This is only a part of the picture, and depends upon a decision not to use coal in favour of another generator. Coal power will still be AVAILABLE. It is mandatory that all renewable generators are sources used as sources of priority; they have fist bite at the cherry, if they can be used they will be, above all other generation. This does not make them demand lead sources, indeed they never will be. They are "grab it if it available" sources, relying entirely upon fossil and nuclear generators to take up the duty when they are become incapable. And their times of impotence is totally out of human control. For ever. The greater the proportion of renewable energy available and obliged to be used as fist resort, the greater has to be the fossil or nuclear backup. This all makes our power expensive, and the poorest in out society pay the same proportion of their bill to support renewables as do the richer members with money-making solar panels on their roofs. Hardly social justice. But HMG do not understand this. Having a Cabinet without any member with scientific or engineering knowledge above A level at the very most, is no help to the dilemma in which we find ourselves. Mr Shatwell is quite correct in drawing attention to gas fired generation, at this moment 17.24GW, 46.7% 0f demand. Biomass is simply immoral and inefficient. Richard Phillips
Thank you for your clear explanation on this topic. Interesting to read there is no legal definition of biodegradable perhaps this is something that could be addressed during (and after) the current election?
In response to your article on the popularity of onshore windfarms. I think they are really great things to see, particularly against a blue sky and big white clouds .Modern ,clean, efficient silent, very safe, progressive ".The ideal power generator" They are ,after all ; only modern "windmills" they are silent, clean, efficient and they produce cheaper power.So what is there to object to? "Wild life" seem to like them (there are more birds around the local windfarm here than before and birds are not stupid, they don''t fly into winfarms they fly around them.). The last person i heard objecting to the local farm was an" incomer" to the area and misread the local feeling about the farm,she thought i was one of the owners of the farm simply because i said that i thought the farm a big plus for this run down coastal holiday area .and i thought it " a wonderful sight particularly up close. The same "objector" to this coastal windfarm parked her car and 5 dogs appeared ,non on a lead.the dogs proceeded to do their business on the carpark and then ran onto the beach to do the same there.

While this is an important moment in our energy history it must be taken in context. Coal has been in the process of being phased out for some years but those coal fired stations that remain where still burning coal last Friday as they would have still been "ticking over". This week we will almost certainly have to rely on them for extra power generation as it is going to be cold. Also how much of Friday''s electricity needs were provided by gas? Still it is a start on reducing our reliance on solid carbon but we must not "dash for biomass" to replace it as wood pellets are not as "green" as they are made out to be as they still produce particulate matter.
They fail to realize that the grid is design is for centralised power generation. The interconnection grid network isn''t designed for the maximum demand reverse flow of energy from battery EV cars or storage. The entire infrastructure will need to be revamped at the sub distribution level (interconnections at domestic/commercial connection levels). The same 6 cars charging in a close local area will have the same effect as powering the grid. The amount of copper within the infrastructure still wont support the reverse flow of energy. Smart meters will need to be incorporated into these EV cars to safely control the reverse flow of energy as the same issues exist regardless of energy direction to or from EV or batteries. This summer will see the lowest energy consumption in the UK, the grid is now offering incentives for users to draw more power so that the base load generation can still operate (gas coal nuke), 25% renewables currently could cause the grid to collapse from uncontrolled solar and wind energy production entering the grid. http://www.gridwatch.templar.co.uk/
Interesting read, thanks for sharing.

Hi David Great reply article and brilliant factual information here too. I supply a compostable bag here in Ireland that is made with Natural Resins and Modified Pollyester. I have personally put these bags through an inhouse commercial composter and they ''Disappeared in 17 days''. Had the bags and food waste placed inside a nylon net bag so as to retreive and monitor the bags journey. The Green cornstarch variety only break down circa 50% in the same time frame with any undegraded material being landfilled with all other blow off materials at end of process. Our bag also takes 20kg + in weight and is heat resistant to 70'' + for commercial use. Denis Lawlor www.brownbinrescue.ie
Hi, Please could you let me know the name of the report that this article references and/or where I could get hold of it. Many thanks
Great article and adds clarity! One question... What is the relevant standard and logo we should be looking for on compostable bags?
V2G is a great concept, visioning low carbon energy infrastructure that we all contribute to. In the short term the most important reason for growing the EV sector is to decarbonise transport and reduce air pollution.
David, thanks for challenging our blog: have you anything more to add as our response will come shortly? Luke (Clear Public Space Ltd)

Excess energy generated . . . this building is indeed special as it ignores the Law of Conservation of Energy - that you cannot create or destroy it, rather you convert it from one form to another!!
CCS must be coupled to utilization as well, absolutely essential. We cannot simply store the vast quantities of this gas and trust that it will never escape en masse - it will - with devastating consequences local to the escape. Also, the main reason for CCSU, as it will become, is reduction in global pollution, reducing our ability to breathe and acidifying the oceans - not global warming.
Whilst the District Heat center may be super 100% efficient some HIUs installed in newly built apartments feature poor efficiency ratings. In fact some perform so badly the customer would be far better off using an obsolete BAXI bermuda back boiler. To add insult some heat providers claim to offer a price promise guarantee yet fails to take into account the efficiency rating of the supplied HIU. Also worth checking out the Heat Trust website - currently they ask the heat customer to enter the district heating units used and then somehow calculates an alternative gas cost. Allegedly the scheme to protect customers fails to recalculate the customers units taking into account the energy loss after the meter measurement. Allegedly by including poor efficiency hikes up the alternative gas comparison unfairly. Heating hot water from 43c to 60 in a 150Litres tank needs 2.98kWh of energy. However it has been recorded a heat-only HIU requires twice amount - by doubling the units and then multiplying by 1.25 as a comparison is a misrepresentation
This report reflects Anesco''s own press release, which does not distinguish between how much energy will be stored (MWh) and the power available (MW) when it is released. Different technologies have different characteristics, e.g. capacitors can store relatively small quantities of energy but can deliver high levels of power for a very short period, while at the other extreme storage as hydrogen or simulated natural gas can store more energy but delivers it over a much longer period of time. I''m a layman, but I can appreciate that for grid balancing purposes we need a variety of storage systems with different characteristics - at the capacitor end to deal with everyone switching on their kettles at the end of a popular tv programme, and at the other end to deal with major generation outages or unusually cold weather. I recommend the REA 2016 report, referenced in and linked from the Edie report of 10/10/2016 entitled "REA calls for energy policy reform to unlock storage megashift." The REA report addresses these issues
Diesel scrappage sounds good but scratch the surface and you realise you are just creating (demand for) more new cars, which is far more polluting than running an older car - albeit the pollution is occurring in a different location. Out of sight, out of mind?
Hi Martin and Ian - thanks for flagging this up. Anesco is number 78 in the Sunday Times Virgin Fast Track 100 league table, which ranks Britain s private companies with the fastest-growing sales over the latest three years. http://www.fasttrack.co.uk/league-tables/fast-track-100/league-table/ To clarify, Anesco is not on the Disrupter 10 list. The changes have been made to the original article. Thanks, George
CO2 is very much a gas of choice now, at Mitsubishi Heavy Industries we are really seeing a large growth of businesses wanting the Q-ton installed. Its great to see that more uses and applications for the gas are being found. Scotland is always at the forefront of renewable technology, well done!
@Ian. one for Edie to investigate then! This link shows that they are in the 2017 Global Cleantech 100 (https://i3connect.com/gct100/the-list) and I know they are good at getting awards but the disruptor didn''t seem right.
