If all land area in the US that is used for growing corn for ethanol were used

Question:

If all land area in the US that is used for growing corn for ethanol were used for solar thermal electric plants operating at a gross conversion efficiency of 3%, estimate the total electrical energy yearly produced assuming an average insolation of 200 W/m2. Compare to US energy consumption of roughly 100 EJ, assuming 35% efficiency for 65 EJ of petroleum and coal energy used and 100% efficiency of the remainder.
