Dave , I checked the document via link with same result .
Cornwall would appear to be the ideal test bed for truly clean energy especially with solar and wave power. There must be more knowledge on wave characteristics than for any other location in the UK . I am sure Steamy would prefer the waves to provide energy rather than just provide natural facilities to encourage visitors.
With reference to the air quality strategy it is sad that this and other reports on anticipated impact consequences of air quality degradation are ignored. It was hoped that the influence of David MacKay would encourage due diligence and joined up thinking in energy decisions, it is stated that “ he is responsible for ensuring that the best science and engineering advice underpins DECC policy”.

I would imagine the problem is more down to the ongoing shift to diesel vehicles than biomass. Burning biomass is still relatively rare, but diesel cars are becoming ubiquitous. The newer ones do have DPFs but they aren't popular with owners, and it's actually cheaper to completely remove the DPF altogether rather than repair or replace it. Some drivers are even removing them before they break due to a perceived loss of performance. It's apparently completely legal to mod your car this way, and it's easy to have done.

Shall be there later doing some of my coastal erosion work (and getting a coffee). Tis blowin a hoolie at the moment.
News got it a bit wrong though, they said trees may be uprooted.
'I see no trees, you see tree?'

Bet there is a bus service as the railway line will be getting damp again, but the Emmets have plenty to do at Hartlands, it is the new WOW, apparently. Has a turbine (a VAWT that does not spin much) and an out door adventure playground (so glad that the EU money went to a good cause).
Must be half term week

Posted By: tonyWould it be fair or reasonable to use an annual mean figure

No it would not.
If there are safe levels and unsafe levels, with the unsafe levels only happening occasionally but still a risky exposure, you have to use Frequency Distribution rather than mean, median or mode.

If you tabulate enough data from enough places you should be able to spot trends and similarities in the distribution.
Once that is done you could fit a curve to the data and use that to predict from the mean the expected distribution. What they do for windspeed when using the Weibull distribution.
If you know the mean, min and max, standard deviation, skew, kurtosis and sampling rate you should be able to recreate the distribution within limits and accepted errors.

Other distributions are available.

Ah. I now see why the current crop of forecasters can never get it right.

Nature simply won't play the game and slip neatly into place in the modelling.

Nature is such a silly billy.

Had to laugh when I saw this.

Together with recent reports linking particular combustion pollutants to serious health problems for infants and the need for in depth scrutiny of UK energy combustion proposals becomes a priority,

This article indicates concerns surrounding the UK rush into EfW for provision of power
http://www.guardian.co.uk/environment/blog/2012/dec/11/jeremy-irons-trashed-film-waste]
Conclusion question in the article-
“What do you want people to do once they've seen the film?
I would like them to research whether there is a waste-to-energy plant planned for their area, and, if there is, to oppose it”
To illustrate the current waste reality DEFRA confirm 88kg/person reduction over the past 4 yrs and we are aware the current recycling benchmark is 70% with the recycling technology advancing so minimum 25yr feedstock sustainability for EfW becomes a serious problem. Authorities taking the incinerator route are already reporting a 30% shortfall requiring extended haulage bringing environmental and cost consequences. The landfill argument is lost so justification relies on the the need for power supply diversity but this argument requires serious scrutiny of inefficient resource use and much higher pollution burden created per unit of useful power out.

Current energy proposals indicate England and Wales are due to be the largest importers of biomass in the World and burning it in low efficiency powerplants creating levels of hazardous pollution much higher than Continental equivalents and guarantees air quality degradation with consequences. The decision to allow relaxed pollution limits in parts of the UK defies logic when aware of the transboundary impact.

This article adds to air pollution impact concerns
http://www.naturalnews.com/038244_air_pollution_autism_university_study.html
There are established links to other serious health concerns including cardio-vascular, respiratory problems, COPD, asthma, emphysema etc. We are subsidising burning technologies producing fine particle pollution hundreds of times higher than alternatives, that have doubtful carbon credentials and are wide open to abuse in use of material and process impact. Small combustion to energy processes create basic hazardous pollution equating to millions of additional diesel vehicle km each day, domestic contribution to pollution burden is rising rapidly and our inability to control the impact on neighbours is highlighted in this forum. Today in the press the fire service report a large increase in chimney fires and urge wood burner owners to clean flues at least quarterly. This indicates the level of pollution hazard created.
Current renewable combustion proposals are scheduled to create hazardous air pollution up to 10,000 times higher than gas per MWh of useful power out and there are projects due to import hundreds of thousands of tonnes and burn it below 20% efficiency with others scheduled to import millions of tonnes of diseased material posing a risk to indigenous plant life .
GBF comments confirm the knowledge is there to minimise the air quality degradation caused by combustion processes but sadly to date not being applied.

Saw a good one, "how to halve particulates pollution" install a drier before weighing particulates! this removes voc's and any damp and appears to reduce pollution by 50%, quite unfairly in my opinion.
