Hello Richard,
Yes the moon distorts the earth but there is only very weak evidence of increased earthquakes associated with the lunar tides. When the earth and moon eventually become orbitally locked, way in the future, there will be even less of an effect.
According to Wikipedia
the current energy loss is due to the oceans sloshing around and has a value of about 3.3 TeraWatts.
