Got even more wood ?
February 3, 2010
So DECC has launched a consultation document package for its Renewable Heat Initiative (RHI)
Lots of good stuff in there, but the bit that I’d like to comment on is the incentivisation of wood chip/wood pellets for domestic heating.
Feel free to correct me if I’m wrong but to me this provision looks like a commitment to an effective long term taxation of the rural poor. Its a bit counter-intuitive at first sight, after all how could an incentive to use local renewable biomass result in higher bills ? Well, its all to do with having a limited land package available to provide that biomass.
There is a distinction in the consultation between biomass that originates from wood, that which comes from grown for energy crops and that which is the result of existing agricultural processes (such as straw), but what concerns me is the interaction between existing managed woodland and possible new energy crops such as mycanthus and willow. The problem is that the RHI incentives only relate to pellet or chip burning boilers effectively replacing fossil-fuel burning boilers and central heating. Standing hardwood doesn’t make economic sense for pelletisation or chipping, its wears the machinery and takes more time and energy to produce and harvest.
What the consultation leaves out (and I can’t find mentioned anywhere in the document package) is the economic impact on existing wood users and those who cannot replace boilers. In other words me !
My situation is as follows: I live in a little village in Cornwall that is a good 10km from the nearest gas main. Most houses in the village use coal or wood to supplement Economy-7 electric heating. In many ways its a typical granite-built miners village. No cellars, very little outside space, houses are well over 100 years old (so low ceilings) and built of thick solid stone walls. Speaking for myself only; I don’t have a boiler, just an immersion heater that I turn on if and when I need hot water. I don’t have central heating, just a single electric storage heater that is powered by Economy-7 over-night. I rent the cottage and have only a small amount of space outside. I am not unusual in this county.
What I do have is a nice big fireplace that I can settle down in front of in the evening. I burn wood in that grate and buy my wood from local suppliers or one of the many local shops who sell 5kg bags of split logs over the counter.
My concern is that if pelletised or chipped wood becomes a lucrative product, managed woodland in the area will shift towards those products and away from larger trunked species suitable for splitting and domestic use. It’ll take time, I don’t expect to see the price that I pay for wood to rocket overnight, but the house that I live in will be around for at least another 100 years so the issue is not gong to go away. Over the 20-50 year timescale, by shifting the forestry from bulk wood to processed chip you will see a price differential mount that penalises those living in houses that cannot be physically altered to accommodate pellet burning boilers. These houses are generally smaller, cheaper and occupied by those less able to cope with price rises. Effectively this is an incentive that will put the rural poor at a greater disadvantage than ever.
I like the idea of increasing biomass use as I previously stated in Got Wood ?, but this particular policy seems poorly devised.
Energy Security = Energy Interdependence Addendum
January 20, 2010
Interesting presentation by Jeff Rubin at the Business of Climate Change conference in Toronto in Sept 2009
Its 45 mins long, but well worth it to see how an experienced (and charismatic) financier sees the issues connecting energy, trade and globalisation. I think his timings are wrong, but otherwise its a reasonable reading of a potential future.
You’ll note that he never once mentions energy independence, only alludes to energy security but never uses the phrase, and speaks about the development of regional economies as oil costs erode labour price advantages currently experienced by emerging economies. Don’t misunderstand, its all about energy security, but he doesn’t fall into the rhetorical trap of invoking overtly nationalistic tendencies. He uses protectionist measures (carbon tariffs) to get to his view, coupled with internal carbon pricing, but everything is in believable economic terms.
If we consider Canada, and specifically British Columbia (BC), as a thought experiment in this context its interesting to see the North American western seaboard as an emerging power in Rubin’s new re-jigged, less global economy. Yes, there is a focus on resources for export in BC, but with the amount of hydropower and BC’s commitment to zero carbon electricity there may well be a competitive advantage to base a regionalised economy along that seaboard, with population and industrial centres served by natural resource flows north and south of the 49th Parallel.
Apart from BC, the combined regional energy policies are supportive of a low-carbon transition with gubernatorial and state-level initiatives favouring low carbon energy sources in California, Oregon and Washington State. A cursory reading of their respective policy positions shows that energy independence is not a rhetorical standpoint that is used strongly, except by the Governor of Oregon. There are good (and reasonably obvious) reasons for this. BC and Washington State have excellent hydro power resources, and both have potential to raise the electricity production from small and medium-sized hydro. This reduces their dependence on energy imported from outside the region. California is known for its innovative technology and progressive policies in the energy field, so has much to gain by driving a new industrial sector.
But lets take a step back to Jeff Rubin’s point about localising production of goods. That implies localising non-energy natural resource production as well as energy. The western seaboard is in an enviable position to do this. Pretty much every kind of natural resource can be found in this part of the world; timber, fish, metallic ores, agriculturally productive land. As a region it’s got it all. But !
But on its own BC doesn’t have a large enough consumer-base to support a fully vertically integrated economy. Apart from the 3 million folks in the Vancouver area, its mostly forests and mountains. Likewise it doesn’t have the full range of agricultural products that most of us have come to expect in the last few decades, due to its climate. It has an excess of low-carbon power and raw materials (and no shortage of ingenuity). It could be energy independent, but it would end up paying over the odds for the food and manufactured goods that it seems likely would be produced in California in this new regional emergent economy. The binding cross-border factors could be water and electricity, but BC should also look at processing of those raw materials to add value to them prior to export.
So an internal drive to a progressive energy policy fits with a regional strategic economic vision. Energy security is allied with food and water security and internal economic coherence.
I think I’ve just convinced myself to move to Vancouver
Copper in Wind Power
September 24, 2009
Based upon the research that I detailed in my previous post we can say the following with a reasonable degree of certainty;
The UK will need to increase its raw copper imports by at least 10%, from 2007 levels, if it is to achieve its wind power objectives AND manufacture the components of that new industry on British soil.
The further offshore that wind farms are built, the more copper they use per MW of installed generating capacity (kind of obvious but you still need to crunch the numbers to show it).
The UK currently exports more copper scrap per year than would be required by the proposed new wind industry, based on figures from the British Geological Survey.
The copper cables that are being buried during wind farm construction are not planned to be recovered upon decommissioning. This policy constitutes a planned consumption of copper that is contradictory to the principles of sustainable development since it ‘offshores’ energy consumption and environmental impact associated with copper production in preference to reuse. However, it provides the UK with a readily available source of copper in the form of recoverable buried cables with a known location. This could be considered a hedge against security of copper supply in the long term.
I have found no evidence that this possible long-term hedge against copper supply risk is a conscious and explicit government-led policy, but given that we have another 3 billion people coming to tea before 2075 and that copper has no viable substitute for 100% of its applications, it sounds like it might be a sound policy from a security of supply standpoint. Completely unethical of course, harvesting resources from other nations to hoard for future use, pushing up prices by artificially constraining supply and forcing developing nations to utilise resources earlier in their development cycle than they would have otherwise. But pragmatically better to establish a new form of copper mine within UK territory before supply really gets constrained.
The question is what are the alternatives ?
The obvious answer that I came up with was recycling. The UK only recycles about 42% of its scrap copper (from the BGS again). Of that 37% comes from manufacturing (offcuts, the remains after pressings, and the like), the rest is recycling as you and I know it. The old copper heating pipes and wires from old motors that we have finished with only make up 5% of the UK’s total copper (re-)consumption, 19 times more comes from new mined resources and from the pristine factory scrap. That is massively wasteful on all sorts of levels.
I recently read a paper on a Markov Chain analysis of copper (Eckelman & Daigo, 2008) use that concluded that the average copper atom was used 1.9 times for technology in the 60 years between its extraction from geological reserve and its dissipation back into the environment. If we assume that copper should theoretically be used around 20 times before it is dissipated (using a conservative 5% reprocessing loss), we currently have a copper system in the UK that is roughly 10% efficient.
That has to offer massive opportunities to the copper recycling business, as well as opportunities to decrease the environmental impact of the copper cycle without compromising the ability of the UK to meets its wind power goals.
Energy Security = Energy Inter-dependence
July 25, 2009
You can be energy secure by being energy independent or energy self sufficient, so the populist argument goes. That is, if you produce all the energy that you need from sources that are within your own national territory, so it must mean that you control every aspect of their production from price to pollution.
Nice rhetoric if you can afford it. Few countries can. Few countries even know their own supply chains well enough to guess at whether energy self-sufficiency is achievable.
At a guess, America could probably be energy self-sufficient for the next couple of hundred years or so. It would have to break pretty much every trade agreement that it ever signed up to, and switch a large portion of its industrial endeavor towards energy provision, but it could probably do it. Canada would collapse as an economy, Mexico would too, and two long and winding land borders would become ‘hostile’ rather than ‘friendly’. The US would become pariah state in environmental terms as well as economic since the majority of its indigenous resources are in the form of coal, but hell, who cares with walls thick enough and high enough to keep the Mexicans and Canadians out they couldn’t hear anyone else either.
Europe could never be energy self-sufficient, but it has never tried to be. Europe has too much industry for the number of people packed into the area for the myth to hold. And Europe knows about this stuff, after all the EU was conceived, in a large part, to avoid just such a situation with economic have and have-nots in close and envious proximity.
I propose that the founders of the European idea were right that energy security is not energy independence. I propose that energy security is energy inter-dependence. That moving towards an atomisation of energy source and use will, by necessity, require an atomisation of self-interest. Is a world culture of “screw you too” really what we want ? If nothing else it will severely restrict trade opportunities.
Or maybe I’m wrong and we should fully embrace the concept of enlightened self-interest and abandon the nation-state as an entity. A global return to the city-state, each self-sufficient with energy and food provided by its own hinterland. The good old days, yes ? The Borgias certainly seemed to thrive.
I’m not sure that we’re quite ready for that, but I see no reason why the concept of nationhood should be permanent. After all it was only invented a few hundred years ago. We’ve had it for longer than ipods, but for shorter than paper or the wheel. But what constitutes a nation where global debates are conducted here and are available there, may mean something fundamentally different by the time internet reaches everyone.
Its a simplistic argument, I know, but beware of simplistic policies. They are insidious. It took 30 years for the Berlin Wall to be torn down.
Update: Nice little summary of protectionist measures from The Times
and the organisation that it mentions – Global Trade Alert
