Wind and solar power are the predominant new sources of electrical power in recent years. Portugal’s renewable energy production in March 2018 was 104% of its electricity demand in the same month. By their very nature, wind and solar power, as well as hydro, tidal, wave and other renewable forms of generation are dependent on weather and climate. Modelling and measurement for resource assessment, site selection, long-term and short term variability analysis and operational forecasting for horizons ranging from minutes to decades are of paramount importance.

The success of wind power means that wind turbines are increasingly put in sites with complex terrain or forests, with towers extending beyond the strict logarithmic profile, and in offshore regions that are difficult to model and measure. Major challenges for solar power are notably accurate measurements and the short-term prediction of the spatiotemporal evolution of the effects of cloud field and aerosols. Planning and meteorology challenges in Smart Cities are common for both.

For both solar and wind power, the integration of large amounts of renewable energy into the grid is another critical research problem due to the uncertainties linked to their forecast and to patterns of their spatio-temporal variabilities.

We invite contributions on all following aspects of weather dependent renewable power generation:

• Wind conditions (both resources and loads) on short and long time scales for wind power development, especially in complex environments (e.g. mountains, forests, coastal or urban).
• Long term analysis of inter-annual variability of solar and wind resource
• Typical Meteorological Year and probability of exceedance for wind and solar power development,
• Wind and solar resource and atlases.
• Wake effect models and measurements, especially for large wind farms and offshore.
• Performance and uncertainties of forecasts of renewable power at different time horizons and in different external conditions.
• Forecast of extreme wind events and wind ramps.
• Local, regional and global impacts of renewable energy power plants or of large-scale integration.
• Dedicated wind measurement techniques (SODARS, LIDARS, UAVs etc.).
• Dedicated solar measurement techniques (pyranometric sensors, sun-photometer, ceilometer, fish-eye cameras, etc.) from ground-based and space-borne remote sensing.
• Tools for urban area renewable energy supply strategic planning and control.

This session addresses spatial and temporal modelling of renewable energy systems, both in a prospective as well as in a retrospective manner. Therefore, contributions which model the characteristics of future renewable energy systems are equally welcome as contributions which assess the characteristics of the past performance and characteristics of renewable energies. Session contributions may reach from purely climate based assessments of simulated renewable generation time series to full energy system models used to better understand energy systems with high shares of renewables.

Studies may for instance
- Improve our understanding of how climate data can be used to model renewables
- Show the spatial and temporal variability of renewable energy sources
- Assess the complementarity of different renewable energy sources or locations
- Derive land availability scenarios for renewable energies based on climatic, technical, economic, or social criteria
- Assess past performance of renewables
- Assess past spatial deployment patterns of renewables
- Derive integrated scenarios of energy systems with high shares of renewables

The objective of the session is to provide an insight into recent advances in the field of renewable energy system models. The session welcomes papers dedicated to climatic and technical issues, policy-making, forecasting and real time applications concerning renewable energy systems.

This year we are also publishing a special issue in the ISPRS International Journal of Geo-Information for the session. Authors willing to publish a full paper are cordially invited to visit the website of the special issue for further details: https://www.mdpi.com/journal/ijgi/special_issues/renewable_energy_system

There is a global need for low carbon energy, and marine renewable energy could make a significant contribution to reducing greenhouse gas emissions and mitigation of climate change, as well as providing a high-technology industry. Marine renewable energy includes offshore wind, wave, tidal range (lagoons and barrages), and tidal-stream energy, as well as technologies such as ocean thermal energy conversion, salinity gradients and desalination. Understanding the environment these marine renewable energy devices are likely to operate in is essential when designing efficient and resilient devices. Accurate characterisation of the resource is of clear importance, whilst interactions with the environment, and between other “blue economy” developments, is essential for the development of the industry and marine spatial plans. Indeed, synergies exist when considering the sustainable use of the ocean’s energy, such as multi-purpose platforms integrating marine renewable energy devices and aquaculture.
This session is designed to share information on new research techniques and methods to better understand the resource and the environment, including mapping tools, numerical modelling approaches, and observations. We welcome contributions that will further the development of the blue economy: for example, resource characterization, design considerations (e.g. extreme and fatigue loadings), and environmental impacts. The session will also include studies of impacts, from physical and biological, to societal interactions (e.g. effects to tourism). Research areas are envisaged to include but not restricted to: modelling and quantification of the interaction of the device to the marine environment (e.g. changes in hydrodynamics) as well as on the biology directly; cumulative impacts of large and multiple developments (potentially of differing technologies or marine stressors); new technologies for quantification; management of space; collision; noise.

The transition to a low-carbon economy will require the development of innovative methods to integrate renewable sources of energy while minimizing the additional pressure on closely connected ecosystems.

Hydropower is a mature and cost-competitive renewable energy source, which helps stabilize fluctuations between energy demand and supply. Depending on the relative capacities of the intermittent renewables and hydropower facilities, integration may require changes in the way hydropower facilities operate to provide balancing, reserves or energy storage. Moreover, non-power constraints on the hydropower system, such as irrigation water deliveries, environmental constraints, recreation, flood control and variable social acceptance tend to reduce the ability of hydropower to integrate variable renewable.

This session solicits contributions that describe, characterize, or model distributed renewable energy sources at different spatial and temporal scales that are relevant for planning and management of electricity systems. Special attention will be devoted to the interactions between the energy-water system and the climate and hydrological variables that govern production in space and time. Of particular interest are case studies and other contributions of hydrology and power grid modernization initiatives to understand these complex interdependencies. The development of new modeling approaches to analyze interactions with climate-policy and power grid management options, socio-economic mitigation measures and land use are welcome.

Questions of interest include:
- How to predict water availability for hydropower production?
- How to predict and quantify the space-time dependences and the positive/negative feedbacks between wind/solar energies, water cycle and hydropower?
- How do energy, land use and water supply interact during transitions?
- What policy requirements or climate strategies are needed to manage and mitigate risks in the transition?
- Quantification of energy production impacts on ecosystems such as hydropeaking effects on natural flow regimes.

This session has the support of the European Energy Research Alliance (EERA) that established the joint program “Hydropower” to facilitate research, promote hydropower and enable sustainable electricity production. Further information can be found here:

With an increasing demand for low-carbon energy solutions, the need of geothermal resources utilization is accelerating. Geothermal energy can be extracted from various, often complex geological settings, e.g. fractured crystalline rock, magmatic systems or sedimentary basins. Current advancements also target unconventional systems (e.g., Enhanced Geothermal Systems, super-hot, pressurized and co-produced, super-critical systems) besides conventional hydrothermal systems. Optimizing investments leads to the development of associated resources such as lithium, rare earths and hydrogen. This requires a joint effort for monitoring, understanding and modelling geological systems that are specific to each resource.
A sustainable use of geothermal resources requires advanced understanding of the properties of the entire system during exploration as well as monitoring, including geophysical properties, thermo-/petro-physical conditions, fluid composition; structural and hydrological features; and engineering challenges. Challenges faced are, among others, exploration of blind systems, reservoir stimulation, induced seismicity or related to multiphase fluid and scaling processes.

The integration of analogue field studies with real-life production data, from industrial as well as research sites, and their organization and the combination with numerical models, are a hot topic worldwide. With this session we aim to gather field, laboratory and numerical experts who focus their research on geothermal sites, to stimulate discussion in this multi-disciplinary applied research field. We seek for contributions from all disciplines, ranging from field data acquirements and analysis to laboratory experiments, e.g. geophysical surveys or geochemical experiments, and from the management and organization of information to numerical models as well as from (hydro)geologists, geochemists, (geo)physicists, surface and subsurface engineers.

Characterisation of geothermal energy systems requires advanced understanding of the dominant processes and properties of the geothermal systems. The aim of this session is to offer a platform to present and discuss the use of modeling, analogue and numerical, for the development of geothermal energy. Theoretical, observation, experimental, analogue, and numerical models offer the support to the development of concept and applications to achieve a sustainable and efficient recovery of geothermal energy. All methods have their strength and offer the possibility to develop the understanding of specific aspects of the geothermal system.
All enthalpies of geothermal energy systems can be considered for this session, from new development in small-scale systems to supercritical and from ATES to EGS. The characterization of the geometry of the system, flow and transport properties of main conductive paths and fluid-rock interaction mechanisms and of course heat structure are example of the studies that will be central to this session. Multidisciplinary and multi-scale are most welcome to stimulate the discussion and share/exchange ideas and promote future collaborations within the community.
We invite speakers to present their original research work on theoretical/mathematical models, computer simulation and other experimental/observational aspects. Potential topics include, but are not limited to:
(1) Advanced mathematical models of coupled multi-physical (e.g., mechanical, thermal, hydrological and chemical) processes in geothermal systems based on equivalent continuum, double-porosity, and discrete fracture models.
(2) Lab and field experiments of coupled T-H-M-C processes involved in geothermal production.
(3) Integration of experimental data into numerical models for site characterization, experimental design, data interpretation and uncertainty quantification
(4) Utilization of numerical tools for risk assessment and prediction of potential impacts
(5) Advanced numerical methodologies and models to investigate the hydraulic fracturing process in geothermal systems.

The session welcomes contributions about shallow geothermal energy applications, including traditional closed- and open-loop borehole heat exchangers as well as so-called energy geostructures (e.g. thermo-active foundations, walls, tunnels). Different types of analysis and approaches are relevant to this session, spanning from the evaluation of ground thermal properties to the mapping of shallow geothermal potential, from energy storage and district heating to sustainability issues and consequences of the geothermal energy use, from the design of new heat exchangers and installation techniques to the energy and thermo-(hydro-)mechanical performance of energy geostructures. Contributions based on experimental, analytical and numerical modelling are welcome as well as interventions about legislative aspects.

A large-scale introduction of renewable energy systems (RES) is vital for climate mitigation in emission pathways keeping global temperature stabilization well below 2°C in 2100. At the same time, the United Nations have proposed 17 Sustainable Development Goals (SDGs) to address society’s common global challenges. Among these, increasing human well-being by ending poverty and hunger (SDG 1&2) while at the same time delivering affordable and clean energy (SDG 7), protecting biodiversity (SDG 14&15) and mitigating climate change (SDG 13) are key.

There is an increasing need to assess possible synergies and trade-offs between climate change mitigation and across different SDGs from different RES. A global large-scale introduction of RES may increase the pressure on land resources, including food production systems and other ecosystem services. Land use management is at the core as the effects of introducing different RES on SDGs may vary dependent on spatial location and scale of implementation. Identifying RES deployment strategies that co-deliver across multiple SDGs is vital.

We encourage abstract submissions linking RES deployment to one or more SDGs. In this context, a variety of methods, models and tools are of interest. Examples of these include environmental analyses, life cycle analyses, land use management, regional climate modelling, earth system modelling, energy system models, policy relevant analyses, GIS applications, integrated assessment etc.
