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 CO2CO_2/kWh.

Procedure

  1. Calculate the community's annual CO2CO_2 emissions in metric tons.
  2. If a nearby forest can sequester 5 tons of CO2CO_2 per hectare per year, how many hectares of forest are needed to completely offset the community's electricity emissions?
