‘Renewable, electric, digital’: the Fourth Industrial Revolution

Portfolio Manager and Head of Global Sustainable Equities Hamish Chamberlayne explores the changes ahead as we enter a decade of transformation and explains the importance of digitalisation, electrification and decarbonisation.

Synchronised investment boom into clean technologies

 
This year, the world’s most influential governments have made ambitious commitments to tackle climate change head on. In April 2021, 40 world leaders convened virtually to address the climate crisis at the Leaders Summit on Climate.

The White House stated its aim to reduce US emissions by 50% to 52% by 2030 based on 2005 levels and China premier Xi Jinping announced intentions to phase out coal use from 2026. Meanwhile, the UK government announced the world’s most ambitious climate change target – to cut emissions by 78% by 2035 compared to 1990 levels.

The UK’s sixth carbon budget is set to include international aviation and shipping emissions and would bring the UK more than three-quarters of the way to net zero by 2050. Today, we are pleased to see much greater global political harmony on the climate agenda. The stars are aligning for what we believe will be a globally synchronised investment boom into clean technologies.

So, what do these climate commitments mean for the fossil fuel economy? In order to align with the 1.5^oC climate limit, we will need multiple solutions to address the multiple sectors and industries involved. Countries must increase electricity share of the primary energy mix from 20% to 50% over the next few decades.

The US has set out material provisions to electrify a portion of the school bus fleet, retrofit buildings to higher environmental standards, reduce the use of coal and gas generation, and invest in the country’s electric and renewable energy infrastructure. The UK, meanwhile, has banned the sale of diesel and petrol cars by 2030 and announced a £20m funding pot for electric vehicles.

A decade of transformational change

 
Electrification of the global automotive fleet is one area that we are particularly excited about. As battery and computing technology continue to improve and associated costs decrease, we expect to see mass production and adoption of electric vehicles.

This is often referred to as the S-curve. When plotted on a chart, the S-curve illustrates the innovation of a technology from its slow early beginnings as it is developed, to an acceleration phase as it matures and, finally, to its stabilisation over time.

The electrification of vehicles is just one example of this. We believe we are standing at the beginning of a decade of transformational change that will induce multiple S-curves across many different industries.

At the heart of this change is electrification. Picture a light-emitting diode (LED) bulb, which emits light through a process called electroluminescence. In contrast to the traditional incandescent bulb, which emits light through the heating of a small metal filament, LEDs pass electrical currents through semiconducting material in order to emit photons.

This same photon emitting process can be used to transmit data. LiFi, similar to WiFi, is a wireless communication technology which utilises the LED process to transmit data from one object to another.
 

“At the heart of this change is electrification. … As electrification continues to develop, everything will become ‘smart’ and connected, blurring the lines between sectors and industries.”

 
While the details of LiFi might be fascinating, the key takeaway is that the electrification and digitalisation are intrinsically linked. As electrification continues to develop, everything will become ‘smart’ and connected, blurring the lines between sectors and industries.

Over the next decade, we anticipate the inception of multiple S-curves as technology improves and connectivity progresses. Traditional analogue products will make way for the new era of cloud computing and the Industrial Internet of Things. This shift has already started happening in smart cars, smart watches and even smart fridges. We consider this to be the Fourth Industrial Revolution (see Figure 2).
 

 
The Fourth Industrial Revolution is enabling us to move from a ‘fossil analog’ economy towards a ‘renewable electric digital’ economy.  It is at the heart of decarbonisation and the transition to a low carbon economy.  We refer to the trio of digitalisation, electrification and decarbonisation (DED) as the ‘DED nexus’. These dynamics are impacting every sector and every corner of the global economy.

We highlight the importance of considering the implications of these changes on portfolios. The DED nexus has been accelerated by the events of last year and we believe that, combined, they are powerful agents of positive change with regards to both societal and environmental sustainability goals.
