In September 2014, KAPSARC hosted a workshop in Paris to explore the “energy for water” component of the water-energy nexus. Energy for water was chosen because it has received less attention in discussions on water and energy, which to date have focused largely on how water is required in the production of different energy resources.
Water and energy form a nexus with agriculture that requires a more integrated analysis. Large quantities of water are used to produce hydroelectricity, cool power plants, stimulate oil and gas reservoirs, and refine petroleum products. Similarly, energy is a critical input for the extraction, treatment, and transportation of water, much of which is used by the agriculture sector. Unsound management of either resource can have an impact on the cost, availability, and sustainability of the other.
The objectives of the workshop were to:
Explore the similarities and differences in countries with respect to managing the energy they expend to provide water.
Describe the energy implications of using different technologies for extraction, treatment, and transportation of water.
Discuss the controllable and uncontrollable factors affecting the potential for countries to make improvements in their energy use for water.
