Energy Communities are playing an ever greater role in the European renewable energy transition. As instrument for citizen-led transformation, they associated not only with economic and environmental, but also social benefits. However, it is unclear whether Europe deliver on positive impact promise. In this paper, we analyze conceptual background of clarify underlying constructs community empowerment, capital, democracy justice. We conduct a systematic literature review develop overview...
The power grid has become a critical infrastructure, which modern society cannot do without. It always been challenge to keep supply and demand in balance; the more so with recent rise of intermittent renewable energy sources. Demand response (DR) schemes are one counter measures, traditionally employed large industrial plants. This paper suggests consider data centers (DCs) as candidates for DR they consumers able adapt their profile sufficiently well. To unlock this potential, we suggest...
Battery electric vehicles generate a significant share of their greenhouse gas emissions during production and later, when in use, through the energy used for charging. A shift charging behavior could substantially reduce if aligned with fluctuating availability renewable energy. Financial incentives environmental appeals have been discussed as potential means to achieve this. We report evidence from randomized controlled trial which cost-free "green" was advertised via email notifications...
Exploring the vision of a model-based framework that may enable broader engagement with and informed decision making about sustainability issues.
As part of the growing pervasiveness information technology (IT) in global economy, last decade has seen a trend outsourcing IT services, first into traditional data centres, and nowadays more "fuzzy structures" (aka cloud). This led to expansion service business, emergence centre industry - at same time dramatic increase energy consumption centres. Since services provided by centres are typically ruled performance-oriented SLAs awareness is only lower ranking importance for provision...
Demand Response is a mechanism used in power grids to manage customers' consumption during critical situations (e.g. shortage). Data centres are good candidates participate programs due their high energy use. In this paper, we present generic architecture enable between Energy Provider and Centres realised All4Green. To end, show our three-level concept then illustrate the building blocks of All4Green's architectural design. Furthermore, introduce novel aspects Green SDA SLA for...
The existing electromobility (EM) is still in its fledgling stage and multiple challenges have to be overcome make Electric Vehicles (EVs) as convenient combustion engine vehicles. Users Vehicle Fleet Operators (EFOs) want their EVs charged ready for use at all times. This straightforward goal, however, counteracted from various sides:
To develop more powerful, service-specific strategies for reducing IT's carbon footprint, we need complete and widely understandable specifications of services that describe exactly a service's functionality, the level quality it achieves, its environmental consequences. The concept green offers such an approach.
Data centres are important players in smart cities both as IT service providers and energy consumers. Integrating intermittent renewable sources into the local power grid is one challenge future aiming at an based low carbon economy. The project DC4Cities takes up this by offering a technical business related solution for optimizing share of when operating data cities. To end, management options between centre city together with internal adaptation strategies introduced. Finally,...
Power supply needs to match power demand up a certain extent at all times in order provide with sufficient quality and maintain the grid stable state. Matching becomes challenging due steadily increasing an production of based on renewable energy sources. Demand-response management shapes according current availability grid. This paper discusses feasibility benefits integrating data centres into demand-response schemes. Newly designed tariffs (so-called green supply-demand agreements) are...
Data centres, due to their significant energy use and highly automated IT infrastructure, are excellent candidates participate in demand response programs. However, the major inconvenience of today's electricity tariffs between provider its customers is lack flexibility, which renders programs difficult realise. In this paper, we propose a new supply agreement order foster power adaption (i.e. increase/decrease) collaboration data centres. To end, introduce contractual terms based on those...
Data centres are key to a future energy system with high share of intermittent renewable sources. They form the cloud that enables modern life-style and cyber-physical based production; however, fulfilling these tasks makes them fastest growing component IT power demand. In flexibility consumers' demand will be necessary response intermittency supply. Therefore, data as big consumers become one target consumer group integrate their potential into daily business operation.
Given the projected growth in IT over coming decades it is important that supply of, and demand for, computing services be made as environmentally friendly possible. One of key technologies for achieving this will undoubtedly cloud which opens up many new opportunities streamlining way are delivered used. Several research projects have therefore recently started to examine ways improving efficiency infrastructures understanding energy algorithms. However, date these mainly focused on...
Collective, citizen-led approaches to energy systems are key reducing humanity's climate impact. Crucial for their success is the engagement of prosumers, i.e., citizens that produce energy. This paper investigates how best activate identities prosumers participate in peer-to-peer trading. In collaboration with OurPower cooperative Austria, an experimental trial was set up: 8713 households equipped photovoltaic were randomly selected receive one three postcards. Postcards appealed different...
The increasing integration of renewable energies into the electricity system and a fluctuating power demand cause high pressure on today's grid. One contemporary approach to deal with this issue is implementation response mechanisms: In contrary adjusting supply by generation from brown energy sources, side rendered flexible. Data centers are highly suitable participants for due their extremely dynamic infrastructure consumption. Integration data programs offers huge potential benefits...
Increases in peak electricity demands and the growing use of renewable energy --- with associated intermittency variable output present new challenges to service providers (ESPs). ESPs employ demand charges, tariffs response (DR) programs influence consumption behavior consumers partially mitigate these challenges. Due their high load potential flexibility, supercomputing centers (SCs) are increasingly gaining importance grid. This paper presents a qualitative study contracts between SCs...
Abstract Data centres have been the focus of research as candidates for demand response or other side management programs quite some time. However, a complete framework optimising data centre is still missing. This due to complexity integrating more than one power flexibility technology and market flexibility. In presented work, this challenge solved by creating microeconomics inspired optimisation approach that takes view offering ’product’ explicit and/or implicit markets. generic then...
