Melting-pots and salad bowls: the current debate on electricity market design for RES integration

This paper discusses a series of issues regarding the economic integration of intermittent renewables into European electricity markets. This debate has gained in importance following the large-scale deployment of wind farms and photovoltaic panels. As intermittent renewables constitute a significant share of the installed generation capacity, they cannot be kept isolated from the electricity markets. We argue that RES integration is first and foremost an issue of economic efficiency, and we review the main debates and frameworks that have emerged in the literature. we first consider to what extent intermittent resources should be treated the same way as dispatchable resources. we then analyse the different tools that have been proposed to ensure the required flexibility will be delivered: finer temporal granularity and new price boundaries, integration of a complex set of balancing markets, and introduction of tailor–made capacity remuneration mechanisms. Finally we introduce the topic of space redistribution, confronting crosscontinental markets integration to the emergence of a mosaic of local markets

Integrating Life Cycle Management for a more Circular Data Centre Industry

The Data Centre Industry (DCI) is concentrated in North-West Europe, especially UK, Germany, France & Netherlands. DC equipment is replaced every 1–5 years, substantially contributing to the production of WEEE (Waste Electrical & Electronic Equipment), one of the fastest growing waste streams. WEEE from DC equipment contains Critical Raw Materials of high technical and economic importance and vulnerable to supply disruption, partly exported or sent to landfill at end of life. At present small share of DC equipment Critical Raw Materials are recycled and recovered per year. In this context, project partners from UK (London South Bank University), France (TEAM2, Terra Nova Development and WeLOOP), Germany (Wuppertal Institute for climate, environment and energy) and Netherlands (Green IT Amsterdam) are working together on a Circular Economy for the Data Centre Industry (CEDaCI). CEDaCI will facilitate the implementation of a Circular Economy (CE) for Critical Raw Materials in NWE and reduce the environmental impact arising from the growth in redundant equipment, by simultaneously increasing CRM recovery, reducing use of virgin materials and developing a secure and economically viable CRM supply chain. The project if co-funded by Interreg North-West Europe Programme. This contribution aims at presenting the CEDaCI project and sharing results of the LCM situational analysis for Data Centre Industry. The results of this phase include: State of art and assessment of current practices & emerging trends (with focus in all partner countries), Identify challenges and barriers and potential solutions for implementation, Establishment of criteria (age of the equipment, technology, components, etc.) for selection of equipment for refurbishing and recycling

Induced innovation in energy technologies and systems: a review of evidence and potential implications for CO2 mitigation

We conduct a systematic, interdisciplinary review of empirical literature assessing evidence on induced innovation in energy and related technologies. We explore links between demand-drivers (both market-wide and targeted); indicators of innovation (principally, patents); and outcomes (cost reduction, efficiency, and multi-sector/macro consequences). We build on existing reviews in different fields and assess over 200 papers containing original data analysis. Papers linking drivers to patents, and indicators of cumulative capacity to cost reductions (experience curves), dominate the literature. The former does not directly link patents to outcomes; the latter does not directly test for the causal impact of on cost reductions). Diverse other literatures provide additional evidence concerning the links between deployment, innovation activities, and outcomes. We derive three main conclusions. (1) Demand-pull forces enhance patenting; econometric studies find positive impacts in industry, electricity and transport sectors in all but a few specific cases. This applies to all drivers - general energy prices, carbon prices, and targeted interventions that build markets. (2) Technology costs decline with cumulative investment for almost every technology studied across all time periods, when controlled for other factors. Numerous lines of evidence point to dominant causality from at-scale deployment (prior to self-sustaining diffusion) to cost reduction in this relationship. (3) Overall Innovation is cumulative, multi-faceted, and self-reinforcing in its direction (path-dependent). We conclude with brief observations on implications for modeling and policy. In interpreting these results, we suggest distinguishing the economics of active deployment, from more passive diffusion processes, and draw the following implications. There is a role for policy diversity and experimentation, with evaluation of potential gains from innovation in the broadest sense. Consequently, endogenising innovation in large-scale models is important for deriving policy-relevant conclusions. Finally, seeking to relate quantitative economic evaluation to the qualitative socio-technical transitions literatures could be a fruitful area for future research

Green Tax Reform, Endogenous Innovation and the Growth Dividend

We study theoretically and numerically the effects of an environmental tax reform using endogenous growth theory. In the theoretical part, mobile labor between manufacturing and R&D activities, and elasticity of substitution between labor and energy in manufacturing lower than unity allow for a growth dividend, even if we consider preexisting tax distortions. The scope for innovation is reduced when we consider direct financial investment in the lab, or elastic labor supply. We then apply the core theoretical model to a real growing economy and find that a boost in economic growth following such a carbon policy is a possible outcome. Lump-sum redistribution performs best in terms of effciency measured by aggregate welfare, while in terms of equity among social segments its progressive character fails when we consider very high emissions reduction targets

Technology Transfer in the Non-Traded Sector as a Means to Combat Global Warming

The paper considers a situation where two countries - the North and the South - use a non-traded polluting input to produce the goods for final consumption. The North is more efficient in both, production and abatement processes. The study compares the effects of the transfer of abatement technology by the North to the South under autarky with the free trade situation, assuming that the North pre-commits to an international protocol to keep the global pollution under a fixed level. The conditions under which either full or partial technology is transferred in autarky are determined. It is shown that under free trade no such transfer is possible. With trade even though the North wants a complete transfer of technology, the South refuses it

Optimal Afforestation Contracts with Asymmetric Information on Private Environmental Benefits

We investigate the problem of subsidising afforestation when private information exists with respect to the level of private utility derived from the project. We develop a simple model that allows for an intelligent design of contracts when information is asymmetric. The model involves the Principal and two groups of agents (landowners): a green' group deriving high private utility from the projects and a conventional' group deriving lower utility. Afforestation projects may be produced in different environmental quality, and we distinguish between two cases, a high quality and a low quality project. We find that the optimal set of contracts under asymmetric information involves two different contracts. One in which green landowners are somewhat overcompensated for projects of high quality, and one where conventional landowners are offered contracts including lower quality projects, compared to the symmetric case, but with compensation equal to his indifference payment. It is the ability to reduce quality requirements along with subsidies offered that allows for revelation of the private information. Finally, we discus how the results obtained may be used in the implementation of incentive schemes
