Solve the all given parts of given problem:

Problem: Consider the power required to drive the hydrologic cycle, assuming that annual global rainfall averages 1 m across the approximately 5.1 × 10¹⁴ m² of earth's surface. Consider the following data: Latent heat of vaporization = 2465 kJ/kg for water at 15ºC; Incoming sunlight absorbed at 168 W/m² at the earth's surface. Also in 2008, total worldwide energy consumption was 474 exajoules (474×10¹⁸ J = 132,000 TWh). This is equivalent to an average energy consumption rate of 15 terawatts (1.504×1013 W).

Part I: What is the energy required to drive the hydrologic cycle?

Part II: How does this compare with incoming solar radiation?

Part III: How does this compare with world energy consumption?

Please keep answer short and simple and please no copy and paste.
