This book in three volumes contains the papers presented at the ninth international conference on Energy Efficiency in Domestic Appliances and Lighting. EEDAL'2017 organised in Irvine, CA, USA by California Plug Load Research Center (CalPlug) at the University of California, Irvine on 13-15 September 2017.

Building on its previous reports, investigating the status of the ESCO market in the EU, the Joint Research Centre (JRC) reviewed the efforts made by Member States to stimulate the market of energy services, and in particular the market for EPC, during the period 2014-2016 and the current size of the ESCO market. The findings in this report show new developments since the last report published by the JRC in 2014 for the period 2010-2013.

The slowdown of renewable energy deployment is a concern and needs to be avoided in the time the EU is aiming higher shares of renewables in 2030. Through a cost-optimal approach the EU ought to double in 2030 the current share of renewables in electricity sector. The important changes in electricity sector and in the related markets have already occurred, bringing to the question on how much these changes are reflected in the European Commission scenarios assumptions and results. 

Climate change is recognised as one of the key challenges humankind is facing. The Information and Communication Technology (ICT) sector including data centres generates up to 2% of the global CO2 emissions, a number on par to the aviation sector contribution, and data centres are estimated to have the fastest growing carbon footprint from across the whole ICT sector, mainly due to technological advances such as the cloud computing and the rapid growth of the use of Internet services.

On 22 June 2016, the CoM Europe and Compact of Mayors announced the formation of the Global Covenant of Mayors for Climate and Energy (GCoM) - as a worldwide coalition of cities committed to fighting climate change. Over time, the Global Covenant of Mayors will work towards ensuring compatible and comparable reporting approaches for signatory cities worldwide.

The Streetlight-EPC project has created demand and supply for Energy Performance Contracting (EPC) in 9 regions by setting up regional EPC facilitation services and supporting projects towards implementation. The facilitation services provided comprehensive support to municipalities (including members of the Covenant of Mayors) and (potential) ESCOs. In the frame of Streetlight-EPC, 30 projects have already been implemented using a variety of EPC models and 10 more with other financing or operational models. In total, 20.4 million Euro have been invested so far.
