To R.Horlock re old housing and poor damp course, have you considered Freezteq damp proofing? The firm is based at Blockley near Moreton in Marsh, Gloucestershire
Having worked in ECO, the issue with the built environment is the quality of the old housing stock. You can''t put cavity wall insulation in a property without a perfect damp proof course, otherwise it will create damp. A high % of older properties have issues with the damp proof course - an expensive issue to fix.
The attitudes to renewables are the same as for energy efficiency - it''s a bottom line issue and there are no real compliance drivers. Much of the purchasing and attitudes to energy efficiency and carbon are those of the A-level managers. B level mangers will usually delegate compliance-type work, such as ESOS and CRC, to their A team (and not in the sense of the best), whilst C level people often just ask their B''s and A''s "How''s it going - are we done yet?". The main reason for this, I believe, is that energy spend for most businesses is less than 2% of turnover and not ''mission-critical''. This results in it being a lower priority in reality than anything that is ''mission critical''. This is about perceptions rather than reality, so talk about sustainability and marketing or HR-related aspects of such things is just not listened to. Until government accepts that this is a high priority and requires action , not just thinking about it, not a lot will change. The pity is that there are a lot of good deals available and should the government force action the rush will again dilute quality and make doing a good job more difficult, not less, I fear.
Hi Richard, if you register for the masterclass you''ll be able to watch it on demand afterwards. Hope this helps.
We will be exhibiting at the RWM exhibition at the NEC on the day. Will the masterclass be available to download afterwards please?
To be zero carbon is an impossible target, what should be aimed for is as low cost and low impact on environment, climate, and all ecosystem''s by employing as least natural resources as possible, making best use of sustainable recycled resources with as a long longevity and still able to be reused. Direct carbon use is just one aspect of climate change, ecosystem collapse is occurring because we are using far to many natural resources and unbalancing nature and natural forces. Crowd funding means spending money and all money directly represents energy to be released when spent So look again please at your methodology in arriving at zero carbon !?
Let us build as is the case in Germany where former nuclear sites are in conversion, the excess and day cheap energy lifts the huge underground pistons atop the submerged water tanks. Released at night these drive the water through the linking channels to turn the generators by that oldest of technologies, the water wheel. Reverse and refill during the day with wind and solar electrics, hydroelectric in the dark. Unfortunately this is not known as it should be.
"to store and discharge between 200 and 500 watts per sq m" It is watt.hours that is the measure of the quantity of electricity. Watts are a measure of the rate of usage of electricity. The above statement tells us very, very little. Richard Phillips
Well said indeed, Climate change has to be the most important issue that the Government is facing today, but appears to be somewhat half-hearted in its response, exemplified by giving P.P. for fracking to go ahead, why would you do that when sensible investment in renewables makes more economic sense as well as environmental. The Government is still too deeply embedded with the oil lobby to say they are committed to dealing with climate change, we should be on a war footing it is that important, tipping points are getting extremely close and will not be reversed. Come on Lord Deben shout louder please we are depending on you
Rod Mountain 08.08.18 As an environmental scientist, I have to say ''well said.'' But I would be more urgent in my message, knowing as I do the actual ( more pressing ) temperature rises as measured by 5000 universities globally. I have spent the last 10 years enabling the installation of technologies ''green.'' In the same year that we nearly gave Greece Euros 10,000,000,000 to bail them out, the UK government could have spent this money donating 100,000 solar PV systems each 100kW in size! This legacy would be saving global CO2 emissions for decades. Anyone working in the renewables industry will know what I mean when I say UK governments of all colour have been uncommitted /ambivalent /half-hearted when it comes to energy policy. So - needlessly we continue to have to buy coal and gas from abroad ( balance of payments deficit ) and seem to need foreign money to build what the world will surely judge in the future as the biggest ever white elephant: Hinkley Nuclear - giving a wholesale price of 9p per unit! We could be forgiven for thinking that May and Rudd have succumbed to the pressures of Brexit and turned into what John Gummer correctly calls flat-earthers!
Well said. I speak as a Chartered engineer who resigned from Gas turbine design at Rolls-Royce to install solar pv systems and now also design wave energy converters: I feel like the best course of action is to decarbonise the national grid as it is the low hanging fruit. Transport is a very challenging problem to solve as vehicles (air land and sea) need to carry their fuel - the combustion engine (IC and Gas turbine) has an incredible power to weight ratio which is why it works so well in transport. I suggest focusing on all static energy consumption through improved efficiency and decarbonisation of the supply of energy. Heating and electricity are the easiest ones to solve and are huge chunks of our overall energy consumption.
The "world now has more than 1TW of wind and solar capacity". The solar component fails every night, and is variable during the day. Overall solar generates no more than 30% of its "capacity". The same goes for wind. Actual generation, totally variable, totally non-dispatchable generates overall at less than 30% of "capacity". And if the potential power is generated when it is not demanded, storage is inefficient and expensive. But the business community make a lot of money. Your money, dear reader!!!! Richard Phillips
Get rid of the nuclear fission, out of date nonsense and this wont be necessary, renewables can, and will, provide all the power we need, when we need it. Meanwhile store the waste that this silly industry has produced in caverns deep under the Houses of Parliament, they introduced it, they should live with the result - and the half life is indeed thousands of years with certain of these obsolete fission materials.
Well said! This success storey ought to be shouted from the roof-tops, to allow the doubters to be able to join in as part of a consensus. However, the government still pursues short-term objectives. Isn''t it time to put airport expansion on hold until bio-fuel or hydrogen can power planes? Also, to reintroduce the fuel levy, back-dated until when it was frozen. That would encourage thrifty motoring, as well as raising much needed taxes from the petrolheads.
When you think that the most recyclable materials PET is difficult to recycle, in my town we can only recycle bottles, but in the next town over they can recycle all PET, until we get a coordinated recycling across the country we are not going to get into the top 10 countries for recycling. Once a coordinated recycling scheme is in place, we will be able to put clear instructions on the packaging as to how to recycle it (or not) this will allow consumers to choose products by ability to recycle, we can have national education for recycling, supermarkets can choose materials they know can be recycled by all. This is the elephant in the room and until the government legislates for a coordinated recycling scheme we are only going to make minor changes to what is being done today.
It is quite amazing that so much ignorance concerning radioactive should still be so unashamedly displayed. "many thousands of years"; no, a few hundred and HLW is gone, but don''t tell Ms Lucas, Bradshaw, Marrington, and Blagojevic. "obsolete 20th-century technology", this must be a reference to windmills. Yet another illustration of the ravings of those bereft, apparently of both knowledge and its basic science. Richard Phillips
There is also another consideration. If there was a Hydrogen engine-generator which replaced a petrol engine-generator in an existing EV type, it would bring about zero emissions at all times of use. There would not be any need for the heavy costly batteries as a result the battery pack could be severely cut and likewise the manufacturer could cut the price of said EV. The Point I make is that Auto Industry only has one perception of how Hydrogen can be used. But there are also elements who are blocking this potential so there are other factors outside of this debate.
Just to add to Clare''s comment on cotton buds. We at the Co-op replaced the plastic stems with paper back in 2006, and we removed plastic microbeads from Co-op brand products at least as early as 2001.
A useful summary, although as far as replacing plastic stemmed cotton buds with paper, consulting www.cottonbudproject.org.uk would have been useful. Waitrose was in fact the first UK supermarket to recently change from plastic to paper stems, while M&S and Co-op have been long standing retailers of own brand paper stemmed cotton buds.

electric & hybrid cars are not the answer ...the batteries are SO polluting from mining the raw materials to the eventual disposal..., what is going to happen to all the spent batteries after what ..., 5 or 10 year life? noise pollution from wind power is yet unknown but studies show that its having a huge impact with marine life. propellers from wind turbines are wiping out migrating birds. we need to enhance solar from our office and home windows, car windscreens .. there is so much out there.
