CEE $250$ In$-$class exercise #$4-$ Wed Feb $7,2024$ Problem Solving $-$ Carbon Offsets & Sequestration

Determine the following:

How many acres of trees are needed to sequester the annual $C{O}_2$ emissions for a typical U$.$S$.$ household for the following conditions? $[$Use Table $1$ and Data source A$]$

Northeast $(25$ year$-$old white$/$red pine$)$ o Pacific Coast $(50-85$ year$-$old

Ponderosa pine$)$ o U$.$S$.$ average

How much land $($acres$)$ would a $12\%$ efficient PV system require to generate enough electricity for the average annual U$.$S$.$ electricity needs in the following locations? $[$Use Data source B$,$ Table $2$ and Data source C$]$ o New York City, NY o Portland, OR

Calculate $C{O}_2$ savings $(/Mc-$acre$)$ for switching to the PV system $($above$)$ at the New York City location. Note: you'll need to determine the $C{O}_2$ emission rate $(C\frac{O}{\frac{?}{?}}kWh)$ using the state data in Table $3.$ This was completed for Alaska as an example.

From part $1,$ write the carbon sequestration rate $(-$acre$)$ for the northeast location. $($No calculation needed $-$ find the correct value from Table $1)$ why?
