It fair to say I’ve had one of my best food growing years ever.  I have been consuming local food for months!  Its easier to list the failures rather than the successes.  The failures (all again) are Cucumbers (grown inside), Butternut squash and Courgettes , also spinach and Mizuna.  Fantastic crops of French and Runner beans, Lettuce, Potatoes, Parsnips, Mangetout, Carrots, Coriander and Tomatoes.  Leeks, peppers and Broad Beans are reasonable.

On the fruit front; Plums, cooking Apples (now being made into cider) and Blackberries have been fantastic.  Had a few Strawberries (the plants are young), Raspberries (they have virus) and reasonable haul of Blackcurrants.  I even managed to grow one Melon indoors.  My new apple trees produced no fruit and the damson I planted in the spring died (the company that I bought it from are going to replace it for free since it was defective).

Last year food growing was far harder and the consequent harvest was far lower.  The reason was simple the weather.  I have never seen so much rain.  This year was the opposite, we had a drought with almost record temperatures.  As we wrote about in “No oil in the lamp”,  food is going to be a real issue as far as peak oil in concerned.  We are already in the foot hills of this with soaring food prices over the last decade or so.  We concluded

The alternative to this is to work towards a more sustainable, resilient global food system. This would mean more food being produced and consumed locally rather than being transported long distances.

Part of this is down to us.  I only have a small amount of land but am able to grow an amazing diversity of produce.  The elephant in the room is climate change.  Plants need a benign climate with few extremes of weather.  If all summers are like 2012 we are in trouble.  It shows that mitigating against climate change is preferable to adaptation.

So as we approach harvest festival (in the northern hemisphere), thank God for it, appreciate good food; but don’t get complacent and see if you can grow something, even on a windowsill.

The Earth is the Lord’s and all that is in it… ‘He makes grass grow for the cattle, and plants for man to cultivate – bringing forth food from the earth: wine that gladdens the heat of man, oil to make his face shine, and bread that sustains his heart.’ Psalm 104, 14-15

One thing we have learnt this week – will the lights go out?

Autumn the season of mellow fruitfulness, when energy companies raise prices and also the time when people increasingly talk about the lights going out.virburnum on the change_opt Will the lights go out in the near future?

The opening paragraph in our book is not looking so unlikely now.

The modern world is not perfect, but if you were born in a developed country sometime in the last sixty years, it is likely that you have experienced a rising standard of living, with increasing comfort and convenience. Yet we only need to look back a few  generations to see how much has changed, and how much we take for granted. We flick a switch, assuming that electricity will be there to light up the bulb. We expect to be able to travel long distances quickly, in comfort and at reasonable cost. We think nothing of sitting down to a meal whose ingredients have been transported across the globe to our table. These things and many more besides have become basic expectations for most in the developed world – and as Christians living within a modern, developed country we share them. While we may bow our heads and give thanks for God’s  provision at the start of a meal, in most other ways we take the conveniences of modern life for granted.

As the UK does seem to be entering an energy crisis with the UK government looking to China to fund new nuclear power stations and energy prices soaring, the Royal Academy of Engineering (RAE) has released a report warning that the biggest risk of the lights going out is next winter.  The reasons for this are well rehearsed on this blog.  Coal and oil plants are closing due to an EU directive and gas is too expensive so the the generating companies are reluctant to use it, so are closing them as well.

What to do?  The government is making changes to the electricity market.  The RAE recommend that the government sorts this out as soon as possible.  In addition that it sets a long term minimum carbon price, not just three years ahead, has a discussion with the public about the price of de-carbonisation and has holistic approach to energy strategy.  This latter point emphasises that as we switch to electricity for heat and transport demand for electricity will rise and this need to be taken into account.

I would add we need to encourage energy conservation and micro-generation (neither mentioned in the report).  As a final point readers such as in the USA should not be complacent, it was not so long ago we were energy independent.  Buy our book and find out more.

Forecasting the Energy scene to 2030 and beyond

I read a blog post recently from Bloomberg New Energy Finance forecasting the energy scene to 2030 and beyond.  As we wrote in “No oil in the lamp”;

It is important to state that predicting the future can be a mug’s
game. It’s been said that history is a record of the unexpected. A
detailed prediction can become a hostage to fortune as events veer
off in an unexpected direction. In the area of peak oil, unfortunately
there have been many times when specific forecasts about the timing
and impacts of energy depletion have turned out to be just plain
wrong.”

The blog looked at a number of different areas of a number of energy forecasts and I will summarise them further with some comments of my own.

Carbon emissions

Worryingly almost all the forecasts saw carbon emissions rising.  The IEA (2012 World Energy Outlook) think that annual global emissions will increase from  the equivalent of 30.2bn tonnes of CO2 2010, to 37bn tonnes in 2035.  Exxon (didn’t think they believed in climate change?) in its “Outlook for Energy to 2040” sees a peak of 37 bn tonnes around the same time with a very modest fall by 2040.  BP is most pessimistic seeing no apparent fall by 2030.  The science tells us that emissions have to peak long before 2030, by 2020 in fact.  So this is worrying, however as this blog has said recently there are some grounds for hope with the USA cutting its emissions drastically and China’s growth rate in emissions falling back sharply.  Lets hope this forecast is wrong.

Energy intensity

All see energy intensity improvements.  Both Exxon and the IEA see energy growth being 1-1.2% a year and BP higher at 1.7% (which explains the higher emissions above).  All three forecasts are optimistic on this score since the rate of energy demand has been growing at 2.3% historically.  I would add this latter figure cannot continue indefinitely so something has to give.  There is no indication any of this takes account of EROEI which is declining for all conventional fuels.

Electricity production

The estimates of electricity production are interesting and not something I have come across before.  The range is from 34,000TWh (Bloomberg themselves) to 36,637TWh although the dates at which these will be reached vary from 2030-2040.  Last year global electricity production was 22504TWh (BP Statistical review of world energy), interestingly in the light of the previous paragraph this was up 1.8% on 2011.  No details in the blog are given as to what this very large increase in electricity demand is due to.  As we have outlined in our book the whole economy will have to be electrified.  All road and rail transport as well as heating.  This (depending on the practicality of some of it, such as electric cars) will in theory lead to a very high increase in demand.  A 50% global increase could be due to just more conventional demand such as mobile phone charging and air con units.  In fact calculating both a 1% and 1.8% increase year on year to 2040 gets roughly to the projected figures indicating little if any substitution by electricity for other fuels.  If substitution is added on top then this then electricity demand is going to be much higher.  Some estimates are given in “No oil in the lamp”.

Production

Where is this electricity to come from?  At the moment hydro has a head start over all other renewables being a mature technology.  But looking at non-hydro renewables the ranges reported are from 11-22% production of all electricity (again from 2030-40).  Solar is 2-5%.  These are up from 4% now for non-hydro renewables and nothing measurable for solar in 2010.

Conventional sources pan out as follows.  All the above see gas up and nuclear and coal down although the exact amounts vary.  But where is all this extra gas demand going to come from?  Gas reserves fell for the first time ever despite all the shale gas that is supposedly around.  Don’t expect cheaper gas which brings us neatly to…

Costs

All see costs of renewables falling although surprise surprise Exxon is most pessimistic on this.  Even they see PV costs falling a further 25% by 2040.  PV costs have risen a bit recently because of the China/EU/US trade war but there is no reason why the long term trend of a fall of a quarter in cost for a doubling in capacity should not continue.  Onshore wind follows a 7% reduction for the same capacity increase.  In practical terms this analysis seems to assume no increase in electricity prices.  It seems likely that electricity prices at least in Europe will increase enough make wind and solar cost competitive as their costs fall.  The costs that Exxon suggest for wind and PV 9 and 12 cents respectively look pretty good.  I reckon you can get PV installed at a cost of 6p/unit in the UK (complicated by low export tariff which lowers your return).  Exxon are clearly thinking about competition with conventional power, but for home systems this is irrelevant since what comes up the garden path is a lot more expensive to start with.

Finally this brings me to Bjorn Lomberg who I saw interviewed recently about climate change and has nothing to do with this Bloomberg blog.  Lomberg believes we need a a lot of extra research before we deploy wind and solar of which he thinks the current technology is both rubbish and too expensive.  His comments are illogical, especially in light of the above.   Firstly, Germany (which he criticised explicitly) as I have blogged about in the past gets very large amounts of its electricity from wind and solar.  This seems unlikely if the technology is rubbish.  Second, cost reductions are driven through largely not through R&D, but deployment as we have seen with both onshore wind and PV.  Lomberg’s comments look like his usual dressed up climate scepticism to me.

One thing we have learnt this week-oil prices still high

Why are oil prices still high?  A few weeks ago I wrote about political tensions in the middle east affecting oil prices.  I wrote in conclusion

However, it seems that the current high oil price is partly due to these geopolitical factors and this will continue.

Over the last few weeks we have seen a rapprochement between the US and Iran with UK and Iran in the early stages of reopening embassies.  At the same time the bombing of Syria has vanished with the chemical weapons destruction agreement and there is the prospect of talks between the Palestinians and Israelis.  There is still trouble in Iraq and Libya but generally the tensions have reduced.  The oil price has not dropped- in fact its on a gentle upwards trend.  So it seems there is little geopolitical element to the high oil price.  This means there must be more geological and demand elements to it.  With the world economy picking up demand will be rising.  We have some missionary friends visiting from India.  Demand for oil is soaring there as people buy cars and scooters. At the same time many analysts think supply is tight.  In the row over rising energy prices in the UK yesterday, one analyst suggested whilst most of the increase up to now had been due to gas prices in the future it would be renewables costs.  This seemed slightly naive with the suggestion that gas prices would move up any more.  With gas prices linked to the oil price this seems unlikely.

Peak oil theology

Peak oil theology. Or rather Peak oil, is there specific theology to it?  This was one of the questions I was asked when I recently went to speak at “Christchurch Morningside”.  My answer is the one we gave in the book.  No.

In our chapter on theology subtitled “Towards a theology of peak oil” we looked at dominion, justice, human wisdom and frailty, Jesus’ teaching, the early church as community and end times prophecy, but none of this theology is specific to peak oil.  We concluded;

While there may be no specific Christian response to peak oil,
there are both specific challenges to our faith and also significant
opportunities. The first challenge is that for many Christians
(particularly but not exclusively Evangelicals) our faith has become
a consumerist pick-and-mix self-help system. Neil’s minister said in
a sermon recently that when he browses Christian TV stations on
the satellite channels, at any one point in time 18 out of 20 are
broadcasting health-and-wealth theology. This heresy will be severely
challenged by the events of the years ahead. There is no record of
Jesus owning anything and there is nothing in the Bible to suggest
that this is what our faith is about. Jesus came to bring salvation,
not material contentment. More than a cursory glance at the
New Testament shows that for many of his followers becoming a
Christian was the start of their problems (for example 2 Corinthians
6:1-10). Jesus himself said he had come not to bring peace but
the sword, something that has been misinterpreted, but clearly
implies that life is not going to be a bed of roses. Peak oil presents
us with an opportunity to clear out the materialistic detritus and
focus on what our faith really means.

Anyone got any different views, or come up with definitive peak oil theology?

One thing we have learnt this week- high energy prices people are struggling

I listened to call “You and Yours” this week on BBC radio 4 which had a debate about energy prices. Its obvious that due to high energy prices people are struggling.  Some of the stories were a mixture of inspiration and toe curling sacrifice.  Their were a heap of people  calling in who claimed not to switch their heating on at all.

One person lived in Cornwall and claimed she did not use heating since it was warmer there.  True it is, but we have had three cold winters which have affected the South West of the UK as much as anywhere else.  This person had a well insulated house and a wood-burner in the centre of it somewhere.  As she said she was lucky living in the country with ready availability to supplies of wood.

Another person’s tale was far more scary and war zone like, involving washing in small amounts of cold water.  Yet another had learnt to have only cold showers.  Yet another had been driven by high energy prices to move into one room during the heating season.  He had everything including a small cooker in there.  In the summer he used the rest of the house.  My parents neighbours church does this.  They cannot afford to heat the church building in winter, so meet in the church hall.

The common thread running through all this debate about high energy prices is heating.  Whilst its possible (at least in theory) to do without heat in the UK its extremely difficult to do without electricity.  There was little mention of conserving electricity on the programme even by the experts, although a couple of people had PV systems and raved about them.  One person had used solar PV and solar hot water to heat an inter-seasonal heat store something we write about in the book and I would have been interested in knowing more about.

The “Green deal “ (again something we write about in “No oil in the lamp”) came up.  Its had an extremely low take-up, part of the problem is ironically that many energy efficiency measures take a very long time to pay for themselves or never do within the life time of the product (such as double glazing).  Energy prices as I wrote last week are both too high and too low, but this is largely not due to renewable policy, but wholesale gas price increases and these look set to continue.

How long does wood take to dry for burning?

How long does wood take to dry for burning?  A long time is the basic answer.  I did a talk based around our book at another church last Sunday and biomass heating was one of the issues that was raised.  We wrote that in a UK context;

Wood can provide energy for heating homes and water. In rural areas,
where firewood can be obtained at a reasonable price, it is already
widely used, and is coming into greater use in other areas as heating
from other sources has risen steeply in cost. Better management
of woodland, planting more trees and diverting useful wood from
landfill will all boost firewood supplies, so that more homes could
use wood for heating; however the numbers will always be limited.

This limited contribution is probably the same for the US.  In other countries such as Canada and the Nordic countries (where the forests are managed in a particularly sustainable way) the situation is very different.  However, at the moment its not that difficult to get hold of wood and often for me this wood is from trees that people are having felled for one reason and another.  I did a bit of research to see how long it would take a piece of wood to dry.  The wood was lime.  The graph below shows the result.

wood drying data

How long does wood take to dry for burning?  Someone at church who has a degree in forestry says an inch a year. My experience is that as long as you split the logs well then it can be dry enough to burn in a matter of months.  Leylandii and Cyprus dry in a matter of 6 weeks if kept out of the rain. Much of the Scots pine I obtained in the spring is now dry.  We have had a very hot summer which helped.  I know this partly by the weight of the wood and partly since I have bought a moisture meter that measures both building materials and logs.  According to this meter anything below 11.9% is dry.  Of course this is the surface moisture reading but it does seem to correlate, recently split wood is much wetter.

Follow these simple guidelines from my learning the hard way and you will not have soot coming out of your flue.

  • Cut the wood or have it cut (speak nicely to a tree surgeon) into as short a length as possible against the grain.
  • Split these pieces using an axe with the grain.  The more you split the logs the more quickly they will dry.  Also the logs have a larger surface area compared to their volume and this helps them burn better.
  • Cover top of log pile, but not its sides to keep the rain off but let air flow around the wood

Enjoy your woodburner!

One thing we have learnt this week-energy price freeze

At the labour party conference this week, Ed Milliband announced an energy price freeze on gas and electricity prices for 20 months.  This will happen if labour win the election whilst legalisation is put through parliament to create a new regulator and break up the big six energy suppliers.  This has energy in the news, as it rarely is and a real debate going. The 4 billion pound question (literally) is, is this a good idea?

The first thing to ask is how have we got there?  The regional electricity and gas boards were privatised by Mrs Thatcher.  Part of British Energy (nuclear) was sold off later.  Essentially we have ended up with six energy suppliers (four being foreign owned – ironically by European state owned energy companies).  There are apparently as many 80 small suppliers, but these have less than 2% of the customers.  The big six have vertically integrated businesses i.e.  they generate the electricity and sell it to customers.  They have a reputation for colluding on prices, making excessive profits and having until recently a huge number of complicated tariffs.  The regulator OFGEM (Office for gas and electricity) is rightly regarded as fairly useless.

After privatisation the price of energy fell but this coincided with the peak in north gas production.  The big six built a lot of gas powered power stations so the price of electricity fell.  The amount the consumer compared to incomes spent on energy also fell in line with this gas production. By the way an excellent background to this can be seen here at “Make Wealth History”.  However, since 2004 as gas production started to fall prices have risen.  In 2004 I was paying 6.8p/unit for electricity (which had not changed for years) and about a penny a unit for gas*.  Now I’m paying 16.4p/unit for electricity and 5.06p/unit for gas.  In 2008 wholesale electricity prices soared as gas prices linked to the record oil price soared.  Most of the price increases in my bills have taken place since then.  In 2011 my gas bill went up by 30%. There have been only modest drops in bills since then which have been more than made up for by subsequent increases.   Right wing commentators try to blame increases on renewables, but the bulk of the price rises are due to the fact that we have to increasingly buy gas on international markets.

Back to our original question.  Is this a good idea?  The first thing is to say as a labour supporter I can see where the party are coming from.  I slightly disagree with “Make wealth history” about the implications of the % of consumer spend being lower than it was 40 years ago.  Energy is both too cheap and too expensive.  To explain, I once went round to one very wealthy family that used to go my church, every light was on in every room (occupied or not) in every house plus a number of coal effect electric fires.  For this family energy was clearly too cheap.  However, every article I read or see on TV about food banks brings the price of energy into the reason why so many families (often working) are struggling with their bills.  It not just the price of energy that has soared but also food as well.  For millions of people the price of energy is too expensive.  Despite this I’m worried.  My concerns about this policy are as follows;

  • The big six will push up prices more in the next two years if they think labour can win.  This will clearly undo the good the policy is meant to do.  There is little the Labour government could do about this except legislate for a price cut?  There is a danger at the end of the 20 month period that prices could increase dramatically, although the idea is to use this period to tighten the regulation when the freeze is over so that price increases are smaller and more in line with costs.
  • Related to this what if there is a big increase in the wholesale gas price over this 20 month period?  Ed Milliband is reported as saying today that the companies would be allowed to increase their prices if this happened.
  • There are all sorts of dire warnings about companies leaving these shores and the lights going out etc. due to this policy.  These can be ignored.  In fact two of the big six have cheekily started offering price freeze deals until 2017 today!  One put their advert thus “Don’t wait for Ed… “.  Just slightly undermining their arguments.  If there are blackouts in this period its because of what’s happening now.  At the moment companies are closing coal fired plant and not investing in enough new capacity.  There is distinct reluctance to build gas storage (two schemes dropped this week) and invest in any new gas powered generation (not a dramatic endorsement of shale gas).  Companies are desperate not to use gas to generate electricity since its too expensive.  Hence a big increase in imported coal from the US and electricity from Europe over the last year.  On-shore wind is getting so much resistance in planning that very little is being built.  OFGEM have already warned that the lights may go out.  However, anything that  creates uncertainty for long term energy investment cannot be welcomed.  This may make the lights more likely to go out after 2017.
  • We need to de-carbonise our economy for both climate and energy security reasons.  How does fit in with a price freeze? Labour say almost half of new energy investment is not from the big six and in any case the present governments guaranteed prices “contracts for difference”  will give certainty on investment decisions.  (This is certainly true of PV which is booming judging by the first six months figures for 2013.)  It seems to me that this would introduce more uncertainty though and hence reduce investment in renewables.
  • What about energy efficiency?  There is only one way to get people to conserve and that is higher prices.  We badly need a huge programme of home insulation etc. At the moment renewables are becoming more and more viable as their prices fall and energy prices rise.  Freezing or lowering prices will make this trend slower.
  • Its missing the point.  The days of cheap energy are behind us permanently.  Governments, consumers, business and energy companies have yet to accept this, much less come up with a solution.  There are a number available but the best way of protecting the poorest is in our view is the introduction of Tradable energy quotas (or TEQ’s). This is described in some detail in our book but in my view this (or something like it) will have to be introduced.
  • This investment uncertainty will be heightened by part of Milliband’s announcement that has been almost completely ignored.  However, this is something I think is essential- that is breaking the big six up.  At the moment all them generate electricity and then sell it to themselves then us (this is less true of gas).  I’m with one of the 80 tiny energy suppliers but their billing is handled by one of the big six, according to this big six supplier via my bill, they only make a 3% profit on their electricity.  However, this ignores the generation profits.  Separating the two sides of their business would introduce competition and transparency and would in my view lead to modest falls in prices (or at least slower increases).  It would also allow new entrants to the market (the other 80) to get their hands on gas and electricity at reasonable rates and grow.

Does this mean there is no need for our book.  By no means.  The energy crisis also involves transport, food and materials.  The price of these is rising and will by unaffected by any price freeze on electricity or gas.  To summarise I can understand the reasoning but think this policy idea is not going achieve what its meant to and is bypassing the issue.  Could be good politics in the short term though…

* gas rates were always more complicated because there were several rates depending on how much you used.

The season of mellow fruitfulness is a good time to think about energy efficiency

blackcurrant leaf

blackcurrant leaf

Autumn is upon us. The season of mellow fruitfulness is a good time to think about energy efficiency as the nights draw in (in the northern hemisphere at least).

Here are some suggestions from our book which contains plenty more.  Please feel free to post any other energy efficiency ideas you might have thought of.

  • “Use energy-efficient lights, and  switch them off when not required. Compact fluorescent bulbs are good, but LED light
    fittings (though a little more expensive to buy) use even less
    electricity.”
  • “Draught-proof doors, windows and the loft hatch (easy to
    forget this last one; stick insulating boards on the (upper) loft
    side of it as well).”
  • “Close curtains or shutters at sunset to retain heat.”
  • “Floors are another area of heat loss. There are various methods
    of insulating floors, such as sticking insulating boards or glass-wool
    insulation up between the floor joists (with netting to hold it up
    in the latter case).”

This Autumn amongst the energy efficiency ideas I’m considering are;

Have another look at my floors, which I have difficulty accessing.  However, I have managed to stick some insulation onto the underside of the hall floor.  I will also try and add a bit more insulation to the loft hatch and buy some more LED light bulbs.  We are expecting more energy price rises so apart from stewardship of our planet this makes economic sense too.

One thing we have learnt this week-nuclear power

The UK party conference season is upon us and the first lot up are the liberal democrats, who have for the first time endorsed nuclear power. Albeit in a “limited role”.  Its disappointing but not surprising.  I’ve spoken to a number of liberal democrats in the past who have made it plain they support nuclear power.  Its also another example of them caving into the tories.

One thing I’ve never quite understood is why the political right is so keen on nuclear power.  Nuclear plainly cannot be built without subsidy and the right should hate this.  In fact the treasury and the chancellor don’t like it, for this reason, although he is keen on shale gas and is throwing tax breaks at that instead.

The current situation for nuclear new build in the UK is looking perilous to say the least.  EDF have delayed and delayed on announcing whether they are going to go ahead with Hinckley C.  Currently they are supposed to be announcing this in September.  We are more than half way through and nothing, although with a lib dem being the energy and climate change secretary of state maybe the motion and conference presaged something.  The other European companies as we wrote in our book have dropped out leaving the Chinese, but its very quiet on that front too.  Maybe “limited role” means just Hinckley C?  The problem is money, the nuclear power industry want huge subsidies for up to 40 years above 10p/unit, a figure the treasury are rightly very worried about crossing.  They also are said to want this figure when not generating as well.  Currently wave and tidal, solar and offshore wind get more than that.  However the hope is to get offshore wind to 10p and within a few years (5 at max) solar will not require any subsidy at all.  Wave and tidal are decades away from being major players.  One problem is with nuclear power (amongst many) is how slow it is to build, removing it as an option to tackle climate change or energy security.

Meanwhile one country is pressing on with its nuclear power plans.  Iran has announced today its going to build another nuclear reactor.  The new President Rouhani is a breath of fresh air.  Whilst I am suspicious of Iran’s motives we should put the diplomatic outrages against the US and UK diplomats since the revolution behind us, negotiate and lift sanctions for a short period in the meanwhile to give the moderates something to show for it.  Pray for this.  Maybe the answer is to get the Iranians to build Hinckley C…
