Ohio Electric Data

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.
