CREATE TABLE table_240 ("Power Source" CLOB, "Number of Generators" FLOAT, "Power Capacity  ( GW ) " CLOB, "% of total Capacity" CLOB, "Capacity factor" CLOB, "Annual Energy  ( billion kWh ) " CLOB, "% of annual production" CLOB)

What is the % of total capacity when the generators is 4048?
SELECT "% of total Capacity" FROM table_240 WHERE "Number of Generators" = '4048'
SELECT "% of total Capacity" FROM "table_240" WHERE "Number of Generators" = '4048'
