Indonesia is experiencing various environmental challenges related to its fast economic growth. Therefore, it is necessary to have measurable and applicable indicators to obtain accurate data and information regarding the costs of adverse environmental impacts arising from economic activities to support…

To generate electricity, power plants use huge amounts of water. In Europe and the United States, generating electricity is accountable for 40% of the total water withdrawal. PhD candidate Industrial Ecology Yi Jin devoted his research to the water footprint of power plants and the impact on the environment.…
