The Linkage Between Income Distribution and Clean Energy Investments: Addressing Financing Cost

Working paper
Ameli N., D.M. Kammen
FEEM Working Papers vol 10 (2012)


With a focus on alternative methods for accelerating clean energy policy adoption, this study introduces an innovative financing scheme for renewable and energy efficiency deployment. Financing barriers represent a notable obstacle for energy improvements and this is particularly the case for low-income households. Limited access to credit, due to socio-economic status and the lack of guarantees, are key issues related to financing barriers. Implementing a policy such as PACE – Property Assessed Clean Energy – allows for the provision of up-front funds for residential property owners to install electric and thermal solar systems and make energy-efficiency improvements to their buildings. This paper will inform the design of better policies tailored to the creation of the appropriate conditions for such investments to occur, especially when the lack of access to capital tends to stall them.

Going Electric: Expert Survey on the Future of Battery Technologies for Electric Vehicles

Working paper

FEEM Working Papers vol 93 (2012)


The paper describes the results of a survey, carried out with leading EU experts, on the capacity of both fully electric and plug-in hybrid vehicles to reach commercial success in the next twenty years. The success of electric transport is hampered by a combination of low range, scarce efficiency and high costs of batteries. Costs are expected to decrease in response to increasing sales volume and technical improvements, and advances would result from adequate investments in research, development and demonstration (RD&D). Experts’ judgements are collected to shed light on the inherently uncertain relationship between RD&D efforts and consequent technical progress, and to assess the complex dynamics that will hinder or support the widespread diffusion of electric vehicles. The analysis of the experts’ data results in a number of important policy recommendations to guide future RD&D choices and target commitments both for the EU and its member states.
