Without seeing latest figures i would say yes. Norway would be one of them, the UK another where at times of very high wind speeds would export to France, Ireland and the Netherlands. Costa Rica has a very large amount of renewable energy and so does Brazil because of large hydropower stations and very good bioethanol output.
Renewables are intermittent which means that throughout the day - under certain conditions- you are prone to overproduce. If that is the case- and you have access to a centralised electricity management system, then of'course you can export.
It also depends on your definition of export. If you make biomass pellets and you sell them to a foreign market, then that is exporting renewables isn't it?
