Digitalization: A blessing for the power transformation – Uplaza

Many individuals now work partly or completely from dwelling. This protects petrol as a result of they now not must drive to the workplace—which is sweet for the power transition. Or not. As a result of at dwelling, they devour much more power for heating and cooking, and video calls additionally devour further power within the knowledge facilities of Microsoft, Zoom and the like. Does digitalization now save power or are we simply blowing extra CO₂ into the environment?

Evangelos Panos’ reply offers us hope. Along with former Paul Scherrer Institute (PSI) doctoral pupil Lidia Stermieri and researchers of ETH Zurich, the researcher from the Power Economics Group within the Lab for Power Methods Evaluation at PSI has proven in an elaborate calculation mannequin that “digital lifestyles” will really save 10% to twenty% in power in 2050 in comparison with 2020.

Rebound results—financial savings in a single place that result in extra consumption elsewhere—are greater than compensated for by extra environment friendly applied sciences and modifications in conduct. “Digitalization does not solve all problems,” says Panos, “but it supports the transformation of the energy system on the way to net zero emissions.” The researchers report on their findings within the journal Power Coverage.

Socio-economic choices taken under consideration

For her calculations, Stemieri used STEM (Swiss TIMES Power Methods Mannequin), which has been developed over years of painstaking work at Power Economics Group into a strong mannequin for simulating an power system. Six million equations with six million variables signify the Swiss power system and the interactions of applied sciences, power and emissions carriers, and sectors.

The variables are linked to one another in lots of dimensions, additionally throughout time and area, by way of the equations. This permits varied eventualities to be calculated as much as 2050, i.e., as much as the 12 months by which Switzerland goals to be carbon-neutral, and even past.

“It is the only model that can model development paths for Switzerland’s entire energy system over long periods of time and with a very good temporal resolution and a very detailed representation of all energy system sectors,” says Panos.

Nonetheless, STEM solely fashions the techno-economic facet of the power system and doesn’t present any data on socio-economic components. For instance, how individuals make choices about their power consumption. Individuals who solely earn a living from home could now not purchase a brand new automobile. Although they may purchase a warmth pump at dwelling, however provided that they’re the proprietor of the property and never a tenant. Many interwoven issues play a job right here, which collectively can have a big affect on the power system in the long run.

For this reason Stermieri has docked one other mannequin onto STEM: SEED (Socio-Financial Power mannequin for Digitalization). SEED maps the heterogeneity of the decision-making processes of actors in households, elements of the service sectors and trade as a way to analyze synergies and interactions within the introduction of energy-saving digital providers and practices.

These socio-economic choices are exchanged by way of an interface with STEM. Together, this has resulted in one of the crucial superior fashions for power methods with a nationwide scope in Europe.

Totally different assumptions and their eventualities

Stermieri used her mannequin to calculate and analyze two doable eventualities. Within the “Frozen” state of affairs, she assumes that society reveals little interest in advancing digitalization and that it subsequently stagnates. In distinction, digitalization accelerates within the “Accelerated” state of affairs. Society reveals a constructive perspective in direction of digitalization and technological growth, supporting new digital social practices, progresses accordingly. This additionally reveals the constructive affect on power consumption.

Stermieri wanted to run her mannequin 20 to 30 occasions for every state of affairs, which takes a quick PC round 60–90 hours of intense computations. Throughout every of those runs, the 2 power methods interacted with one another a number of occasions in order that the interaction between society and expertise could possibly be realistically modeled. “We’re not predicting the future,” emphasizes Stermieri, “we’re exploring it by calculating scenarios based on the what-if principle.”

Even when none of those eventualities will materialize in precisely the identical means, they’re very priceless as a decision-making support for these accountable in politics and enterprise. “The scenarios show possible courses of action and their consequences. This is particularly interesting when comparing different scenarios,” says Stermieri.

Future work to combine psychological results

Stermieri’s mannequin covers all sectors—households, trade and politics—and never simply particular person applied sciences. “This makes it unique in Europe,” says Panos. It additionally reveals the event from the straightforward fashions from the Nineteen Eighties, which initially solely calculated the power sector in a easy means, to fashions that additionally simulate the interplay of various applied sciences.

The present mannequin additionally consists of socio-economic elements and is subsequently extra interdisciplinary than ever earlier than. Nonetheless, even that is solely an intermediate step in direction of much more sensible fashions, which may also take into account findings from psychology sooner or later.

Panos is engaged on this with doctoral pupil Shadi Firoozyalizadeh in a sub-project of the CoSi analysis program (Co-Evolution and Coordinated Simulation of the Swiss Power System and Swiss Society). The mission goals to research the social change processes which can be needed for the transformation of the power system.

Within the mission, psychologists are investigating, amongst different issues, how individuals make choices about their power consumption and expertise decisions. Firoozyalizadeh will then combine this decision-making psychology into the SEED mannequin.

Panos is for certain that this technology of fashions will result in much more knowledgeable choices when designing a brand new power and local weather coverage. “Policymakers will have a unique tool to support them in their decisions that takes greater account of social aspects, because technology alone is not the solution.”
