Looking backwards, looking forwards


The New Year is typically the time when we reflect on the past and then look forward to the coming year in the hope that it will be better.  The desire to have something to hope for that will improve our life is strong. The month of January gets its name from the Roman god Janus who has one face looking back and the others looking forwards. He is the god of gates and transitions.

Often, we can’t move forwards unless we have looked back, retraced our steps and asked some serious reflective questions such as: Is there a pattern in my behaviour and relationships that keeps repeating itself? Is there something I need to acknowledge and take responsibility for? Do I recognise my reactions could have been different? The key is to learn from the past and not just glance at it, so we don’t get stuck in the same old patterns of behaviour. If we do this well, we will grow and develop ways and means of working better with others; as well as being authentic to ourselves.

SHARE Hydro – update


By now, we had expected to have a live website, updated continuously, showing the potential of the Lansugle stream to provide a small scale generation scheme .

Back in 2020, SHARE volunteers had already completed the metalwork for the measurement weir and reinforced the banks along the short stretch of the stream that suffered flooding in November 2019’s torrent. We completed putting in place a 65mm (2 ½ inch) high weir ready to use the electronics to measure the fall over it. We’d checked in the Environment Agency’s guidance that a measurement weir didn’t need any additional permission. But for reasons unknown to us the Environment Agency took an interest in our work, and sent a fisheries expert to take a close look, and we were then advised that changing the flow from turbulent to smooth along the weir structure (just three feet long) would contravene the Salmon and Freshwater Fisheries Act. It turns out that we would need at least three extra items: a salmon ladder, an eel pass and a supplementary licence, the application fee for which is an additional £1500!

The impact of the Environment Agency intervention was that the metal weir structure had to be removed. This was done quickly and the site completely restored to the state that it has been in for the past 50 years. The purpose of the metal weir was to straighten and smooth the water, resulting in “laminar flow” over a clean edge. This, in conjunction with a water depth measurement system, would have enabled flow over the weir to be very easily calculated, with little manual intervention. It would in fact have been possible to monitor the flow closely over a 12 months period, in a fully automated way. Occasional site visits would have been necessary to ensure that the metal channel and weir remained clear of obstructions such as branches and other debris.

But we’re determined to complete what we originally set out to do; it’s just that we had to find a method that meets these additional regulations. We still want to characterise the catchment area and stream flow, throughout the year – even on a weekly basis. We also want to be able to assess the power generation potential of small streams such as this one, and so put ourselves in a better position to be able to subjectively judge alternative potential power generation sites. Consequently, we have purchased a small water turbine flow meter and started to measure flow with this equipment on a regular basis. The site has concrete piers that were used in the distant past to provide the greater head of water needed to drive a water pump. These piers provide an area that constrains the flow and makes it relatively easy to carry out a matrix of flow speed measurements. Although it is still early days, we are gathering some interesting results.

We have already seen that flow can vary widely in a short space of time. In the dry weeks of November, the flow would only have been sufficient to generate around 1kW of electricity. In early December, following heavy rain, 6kW electricity generation would have been possible. 6kW round the clock, entirely independent of wind or sunshine would be a very valuable local generation capacity – equivalent to the average energy used to power around 15 homes.

Green Tips for Black Friday (and beyond)


The recent COP26 event in Glasgow has got everybody thinking about how to be “more green”.  While it’s clear that governments around the world need to take action, they aren’t the only ones.  So what can we as individuals do in the meantime? There are heaps of advice and information “out there”, but as my mother used to say, “Enough is as good as a feast”, so here in a nutshell are a few ideas:

Black Friday – not all it’s cracked up to be

(excerpts from an article on the Consumers Association Which? website, Make Black Friday green: Five ways to shop small and buy better

Many winter bargains aren’t as attractive as they first seem.  So is it worth forgoing the shopping frenzy and seeking out smaller, independent shops and more sustainable shopping instead?

Since it caught on in the UK around a decade ago, our enthusiasm for Black Friday has grown exponentially. According to Statista, shoppers spent £7.95 billion over the 2020 Black Friday weekend.

Offers now appear weeks in advance, and many continue well into December.

But not only can the deals sometimes be duds, the November shopping rush can also add to your environmental impact.

If the rush for bargains is leaving you cold, here are our tips to ensure you don’t end up regretting a purchase, plus some alternative ways to shop.

  • Do your research before buying
  • Only buy what you need
  • Spend your money where it makes a difference
  • Buy nothing on Buy Nothing Day, 26 November 2021

The UK Buy Nothing Day campaign began in 2000, with a simple message: Shop less, live more.

You can participate in Buy Nothing Day by literally doing nothing at all. It’s a 24-hour detox from consumerism, and it’s free.

So if you’re determined to avoid over-consumerism and save money this Black Friday, Buy Nothing Day could be the answer.

Also, explore the Which? Website for ways to save money while reducing your carbon footprint, and look out for this logo in their many product reviews.

Do you really need a new computer?

With the introduction of Windows 11 coming up shortly, many people will feel they are forced into buying a new laptop or desktop computer. But your old computer may be capable of upgrading – you can find out how to check here…

Machines that can’t upgrade will still be perfectly capable of doing everyday tasks such as browsing the internet, word processing, and playing videos. Before you go out to buy a new machine, have a look at what your requirements are.  Sometimes it may just be a matter of upgrading a component (e.g. a new stick of RAM) instead of buying a whole new machine. If you do need a new machine, then consider donating your old one to someone in need https://www.bbc.co.uk/programmes/articles/5SqHJMTKZx5sYhlltXJvB1Q/give-a-laptop

Cold Snap – Energy Efficiency

The temperature has dropped by about 10°C in the past few days!  If your house is anything like mine (1980s bungalow!), you’re really feeling the difference, but what can we do about it? Make a note to do some research before taking radical action, but there could be some easy solutions.   Have a look at our SHARE booklet “A Guide to Saving Energy In The Home” for inspiration.

Guide to Saving Energy

South Hill Carbon Footprint

SHARE is revising their carbon footprint analysis from October 2019, and will share the detail in the new year.  Households in South Hill are relatively well-off, with an average carbon footprint roughly twice that of the UK average. So far it is clear that as a parish our main carbon emissions come from heating (mainly oil), groceries and travel.

Heating Is your precious warmth leaking out through windows and doors? Close curtains and doors to keep the heat inside. Turn your thermostat down by 1°C. Can you feel the difference? If so, are you wearing a sweater? If not, go get one! Seriously though, most people wouldn’t notice the one degree difference, and it can result in huge savings, of cash and carbon.

Is your house properly insulated?  It can be difficult and expensive (though not impossible) to retrofit an older property with external or internal insulation, but there are some simpler solutions (e.g. thick curtains, draught excluders, insulation of roof spaces). When the time comes to replace that old fashioned oil boiler, be prepared to consider the greener alternatives.  If your house is well insulated, a ground source or air source heat pump could be the answer, ideally powered by renewable energy (e.g. solar panels). There are currently incentives available from the government, such as Renewable Heat Incentive (RHI) and the government’s recently announced heat pump grant scheme.

Groceries Buy your food locally to reduce the amount of food miles, and buy seasonal.  Think rich soups and warming casseroles!  There are many local suppliers that you can buy directly from, for example our advertiser Callington Fresh Produce, or Dupath Farm Shop,  Applejack Barn and Tamar Valley Food Hub.  Meat farmed locally has a much lower carbon footprint than imported meat, so check out for example our advertiser Phil Cole (Coombe Bridge, South Hill), or Chris Rounsevell or Tamar Valley Meats.

Travel Can you reduce your mileage by car sharing, or using public transport?  If it is local, walk or cycle instead of using your car. Consider working from home if you can. Even just working from home for one day a week can make a big change to your annual mileage.  Consider taking a staycation instead of a faraway holiday.

SHARE News Bulletin October 2021


SHARE AGM

Our AGM on September 22nd was well attended, firstly at an informal “board report” session outside the Parish Hall, to show what we do and progress made during the past year.  The second, more formal part of the meeting was conducted inside the Hall, and was rounded off with drinks and snacks so that people could continue to chat.

It was especially good to meet and put names to some new faces.  Membership continues to grow and now stands at 109 full members and 77 associate members.

Draft minutes of the meeting are being circulated to members who were present, and will in due course be published on our web page (https://south-hill.co.uk/share/share-member-area/)

Insulation, insulation, insulation!

A well insulated house

There’s a great deal of talk about “retrofit” just now.  Houses built without a high standard of insulation (and this includes many being built at this very moment) can never hope to be truly energy efficient without addressing this problem.  

At the recent Cornwall Home Improvement & Self Build Show at Wadebridge, Sue went with the intention of finding out more about retrofit, but was a bit disappointed to be honest.  There were plenty of stands selling solar PV, air and ground source heat pumps, even MVHR (mechanical ventilation and heat recovery) systems, but besides being expensive to install, without high standards of insulation in homes, these can also be expensive to run.

Sadly, we missed a recent talk given by Kate Royston of TEC (Tamar Energy Community), “Retrofitting your home – What’s this all about?” .  Kate has kindly made available the presentation used for her talk – see attached.  She says costs are coming down all the time, and the ones in the presentation are on the high side.

Kate would be happy to come and talk to our members about this.  Please contact SHARE@south-hill.co.uk if you’d be interested.

Out And About

We’ve been thinking about possible visits to places of interest. 

One example is the tree nursery and a new rainwater harvesting system at Meeth Quarry near Hatherleigh in Devon (https://www.devonwildlifetrust.org/nature-reserves/meeth-quarry)

This Devon Wildlife Trust site has been developed from an old clay quarry whose industrial past has produced a fascinating landscape for wildlife today.  With 150 hectares of nature reserve we should be able to have a good walk and observe abundant wildlife too.

Trebartha, nr Launceston

We’d also like to visit Trebartha, near Launceston, where as well as extensive gardens they have a hydro-power turbine installed in 2015.  Trebartha Estate opens its gardens to visitors through the NGS – National Garden Scheme.  The next open day is in May 2022.

At a recent open day we learned that “water comes from an intake area, through a 1.2km stretch of pipe dropping 90m down to the turbine house.  The turbine is a 4 jet vertical shafted Pelton wheel with a 350kW generator.  It is estimated to generate an average of 1000MWH of energy per year – enough for about 200 homes – which is fed into the national grid.”  Naturally we’re interested in this as it links to our own hydro feasibility study.

There may also be an opportunity for us to learn more about methods of farming which are more in tune with the environment – fans of the Archers may have heard talk of “herbal leys” and such like!  Example: https://www.facebook.com/LeanneBarriballbiz/videos/1033684474135257

If you have any ideas for SHARE visits, please let us know.

Unlocking, AGM and Big Green Week


In advance of our SHARE AGM event, to be held at South Hill Parish Hall from 7.30pm on Wednesday September 22nd, we are contacting all members informally.  This message includes important information for members regarding the election of Directors.

As music fans will know all too well, during lockdown all gigs were either cancelled or postponed. At last that situation is changing as we head into ever more freedom. There has been a knock on effect; a lack of available venues, as everyone wants a stage at once.  The SHARE AGM has been affected by the same issues, as we’ve had to postpone last year’s AGM until now. The similarity with your favourite band is that venues have become in huge demand. Our own Parish Hall is seeing a great upsurge in bookings, taking advantage of its refurbishment.

We have hatched a Cunning Plan:  the format of the AGM will change slightly.

This September sees the national Great Big Green Week, (18th to 26th September) and we’ve chosen to hook into that for our Annual General Meeting.

SHARE – Out and About Again


Lethytep Conservation & Wildlife Haven

In July, Saltash Environmental Action (SEA) arranged a visit to Lethytep for their members, which was publicised in the SEA newsletter.  Seeing this, we asked if some SHARE members could join in and included an invitation in our latest Member email bulletin.  In the end, only four of us were free to go on the trip, so Geoff, Mike, Ali, and Sue joined the lovely SEA members and Philip and Faith Hambly for the afternoon.

Philip and Faith have transformed 52 acres of meadows, lakes and ancient woodland into habitats that they manage for wildlife.  The amazing wildflower and hay meadows are managed the old-fashioned way using only carefully-timed grazing and cutting, resulting in a rich and varied habitat.  Though probably not financially viable as a working farm, Lethytep is a valuable resource for biodiversity and wellbeing and is open to visitors by arrangement and on planned open days in June and July each year.

Soil Samples for Mining Company


Deep Digital Cornwall and Cornwall Resources: Regional fieldwork supporting university research and data hub.
Over the next few months, you may meet field teams from Cornwall Resources (CRL) working in the local area. This work is being conducted as part of Deep Digital Cornwall, a £4.1m project comprising a consortium of regional companies and research bodies, led by the University of Exeter’s Camborne School of Mines (CSM), in which CRL and Cornish Lithium are delivery partners. The project is funded by the European Regional Development Fund (ERDF), and the UK Government. The objective of this work is to generate an open-source sub-surface data set to use as demonstration data at a new ‘Digital Hub’ being built at the Camborne School of Mines (at the University of Exeter’s Penryn Campus). The resultant data will be of relevance to end-users including in the farming, environmental, and mineral exploration fields, as well as for scientific research and general interest. A brochure on the project is available at https://deepdigitalcornwall.org

CRL are helping to deliver work in the area to the west of Kelly Bray, including in the parish of South Hill and Callington and Kelly Bray. Work is small-scale and low impact and consists of soil sampling and analysis, and a gravity survey. The soil sampling involves collection of small (<500 g) soil samples with a hand-held powered auger, from depths of 40-80 cm below the surface. These samples are then analysed for over 50 elements. Gravity measurements are non-intrusive, and carried out using an instrument that measures the earth’s gravitational force at a given point with a high degree of precision. By combining this with accurate topographic data, variations in gravity can be modelled, allowing interpretation of sub-surface variations in geology, such as the presence of a granite, or the presence of underground voids.

Two teams are working outdoors, in all weather, to collect soil samples and gravity measurements. The teams are composed of three graduate geoscientists gaining vital early career work experience, and one local resident trying his hand at something new. Landowners will be contacted to request permission for land access, and to ensure that any impacts, for example on stock movements, are limited.

All data collected under the Deep Digital Cornwall project will be made open-source, available to anyone interested, including farmers, other land users and local residents.
Further information on the above can also be found on the Cornwall Resources website: https://www.cornwallresources.com/deep-digital-cornwall

Cornwall Resources remains focussed on Redmoor, near Kelly Bray, where it has been working since 2017, and where it has met with considerable success – defining a world-class underground tungstentin-copper resource. However, the company is pleased to be able to facilitate the Deep Digital Cornwall work, which will put their already-discovered deposit into regional context, and show that Cornwall is at the cutting edge of earth data collection and interpretation.
If you see our teams at work in the field, feel free to say hello. If you would like more information, or would like to be informed when the data is released, please do not hesitate to contact Jeff Harrison by email jharrison@strategicminerals.net or on 07403 568770.
