All of the newer homes, even though they are all electric, have at least one combination CO/smoke detector.

Are they necessary? Well, that is an opinion. I personally feel that for the low cost, etc, and for what they do it is never a bad idea to have one. As a former career firefighter I have seen a few times, even in an all electric home cases where they saved lives.

More then once, an elderly person drove their car into the garage, closed the door and left it running. Another time workers next door were using a gas powered generator and the wind blew toxic amounts of CO into a neighbors home. The ppm was well over 100....a deadly amount.

So basically, in an all electric home you may never need one....but if you are in a position of upgrading the ones you have, the addition of one would not hurt.....especially since they now make combo ones, etc.
