How countries in the G20 develop better policies for managing the energy transition

Posted on 26 June 2019

The World Energy Council recognises the value of adopting a whole energy systems approach in delivering the benefits of sustainable energy to all.

Energy transition is a connected policy challenge. Success involves managing energy security, equity and environmental sustainability throughout the transition process. The Council’s Energy Trilemma Index, developed with the support of Oliver Wyman, provides an objective rating of national energy policy and performance across these three dimensions.

The 2018 World Energy Trilemma Index compared 125 countries around the world, using a broad set of key energy indicators. As G20 leaders meet in Osaka this week and in anticipation to the all-new Trilemma that will be revealed in September’s upcoming 24th World Energy Congress, we take a closer look at their national ‘Trilemma triangles’ and the associated policy choices and transition pathway performance.

Progress on pathways to sustainability

Managing multiple policy priorities is a challenging process that benefits from looking at synergies, as well as balancing trade-offs. A deep-dive into Trilemma scores across the G20 countries provides important insights about the role of energy policy in sustaining energy transition. With greater international recognition of continued climate change, the world’s leading economies are searching for pathways to deeper, affordable and socially just decarbonisation. Energy policy is an important lever for action in decoupling carbon-emissions from economic growth, and in meeting shifting and new demand for heat, fuel and power in other sectors. This is a high priority, as 39% of the G20’s CO2 can be attributed to electricity generation.

Tracking Trilemma performance over time shows that G20 countries follow two clear, but not mutually exclusive, routes to lowering emissions: decarbonisation of the electricity supply and reducing electricity demand.

  • European countries have made sustained efforts to decarbonise electricity production and manage demand, with the UK, Italy and France ahead with strong sustainability performance.
  • Power demand is growing rapidly in India, Indonesia and especially China. While their power mix is decarbonising, it is happening at a slower pace.The rapid evolution is stark: in 2004, electricity-derived CO2 emissions per inhabitant were twice as high in the UK than in China, whereas in 2016 they were twice higher in China than in the UK.
  • Australia, Saudi Arabia, the US, Korea and Russia have the most carbon intensive power systems in the G20, due to a high share of fossil fuels in their electricity mix coupled with high power consumption levels when compared to other G20 countries.

Diversity for growing security

Trilemma analysis reveals that the most secure energy systems do not necessarily require significant reserves or net exports. Top performing countries have developed a diverse energy mix and a number of strong global relationships for long term supply.

A clear pathway to increased security is to diversify sources of electricity generation. Multiple and diverse sources of electricity enable a stable power system that is resilient to shocks in fuel prices or weather impacts. Higher security performers in the G20 are those countries with high diversity of electricity generation.

  • Canada, the United States, Germany, Russia, the United Kingdom, and Italy have the highest Trilemma scores for diversity of power generation and these translate to the highest security scores.
  • Energy exporters like Saudi Arabia, South Africa, Australia and Indonesia, have the lowest Trilemma scores for diversity of power generation. While being net exporters is an asset for energy security, none of these countries have high security dimension scores.

 

Managing energy equity through green transitions

Transitioning to renewable and lower carbon electricity generation while keeping electricity prices at affordable levels is a key challenge for G20 countries.

  • Solar and wind power have significantly developed in the European Union to reach a 13% share of the electricity mix in 2016, up from 3% in 2006. This has led to a 27% decrease in CO2 emissions from power generation in the EU between 2006 and 2016. However, feed-in tariff policies to help establish new technologies have contributed to rising electricity prices and growing concerns about the affordability of power and heat for households and industry. Several European countries have seen their Energy Equity indicators impacted by these trends.
  • The increasing penetration of renewables in Japan, Australia and Brazil could place these countries on a comparable pathway although there is hope that the scalable cost efficiencies of solar and wind power will not impact equity.
  • China, India, and Mexico have significant potential to develop their solar and wind resources so that generation capacity from these sources could become cost competitive with thermal sources. Solar and wind generation has increased threefold in Mexico between 2012 and 2016 with electricity prices remaining stable over the period.

 

What enables agile and adaptable transition?

G20 countries have strong industrial- and growing service- based economies, and shared goals for sustainable growth. Although they take different pathways towards energy transition, reflecting differing national contexts, all aim to make policy choices which represent ‘lowest overall cost, best fit to societies’.

The Trilemma Index provides G20 governments with a tool they can use to monitor individual progress, share learning and benchmark best practices. It offers a unique and practical platform to address new and common energy policy imperatives. Questions of comparison can be explored:

  1. What does the comparison of leaders and laggards tell us about technological neutrality in leveraging existing technologies and innovation to achieve deeper and affordable decarbonisation?
  2. What new policy choices (synergies, co-benefits, trade-offs) emerge in integrated policy pathfinding?

The Trilemma Index tool can be used in combination with the Council’s World Energy Scenarios for forward assessment exploring new opportunities in managing energy transition for prosperity. Policymakers can use Trilemma Trajectories to explore emerging sector coupling opportunities e.g. linking energy transition management and new industrial development plans and new mobility policies.
