Solved Problems
Calculating impacts of global emissions
Problem 1: Carbon Footprint Calculation
A small community consumes 10,000 MWh of electricity annually. The local power grid relies heavily on coal, resulting in an emission factor of 0.85 kg /kWh.
Procedure
- Calculate the community's annual emissions in metric tons.
- If a nearby forest can sequester 5 tons of per hectare per year, how many hectares of forest are needed to completely offset the community's electricity emissions?
