Fuel poverty can be defined as “the inability to afford adequate warmth in the home" and it is the result of the combination of three items: low household income, housing lack of energy efficiency and high energy bills. Although it affects a growing number of households within the European Union only some countries have an official definition for it. In 2013, the European Parliament claimed the Commission and Estate Members to develop different policies in order to fight household energy vulnerability. The importance of tackling fuel poverty is based on the critical consequences it has for human health living below certain temperatures. In Spain some advances have been made in this field but main existing studies remain at the statistical level and do not deepen the understanding of the problem from the perspective of dwelling indoor habitability conditions. What is more, this concept is yet to be officially defined. This paper presents the evaluation of fuel poverty in a building block of social housing located in the centre of Zaragoza and how this issue determined the strategies implemented in the energy retrofitting intervention project. At a first step, fuel poverty was appraised through the exploration of indoor thermal conditions. The adaptive thermal comfort (UNE-EN 15251:2008) method was used to establish the appropriate indoor temperatures and consequently to determine what can be called 'comfort gap'. Results were collated and verified with energy bills collection and a survey work that gathered data from neighbours. All this permitted pointing out those households more in need. Results from the social analysis combined with the evaluation of the building thermal performance determined the intervention. The renovation project was aimed at the implementation of passive strategies that improve households thermal comfort in order to alleviate households fuel poverty situation. This research is part of the project NewSolutions4OldHousing (LIFE10 ENV/ES/439) cofounded by the European Commission under the LIFE+ Programme.

Fuel poverty can be defined as ‘the inability to afford adequate warmth in the home’ and it is the result of the combination of three factors: low household income, lack of energy efficiency and high energy bills. Within this context, the present research is aimed at characterizing, for the first time, the housing stock of fuel-poor households in the Autonomous Region of Madrid. Fuel poverty incidence was established and households were divided into six different groups according to their relative position regarding fuel and monetary poverty. The housing stock of each group is characterized and those households most in need are identified. These results enable energy retrofitting priorities to be established, focusing on the needs of the different household groups and accounting for their housing stock characteristics. This allows Spanish energy retrofitting policies to be assessed for their capability of tackling fuel poverty and makes it possible to suggest some improvements.

As advanced Cloud services are becoming mainstream, the contribution of data centers in the overall power consumption of modern cities is growing dramatically. The average consumption of a single data center is equivalent to the energy consumption of 25.000 households. Modeling the power consumption for these infrastructures is crucial to anticipate the effects of aggressive optimization policies, but accurate and fast power modeling is a complex challenge for high-end servers not yet satisfied by analytical approaches. This work proposes an automatic method, based on Multi-Objective Particle Swarm Optimization, for the identification of power models of enterprise servers in Cloud data centers. Our approach, as opposed to previous procedures, does not only consider the workload consolidation for deriving the power model, but also incorporates other non traditional factors like the static power consumption and its dependence with temperature. Our experimental results shows that we reach slightly better models than classical approaches, but simul- taneously simplifying the power model structure and thus the numbers of sensors needed, which is very promising for a short-term energy prediction. This work, validated with real Cloud applications, broadens the possibilities to derive efficient energy saving techniques for Cloud facilities.

The computational and cooling power demands of enterprise servers are increasing at an unsustainable rate. Understanding the relationship between computational power, temperature, leakage, and cooling power is crucial to enable energy-efficient operation at the server and data center levels. This paper develops empirical models to estimate the contributions of static and dynamic power consumption in enterprise servers for a wide range of workloads, and analyzes the interactions between temperature, leakage, and cooling power for various workload allocation policies. We propose a cooling management policy that minimizes the server energy consumption by setting the optimum fan speed during runtime. Our experimental results on a presently shipping enterprise server demonstrate that including leakage awareness in workload and cooling management provides additional energy savings without any impact on performance.

The energy demand for operating Information and Communication Technology (ICT) systems has been growing, implying in high operational costs and consequent increase of carbon emissions. Both in datacenters and telecom infrastructures, the networks represent a significant amount of energy spending. Given that, there is an increased demand for energy eficiency solutions, and several capabilities to save energy have been proposed. However, it is very dificult to orchestrate such energy eficiency capabilities, i.e., coordinate or combine them in the same network, ensuring a conflict-free operation and choosing the best one for a given scenario, ensuring that a capability not suited to the current bandwidth utilization will not be applied and lead to congestion or packet loss. Also, there is no way in the literature to do this taking business directives into account. In this regard, a method able to orchestrate diferent energy eficiency capabilities is proposed considering the possible combinations and conflicts among them, as well as the best option for a given bandwidth utilization and network characteristics. In the proposed method, the business policies specified in a high-level interface are refined down to the network level in order to bring highlevel directives into the operation, and a Utility Function is used to combine energy eficiency and performance requirements. A Decision Tree able to determine what to do in each scenario is deployed in a Software Defined Network environment. The proposed method was validated with diferent experiments, testing the Utility Function, checking the extra savings when combining several capabilities, the decision tree interpolation and dynamicity aspects. The orchestration proved to be valid to solve the problem of finding the best combination for a given scenario, achieving additional savings due to the combination, besides ensuring a conflict-free operation.

Climate change is critically impacting the environment and economy at the local level. County governments have an opportunity to adopt climate change policies that address local environmental and economic concerns. The Colorado counties of Boulder, Gunnison, and Pitkin have all adopted some form of climate change policies. There are some components of each of these policies that are more effective in terms of economic, environmental, and community benefits. An effective climate change policy clearly states specific cost analyses, environmental impacts at the local level, the relationship between impacts and the community, and the economic benefits of policy adoption. This Capstone project addresses specific cost and energy analyses and provides a beneficial policy framework for county governments.

This paper defines a sustainable energy plan to provide the basis for renewable energy initiatives that will increase energy security, reduce negative economic impacts and provide a cleaner environment. The hotel, agriculture, transportation, construction, utility, government and private sectors will play pivotal roles in achieving targets and will see significant gains. Government policies, educational campaigns and financial incentives will be required to facilitate and encourage renewable energy development and entrepreneurship. Utilization of solar energy, energy conservation measures and the use of efficient and alternative fuel vehicles by the commercial/industrial and private sectors will be crucial in meeting targets. The utility company will be charged with developing large scale renewable energy applications and with improving efficiency of the electrical system.

THE ISSUE European Union energy policy is guided by three objectives: sustainability, security of supply and competitiveness. To meet its goals in these areas, the EU is updating its energy strategy with new targets for 2030. The starting point for this is the assessment of the previous EU climate and energy package, at the centre of which were the 20-20-20 targets for 2020. Although the EU is largely on track to meet these targets, EU energy policy is generally not perceived as a success. Recent events have undermined some of the assumptions on which the 2020 package was built, and the policies for achieving the 2020 targets – although at first sight effective – are far from efficient.

In the current volatile climate, the EU needs a strategy towards Russia that goes beyond sanctions. In reviewing the European Neighbourhood Policy and the Eastern Partnership, the EU’s incoming leadership should be more sensitive towards the existing political, diplomatic, economic, energy and military ties between Russia and the countries in the common neighbourhood. After all, it is by exploiting these ties that Russia was able to turn this neighbourhood into an area of destructive competition − the primary victim of which is Ukraine. Understanding Russia’s perceptions and being sensitive to these longstanding ties does not mean justifying their use by the Kremlin. Nevertheless, factoring these ties into the EU’s policies vis-à-vis its Eastern neighbourhood is a prerequisite for more reflective, responsive and effective EU policies.

For many years the European Union has been improving the efficient use of energy resources and yet the demand for energy in the EU continues to increase. When Europe belonged to one of the world’s key energy markets with relatively easy access to energy resources, growing energy needs were not seen as a source of concern. Today, however, as the competition for energy resources is intensifying and the global position of the EU energy market is being challenged by growing economies in the developing countries, above all China and India, the EU needs to adopt bold policies to guarantee the sustainable supply of energy. This report argues the EU needs to develop a fully-fledged external energy policy; i.e. a common, coherent, strategic approach that build bridges between the interests and needs of the EU integrated energy market on the one hand and supplier countries on the other. The EU’s external energy policy has two main objectives. The first one is to ensure a sustainable, stable and cost-effective energy supply. The second is to promote energy market integration and regulatory convergence with neighbouring countries (often but not always this supports the achievement of the first objective). However, in order to improve its effectiveness, the EU’s external energy policy needs to be seen in a broader economic and political context. Any progress in energy cooperation with third countries is contingent upon the EU’s general stance and offer to those countries.

1. The priority of Ankara's energy policy is to make Turkey an important transit corridor for energy resources transported to the EU. Turkey wishes to play an active role in the distribution and sale of gas and oil flowing across its territory. 2. Transit and sale of energy resources, and gas in particular, are expected to provide a major source of income for Turkey and a tool by which Ankara will be able to build its position in the region and in Europe. 3. Since Turkey is an EU candidate country, Brussels will probably welcome Turkey's role as a transit corridor as much as Ankara will. 4. The success of Ankara's energy strategy hinges on developments in Turkey's internal energy market. 5. It also depends on a number of external factors including: - Export policies and internal situation in producer countries. Most importantly, it depends on: a. Russia and its energy policy priorities b. Stability in the Middle East. - Policies of consumer countries, including the EU in particular. - Policies of world powers present in the region (USA).

This paper analyses the consequences of enhanced biofuel production in regions and countries of the world that have announced plans to implement or expand on biofuel policies. The analysis considers biofuel policies implemented as binding blending targets for transportation fuels. The chosen quantitative modelling approach is two-fold: it combines the analysis of biofuel policies in a multi-sectoral economic model (MAGNET) with systematic variation of the functioning of capital and labour markets. This paper adds to existing research by considering biofuel policies in the EU, the US and various other countries with considerable agricultural production and trade, such as Brazil, India and China. Moreover, the application multi-sectoral modelling system with different assumptions on the mobility of factor markets allows for the observation of changes in economic indicators under different conditions of how factor markets work. Systematic variation of factor mobility indicates that the ‘burden’ of global biofuel policies is not equally distributed across different factors within agricultural production. Agricultural land, as the pre-dominant and sector-specific factor, is, regardless of different degrees of inter-sectoral or intra-sectoral factor mobility, the most important factor limiting the expansion of agricultural production. More capital and higher employment in agriculture will ease the pressure on additional land use – but only partly. To expand agricultural production at global scale requires both land and mobile factors adapted to increase total factor productivity in agriculture in the most efficient way.

This report aims to identify, explain and detail the links and interactions in southern and eastern Mediterranean countries (SEMCs) between energy supply and demand and socio-economic development, as well as the potential role of energy supply and demand policies on both. Another related aim is to identify and analyse, in a quantitative and qualitative way, the changing role of energy (both demand and supply) in southern Mediterranean economies, focusing on its positive and negative impact on socio-economic development. This report investigates in particular: o The most important channels through which resource wealth can contribute to or hamper economic and social development in the analysed region; o Mechanisms and channels of relations between energy supply and demand policies and economic and social development. The burdens of energy subsidies and ‘oil syndrome’ are of particular relevance for the region. An integrated socio-economic development and energy policy scenario approach showing the potential benefits and synergies within countries and the region is developed in the final part of the report.

This paper has two objectives. First, it attempts to establish the potential of policies on energy efficiency and energy demand-side management in the southern Mediterranean region. Second, by examining past trends in energy intensity and trends up to 2030, it analyses the prospects and costs of such policies, compared with expected developments in the price of energy resources. Based on both analyses (MEDPRO WP4) and on prospects for growth (MEDPRO WP8), it seems that energy intensity in the Mediterranean should fall perceptibly by approximately 13% in the next 20 years. But given the programmed energy mix, this will not limit emissions of CO2, which are likely to increase by more than 90%. The paper first presents the rationale for demand-side management (DSM) policies. After a general discussion of concepts, it tackles the question of instruments and measures for implementing such policies, before posing the question of the cost-efficiency approach for monitoring the measures the authorities introduce. Secondly, the paper assesses energy consumption and energy efficiency in the countries of the southern Mediterranean and the ways in which their main economic sectors have changed in recent decades. The third section outlines the demand management measures introduced and, taking Tunisia and Egypt as examples, estimates the cost of such policies. The fourth and last section offers a forecast analysis of energy consumption in the Mediterranean up to 2030, highlighting probable trends in terms of final consumption, energy intensity, energy mix and emissions of CO2. The section concludes with estimates in terms of cost, comparing objectives for lower intensity, results in terms of resource savings and the types of costs this approach represents.

Summary. With discussions on-going in the EU on the climate and energy policy framework to 2030, it is timely to assess the reality of climate policy integration into EU energy policy. Such an analysis can lead to lessons for the legislative process for the 2030 package, and even for policies in other sectors and beyond 2030. Climate change is a complex, crosscutting, long-term and global problem. Policymakers acknowledge that integrating climate policy objectives into the elaboration and agreement of measures in other sectors represents one method for striving towards coherent policies that respond adequately to the climate change problem. This policy brief presents the results and policy recommendations from the project “climate policy integration into EU energy policy”.
