There is an urgent timeframe in which we need to accelerate our response to the challenges of climate change. The rapid diffusion of low-carbon innovations has been identified as a key strategy for maintaining average global temperature rise at or below 1.5°C. Low-carbon innovations are novel products or services that result in lower carbon emissions compared to established technologies. Diffusion is the process through which these innovations are communicated through societal channels over time, gaining increasing market share through widespread adoption and continued use. However, there are gaps in our understanding about how to measure and predict the rate and mechanisms through which multiple innovations can be diffused, and how they might mitigate climate change in an accelerated timeframe. To better understand how innovations being offered to energy users contribute to a low-carbon energy system transformation, our research project— led by Dr. Christina Hoicka and carried out through the social exergy + energy lab at York University— developed a novel framework to measure the potential for existing low-carbon innovations to disrupt and decarbonize energy systems. This framework is described in more detail in our recently released working paper.

Historically, energy transitions have been a gradual process that take place over the span of many decades. This is because energy systems are made up of complex networks of carbon-intensive technologies, infrastructure, institutions, and behavioral norms that, over time, are locked-in through path-dependent processes. The result is an interlocking system of technologies and actors that constrain the emergence of low-carbon innovation. Disruptive innovations are products or services that incorporate new features or attributes that can disrupt existing technologies and markets, leading to broad technological, social and political changes. Incremental innovations offer improvements to products or services, such as improved costs for consumers, but do not lead to broad technological or societal change. Low-carbon innovations tend to be incremental and reinforce the current energy system. Innovations with an environmental focus often experience slow rates of diffusion, and usually only one third successfully diffuse into mainstream consumer markets (defined as being above 15% market share). Furthermore, there is a tendency for studies to simplify the complexity of the diffusion process by focusing on a single technology case study, or on a small scope of influencing factors. However, energy technologies are rarely adopted and used in isolation. Our research addresses these gaps by:

  • Examining the diffusion of multiple innovations;
  • Developing a framework that conceptualizes four key variables: (1) innovation dissemination rates; (2) the potential for the innovations to contribute to energy system transformation; (3) the mechanisms of innovation adoption; and (4) the potential for the innovations to address energy justice;
  • Categorizing innovations by their disruptive characteristics, such as how much they contribute to decarbonization, decentralization and democratization; and,
  • Analysing multiple influencing factors to support innovation scale-up, including policy support through economic, regulatory, and knowledge creation and diffusion instruments, and legitimacy support through discourse framing and through actors and networks.

Between 2017 and 2019, we identified 131 low-carbon innovations that had been offered to energy users in Ontario between 1998 and 2018. Some examples of innovations include: a municipal energy planning program, electric vehicle charging policy incentives, a community energy storage project, energy audits and regional sustainability initiatives. We identified them using desk research, a survey of experts across energy, environment, innovation and social innovation sectors, and a survey of the providers of the innovations themselves. Notably, our research found that:

  • The majority of the innovations being offered to energy users in Ontario have incremental characteristics. Innovations with disruptive decarbonization characteristics are associated with lower rates of diffusion compared to innovations with incremental decarbonization characteristics.
  • One quarter of the innovations achieved diffusion rates above 15% market share, and many experienced diffusion rates of less than 1%.
  • Many of the innovations lack the necessary technology-specific regulatory, economic, and knowledge creation and diffusion policy supports to achieve scale-up and diffusion in mainstream markets.
  • Innovations with strong policy support through economic instruments are associated with higher rates of diffusion compared to innovations with less support through economic policy instruments.

The methodology, analytical framework and lessons learned can be replicated and applied as empirical analysis by policymakers and practitioners to a variety of contexts to inform the allocation – or reallocation – of resources towards innovations that have the potential to create transformation in the energy system and accelerate system-wide decarbonization. For example, it can be used to evaluate:

  • Whether, across a mix of innovations in a particular energy system, system reinforcing innovations are receiving more supports than disruptive innovations. For example, providing more support to scale-up efficient natural gas furnaces than to deep retrofits of building envelopes coupled with heat pumps.
  • Whether the right mix of low-carbon innovations have optimal supports to diffuse into markets. For example, whether complementary innovations, such as solar and wind power, or electric vehicles and demand response, are receiving similar supports for scale-up to achieve optimal outcomes.
  • The types of supports for scale-up being offered compared to the range of options.

This research can help experts map the current landscape of low-carbon innovations being offered to energy users in their jurisdictions, to inform an accelerated pathway towards system-wide decarbonization.
