The amount of water used to produce steam. This metric only applies to ecosystems that produce steam.
Water used making steam = steam production * steam recycled * water content of steam * area of steam producing ecosystems (e.g. cogeneration plants)
Used to calculate: steam, sewage from people, leaky pipes and graywater recycled
Depends upon:
—Parameters: proportion of steam recycled and water content of steam
—Other metrics: ecosystem area and steam
