Not as difficult, but consuming large amounts of energy on short notice is also not trivial.

"connect a resistor to the end of a power cord" is supposed to make it sound trivial, but operating the resistors needed for absorbing the extra power on the grid is a large scale operation with non-trivial safety concerns. Also, you need to own and maintain all that equipment, &c &c.
