I recently worked with the team behind King’s sustainability module on the section on energy. 

Side note: If you haven’t heard of it, where have you been? For those of you that haven’t seen it, it’s a great open-access resource that brings interdisciplinary knowledge from both students and staff. Don’t be put off if you don’t have any understanding of sustainability, the module aims to provide something for everyone. So, even if you have a strong knowledge base, it covers a lot of areas; you’re guaranteed to learn something new. Check it out here.

Anyway, as part of my research for it, I learned that in the UK (as of December 2020), renewable production generated 40.2% of total electricity produced in the UK; around 6% of total UK energy usage. This last number surprised me. The 2020s are supposed to be the decade of green action with the UK having a strategy in place for decarbonising all sectors of the economy to meet a net-zero target by 2050. So it made me wonder: why is there a lack of renewable energy use in the UK? Well, here’s what I found out:

First, the UK has a regressive approach to funding low-carbon transitions. The energy is currently being funded by levies on the energy bills of consumers. As it stands, 27.9% of energy bills go towards the construction and maintenance of energy infrastructure. Consequently, those who spend more on energy bills relative to their income contribute more to the low-carbon transition. Let me be clear, as I’ve expressed in another blog post, this has not caused the current energy price crisis. But, as prices rise with the increased cost of living, if these bills cannot be met, the transition will be held up. There’s nothing just about that. 

As a result, the UK sector doesn’t receive enough support to produce and manage energy. According to data from the Office of National Statistics released on the week of the 14th of February, the UK’s low-carbon and renewable energy economy has failed to grow since 2014. In the same period, employment in areas such as manufacturing low-carbon technology, energy supply and construction has actually dropped by 28,000 and is currently roughly 207,800. Particularly concerning is that areas such as onshore wind and solar energy, which are essential components of a low-carbon energy mix, have been hit the hardest. It would be easy to place blame at the door of Coronavirus, but it looks like businesses in these areas were struggling in 2019. Even in relation to offshore wind, the UK’s flagship renewable source, energy production isn’t as high as might be hoped. Despite historically high energy output from wind farms in Scotland, the UK generates less than its counterparts in Europe.

Another reason that the UK is struggling to increase renewable energy’s contribution is storage. With much renewable energy being reliant on weather conditions, inter-seasonal storage remains a core challenge for the industry (and not just the UK). As such, there needs to be a lot of investment in energy storage. Lithium-ion batteries are expected to dominate the storage boom. On this front, the UK has started to invest. It has been recently announced that one of Europe’s largest battery storage facilities is set to be built in Scotland and is due to be operational in 2024. The Green Battery Complex will comprise two 400 MW facilities, each providing 800 MWhrs of energy storage capacity. However, capacity is measured in hours instead of days or weeks. As a result, looking forward, the UK would be wise to invest in other energy technologies such as green hydrogen, ‘gravity’ storage, and ‘cryogenic’ batteries.

In terms of other things the UK must consider when looking to the future, it must place localism at its heart, promoting community energy developments and supporting households. This is both in terms of reducing energy waste such as insulation as well as initiatives like solar panels that reduce the need for grid-supplied energy. 

Correction from previous blog post.

In a blog post from 2021, titled “King’s Energy: The Noor Ouarzazate Solar Complex”, the author outlined that it would take 116.5 Noor’s to supply the world with renewable energy based on 2019 demand. The actual number is 116.

Thank you to Assoc. Prof. Johan Montelius from Royal Institute of Technology (KTH) for identifying this and bringing it to our attention.

He is a strong believer in a just and equitable clean energy transition. He is excited to write about this as well as more King’s-related energy topics for the team’s blog. He also wants to help develop toolbox talks for King’s staff and teams that centre on how to use energy sustainably.

On the 24th of February, Russian troops initiated a full-scale invasion of Ukraine. This attack has led to widespread condemnation of Putin and his crony regime. It has already caused huge amounts of deaths – much of which has been civilian – displacement and destruction of property.

In response, increasing numbers of sanctions have rightly been placed on Russia to try to undermine its war efforts. These have included excluding some banks from the SWIFT payment system and the seizing of oligarchs’ assets, such as massive yachts. One surprise reaction to Russia’s declaration of war was the decision by the new German chancellor, Olaf Scholz, to halt the Nord Stream 2 pipeline. For those of you that want to impress your friends with knowledge about Nord Stream 2, it is an $11billion undersea pipeline that would allow for the direct transportation of Natural Gas from Russia to Northern Germany. While the pipeline itself had been completed, it was not active. 

It was a surprising move as Scholz had avoided saying that this was likely until the decision was announced. Yet, while it is commendable and welcome, it isn’t an end to Russian gas imports. Indeed, the activation of the pipeline has not been ruled out, it is just suspended for now. In the meantime, the EU and the UK continue to send millions of pounds a day for natural gas, which is being used to fund the invasion of Ukraine.

The war has exposed the unfortunate position that Europe finds itself in; it is dependent on Russia for the natural resources, oil and gas, that keep the lights and heating on. Now the price of these natural resources is not just the environmental damage they cause and the increased cost of living they are fuelling (as if these weren’t bad enough); they are also funding a literal war in Europe.  

There have been calls that the right response is to resume fracking with “vigour”. What a benefit of Brexit that would be; increased risk of earthquakes and flammable water! Instead, now, more than ever feels like the right time to urgently move away from these sources of energy. What’s the alternative? Well, renewable energy. Of course! It’s encouraging to see that Germany has already started down this path. Shortly after announcing the halt to Nord Stream 2, Germany outlined that it is bringing its target of 100% energy from renewable sources forward by 15 years (from 2050 to 2035). This is possibly a challenging commitment considering that it is already set to exit nuclear power in 2022 and coal-fired power by 2030. But, it is also essential for the environment, Germany’s economy and national security.

Other countries would be wise to follow suit. Here in Britain, we are set to import more than £2bn worth of Russian liquified natural gas imports this year, despite the best efforts of dockers from Kent. The recent order to ban ‘all ships with any Russian connection whatsoever’ doesn’t cover the origin of the cargo, including fossil fuels that may have been sourced from Russia. This approach must change. In dropping Russian oil and gas, the UK government must look at renewable energy sources to replace them. It can follow the example set by the Netherlands which was able to cut gas demand by 22% in two years with renewables. At the same time, the UK must roll out measures to insulate homes, install heat pumps and reduce the cost of renewable energy.
