The purpose of this study is to determine past and future energy efficiency of fossil power generation in EU-27. It is found that the average efficiency for gas-fired power generation increased sharply from 34% in 1990 to 50% in 2005 and is expected to increase to 54% by 2015 (based on lower...

Barriers exist for improvement of energy efficiency, of which the principal-agent problem is considered an important one. The principal-agent problem is a potential barrier for energy policies based on economic instruments, as the decision maker may be partially insulated from the price signal...

The diffusion of cost-effective energy-efficiency measures (EEMs) in firms is often surprisingly slow. This phenomenon is usually attributed to a variety of barriers which have been the focus of numerous studies over the last two decades. However, many studies treat EEMs homogenously and assume...

This paper compares five methods to calculate CO2 intensity (g/kWh) of power generation, based on different ways to take into account combined heat and power generation. It was found that the method chosen can have a large impact on the CO2 intensity for countries with relatively large amounts...

We show that renewable energy contributes to Europe's 2020 primary energy savings target. This contribution, which is to a large extent still unknown and not recognized by policy makers, results from the way renewable energy is dealt with in Europe's energy statistics. We discuss the policy...
