Energy from the Desert

This new report from the Photovoltaic Power Systems initiative is the last in a series of publications presenting the results of fifteen years of activity and research on very large scale PV generation systems.  The report shows how very large scale solar electricity generation provides economic, social and environmental benefits, security of electricity supply and fair access to affordable and sustainable energy solutions.  Download here

Use of variable renewables as flexible resources to support grid operation - workshop

‌The energy technology initiatives on smart grids and photovoltaics will join forces in a joint, free-of-charge workshop to examine the use of variable renewables as flexible resources to support grid operation and power transmission and distribution interaction. The event will take place at the Austrian Institute of Technology on 18 May and will be a  good opportunity to learn about the TSO-DSO interaction in other countries and discuss future developments. More...

Collection of solar energy and architecture case studies

A free online database of 50 projects from 11 countries highlights how active and passive solar can decrease energy demand.  Visit the Solar Heating and Cooling initiative website to download the reports.  

Modeling, Design, and Optimisation of Net-Zero Energy Buildings

This publication, jointly developed by the Solar Heating and Cooling and Buildings and Communities initiatives presents advanced modeling techniques and in-depth case studies to aid designers in optimally using simulation tools for net-zero energy building design.  Learn more about this publication and others developed under the same project on the Solar Heating and Cooling publications page.   

Turkey to host 4th Solar Heating and Cooling Conference 

The 2015 Solar Heating and Cooling for Buildings and Industry conference will take place in Istanbul, Turkey from 2-4 December. Jointly organised by the Solar Heating and Cooling Initiative and the European Solar Thermal Industry Federation, the conference programme will bring together the latest developments in solar heating and cooling and highlight local market success.  Visit the conference website.       

Integration of Variable Renewables

This report from the Renewable Energy Technology Deployment Initiative analyses the issues and challenges of the integration of variable renewables energy technologies into electricity grids.  Volume I outlines the background and methodology behind the study and key findings, while Volume II gives detailed information on case studies of 10 jurisdictions around the globe.  Both volumes and a PowerPoint presentation can be downloaded here

Bioenergy News

The February 2015 newsletter from the Bioenergy Initiative features an editorial on the recent workshop on Land Use and Mitigating iLUC, and highlights of other activities, publications and forthcoming events. Download from their website here

South Africa to host SolarPACES 2015 

The 21st edition of the SolarPACES conference will take place in Cape Town, South Africa from 13-16 October 2015.  Conference host, the SolarPACES initiative, has teamed up with the  Southern Africa Solar Thermal and Electricity Association, and the European Solar Thermal Electricity Association to provide an opportunity for industry, research, political and financing stakeholders and experts to share insights into recent R&D activities and new developments in concentrating solar power and chemical energy systems.  Deadline for abstracts is 10 April.  Visit the conference website.  

Next generation policy instruments for renewable heating and cooling in the commercial sector

This report from the Renewable Energy Technology Deployment Initiative analyses current patterns of use of renewable energy sources for heating and cooling in the commercial sector, and provides evidence-based policy recommendations with a focus on existing buildings.  Download the report from their website here

Consenting Processes for Ocean Energy 

A new report from the Ocean Energy Systems Initiative summarises several aspects of the consenting process for ocean energy, based on information provided by the inititiative's membership.   The term 'consenting process' is used to describe all of the consents or permissions necessary to deploy a device or array of devices in the sea and is considered a critical barrier for industry and future progress of the sector.  Download the report from their website here.      

Solar Heating and Cooling Award goes to pioneering French solar municipality

This year's 2014 SHC Solar Award, awarded by the Solar Heating and Cooling Initiative has been presented to the French city of Montmélian (Savoie), a solar thermal pioneer for more than thirty years.  The Mayor received the award on behalf of the city at the International Conference on Solar Heating and Cooling for Buildings and Industry held in Beijing, 13-15 October.  More...    

Long-term R&D needs for wind energy till 2030

Long-term Research and Development Needs for Wind Energy for the Time Frame 2012-2030 presents the R&D priorities identified by the Wind Initiative members and operating agents of the different research tasks and will be used to identify areas for co-operation to mutual advantage. Other research organisations may also find this document useful in setting their own research agendas to advance wind energy technology. Download here
