Energy supply: Experiences of traditional and environmentally conscious growth models

This September, I travelled to Tohoku University, Japan, to take part in the RENKEI summer school programme on the theme of Energy Supply within Traditional and Environmentally Conscious Growth Models. RENKEI is a Japan-UK collaboration and six universities from each country participate in pilot projects in three key areas: technology and knowledge exchange with industry, student mobility, and universities’ social engagement. Early career researchers, PhD students and taught postgraduates work together within a supported framework to develop critical skills in a dynamic environment.

In my role of Education for Sustainable Development (ESD) Coordinator, I was interested to see the teaching and learning applications of this theme in an interdisciplinary context. I am forever indebted to the University of Bristol for supporting this extraordinary opportunity (thanks to PVC Nick Lieven for funding provided and for accepting my application).

Fieldtrips were an essential component of the experience. At the Sendai municipal incinerator plant we learned how household waste provided energy for the city. I was surprised to hear that the household waste in Sendai is not segregated into recycling and non-recycling. When asked, the lead incinerator engineer commented that this situation was not ideal, but until recycling became widespread, incineration provided an energy benefit to the waste problem. The Miyagi Province Toyota Factory demonstrated how surplus heated water from the manufacturing process could be channelled into community-run glass houses to support local agricultural production. Factory workers were also encouraged to explore sustainable projects on the company’s grounds, for example, planting tree grooves that would serve as a relaxing space for future generations of workers. The implication was that the children of the factory workers would continue to work for Toyota and Toyota would continue to support the community.

The last fieldtrip of the week was to tsunami-devastated regions to the north of Sendai. The ravaged coastline and high death-toll (estimated in the region of 16,000) three and a half years later was still in the process of recovery. Plant regrowth disguised much of the damage. Construction workers showed us models and videos of the reconstruction plans, including: moving rail lines; flattening hill tops; building sea barriers; and rehousing thousands of displaced families. A boat-ride along the coast showed how the fishing industry was slowly recovering, while the tourism industry, once flourishing, was now in shambles. Over 3,300 locals are still homeless, living in pre-fabricated buildings that are quickly disintegrating. While the press criticises the speed of rebuilding efforts, speaking to the construction team showed that every effort was being made but the scale of the work was a huge undertaking.

Talks and workshops engaged with the theme of energy supply, focusing on applying interdisciplinary knowledge to create "Sustainable City" solutions. Prof. Nakata of Tohoku University acted as our lead academic for the week.

Prof. Bahaj (Southampton) was the first of the week’s speakers. He explored contrasting ideas of refurbishment of cities vs green fields, the consumer society vs equity, and that city planners must consider the ecological footprint, not just carbon. A basic tenant he offered was “everything is driven by money”.  Prof. Nakata (Tohoku) wanted us to think about cities, towns, everything, not just government systems. He noted the importance of economics, resource constraints, environmental constraints, technological systems, and energy system components. The idea of community energy systems that are small scale and less dense in their demand was proposed, summarised as “Global + Local = Glocal”. He also highlighted how a low carbon society leads to sustainable and resilient business.

Mr. Suzuki (Fukushima Prefecture Government, business creation division) spoke on the importance of collaboration, including local company support, collaborative R&D, university support, and human public relations.  Mr. Tsuruoka (HOPE - Higashimatsushima Organisation for Progress & Economy, Education and Energy) startled the room with the shocking facts surrounding the tsunami disaster. Fishing was reduced to 60% of before, tourism was down to a third of pre-disaster, 65% of the city went underwater, resulting in a loss of life of 3% of the population. Simulations of potential tsunami damage were twenty times smaller than reality, meaning that there was a lack of preparation and proper evacuation when alarms were raised.

Discussions continued at break times.

Dr. Kunimitstu (NARO - National Agricultural & Food Research Organisation) introduced us to the Japanese concept of Hosaku Binbou, which is the impoverishment of farmers because of a bumper harvest. This relates to market equilibrium and the optimisation of producers. Prof. Shukuya (Tokyo City University) explained the low energy system design and its application to sustainable city design. Dr. Barret (United Nations University) discussed energy equity on a global scale. Prof. Kurokawa (Tokyo Institute of Technology) showed how 10 countries are using 50% of world's capacity for carbon and what this means for future sustainability planning. Shuichi Ashina (National Institute for Environmental Studies) discussed planning for future energy demands, adaptation models, and low carbon society scenarios.

The majority of students were from Engineering, with a handful from the Sciences, while I was the only collaborator from an Arts background (Archaeology). This difference was particularly noticeable during questions and discussions, and within the group work sessions. Many students commented on how the Arts approach to problem solving and systems thinking was quite different, but proved beneficial to broadening their perspective.

As I stated, my aim was to see what teaching and learning elements I could take from the experience, and one that stood out was how interdisciplinary approaches to problem solving could be developed much further. In the future, I hope that RENKEI will open itself more to contributions from the Arts and other subject areas to encourage broader views.

The Diamond Battery – your ideas for future energy generation

On Friday 25th November, at the Cabot Institute Annual Lecture, a new energy technology was unveiled that uses diamonds to generate electricity from nuclear waste. Researchers at the University of Bristol, led by Prof. Tom Scott, have created a prototype battery that incorporates radioactive Nickel-63 into a diamond, which is then able to generate a small electrical current.
Details of this technology can be found in our official press release here: http://www.bristol.ac.uk/news/2016/november/diamond-power.html.
Despite the low power of the batteries (relative to current technologies), they could have an exceptionally long lifespan, taking 5730 years to reach 50% battery power. Because of this, Professor Tom Scott explains:
“We envision these batteries to be used in situations where it is not feasible to charge or replace conventional batteries. Obvious applications would be in low-power electrical devices where long life of the energy source is needed, such as pacemakers, satellite…

A response to Trump's withdrawal from the Paris Agreement

The decision by President Trump to withdraw from the Paris Agreement on Climate Change puts the United States at odds with both science and global geopolitical norms.  The fundamentals of climate change remain unambiguous: greenhouse gas concentrations are increasing, they are increasing because of human action, the increase will cause warming, and that warming creates risks of extreme weather, food crises and sea level rise. That does not mean that scientists can predict all of the consequences of global warming, much work needs to be done, but the risks are both profound and clear. Nor do we know what the best solutions will be - there is need for a robust debate about the nature, fairness and efficacy of different decarbonisation policies and technologies as well as the balance of responsibility; the Paris Agreement, despite its faults with respect to obligation and enforcement, allowed great flexibility in that regard, which is why nearly every nation on Earth is a signatory.

Age of the Anthropocene

“We’ve killed off the dodo, released unprecedented levels of carbon dioxide into the atmosphere, and raised sea levels: welcome to the Anthropocene, the geological age in which humankind has permanently left our mark on the planet.”
This was the description I gave to my new unit ‘The Age of the Anthropocene’, hoping to catch the attention of second year students keen to explore the impact and meaning of global environmental change. It worked: students from History, English Literature, Religion and Theology, Philosophy, Ancient History, and Study Abroad students joined me this autumn to explore how the notion of the ‘Anthropocene’ has gained traction as a definition of time that recognises the unprecedented Earth-altering impact of the human species. We engaged with debates among scientists and humanities scholars over the concept, while also exploring how it has captured popular and scholarly imagination. 
One of the activities that I looked forward to was holding an inaugural Bristol ‘…
