Water is used for cooling in thermal power plants, hydropower for electricity generation, and extraction for oil and gas production. Transportation is not a major use of water in energy production.

Water footprint is the term used to describe the amount of water required to produce a unit of energy.

Thermal power plants are the largest consumer of water in energy production, accounting for over 80% of total water use.

Water scarcity can increase the cost of energy production, reduce the efficiency of energy production, and lead to power outages.

Using more efficient cooling technologies, recycling water, and using alternative energy sources are all strategies for reducing water use in energy production. Increasing water consumption is not a strategy for reducing water use.

Water-energy nexus is the term used to describe the relationship between energy and water.

Water scarcity, energy scarcity, and climate change are all challenges associated with the water-energy nexus. Economic growth is not a challenge associated with the water-energy nexus.

Climate change increases the demand for water and energy, reduces the supply of water and energy, and makes water and energy more expensive.

Water pricing, energy pricing, and water conservation regulations are all policy instruments for addressing the challenges of the water-energy nexus. Energy efficiency standards are not a policy instrument for addressing the challenges of the water-energy nexus.

International cooperation helps to share best practices and technologies, facilitates the development of joint projects, and promotes dialogue and understanding between countries.

Increased energy security, improved water security, and reduced greenhouse gas emissions are all benefits of addressing the challenges of the water-energy nexus. Increased economic growth is not a benefit of addressing the challenges of the water-energy nexus.

Technology can help to develop more efficient water and energy technologies, identify and manage water and energy risks, and promote sustainable water and energy practices.

Governments, businesses, and non-governmental organizations are all stakeholders in the water-energy nexus. Consumers are not stakeholders in the water-energy nexus.

Consumers can reduce their water and energy consumption, choose products and services that are water and energy efficient, and support policies that promote sustainable water and energy use.
