Energy efficiency kind of falls under the "performance" category. Just not raw MIPS performance but "performance per watt". What I wanted to say is that the major selling point of RISC-V would be its open-ness rather than anything performance (or power) related. In that respect it has already captured the attention of interested parties, regardless of that the actual performance will be.
