Exploring bioenergy potentials of built-up areas based on NEG-EROEI indicators

- There are unconventional sources of biomass for bioenergy in urban areas.
- Green roofs, parks, construction sites and domestic wastes are all bioenergy sources.
- NEG and EROEI are useful indicators to compare various sources of bioenergy.
- Bioenergy potential is largely dependent upon existing policies and regulations.
