This might make sense for large scale solar farms, since the integration of PV would allow the overall price of power to be lower than CSP alone, while CSP would be able to compensate for the rapid output changes from PV that occur whenever a cloud passes over, as well as producing power at night, or shifting it ot peak afternoon periods.
Overall, the air freight pounds are expected to grow at a modest 2-3% annual rate as the integration of world economies over time will increasingly drive movement of small shipments directly from the point of production to the consumer.
