new era?

economics wordleAre we entering a new era of zero growth with another global crash and slump?  Yesterday David Cameron just back from the G20 summit warned of another global crash.  Whilst this maybe domestic politicking there is some evidence to suggest he could be right.  China has slowed down,  Brazil has slowed down, the Euro zone just avoided recession, Japan is in one and there is political and economic uncertainty with Russia’s activities in the Ukraine and with Ebola.  Add into this mix going forward energy insecurity and climate change and I have been wondering once again whether conventional economic growth is over and we should get used to zero growth?  There is a built in assumption in the global economic system that endless growth is possible. We wrote about this in our book.

…conventional economics with its expectation of continual economic growth seems to ignore the fact that humanity exists within a closed, finite system. Our way of life, our
expectations, our economic models are built on the presumption that the resources humanity draws on (such as energy) are unlimited – and that business as usual can continue ad infinitum“.

Many of us think its not possible (to me this seems quite logical). We briefly examined the work of Herman Daly the Christian economist who is one of the few to have faced up to what a zero growth economy would look like.  The answer is by design it would look very different, but it seems we are slipping into an era of zero growth not by design, but by accident.

One thing we have learnt this week- IEA WEO more pessimistic

The annual IEA WEO (International Energy Agency World Energy Outlook) report is out.  This is a big deal in the energy world and comes at a very interesting time.  Today the oil price has hit a four year low.  Some people think we are entering a new era of new oil prices due to unconventional oil.  Despite all this the IEA WEO 2014 report is far more pessimistic than you might think.

The IEA is the rich world’s energy watchdog, it was formed after the first oil shock in 1973 to advise Western Governments on energy matters.   It has had a variable relationship with the idea of peak oil a good summary of which can be seen here.  In 2005 the US government Hirsch report came out, this was the first report to take peak oil seriously and raised its profile as an idea more than it had been for 30 years. In the IEA WEO 2005 report though everything was rosy and it wasn’t really until the IEA WEO 2010 report that peak oil got a mention, of course it was not called that.  The exact phraseology was far more subtle, we would not want to panic everyone;

Crude oil output reaches an undulating plateau of around 68-69 mb/d by 2020, but never regains its all-time peak of 70 mb/d reached in 2006, while production of natural gas liquids (NGLs) and unconventional oil grows strongly.

By 2012 everything in the oil garden was once again rosy.  This IEA WEO report made big news, unconventional oil would fill the gap and peak oil was dead (our first ever post!).

The IEA WEO 2014 is again despite a background of falling oil prices far more pessimistic.

  • The report has its usual warnings on climate change (the IEA are not climate sceptics) and on phasing out fossil fuel subsidies (worldwide these are huge).  It remains to be seen if anyone takes nay notice of this.  I’m praying for the big meeting in Paris next year but the news from the Asian summit over the last few days has been encouraging.
  • The IEA WEO 2014 report sees an energy system under “stress”.  They think that low oil prices will lead to slump in exploration and new production and therefore a supply crunch.  They think energy demand will climb another 37% over the next 25 years.  This will be very difficult probably impossible for our fossil fuel supplies to meet (in my view).
  • Whilst everyone rubbished peak oil in 2012 there were two things they missed in the IEA WEO report from that year.  The first was that unconventional oil would not last long in the US and the second that we would still be very dependent on the middle East.  Both these points are shown in the following graph from this years report.

oil supply projections from IEA 2014

  • US shale oil will go into decline in four years time, we need a another 14mbd of oil and oil equivalent to meet global demand and all that shortfall is mysteriously going to come from the middle east (no I don’t think so either).
  • The IEA think there will be more nuclear but that it will provide a far smaller & of global energy and recognise public concerns over its safety.  A massive 50% of all new energy investment will be in renewables.

This latest IEA WEO report shows peak oil is not dead but at best has been delayed a few years and we still face significant energy supply challenges.  All this will have profound implications for all of us but also for Christians and the church and its a bit surprising that we don’t think about it a bit more.

Peak oil and end times theology

siluetA few weeks ago the film “Left Behind” came out, this and my daily readings set me thinking again about peak oil and end times theology.  As we wrote in our book;

Some churches and Christians, it seems particularly in America, are fixated with the second coming of Jesus and the events that might presage it. Conflicts, political events and groupings of countries are often assessed to see if they could fit with the various prophecies and pictures that the Bible provides.

and

Some of the speculation is informed not so much by biblical scholarship, but by
the best-selling books and films which have woven the supposed events into fictional narratives.

As I read through my daily readings recently on Matthew 24 my mind again turned to peak oil and end times theology. The whole issue of peak oil which will hit us eventually, if it has not started already (see posts to numerous to list on this site) does lend itself to the apocalyptic.  After all the whole of civilisation is heavily dependent on fossil fuels for almost every aspect of daily lives.  We can argue about when this stuff will run out but at the moment civilisation would be very challenged to do without it.  Yet surprisingly most Christians seem blithely unaware of peak oil and its implications and the end times theology seems firmly centred in other aspects of the middle east such as the conflict between Israel and Palestine.

The problem with many of the passages that end times theology is dependent on are that in my view they talk about the present, the future and the return of Jesus all in the same section.  This makes disentangling the meaning challenging.  Our culture thinks about time in a linear manner, people in the past didn’t think that way.  Read the old testament prophets and you see this with the narrative going forwards and backwards as you move through the text.  We can pull out a few conclusions though;

  • People get too obsessed by the whole business looking for signs.  No one knows when it will be Matthew 24v36, don’t believe those who say they do.
  • To me there seems little love in those who are obsessed by this issue, it seems all about revenge and judgement rather than grace.
  • The whole obsession seems to corrode an interest in life here.  There are plenty of problems that we should try to solve here, environmental, social and health wise.  Sure we will not solve them all or build heaven on earth, but if you believe the earth will soon be burned up you are unlikely to try.  There are plenty of verses in scripture which tell us to get stuck in down here building the kingdom, not least the lord’s prayer.  As Martin Luther said “Work as though he will not be coming for a 1000 years.  Be ready as if he should come today.”

Christianity today no less gave the Left Behind movie a terrible review.  For a more intelligent look at the second coming I recommend “The Clowns of God” by Morris West.

One thing we have learnt this week- Irish wind power

the irish flagWith all the talk of the German energy transition are we missing another countries change, that is Irish wind power?  There are now a whole heap of websites where you can look at what’s happening on the grid in real time.  Yesterday looking for something else I found one and was very surprised to see earlier on that day 70% of Ireland’s electricity was from wind power.  By the time I had found it had dropped to a still very impressive 30%.

Ireland rarely gets mentioned in energy terms.  I have read about big battles over offshore gas finds on the West coast and I know Ireland used to get a lot of its electricity from unsustainable peat, but the rise of Irish wind power has crept up on me.  A high voltage DC interconnecter has recently opened to the UK.  This means both countries can iron out excess or shortages of power.  What I don’t know is whether the wind industry in Ireland has a lot of opposition as it has here.

Obviously Ireland being a small windy country will find it easier to its needs from wind than a larger country like the UK or Germany, but its still very impressive.  Well done Ireland.

Harvest festival time

DSC_1732_optIts harvest festival time and as we have covered on this blog before just as food security is becoming more important less and less churches have harvest festivals.  My church has not had a harvest festival this year. This is strange since food and harvest is an integral part of the bible.  For example I noticed this the other day in my daily reading from Jeremiah  31v5.

Again you shall plant vineyards on the mountains of Samaria; the planters shall plant and shall enjoy the fruit.” ESV.

The reasons are most of us are urban unlike in biblical times and we have become divorced from nature.  If a crop fails it means we pay more at the supermarket.  This is of course at the root of both our lack of concern for the environment and lack of action on climate change.  Growing your own I think will be vital in a post oil world.  But in the meanwhile its healthier for you, fun, tastes better, is in many cases cheaper and reduces food miles.

As is traditional at this time of year I will write a brief report on my own harvest festival time, not to boost, but to encourage you to have a go…

In general most things have been less successful than last year, although 2013 had some notable failures.  This year there have been fewer of these but generally yields have been lower. We had a cold spring and another very hot dry July as we did in 2013.

Salads have grown as well as last year, in addition having mysteriously failed to grow any cucumbers (which are very easy to grow inside) this year we had piles.  Tomatoes were less successful than last year (see picture) but we still had a reasonable crop.  This I grew mid sized ones which did well and cherry ones which almost failed to crop.  Unlike last year (due to the heat) I have grown spinach (although there were complaints about the number of slugs in it!).  Coriander has done well although not as well as last year.  All the herbs have done well apart from Lovage which did not survive last winter.

DSC_1717_opt

Root vegetables were mixed.  I grew two lots of Potatoes, the 2nd earlies did OK, the maincrop cropped well but have been ravaged by slugs (due to the mild autumn?).  I had the usual battle with carrot fly with Carrots and Parsnips.  Both survive if treated with a biological control but seem to go into stasis for weeks.  Parsnips look OK but I have not tried them.  The Carrots were attacked again in the autumn due to the mild weather.  I’m going to try building a barrier next year.

Other vegetables have been more successful.  Mangetout, Climbing French and Runner beans have done very well.  I even managed a second modest crop of Mangetout this year which we are still eating.  For the first time for a number of years I have grown a large number of courgettes and my leeks have been much better than last year (and taste great).

Fruit has generally not done as well as last year.  Strawberries were a total right off.  The main apple tree has not produced nearly as much fruit but its been bigger.  I have harvested enough fallers for three gallons of cider which is fermenting as well as lots of stewed apple.  The self fertile Plum has not done as well (like the Apple poor setting due to the cold spring I think), its fruit was also attacked by vast armies of wasps.  Nevertheless I have kilos of fruit sitting in the freezer.  The Gooseberries did fairly well the biological control having eliminated the gooseberry saw fly.  Blackcurrants did well (still no virus) and Raspberries did surprisingly well despite virus.  Last year I bought a Damson and more small apple trees, the Damson died and was replaced for free, all failed to produce any fruit, but are too small.

I still have hardy winter lettuce and and Japanese greens in the ground and lots of artichokes, leeks etc. to dig up.  For me crop failures are not critical but remember for many people still mean life and death.  Happy harvest festival time.

One thing we have learnt this week – solar energy payback

DSCN1669One thing we have learnt this week is that solar energy payback is now much faster than people think.  As we wrote in our book all energy sources have to have an energy investment made before you get an energy return.

Energy scientists use a measure called the Energy Return on Energy Invested (EROEI), which can be applied to any energy source. To obtain energy (from, for example, firewood) some energy has to be expended: in planting and growing the tree, making the tools to cut the tree down, the physical labour involved, and getting the firewood back to where it is used. This is fine when there is a net gain in energy, that is, the fire gives you more heat than all the energy you put into the process. If the firewood produced five times more energy than what had been expended, the net energy gain, or EROEI, would be 5:1. With concentrated forms of energy like oil, the EROEI ratio
can be as high as 100:1, because even with all the effort of drilling, pumping and refining, there is still a colossal payback in terms of the energy recovered.

In actual fact as we go onto say the EROEI has been falling for oil and gas as the easy to extract stuff has been exploited.  Conventional oil and gas give a return ratio of less than 20 x now.  Wind returns vary depending on the study, but are generally better than oil, coal and nuclear.  Solar energy payback has always been thought to be slow reducing its EROEI over its lifetime.  Generally it was thought to be about 4 years.  Of course solar energy payback depends on the location, but this was a conservative figure for Northern Europe and the US.  A couple of climate change scientists have now determined the payback could be as low as 2 years or in the best way of looking at (and new to me) 1000kW of generation per 1kWp of system for systems since 2010.  In other words if my 1Kw system generates 500W a year it will take two years to payback the energy to make it.  In the Southern USA this could be less than a year.   For me personally this means both my old and news systems are now positive energy producers having made that solar energy payback.  The EROEI would now be roughly 12.5 (assuming a system lasts 25 years) perhaps 25:1 or greater in some places.  Incidentally the same authors have looked at wind power and even from the earliest days when turbines were unreliable and blades flew off its been a net energy generator.

The authors did the analysis to work out whether the above renewables were generating enough energy to provide for the production of new renewables without recourse to climate change generating fossil fuels.  They conclude that solar probably has since 2012 and wind energy has always more than compensated for the energy needed to make new turbines.  Two slight cautions.  The original paper is not free and so I do not know whether the solar energy payback includes replacing an inverter over this 25 year period and whether the wind is onshore or offshore or both.  There is also the decline in output from PV systems to be taken into account although this is very low, the oldest PV system in the UK has showed a decline 2.5% over 20 years.  In actual fact PV modules will work well for 40 years and are fully recyclable making the solar energy payback even better than quoted above.

A reply to Owen Patterson

00002_optOwen Patterson was until a recent government reshuffle the UK environment secretary, basically responsible for the non-energy side of the environment (food, farming, national parks, forests, etc) largely in England.  He reputedly was a holder of the post who did not believe in climate change and would not be briefed by his government’s scientists on the issue (something he will not confirm or deny).  I heard him interviewed on the radio two weeks ago after he gave a speech attacking the government (not just on the environment – he does not seem to agree with his party on much).  This is my brief response to this interview (which was all about his environmental attitudes and ideas).  Owen Patterson made four points, in no particular order…

  • Climate change has been slowing down since the 90′s.  This is the sceptics current favourite point.  Interestingly like most sceptics in Europe Owen Patterson does not deny man made climate change, just suggests its not as bad as its made out to be.  I think he does believe in it, he’s too intelligent not to.  Anyway what he said is not really true.  Land temperatures have slowed down but most of the worlds surface is water.  That is where the energy is mostly going.  Also El Nino and sunspot activity have depressed the temperatures on land, expect a bounceback at some point in the future.
  • The big problem all these people have is wind energy (hence the photo), the perceived ugliness of wind turbines is what seems to tip them over to climate scepticism . Owen Patterson does not like wind turbines to look at.  This then leads onto saying they are unreliable and don’t work.  This latter point is untrue for the last week UK wind power has beaten nuclear and all records. I personally like wind turbines (as polls suggest in the UK most do- even those who live near them), however I do have increasing concerns about proliferation, really infilling between on-shore wind farms.  There are places I would definitely be unhappy to see them but still think there are plenty of dreary bits of country as well as industrial areas where they can go.  So I do have just a bit of sympathy here Owen Patterson’s views since I don’t want to see them everywhere and think there is an upper limit to the number of turbines on land.  I am however very enthusiastic about off shore wind, which I suspect he is not.  Where I strongly disagree is that the grid will collapse with wind power since we cannot rely on it.  The forecasting is remarkably accurate.  In any case no one is suggesting just using wind power, but a basket of technologies. What we must ensure we have is adequate energy storage and we need a lot more of this fast or we are going to have problems dealing with our excess output.
  • Conservation.  Owen Patterson made a number of good points about energy conservation and its importance.  The only example he gave was about smart fridges and freezers.  An interesting one and a good idea although non of these devices are as far as I know on the market.  There is good news on this Mr Patterson.  Peak electricity demand in the UK is falling.  This is partly due to the EU (something Owen Patterson does not like), which is perhaps why he did not mention energy efficient bulbs and the EU mandated phaseout.  With 25% of domestic energy being used for lighting this is one reason why energy demand is falling.  Another is more efficient white goods (another EU directive).  Another reason is a massive amount of micro-generation.
  • The last and most controversial bit of the interview was about energy security.  Since renewables don’t work (I beg to differ), we must embrace nuclear and fracking.  His nuclear power idea was to use lots? of small reactors.  These small reactors have been talked about for decades but none have ever been built.  There was even talk of making them portable and even using them in disaster relief.  The problem with talking about fracking, nuclear and energy security in the same sentence is that its a complete contradiction in terms.  It would take at least a decade to get either going in the UK or Europe to make any serious contribution to this problem, too late.  In addition Mr Patterson wanted the nuclear to do combined heat and power.  This must mean (although he did not say so) the nuclear plants being in urban areas.  In these days of terrorism and IS this is a complete nightmare.  Can you imagine the opposition? Also would you want your hot water even indirectly from a reactor, (no me neither). On fracking it would make the opposition to wind look minor.  When I was researching this for our book I was stunned just how many wells had to be drilled.  Its hundreds and hundreds per field.  That’s lorries, water, waste and large areas of concrete on a vast scale.  Its not going to happen and even if it did even Lord Browne (ex BP now a fracker) says it will not lower gas prices.

I just wish politicians would think about the practicalities of some of their solutions before they opened their mouths….
