Final answer:
Some relatively easy biomass sources to develop include lumber mill sawdust, yard waste, and livestock manure. These sources require minimal infrastructure and can contribute to reducing waste and generating renewable energy.
Step-by-step explanation:
When considering the easiest biomass sources to develop, we need to take into account transportation costs, ease of collecting the resource, and the infrastructure required. Based on these factors, some biomass sources that would be relatively easy to develop include:
- Lumber mill sawdust: Since sawdust is a byproduct of lumber production, it is readily available and can be collected easily.
- Yard waste: Yard waste, such as grass clippings and leaves, can be easily collected from residential areas and used as biomass.
- Livestock manure: Livestock manure can be collected from farms and used as biomass, providing a source of renewable energy.
These biomass sources require minimal infrastructure and can contribute to reducing waste and generating renewable energy.
