With nonrenewable sorces of energy getting exhausted Electricity(spl.Wind,geothermal) is definately the way to go....
Electicity is such a convinient form of energy that most of the sources of energy converted to electrical form & then used...
But the major LIMITATION with Electrical Energy is the difficulty faced in Bulk Storage (Although batteries can store a meagre amount of power)...
So the need of the hour is to develope such device\technology which can store Electric power in bulk but still be compact in size...
May be we can convert Electricity into some other form of energy which can easily be stored and re-used wenever & whereever required....
May be Superconducting materials can help ???
If ever possible, it would make the Electricity Export across the continents possible, ofcourse without physicall conections....
& then just immagine .....
Waiting some INNOVATIVE Ideas...........
