An integrated energy system has large potential to revolutionise our energy economy. If the UK is to achieve Net Zero by 2050, it requires little less than transformation of our current energy system in becoming smarter, cleaner, affordable and low-carbon. In light of the recent power cut in England and Wales, integration could also help make the energy system more resilient to faults and prevent failures.
In the final podcast of the Science Perspective series from #awriterinthelab, we speak with researchers in key areas of the integrated energy revolution from electrical, cyber security and transport engineers, to material scientists and industry practitioners innovating the future of solar PV, EVs, energy storage and hydrogen for an integrated energy system. Enjoy.
But there are of course exceptions and likely many more are growing in response to planetary pressures. One of them is Sea Pigs based in Newcastle who make footwear designed to be recycled. I actually ran into their CEO once on Northumberland Street while giving a public survey on climate change, so thought it worth mentioning them.
Textiles as I learned at the Ending Waste event at Newcastle Helix, have a high carbon footprint, one that is easily ignored by consumers (I have many cloth bags too, just remember to use them for shopping at least 300 times). To really value materials, we need to move to something better – use less and do more with what we have.
A circular economy begins and ends with resource instead of waste, in fact, it doesn’t really end at all. It valorises products derived from natural resources that we otherwise throw away, and which inevitably clog the ecological systems we depend upon for survival. Cities throughout the world are doing more to embrace or at least help along mainly linear modes of material disposal and recycling, shaping them into circular ones.

There are between 25,000 to 30,000 bee species living today that affect 35% of global agricultural land. Therefore, we need an international understanding of honeybee health, both in terms of the pathogens and environmental factors that affect them, and what beekeepers can do to improve the health and ecological status of bees.
Bees are threatened by a range of factors: from diseases to pesticides. Being an especially sensitive species of insect, it is no surprise that climate change also affects bees. The primary culprits threatening bee survival include habitat loss, pollution, pesticides and pathogens.
Research on beekeeper education and disease control published in Plos One, identified key risk factors that lead to the death of honeybee colonies. It was the first surveillance programme done on randomly selected participants and used standardised methods to monitor the health of the honeybee colony, pests, diseases and management practices across 17 European countries from 2012-14.
This week marks two special days for environmental sustainability: International Day for Biological Diversity and World Bee Day. While symbolic in scope, the importance of having days dedicated to thought, speech and action for protecting and increasing biodiversity and bees on this planet deserves recognition.
In this short post I want to flag up a video produced at Newcastle University with two brilliant researchers in biology and ecology: Dr Louise Mair and Dr Rike Bolam. They answer a series of questions from young people about animals and biodiversity more generally.
“The health of ecosystems on which we and all other species depend is deteriorating more rapidly than ever. We are eroding the very foundations of our economies, livelihoods, food security, health and quality of life worldwide,” Robert Watson, Chair of the IPBES
There is dire need to prevent the planet’s numerous flora and fauna from going extinct, including the many species that humans depend on for survival.
A recent report on the state of biodiversity from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) makes clear that nothing less than transformation must happen for humans continues to live on this planet much longer.
Known long before the advent of science, the fate of the human species interconnects with its neighbouring species on the tree of life.
Species’ future existence affects and in many ways determines our own. As humans, the most dominant species on Earth, we fancy ourselves as makers of our own destiny, but time to conserve our biotic lifeline is running out.
Plants provide the air we breathe and the nutrients we consume for survival. They capture and store the solar energy that our bodies cannot absorb directly. Insects in turn pollinate that plants that we eat. Similarly, the animals of the land and the sea that we use as a food source, if they were to come under threat, would place our own species in quite a precarious position.

If cities are to overcome the numerous challenges they are currently facing, including disasters, then it requires an array of sustainable techniques, methods and approaches for managing them. Cities are robust, often resilient but also fragile in the wake of perplexing environmental problems, such as climate change.
To clarify things a bit – hazards themselves are not disasters until they harm or eliminate life. A large-scale asteroid impact is most certainly a hazard but it will not be a disaster unless it harms life or damages the processes that support it. Earthquakes and flood hazards may be potentially disastrous but only in reference to the living things they are at risk of destroying.
The good news about disasters is that while they are not always preventable, it is possible to reduce their impacts through human means. In this geological epoch, climate change will persist regardless of human intervention, but its future impacts remain an open question – and humans have a strong role to play.
If you’re an academic researcher, and new to the SDGs, one of the things you should know about them is that they are interconnected – each goal relates to, influences and affects the other goals.
There will always be specific goals that an individual or organisation may focus on but this doesn’t mean the others aren’t relevant to your work; indeed the framework is broad enough to enable achieving targets for different goals together. For example, while you thought you were working on clean water and sanitation, you may not have realised that you’re also helping to achieve gender equality.
If you do research or other relevant work to goal 3 – Good Health and Well-Being, likely it will have implications for other goals such as goal 1 – No Poverty and goal 2 – Zero Hunger.
If your research is in energy, which pertains to goal 7 – Affordable and Clean Energy, then it will likely also be relevant to goal 13 – Climate Action and goal 14 – Life Below Water. Clean energy results in decreased greenhouse gas emissions for mitigating climate change, reducing ocean acidification, and energy affordability connects to goal 1 – No Poverty. Got it? Continue reading How to start interacting with the SDGs→
While water is a human right according to the United Nations, for everyone to have access to safe, potable drinking water and adequate sanitation requires significant advancement in water infrastructure, governance and education.
The GCRF Water Security Hub led by Newcastle University makes possible the collaborations needed to address water security in the developing world in a holistic way. I had the pleasure of speaking with some of the key researchers in the Hub from Newcastle in engineering and the social sciences.
In Part 2 of this episode of the Science Perspective podcast they explain the importance of water security, and how the Hub is working with multiple stakeholders to achieve SDG 6: Clean Water and Sanitation.
Looking to the near future — 2019 — there are four topics, four ideas I wish to highlight that could revolutionise not only how we tackle climate change, but many other global challenges the world is facing for sustainable development.
Revolutionise the energy system
Make circular economy a reality
Clean water and sanitation infrastructure for all
Spread electric vehicles
It’s a simple yet powerful (no pun intended) scientific fact that energy underlies everything. If we didn’t have it we wouldn’t exist and without the concept our lives would be radically different from what they are today. But let’s keep it to things like electricity and heat for the moment.
We need to generate more of them and use what we have more wisely, but the energy dense yet carbon heavy materials we’ve relied on since prior to the industrial revolution are a no go for the future. Embarrassingly, they’re on the rise despite progress made in renewables and decarbonisation.
Beyond emissions there were already in place good reasons NOT to burn fossil fuels. Remember acid rain? How about air pollution? Which cities finally seem to be paying attention to again because people are dropping like flies because of air contamination. Did you know that communities downwind of coal fired power stations are more likely to have children with birth defects? How about the impacts coal has on landscapes, water and air, all resources we cannot live without?
Humans and animals share a deep relationship going back to early homo sapiens. With the exception of pets, in many cases we eat each other, but since humans have dominated the planet — normally we eat them. This has not been more the case than in livestock farming where animals are raised for food and are depended on for survival, not only for nutrition, but people’s livelihoods.
Many of the farms in the UK produce cattle and sheep for food. Endemic disease in livestock is a major global challenge, and could likely continue in future if something isn’t done to prevent livestock disease from growing and spreading in the first place.
Whether livestock disease becomes a problem largely depends upon the practices of farmers and their advisers. Not all farming systems are the same and many of them have a history that goes back a long time. This means solving the problem of disease may not be solely down to applying the ‘right’ scientific or technological solution.
