Calculated from USDOE-EERE and Census Bureau data:
Residential electrical usage on Ohio = 13,000 kWh annually per household
Average monthly household bill = c. $108
Annual residential utility income = $B4.36
Total utility income = $B13.55
Ohio rates average about 4.7% below the national average.

Switchgrass Potential
Switchgrass gives 14.4*10^6 BTU/Ton
Chariton used 15,000 Tons to produce 19*10^6 kWh -> 11.4*10^6 BTU/kWh
If 3413 BTU = 1 kWh, Chariton was 30% efficient.
Ohio produces 10.3*10^Tons annually -> 13*10^9 kWh
We only use 420 Tons -> 3% of potential
If Ohio electricity usage is flat at 155*10^9 kwh/yr, and SB221 requires 1/8 of electricity from renewables, biomass could produce 2/3 of what is required.
