Yes but that 98% reduction in electricity (do you have a source for that number?) is on the carrier side, not the cell 
phone side.  There is also a good chance that the carrier router is going to consume the same power either way.

CAUTION: This email originated from outside of the organization.
fun fact I forgot to mention: if you use ipv6 on cellphone connections, your site loads more than 2% faster and uses 
less than 98% as much electricity, due to avoiding the expensive and computation-hungry NAT process itself, as well as 
not needing to be physically routed to that big centralised server and back. So if you care about 2%, you'll use IPv6.
