As can be seen in the “no conversion” case, the coal industry requires inputs from industries X and Y. In the “total conversion” case, the solar energy industry will require inputs from industries W and Z. The “partial conversion” case is simply an example of an economy, using both types of energy. An important input into the above analysis is the rate at which final demand will change. A very rough estimate could be inserted here, possibly by asking the relevant people; or an alternative course would be to simulate the entire systems for different rates of adjustment. This path would provide useful information about the effects on different industries from a shift to the SSPS as the source of power. It must be noted here that the use of solar energy will be affected not only by a shift in final demand, but also by changes in the production technology reflected in the matrix of interindustry linkages. Changes in their matrix will also have to be considered. As individual industries shift their sources of power and as resource inputs to the energy sectors differ, the industry impacts will be reduced. These will produce new demand patterns for material, and capital and labor resources. Along these same Unes, therefore, an analysis should be presented on the demand for labor as an input to production. Since different energy-producing industries have varying labor requirements, the substitution of one for another will affect the total demand for labor in the economy. While excess labor will eventually find new jobs, there may well be specific programs which the government could institute to ease the adjustment.
