Exploring the role of servitization to overcome barriers for innovative energy efficiency technologies – the case of public LED street lighting in German municipalities

In this paper we analyse the case for public application of LED street lighting. Drawing from the energy services literature and transaction cost economics, we compare modes of lighting governance for modernisation. We argue that servitization can accelerate the commercialisation and diffusion of end-use energy demand reduction (EUED) technologies in the public sector if third party energy service companies (ESCo) overcome technological, institutional and economic barriers that accompany the introduction of such technologies resulting in transaction costs. This can only succeed with a supportive policy framework and an environment conducive towards the dissemination of specific technological and commercial knowledge required for the diffusion process

Crowdfunding and social capital: a systematic review using a dynamic perspective

Several literature reviews on crowdfunding categorise crowdfunding research into different perspectives but provide limited theory development. The social capital literature offers a promising lens for understanding crowdfunding. We provide a comprehensive review of how internal social capital develops through crowdfunding activities and how both external and internal social capital affect crowdfunding campaign dynamics, including early-stage performance, general process, funding performance and post-campaign performance. Most researchers report a positive but dynamic impact of social capital on crowdfunding activities over time. We apply a dynamic view to develop a conceptual model that explains how external and internal social capital affect crowdfunding campaigns. We conclude with proposed directions for future research, including an analysis of the negative aspects and the causal effects of social capital

Modes of governance for municipal energy efficiency services – The case of LED street lighting in Germany

AbstractEnergy efficiency retrofits are often impeded by high perceived investment risks, long payback periods and a lack of skills. At the municipal level these issues are particularly pronounced as procuring, implementing, and managing retrofits can exceed existing municipal governance capacities. The diffusion of municipal LED street lighting as a replacement for conventional lighting serves as an example. This paper argues that technological (e.g. complexity and maturity), economic (e.g. selling services vs. products and financing costs), institutional (e.g. property situation and contracts) and competency barriers to retrofitting (e.g. lack of measurement capacity and qualified facilitators) translate into transaction costs. We develop a taxonomy of appropriate modes of municipal retrofitting governance based on transaction costs economics. The findings indicate that more market-based solutions, energy performance contracts in particular, can facilitate the procurement of innovative energy efficiency retrofitting solutions and associated investments among municipalities if neutral tenders, open-book accounting, municipal ownership and intermediary organisations allow municipalities to choose appropriate governance structures for particular technologies and retrofits

Drivers and barriers for municipal retrofitting activities – Evidence from a large-scale survey of German local authorities

Local authorities are key actors for implementing innovative energy efficiency technologies (retrofitting) to reduce end-use energy demand and consequently reduce negative effects of high energy use such as climate change and public budget deficits. This paper reports the results of a large-scale survey of German municipalities by assessing drivers and barriers for deploying LED street lighting as an example of innovative retrofits. The results indicate that competencies and capacities, transparency of the underlying technology base, and a clear proposition of savings are crucial drivers for municipal retrofitting engagement. Most significant barriers include lack of experience, the tendency to wait for future improvements of innovative energy efficiency technologies, and existing contracts with energy suppliers, manufacturers, or other conventional retrofitting contractors. Investments in municipal competency building (both regarding technologies and procurement) as well as diffusing standard tendering criteria and (public) monitoring of their effectiveness are highly recommended to accelerate the municipal modernization process

Can the EU taxonomy for sustainable activities help upscale investments into urban nature-based solutions?

We analyze the potential of the European Union (EU) Taxonomy (ET) for Sustainable Activities to mobilize investments for the sustainability transition toward urban nature-based solutions (UNBS). We map the current investment landscape of UNBS in Europe and combine this mapping with document analysis of UNBS inclusion in the ET to understand how the ET might help overcome the well-documented barriers to UNBS finance. We suggest that the ET has a legitimizing effect on UNBS as climate investments, which can support their uptake, but also conclude that only some UNBS subtypes are explicitly included when they fit with existing investment classes. In particular, the ET (1) disregards innovative - and specifically urban - UNBS types and (2) fails to provide incentives for investments that can deliver multiple sustainable objectives, which would enhance the investment case for UNBS. Since the current investment landscape of UNBS is characterized by a strong presence of public actors and a high incidence of co-financing, we recommend that public actors leverage the ET to obtain private funding for UNBS via (green) bond issuance and public-private co-finance instruments. Our analysis indicates that the ability of the ET to upscale investments for specific sustainability transitions depends on the interplay among their current investment landscapes, specific financing barriers, and explicit inclusion in the ET

The wisdom of the crowd in funding

Crowdfunding has enabled large crowds to fund innovative projects. This type of funding might tap into the wisdom of crowds who were previously disconnected from the funding process. We distinguish between in-crowd and out-crowd funders (with and without ties to project creators) in order to test for heterogeneity in their information use. Based on the analysis of a large-scale survey amongst project funders, this paper shows that in-crowd investors rely more on information about the project creator than out-crowd investors. Out-crowd investors do not seem to attach more importance to information about the project itself than in-crowd investors, except in the case of donation-based crowdfunding. For financial return crowdfunding, financial information becomes less important once a strong relationship with the project creator is established. Our study allows project creators to target information to specific audiences based on their relationship strength across different types of crowdfunding projects

Representation of financial markets in macro-economic transition models-a review and suggestions for extensions

As the energy transition accelerates and renewable energy technologies become cost-competitive with fossil fuels in many countries, the availability of finance could become a bottleneck. Integrated assessment models (IAMs) and other macro-economic transition (MET) models typically do not feature detailed financial markets and do not sufficiently consider financing barriers and opportunities for the transition to carbon neutrality. While progress has been made in the representation of financial markets in macro-models since the financial crisis of 2008 the focus has been on financial (in)stability of the financial sector, not its ability to finance investment projects in the energy transition. Hence, a crucial gap remains, preventing macro model-based analysis of financing barriers and policy interventions that may accelerate the energy transition. In this article we review how state-of-the-art macro-economic models consider the financial sector. From this review we identify what elements are still missing to adequately model the financial dynamics and challenges for the energy transition specifically. Based on a discussion of relevant parts of the finance literature, we then propose four steps to improve the representation of finance in global IAMs and MET models more generally
