"That shows how ridiculous a 27% target for 2030 is"
Yeah well, if your country has plenty of wind coming from the ocean and you are not a big industrial nation with a lot of energy demand, then 27% seems to be a low goal...
That can’t be right....

Well shit.
If Portugal reaches 27% of energy consumption from renewable sources that's not nearly as significant in terms of absolute energy consumption than when say France or Germany reaches that goal.
Both of these countries don't have a lot of naturally occurring phenomena or places that lend themselves to hydroelectric or geothermal energy production. So, they have to resort to ways that work everywhere but are comparatively more expensive or difficult to implement.
So, while countries like Portugal or Iceland reaching such goals certainly is commendable the 'battle' will be won elsewhere.
