Creating 100% renewable energy is awesome, but having to import a lot of dirty energy from abroad isn’t really helping much on the global scale.
If the power networks are connected, you sometimes have surprisingly little control over it, tbh.
Plus “We need to be self-sustaining in our power production” is a very different thing than getting all the energy you produce to be green. It’s not as simple as “Well just build more wind/solar/tide generators!”, it requires a complete rethinking of how you route and balance your network as even the most energy-producing countries regularly import power depending on current load and network state.
That is to say, don’t belittle an achievement of producing 100% green energy. The other part, no longer consuming any non-green imported energy, is a nearly unrelated problem.
