Towards sustainability in water-energy nexus: Ocean energy for seawater desalination

Seawater desalination using renewable energy sources

The origin and continuation of mankind is based on water. Water is one of the most abundant resources on earth, covering three-fourths of the planet’s surface. However, about 97% of the earth’s water is salt water in the oceans, and a tiny 3% is fresh water. This small percentage of the earth’s water—which supplies most of human and animal needs—exists in ground water, lakes and rivers. The onl...

Modeling of water, energy, food nexus in Varamin city and evaluating its social and environmental sustainability

Population growth, growing scarcity of freshwater resources and food security have convinced all operators that spending large sums of money on cross-cutting responses to water, energy and food needs, especially in the face of climate change and global warming, is unreasonable.According to the latest classification of the International Geographical Organization, Iran is located in the category ...

The Energy-Water Nexus: An Analysis and Comparison of Various Configurations Integrating Desalination with Renewable Power

This investigation studies desalination powered by wind and solar energy, including a study of a configuration using PVT solar panels. First, a water treatment was developed to estimate the power requirement for brackish groundwater reverse-osmosis (BWRO) desalination. Next, an energy model was designed to (1) size a wind farm based on this power requirement and (2) size a solar farm to preheat...

The nexus of food, energy, and water.

The Earth's population is expected to exceed 9 billion by 2050, posing significant challenges in meeting human needs while minimally affecting the environment. To support this population, we will need secure and safe sources of food, energy, and water. The nexus of food, energy, and water is one of the most complex, yet critical, issues that face society. There is no more land to exploit, and t...
