Why is there a difficulty in the world to discover new energy sources? That is long lasting, eco-friendly, and highly efficient. We've progressed in many many fields but I find this field being the least... I've been thinking a lot about this, since in the future I'm specializing in this field... What do you all think of the current energy sources? And if possibly something was discovered in the future that has the potential to be the best source compared to all the others... Would it be the most used? + What do you all think of the current alternatives, can they really meet our demands in our world?
