This paper studies technological change in renewable energies, providing empirical evidence on the determinants of innovative activity with a special emphasis on the role of knowledge spillovers. We investigate two major renewable energy technologies wind and solar across a panel of 21 OECD...

This paper compares multi-criteria decision aiding (MCDA) and data envelopment analysis (DEA) approaches for assessing renewable energy plants, in order to determine their performance in terms of economic, environmental, and social criteria and indicators. The case is for a dataset of 41...

Los biocombustibles han experimentado una fuerte expansión gracias a los incentivos otorgados por los poderes públicos y a algunas ventajas como la capacidad para reducir la dependencia energética exterior, la mayor creación de empleos, especialmente en zonas rurales, o el menor impacto...

According to the WBCSD definition, eco-efficiency is achieved through the delivery of "competitively priced goods and services that satisfy human needs and bring quality of life while progressively reducing environmental impacts of goods and resource intensity throughout the entire life-cycle to...

In the course of current climate negotiations, the world is watching the United States in particular. Together with China, the U.S. is by far the largest emitter of greenhouse gases. Real progress in protecting the global climate requires substantial action on America's part. The U.S. has the...

This article presents current investment and operating costs of ethanol and biodiesel plants for alternative prices of feedstock. The price of these two fuels is estimated for alternative prices of crude oil with the existing renewable fuels policy. The excise tax credit, currently $0.51 per...

Wind and solar energy are often expected to fall victim to their own success: the higher their share in electricity production, the more their revenue on electricity markets (their “market value”) declines. While in conventional power systems, the market value may converge to zero, this...

Various energy investments are possible in residential buildings. Owners' opportunities are moreover extending with smart technologies and optimisation options, as well as with the rise of collective investment projects. In this context, we investigate owners' investment decisions by conducting...

Complexity within the decision-making process can inhibit energy investment for residential buildings. In this paper, we explore effects of complexity on investment behaviour, as well as the impact of experience with similar investments and of subsidies as a promoting policy tool. To shed light...

The split incentive problem leads to under-investment in energy improvements of rental buildings. This prevents the large CO2 savings potential from being achieved and leads to disadvantages for tenants. New investment opportunities and a willingness of tenants to pay for investments made by the...
