Is it? I thought it meant no harm to the environment. If the charging station is powered by solar energy, I don't see how using the otherwise wasted energy wrong.
It's all about scale.
Of course some solar panels are not going to harm the world. But what if we need, lets say, 1% of the earth covered with solar panels?
If it's hard to predict the effects it might be dangerous.
