C. A power plant takes steam left over after electricity production and uses it to heat buildings.

Explanation:

Cogeneration is defined is defined as the joint production, in a sequential process, of electricity and useful thermal energy from a single energy source.

-Simple put, electricity and heat are made at the same as with C, where left over steam is used to heat buildings.
