How wonderful it would be if all countries, at least within Europe, used the same plug. Throughout Europe (not just the EU), earthed plugs have become the norm for as much as decades past. The so-called Schuko design or at least a close similarity appears to have very widespread favour, including in Spain. There are nevertheless different plugs in use and overall there is quite a variety on the go. The unearthed Euro plug is quite common all over for double earthed devices but sockets are generally earthed. The modern UK type is not in use anywhere else in Europe and worldwide use is basically limited to former and present UK colonies/possessions, but only some. Nobody else has seen the need for a fuse and there is no published evidence to suggest that by itself the UK plug has significant advantages (accidents, etc.) over for example the Schuko - but it is the most complicated. The sheer size of the UK plug is unnecessary and by comparison to the rest the plug is a pain from the consumer/user point of view. There are at least two different designs in use in Europe (earthed Euro and Ticino) which achieve earthing in a compact and user friendly design (and the Ticino is arguably more reliable and safer than all the rest). I read somewhere a good while back that attempts to standardise plugs in Europe date back to pre WWII - that has not come about due to obviously deliberate attempts of many countries to be different and thus reluctance against uniformity. Pretty much all the plugs being used do the job adequately, they just do it differently. To suggest that the UK plug should have been adopted elsewhere is quite unrealistic and always was very unlikely. One can get used to it but it is an unhelpful design.
