Open Data Sources

IRENA World Atlas:

Just like Google map, you can browse the specific locality on this world atlas and look for global solar irradiation, wind speed and data related to renewables like Hydro, Bio-Energy, Marine and Geo-thermal.


Energy Data from all EU Countries (Datasheets):

Shared by Federica Tomasini, this webpage from European Commission provides updated energy statistical datasheets  for all EU countries. it is particularly helpful in finding the energy mix of the countries according to production sources and consumption classes.


openmod - Open Energy Modelling Initiative:

Open models and open data will advance knowledge and lead to better energy policies. Open up energy models improves quality, transparency, and credibility, leading to better research and policy advice. 


Live CO2 emissions of the European electricity consumption:

This website shows in real-time where your electricity comes from and how much CO2 was emitted to produce it. It also take into account electricity imports and exports between EU countries.


Power Modelling Data Source:

This is a list of primary data sources that are helpful for power system modeling of Europe. For other open data projects, click on heading and visit the link.


GeoDH Map:

This  system presents  the  geothermal resource assessment and highlights the areas where potential for geothermal district heating exists. Based on currently available information in terms geological data,  already operational district heating systems, and heat demand, it shows the  potential in the 14 project countries: Italy, France, Germany, Netherlands, Ireland, United Kingdom, Slovakia, Slovenia, Czech Republic, Romania, Bulgaria, Poland, Denmark, and Hungary.


EU Building Stock Observatory - European Commission:

The EU Building Stock Observatory monitors the energy performance of buildings across Europe. It assesses improvements in the energy efficiency of buildings and the impact of this on the actual energy consumption of the buildings sector overall.


Berkeley Earth:

With courtesy of gaditya1996, Berkeley Earth tool for global mapping of air pollution is added. The website features a real-time data on air pollution in various parts of the globe.  Most of the Europe is covered in the map with exception of Ireland, Denmark, Italy, Greece, Ukraine, Belarus and parts of Spain, France and Scotland.


PV Related Data Sources and Calculation Tools

Photovoltaic Geographical Information System:

This interactive tool gives information of Performance of Grid-connected PV, Monthly global irradiation data, Average Daily Solar Irradiance and Stand-alone PV Estimation of any area in EU.



Constructing building with a customizable size PV modules integrated in the opaque part of the building skin.


Sustainable by Design Tools:

This voluntary site offers a number of sustainable building design tools which includes; SunAngle, SunPosition, Sun Path, windows overhand design, window overhand annual shading analysis, window heat gain and most IMPORTANTLY hourly solar panel shading for given longitude and latitude.


PVWatts Calculator(NREL USA):

Shared by Robert Pleticha, PVWatts application is an interactive interface to rapidly utilize the PVWatts calculator. The PVWatts calculator is a basic solar modeling tool that calculates hourly or monthly PV energy production based on minimal inputs.


Energy/Power Modelling Tools

Long-range Energy Alternatives Planning LEAP:

People from KTH are well aware of this software and all of KTH fellows have almost used it. LEAP, the Long-range Energy Alternatives Planning System, is a widely-used software tool for energy policy analysis and climate change mitigation assessment developed at the Stockholm Environment Institute. The license is free for use by a student in an accredited academic institution (college, university or school). May only be used for the student's own personal studies (degree, masters, PhD). Any use of LEAP for consulting purposes requires a paid license (see below). Post doctoral researchers based in industrialized countries should obtain an academic license.


Model Management Infrastructure (OSEMOSyS):

Energy System Modelling and Analysis of countries and regions.



General purpose, MATLAB compatible scientific programming language. Seen by many as its Open Source alternative, runs most of MATLAB scripts without any change. Can be either used with a graphical or a command line interface, and provides extensions for particular case scenarios managed through an integrated package manager.



An open source MATLAB package for power flow calculations. Mostly used in calculating power flows in (meshed) transmission networks. It has many functionalities, as it evolved over time yet it is easy to use as the user simply needs to define a struct which includes matrices for bus, generation and branch information, (you might need to include generation-cost information, but if you are only interested in the power flow just put in random numbers). It also comes with a lot of examples for different transmission networks. 


System Advisor Model SAM (NREL USA):

Shared by Robert Pleticha, The System Advisor Model (SAM) is a performance and financial model designed to facilitate decision making for people involved in the renewable energy industry i.e project managers and engineers, policy analysts, technology developers and researchers.


SGAM Toolbox:

The SGAM-Toolbox aims to be a little help for architecting Smart Grid Systems in reference to the Smart Grid Architecture Model (SGAM) as introduced by the “Smart Grid Coordination Group”. 


Modelling Tools for Sustainable Development | UN-DESA:

The website introduces practitioners to these tools, provides and interactive platform for policy analysts, and, to the extent possible, it makes available the data and model codes to promote further research and policy dialogue. 


Energy Plus Software:

EnergyPlus™ is a EnergyPlus is free, open-source, and cross-platform, whole building energy simulation program that engineers, architects, and researchers use to model both energy consumption—for heating, cooling, ventilation, lighting and plug and process loads—and water use in buildings.


RetScreen - Energy Management Software:

Another contribution by Elie NajemRETScreen is a Clean Energy Management Software system for energy efficiency, renewable energy and cogeneration project feasibility analysis as well as ongoing energy performance analysis.


Energy Related SME Development Opportunities 

Horizon 2020 Energy Efficiency data hub:

The Executive Agency for SMEs has developed an interactive tool that generates information on EU funding programmes. For the moment application is available for:

Sustainable Urban/Building Modelling Tools

Tool for Building Energy Performance Scenarios | Global Buildings Performance Network:

This tool enables you to interactively engage with modelled data for three possible energy mitigation scenarios for the building sector, globally and per region, by 2050.


Urban Modelling Interface (UMI) - MIT Sustainability Design Lab:

Umi is a Rhino-based design environment for architects and urban planners interested in modeling the environmental performance of neighborhoods and cities with respect to operational and embodied energy use, walkability and daylighting potential.


Energy Efficiency Education

Schneider Energy University - Energy Education Platform:

With courtesy of Elie Najem, the free educational platform of Schneider Energy University is added. The Schneider energy university has multiple courses categorized under two colleges; Energy Efficiency college and Data Centre college. The courses of energy efficiency college is particularly useful if somebody is interested in attempting Energy Management Professional Certification.
