The sun
the inner core
there are many reasons for heat in earths crust. like the friction between rock masses during movements of earths crust. there may also be heat left over from the original heat of earths interior. but the main reason for heat in earths crust is radioactive elements. they give off energy that can be absorbed as heat. some radioactive elements include uranium, thorium, and a form of potassium.
the ocean has a higher heat capacity
The major source of the earth energy is solar radiation, or more bluntly light and heat from the sun. Heat creates the differences in air masses and is responsible for most of there movement.

the mantle plume There are two source of heat in the earth's interior. The main two sources are fire and breathing heat.

What needs a heat source to begin evaporating. Normally the sun is the heat source that evaporates water on the earths surface.
the ocean has a higher heat capacity
Nuclear energy is used as a source of heat. The heat from the reactor is used to heat up water and the steam moves a turbine that generates electricity. It's the same principal with a coal power plant, only the source of heat is different.
