'resource-heavy' originates from the combination of 'resource' and 'heavy', where 'resource' refers to available assets and 'heavy' implies a large amount or burden.

The term 'resource-heavy' evolved from the need to describe systems or processes that require substantial resources, combining the words 'resource' and 'heavy' in modern English.

Initially, it meant 'requiring a lot of resources', and this meaning has largely remained the same in modern usage.
