Systems are called real-time systems, if the correctness of the system does not only depend on the correctness of the system output but also on whether the output is delivered on time.

From treatment plants to hot showers, emissions from water use in the U.S. are equal to 50 million cars driving around for a year. In The Washington Post, staff writer Tik Root consults different experts to learn about ways to reduce our water consumption. He also speaks with Leiden environmental scientist…

For Leiden University’s operations, sustainability is an important topic, especially looking at the CO2-footprint, renewable energy and the greening of buildings.

Over the past century, the world population has grown exponentially, as has our need for energy and raw materials. If we wish to continue to live prosperously in the future, we have to radically restructure our economy and consumption. Scientific research shows us how to do this.

In order to analyze the challenges linked to data use in the context of nexus governance, Giest & Mukherjee use a policy design lens and more specifically the perspective of organizational policy instruments to look at the Mediterranean region.

The Institute of Environmental Sciences has carried out and participates in several projects that deal with the analysis of energy systems.

How do societies move forward with sustainable, effective and efficient management of Earth's water resources?

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

Twenty years from now, the world population is estimated to be around 8.7 billion people, compared to the current 7.3 billion. In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables,…

The transition to new and renewable energy sources should be completed by 2050. Researchers in various disciplines at Leiden University are conducting unique research that will help us make this transition and reduce CO2 emissions.

Marc Koper’s research focuses on electrocatalysis and electrochemical surface science for sustainable energy and chemistry. Reactions of interest are the redox reactions of the oxygen/hydrogen cycle (water oxidation, hydrogen evolution), the carbon cycle (reduction of carbon dioxide, oxidation of small…

Leiden University is in the process of transitioning from one energy source to another: fossil fuels have to make way for sustainable energy from sunlight, water and wind.

We need drinking water for making tea and coffee, but not for flushing the toilet. By reducing the consumption of clean water, Leiden University is helping to minimise the environmental impact.

On 27 January 2022 Tjahjono Prasodjo successfully defended a doctoral thesis and graduated.

This book provides the answers, presenting clear insights into the current state of affairs and exploring future prospects.

Understanding the water use of power production is an important step to both a sustainable energy transition and an improved understanding of water conservation measures. However, there are large differences across the literature that currently present barriers to decision making.

While ecosystems have concrete benefits for human society, these benefits are typically overlooked in decision-making.

Energy transition will entail the construction of large numbers of new energy installations. Such construction projects may meet with opposition from people living close by. Assistant Professor Bríd Walsh investigated how the local community can best take part in such projects.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

We would like to present to you a simple guidebook about living a sustainable life as a student in the cities of Leiden and The Hague. Whether you are a first-year student still trying to find your way around or already doing your masters – students wanting to explore more sustainable options and save…

The transition from fossil fuels and the practical changes that this entails make many demands on citizens. Emma ter Mors, a psychologist and lecturer at Leiden University, is researching the factors that contribute to public perception and acceptance of new energy technologies.

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

The main research theme in the group of Dennis Hetterscheid is to understand and mimic bioinorganic multi-electron processes that are relevant to our future energy infrastructure. Reduction of protons generates hydrogen that can be used as a chemical fuel. Alternatively to gaseous hydrogen, the reduction…

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

Twenty years from now, the world population is estimated to be around 9 billion people (now 7.8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables, water and energy.…

Human activity, such as pollution, may disturb the balance of living water systems, which has consequences for biodiversity, but also for other functions such as water purification. Leiden University maps living water systems using the most advanced technologies.

The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

The energy transition is a complex transformation process that is not only about technology -moving towards renewable energy sources-, but even more so about societal and institutional change. The energy transition requires and provides opportunities for actors to take on new roles.

This project investigates ancient water management of streams, springs and runoffs on the archaeological site of Monte Albán, Mexico, as a means to contribute with different stakeholders in the development of sustainable solutions to water problems today such as floods and scarcity.

Astronomical observations of cold regions in the universe show a rich inventory of ices. Part of these ices may end up on planets like our own, but in that journey they will be exposed to considerable amounts of radiation.
