Cambridge Folk Festival

Relationship with Energy Supplier is Key to Reduction

Cambridge Folk Festival has been running since 1965, it takes place in July and has a capacity of 14,000. The Festival is committed to reducing the environmental impact of the event and have found that a strong relationship with their energy supplier, Pearce Hire, is key to reduction.

Cambridge Folk Festival have worked with Pearce Hire for over 30 years and they have come to understand the Festival’s environmental and ethical values. They work closely with the festival’s Sustainability Coordinator and the Production Manager, to continually improve on energy efficiency, introduce new innovations and to meet the criteria for the A Greener Festival accreditations, which the festival holds.

As Pearce Hire provide both power and lighting, they can invest in more efficient lighting, knowing that their investment will be subsidized by the resulting reduction in generator size and fuel costs. They are also uniquely placed to identify where and when to turn on/off generators and therefore save fuel.

Over the years they have introduced a number of innovations in lighting: adding photocells sensors, manufactured in-house, to switch site lighting on and off at dawn and dusk as required, resulting in huge savings in energy use and cost. They also swapped power-hungry tungsten floodlights for LED and festoon lighting site-wide, and supplied LED fixtures for stage lighting — next year they are looking to invest in some new LED profile moving head fixtures.

Generators used onsite are all Euro Stage Three compliant — one of the most energy efficient, low emission generators you can get and they are arranged in an efficient system of many smaller generators rather than two big sets. The festival is also partially run off mains electricity, supplied through a green tariff, which saves 12-15,000 litres of diesel per event and makes a massive saving on the carbon footprint. Meter readings are taken every three hours during the festival so that the carbon footprint can be accurately calculated and the festival’s major impacts can be identified and improvements made where necessary.

The Festival encourages all staff and vendors to ‘switch off ’ when possible; punters are asked to reuse plastic cups to reduce litter and waste; backstage, water coolers are used instead of plastic bottles. The Festival commission wildlife investigations of the site and go to great lengths to protect local waterways, land and the biodiversity of the area from negative impacts of the event.

Over the last five years Cambridge Folk Festival have reduced their diesel usage by a third. These achievements are a testament to what can be achieved when supplier and festival teams bring mutual commitment and prioritise reducing their environmental impact.

Latitude, Leeds & Reading

Festival Republic: Energy Management at Reading, Leeds and Latitude Festivals.

Festival Republic is a leading UK music events producer with a portfolio of 19 music festivals across Europe, including Download, Latitude, V Festival, Reading, Leeds and Electric Picnic Festivals. More than half a million people attend the festivals they own and co-produce each year.

Festival Republic are committed to understanding and reducing the environmental impact of their festivals but this case study focuses on the challenges and successes of their commitment to reducing CO2 emissions from energy use at Leeds, Reading and Latitude.

Their sustainability policy includes using waste vegetable oil biodiesel to power the festivals’ generators. Between 2010 and 2011 they increased the amount of biodiesel used at Leeds from 18.5% to 24.5%, and at Reading from 12.5% to 18.2% in 2012. This commitment continues despite there being limited biodiesel supply in parts of the country, unpredictable price fluctuations, and a higher cost for sustainable biodiesel in comparison to regular diesel. They now aim for biofuel to make up 15% of the total fuel burned on site, in line with the Julies Bicycle benchmark, and are investigating into fuel efficiency measures to reduce the amount of fuel they use in the first instance.

Festival Republic requires their energy contractor to monitor generators and provide data on the actual fuel consumption after the festival. Based on the data collected, Festival Republic is working to reduce the size and/or number of generators to better match their energy needs and be more efficient about their fuel use. In 2015 Leeds and Latitude Festival were able to reduce the overall size of the generators compared to 2014 and this was achieved even though there was an increase in the festivals infrastructure. 2016 is the fourth year of data they have collected and are working closely with their power suppliers to see if this can be used to make further energy efficiency savings.

In 2015 Festival Republic explored alternative and new energy technologies such as hybrid generators and solar power. They also hired solar powered batteries that can be linked to generators to reduce the generator run-time. After a trial at Latitude, one of the power contractors has invested in a number of these batteries tailored to their technical needs to add to their own fleet, showing that Festival Republic’s dedication is indirectly supporting fuel efficiency in the broader events industry. Combining the two different technologies has been challenging, requiring training for the engineers in the field and dedication from the teams. The initiative is not yet financially viable, but Festival Republic continues to invest to support this kind of knowledge exchange between solar power and generator companies.

Festival Republic works with their contractors to reduce energy demand through specifying more energy efficient technologies; for example, in 2012, Colour Sound Experiment, one of their lighting and visuals rental companies, invested in 1.5 km of LED festoon lighting in response to demand from Reading Festival. The Festival Republic technical production teams work with their audio, video, and sound companies to improve communication around power specs and energy requirements to encourage broader industry conversation about ‘what’s actually needed’ at festivals.

At Latitude in 2015, the audience was engaged around the topic of energy and sustainability through a partnership with De Montfort University’s ‘Face your Elephant’ project. The audience were also physically acquainted with energy awareness through cycle-powered phone charging stations to promote renewable energy in a creative way.

Since 2009, Leeds and Reading festivals have reduced their total carbon emissions significantly, by more than 20% per audience day. In 2015, Latitude and Leeds were awarded a Creative Industry Green rating of four stars and Reading has achieved three stars since 2013. 2016 was the first year in which Download and V Festival were assessed and at the time of writing this case study the results are awaited.

The Green Gathering

Engaging the community in using renewables

The Green Gathering is a festival with an environmental and social justice focus; it has workshops and talks on permaculture, politics, ecology and crafts, as well as art, live music and spoken word performances. It currently has a capacity of 5,000 and takes place in Chepstow, Monmouthshire.

The Green Gathering is proudly run on 100% renewable energy solutions. Throughout the years the organisers have faced and overcome many challenges in producing a festival with no generators. Many of the solutions to problems in this area have come from successfully engaging their community of audience, traders and suppliers in a shared commitment to operating sustainably.

To providing lighting for the festival without using generators they switched to 100% LED lighting throughout, which was a bigger challenge that it sounds due to an initial lack of suppliers of relevant products. Over the years they have engaged suppliers to build up a list of companies who can step in to provide the right products in the right quantities onsite.

Wheelchair and mobility scooter charging using renewable technology was a challenge to overcome as The Green Gathering’s Assisted Access camping area filled up and demand grew. The festival implemented a number of solutions in 2014, ranging from bringing in extra solar power providers to communicating with the audience to inform them to arrive with batteries and spares fully charged, and by stipulating charging times. These measures were so successful that in 2015, The Green Gathering was able to extend its Assisted Access area further with confidence that the audience’s energy needs could be catered for.

“Informing and engaging customers is vital to keeping them on board and positive about running on renewables, especially if being ‘green’ means they can’t have exactly what they want when they want it!”

The Green Gathering requires traders to be 100% renewably powered, ethical and offer a quality product or menu. For traders who meet these criteria but usually run on mains electric, advice and information is on offer to help them go ‘off grid’. In some cases traders can be linked up with the festival’s regular renewable power providers who may, for a small charge (or free meals!) be able to provide the power needed. The festival’s Green Markets coordinator also provides information to cafes about low-energy equipment and menus if they are keen to make the switch to renewables.

“The Green Gathering community has a number of solar and LED experts who can advise traders to help them trade off grid not just for this event but at all events, so that everyone benefits in the longer term. It’s largely about engaging with the traders.”

The people who come together to create and co-ordinate the festival have built up rich resources of knowledge and are keen to share their skills and experience to benefit not only the festival but also the wider world, through empowering people to be environmentally responsible and resilient.

Many thanks to The Green Gathering for providing the information for this case study.

Boom Festival

An Innovative Off-grid Festival

Boom is a biannual electronic and world music festival based in Portugal, with an audience capacity of 33,333. Boom Festival began in 1997 as a psychedelic trance music festival, but has now diversified to include a range of DJs, live music and visual arts performances.

Boom is powered by a mix of off-grid photovoltaic panels, diesel generators and a 100kW waste vegetable oil (WVO) generator. Boom has won the Greener Festival Excellence Award four times (2008, 2010, 2012 & 2014), and in 2010 won the YOUROPE Green & Clean Festival of the Year; which led to Boom becoming a participant in the United Nations Music & Environment Initiative.

As well as using renewable and energy efficient technology, Boom Festival is committed to the energy management practices of conducting energy audits and power demand assessments, before and during the festival, and continually auditing and reviewing generator sizes. Boom has a sustainability director who oversees an off-grid project manager and several electrical managers. Efficiencies in energy planning and generation meant they used 40% less energy in 2014 compared to the 2012 edition of the festival. In the 2016 edition, they have almost doubled the lighted areas (using predominantly LEDs), but thanks to efficiency measures their lighting energy consumption will stay the same as 2014.

In 2008 Boom collected and re-used 45,000 litres of WVO, which was used to feed their generator as well as three of their fleet vehicles. Their pioneering Your Oil Is Music project — through which waste oil is collected from local towns — ensures a local supply of renewable energy as well as engagement with the local community.

Boom festival uses 40 kWh of solar energy, which is produced onsite, and is in the process of transitioning from diesel to even more off-grid photovoltaic energy. Their largest photovoltaic array comprises 18 panels, all following the tilt of the sun, and producing 13kw per hour per day. ‘Boom Off-Grid’ is a project that was developed in 2012, in partnership with the local organisation BioEspaço, to increase Boom’s energy efficiency: it includes integrating technologies such as solar irrigation systems, LED lighting and inverters.

The area in which Boom takes place, known as Boomland, is home to around 12 long-term residents and the onsite renewable technology is a permanent feature in the community. The residents spend the 23 months between festivals living entirely on renewables, and creating an energy surplus for the next festival.

100% of all water used at Boom is biologically treated and reused onsite for agricultural irrigation. In 2016, Boom’s permanent onsite gardens will use 25% recycled water and composted organic materials. The festival is commissioning 350 dry-toilet units that are fitted with bio-filters meaning they produce no waste.

The whole of Boomland is under a Holistic Management plan that integrates the presence of the public as a technical positive impact in the local soil biota. Besides the people, domestic animals such as sheep and cattle are used to increase soil fertility and forest regeneration. In 2015, 600 new trees were planted in Boomland and many thousands more in partnership with Ecocentro Ipec in Brazil.

Øya

Large-scale festival powered by hydroelectricity from the grid

Øya is a music festival in Norway that has been running since 1999. For the last 2 years it has taken place in Tøyenparken, a green space in the city centre of Oslo and attracts approximately 70,000 audience members over four days.

Øya’s aims to be a pioneer of green events: leading by example and inspiring fellow promoters, businesses and audience members. Øya embeds sustainable and resource-efficient thinking across all of its operational activities, including: power, waste, food, transport, promotional materials and even toilet paper. Øya has received a multitude of awards, including two ‘Green’N’Clean’ awards, and ‘A Greener Festival’ award for the previous six years. Every year over 90% of the food served at the festival is organic. Local produce is chosen when possible, and is preferably bought directly from the local farmers. There are always vegan or vegetarian alternatives.

In 2010, Øya switched from diesel generators to exclusively grid/mains power, which is 98% renewable-derived (mainly through Norway’s hydroelectricity generation) and has removed virtually all on-site emissions. The switch was implemented gradually, with a mix of generators and mains power in 2009. It required a major investment in new infrastructure for the festival, which the Øya was able to undertake through a partnership with the municipality of Oslo and their main sponsor at the time, Hafslund (a Norwegian power company who continue to supply the festival through the grid today).

Øya also made significant year-on-year electricity consumption reductions including a 9% reduction between 2011 and 2012, and a further 22% between 2012 and 2013. These energy reductions are the result of a variety of efficiency projects and awareness-raising campaigns with staff, volunteers and external vendors. Øya has integrated energy efficiency within the festival’s technical operations by rationalising the size of light and sound mixing tables, and using LED lighting and LED based strobe lights wherever possible.

In cooperation with Hjellnes Consult (consulting firm) and Nature and Youth (Øya’s main environmental partner), Øya conducts energy-awareness tours during the course of the festival. The main office in which Øya’s staff work throughout the year also carries ‘green office’ certification.

Thanks to the help of volunteers from Nature and Youth, who sort through every single bag of waste from the festival by hand, they are able to recycle about 70% of the waste from the festival into 15 different fractions each year. This saves the environment from CO2 emissions equivalent to what 35,000 cars emit every year.

Many thanks to Oya for the information for this case study.

Croissant Neuf Summer Party

Running a main stage with less power than a domestic hairdyer

Croissant Neuf Summer Party uses solar power instead of diesel generators on site to power the stages and lights. They have never used anything but solar and wind generators. This saves over 1.5 tonnes of CO2 for the festival. The LED lighting system in the Big Top uses less power than an average household TV. The P.A. system in the big top uses less power than a hair dryer but still has a sound output equivalent to a 10KW P.A.

All the caterers and market traders on site use renewable energy. The bar uses hand pumps and all their lighting is low energy LEDs, powered by dedicated solar panels. The commission of an Environmental Audit of activities in 2010 showed that festival goers at Croissant Neuf Summer Party generated on average less than 50% of the CO2 they would otherwise generated if they’d stayed at home and had a normal weekend.

Croissant Neuf is powered 100% by renewable energy due to a conscious decision to buy solar panels and wind turbines instead of diesel generators when the organisers, being keen environmentalists, endeavoured to expand their festival and cafe that originated in 1986.

The original Croissant Neuf consequently gave birth to the Green Roadshow- a travelling environmental education centre with the circus big top at its focal point. All electrical appliances were run entirely on power solar and wind power, including the big top lights and PA and even the hairdryers and laptops in the living vans. This dedication ensured continued pursuit and commitment to renewable technology, conservation, battery powered transport, sustainable living and woodland management. Whilst touring as The Green Roadshow, Croissant Neuf continued to appear as a renewably powered venue at Glastonbury and at other festivals such as the Big Green Gathering.

A massive solar generating unit capable of creating enough power to drive a 10kilowatt P.A system was installed at the turn of the millennium, as music became the main focus of Croissant Neuf. This masterpiece of modern technological engineering was titled The Solar System. Within a few years Croissant Neuf had created the first fully functioning solar rig of its kind that could deliver perfect sound for anything from solo artists through to a 40 person gospel choir. Each year Croissant Neuf Summer Party attempts to improve its sustainability.

We Love Green

Winner of the Green Operations Europe 2012 Award 100% renewable

We Love Green won the ‘Green Oscar’ of the European Festival industry in 2012. They designed a sustainable festival at the outset, and their attention to detail is exceptional. Amongst other achievements, they managed the event on 100% renewable sources., including stages, site services, catering and interactive art.

Firefly supplied the power, providing their Youpower playground and software for the children’s area, featuring 6 bikes with PedGens, a WhirlyGen roundabout, Teedlegen see-saw and LumberGens (the latest addition to their Kinectrics range of products). Their software shows just how much energy is being generated by these playground toys in real time. This is an excellent way of showcasing innovative green products while providing a fun interactive way of educating about the possibilities of clean tech.

They also provide the power for the lighting of the main stage. This is powered by a 45kVA solar rig consisting of 9 Cygnus solar generators and 14Fold Array portable solar PV panel arrays. This allowed for substantial carbon savings for the festival and provided silent, reliable power over the three day event.

The Electric Hotel

Charging ahead! A mini, mobile phone charging power station.

Brainchild of artist Sebastian Fleiter it is a shining example of audience engagement in renewable energy provision. It offers an interactive service for charging phones in the form of pedal power for a free, quick, and fun energy supply at festivals. The brightly polished 1960s chrome camper van also has solar cells, wind turbines and a pump storage hydro power unit which allows it to run 400 mobile phone charging points with lockers that can be availed of for a small fee, allowing them to charge over 3000 phones a day.

Technical challenges in the first year of this innovative and ambitious non-profit business included the underestimation of the requirements for mobile phone charging. They found that standards for phones are not as common as you might think, and there are many different socket types.

To overcome this difficulty around half of all charging points can be used with any model, while the other half have adapters for mobile phones with unique sockets. This service has ended up being a pragmatic idea for providing renewable electricity to festival goers, originating from an idea incorporating the worlds of art and technology.
Currently, new power generators are being developed for The Electric Hotel, and they have received funding from the European Union EFRE programme, as well as various awards for their endeavours.

The Electric Hotel not only provides an affordable and necessary renewable energy powered service, but simultaneously informs and engages festival goers in alternative energy procurement.
