Practical On-farm Renewable Energy event at CAFRE’s Enniskillen Campus

The annual “Practical On-farm Renewable Energy” event has now become a fixture in many peoples calendars following its success in previous years. The event will be held once again on Wednesday 26th February at Enniskillen Campus. This is a FREE event and is open to the public from 1.00pm – 9.00pm. DARD has again joined forces with the UFU, and AFBI to provide practical information for farmers and the rural sector about the various renewable energy options available for their businesses

Renewable energy technologies continue to offer significant potential to improve the competitiveness and sustainability of farm businesses through reducing and enabling additional income streams, when employed in the appropriate situation. This event seeks to assist farmers and growers with identifying which technology, if any, is appropriate for their own business (or domestic) situation. It also aims to provide information and contacts which will aid progress through the many procedures required to bring such projects to fruition.

 There will be a series of seminars throughout the day highlighting local case studies of the main renewable energy technologies; wind power, biomass production and utilisation, biogas production, solar hot water and PV, micro-hydro and heat pumps. A second series of seminars will deal with many of issues facing those considering installing a green energy source. Topics covered will include the proposed Renewable Heat Incentive (RHI), grid connection, planning, NI Renewable Obligation Certificates (NIROC’s), marketing NIROC’s as well as finance, business planning and funding options.

Being Green – our generation didn’t have the green thing back then!!

The following piece ‘Being Green’ has been circulating on various social media platforms over the past few months and it really struck a chord with me. Like the woman at the checkout we didn’t have the ‘green thing back when I was growing up but everyday we were doing the ‘green’ thing without actually realising it.  Just take a few minutes to read it through and you too will see how easy it was, and still is to be green.

Being Green!

Checking out at the store, the young cashier suggested to the older woman, that she should bring her own grocery bags because plastic bags weren’t good for the environment. The woman apologized and explained, “We didn’t have this green thing back in my earlier days.” The young clerk responded, “That’s our problem today. Your generation did not care enough to save our environment for future generations.” She was right — our generation didn’t have the green thing in its day.

Back then, we returned milk bottles, soda bottles and beer bottles to the store. The store sent them back to the plant to be washed and sterilized and refilled, so it could use the same bottles over and over. So they really were truly recycled. But we didn’t have the green thing back in our day.

Grocery stores bagged our groceries in brown paper bags, that we reused for numerous things, most memorable besides household garbage bags, was the use of brown paper bags as book covers for our schoolbooks. This was to ensure that public property, (the books provided for our use by the school) was not defaced by our scribblings. Then we were able to personalize our books on the brown paper bags. But too bad we didn’t do the green thing back then.

We walked up stairs, because we didn’t have an escalator in every store and office building. We walked to the grocery store and didn’t climb into a 300-horsepower machine every time we had to go two blocks. But she was right. We didn’t have the green thing in our day.

Back then, we washed the baby’s diapers because we didn’t have the throwaway kind. We dried clothes on a line, not in an energy-gobbling machine burning up 220 volts — wind and solar power really did dry our clothes back in our early days. Kids got hand-me-down clothes from their brothers or sisters, not always brand-new clothing. But that young lady is right; we didn’t have the green thing back in our day.

Back then, we had one TV, or radio, in the house — not a TV in every room. And the TV had a small screen the size of a handkerchief (remember them?), not a screen the size of the state of Montana. In the kitchen, we blended and stirred by hand because we didn’t have electric machines to do everything for us. When we packaged a fragile item to send in the mail, we used wadded up old newspapers to cushion it, not Styrofoam or plastic bubble wrap. Back then, we didn’t fire up an engine and burn gasoline just to cut the lawn. We used a push mower that ran on human power. We exercised by working so we didn’t need to go to a health club to run on treadmills that operate on electricity. But she’s right; we didn’t have the green thing back then.

We drank from a fountain when we were thirsty instead of using a cup or a plastic bottle every time we had a drink of water. We refilled writing pens with ink instead of buying a new pen, and we replaced the razor blades in a razor instead of throwing away the whole razor just because the blade got dull. But we didn’t have the green thing back then.

Back then, people took the streetcar or a bus and kids rode their bikes to school or walked instead of turning their moms into a 24-hour taxi service. We had one electrical outlet in a room, not an entire bank of sockets to power a dozen appliances. And we didn’t need a computerized gadget to receive a signal beamed from satellites 23,000 miles out in space in order to find the nearest burger joint. But isn’t it sad the current generation laments how wasteful we old folks were just because we didn’t have the green thing back then?

No computers or electronic gadgets back then.

It struck me as I was reading it that life was so much simpler back then. I remember my mother washing out the milk bottles (the two in the photo escaped as I found them while doing a litter pick!), using brown paper to cover school books, washing the nappies by hand and we walked or cycled to the shops. My first introduction to typing was on the typewriter in the photo above (that’s not that many years ago!!). I remember strapping it to my bicycle and cycling four miles to the classes and back home again.

Whoever originally wrote this piece was right – we probably didn’t consume nearly as much oil/gas/electricity back then. However, it wasn’t because we were being ‘green’, it was more because technology hadn’t advanced far enough yet. What do you think? Were we being ‘green’ back then or was it just a way to make ends meet?

Hydropower installation and restoration of Penllergare Valley Woods

Located on the northern fringe of Swansea, Penllergare Valley Woods was once a famous gentry estate and home to John Dillwyn Llewelyn, the notable 19-century horticulturalist, philanthropist and pioneering photographer. It is Llewelyn’s design, vision and influence behind the picturesque and romantic landscapes of the park.

For almost half a century Penllergare Valley Woods was neglected, vandalised and threatened by development and so the Penllergare Trust was formed in 2000 as an independent charity with the aim of restoring and regenerating the Grade II listed Penllergare Valley Woods to its former stunning glory. The leases of Valley Woods were finally assigned to the Trust on 26th April 2012, effectively securing them for public benefit until 2116 – that’s 104 years! This in turn initiated the award of £2.4m by the Heritage Lottery Fund through it’s Parks for People Programme to support the first phase of an ambitious £2.9m restoration scheme focussed on the upper end of the valley.

It’s a place where you can enjoy the sound of birds, delight in the profusion of wild flowers, discover evidence of exotic plantings and uncover for yourself the hidden features of a grand design. Wildlife research carried out by Swansea Council has found the estate is very significant for amphibians and acts as a “corridor” for animals to thrive and move about.

The restoration of Penllergare Valley Woods will provide an essential green space to relax, explore and have fun in as well as creating jobs and providing training opportunities for local people. The involvement of local volunteers was vital to the success of this project and it’s fantastic to see so many people  involved, learning new skills and playing their part in taking the local  heritage into the future.

The development of the hydropower scheme in Penllergare Valley Woods will generate sufficient power to meet the needs of the sites new visitor centre and excess sold to the National Grid, raising an expected £10,000 per year for the trust.

Lowering the Archimedean Screw into position

The Archimedean Screw with a length of 11m and a capacity of 2880 m3/h is situated next to the waterfall at Penllergare Valley Woods. The hydropower scheme was designed by Mannpower Consulting Ltd and the Archimedean Screw was manufactured by Dutch company Landustrie.

The enclosed compact design was the preferred design of screw for this particular site as the design minimises the installation cost and doesn’t intrude on the existing landscape.

The Archimedean Screw is placed into the bank side and sits at an angle that roughly matches the existing natural profile of the ground.  Three clear panels along the length of the screw will enable the functioning of the screw to be monitored and the workings demonstrated. It could therefore be used to educate the public about hydro electricity and alternative energy sources. Once in-situ most surrounding areas will be dressed with soil and stone and this will enable it to blend in with the surrounding area.

We are heading over to begin the commissioning of the scheme at the beginning of February. Since our arrival on site the newly built Llewelyn Bridge has been opened to the public.

On the 9th April the Penllergare Valley Woods Archimedean screw hydro generator was commissioned and handed over to the Penllergare Trust. Initially, the electricity generated will feed the coffee shop, woodland centre and the office cabin by the car park, thus reducing significantly the running costs. The Trust are negotiating with Ofgem and their electricity provider to buy surplus electricity from them by feeding it in to the National Grid. All of the income derived from this will be ploughed back into running and maintaining Penllergare Valley Woods for everyone to enjoy.

The commissioning of the Archimedean Screw was based on the partially de-silted lake configuration. It will need to be adjusted once the lake works have been completed later in the Summer. In the meantime the Trust plan to move soil, place stones and later, plant trees and shrubs around the works to better integrate it all into the landscape. Once this work has been completed, the area around the turbine will be open for people to take a look and to see the screw turning through the specially designed viewing panels in the top of the screw housing.
