Energy Harvesting, Internet of Things and Sustainability: A Fascinating Trio

Energy Harvesting, Internet of Things and Sustainability: A Fascinating Trio

by Lethy Krishnan Jagadamma

The energy trilemma describes the difficulty in achieving a coherent balance of clean, affordable, and secure energy. Improvements in one factor in the triangle distorts the other components. In this blog post, I explore how ‘smart technologies’, connected by the internet and powered by new ambient energy harvesting devices, can be vital to overcoming the energy trilemma and to achieving energy sustainability.

Youth and Climate with Isabella Cuervo-Lorens and Georgina Steel

Youth and Climate with Isabella Cuervo-Lorens and Georgina Steel

Host James is joined by Dr Emilka Skrzypek (St Andrews) for a special youth-focused episode of the All About Energy podcast. Our hosts welcome two guests into the virtual studio – the winner and runner-up of the Centre for Energy Ethics’ 3MPlanet competition: Isabella Cuervo-Lorens and Georgina Steel. Our guests reflect on their journeys into the worlds of sustainability and climate change and the importance of the youth voice.

Climate adaptation and mitigation initiatives have driven up demand for rare minerals. Over 3 billion tons of rare minerals will be needed to achieve the global goal of reducing emissions to net-zero. A key site of extraction of these minerals is Sub-Saharan Africa. Will these regions acquire a share in this mineral boom or will the historical exploitation of these communities continue under the guise of supporting the ‘Green Transition’?

Understanding Energy: Reclaiming the air through sustainable aviation

Understanding Energy: Reclaiming the air through sustainable aviation

by Andreas Bock Michelsen

Flying is a convenient mode of transport, but it is also a major contributor to carbon dioxide emissions. The question is, how could we make airplanes run on renewable energy? By considering the basic physics of the problem, in particular the concepts of energy density and combustion, we see what makes jet fuel such a brilliant fuel energy-wise, why batteries are not a likely alternative, and why hydrogen might be the key to sustainable aviation.

Is it really renewable, for peat’s sake?

Is it really renewable, for peat’s sake?

During the ‘Energy Debate’ panel hosted on Friday 13 November as part of Energy Ethics 2020, it became clear that the challenges of powering the world on renewable technologies were as palpable as the need to overcome them in order to reduce our reliance on fossil fuels; and reducing this reliance is imperative if we are to limit the impacts of ongoing climate change.
