Its not in the Constitution. It should never have been created. It will be easy to dissolve and should be.
The reason it should not have been created is because it was not specifically enumerated and granted by the States to the Federal Government. Powers not specifically granted to the FedGov were intended to be reserved by the States.
"The powers delegated by the proposed Constitution to the federal government are few and defined. Those which are to remain in the State governments are numerous and indefinite."
James Madison, Federalist Paper 45
"The powers reserved to the several States will extend to all the objects which, in the ordinary course of affairs, concern the lives, liberties, and properties of the people, and the internal order, improvement, and prosperity of the State."
James Madison, Federalist Paper 45
"In the first place it is to be remembered that the general government is not to be charged with the whole power of making and administering laws. Its jurisdiction is limited to certain enumerated objects, which concern all the members of the republic, but which are not to be attained by the separate provisions of any."
James Madison, Federalist Paper 51

Creating the DoE is automatically suspect as a FedGov overreach. FedGov is improperly exercising power over states that it was not granted.
