All countries all over the world are seeking and having a real eager to find as much as they can of energy sources, it doesn't matter for them either they are non-renewable sources - Fossil Fuels - like petrol, Coal or Gas or renewable sources like Sun Radiations, Wind or Waterfall.
They are seeking and seeking hardly to find them in order to use them in so many different forms, just imagine with me if there are no energy sources at all.............................we will stop calling Paris as the light city, transportation issue will become horrible & our harvest or food will be decreased dramatically and then the starvation, famine and drought will begin.
Actually in my opinion that there are some countries - somewhere in the world - are doing like other countries do "which is seeking and looking for different sources of energy" but while they are doing that they are wasting the most important and OBVIOUS source of energy which is (People) themselves, that is why Japan is number one in technology and believe me when I tell you this, if you make a comparison about having energy sources between Japan and for example Egypt, Iraq, Iran, South Africa or Venezuela, you will find out that the other countries are full off different energy sources and Japan has nothing, but the brilliant mentalities of its people.
On the contrary you will encounter with some restrictions which typically should stop Japan from growing in all fields of economy like (The small land space - Her Tsunami - Earthquakes every now and then - Volcanoes - Nuclear Bombs on Hiroshima and Nagasaki - Huge Mountains everywhere), and yet Japan is considered one of the most civilized country in earth planet.
And here it is China which I'm used to call it (The World Factory), if we consider that the huge population is a problem therefore china should be the first country suffering from poverty, and is that true? of course not China is one of these countries which having the strongest economy in the whole world.
Believe me any non-renewable or renewable energy sources is NOTHING and I mean NOTHING, without the human being, so stop listening to the media which is telling the audience that the huge population is a problem, it could be a problem - I confess - but only if we waste it and never look at it, but in my opinion people means Investment.
