Physics and energy go hand in hand. But what state is the world currently in and where is it headed? This infographic quickly describes one possible direction for energy generation…

 

Alternatively, there are other forms of attaining nuclear fusion without an energy-intensive reaction. The Star Scientific organisation in Sydney, Australia, is currently working towards fusion reactions that are catalysed by muons (subatomic particles similar to electrons), that only produce Helium gas as a byproduct – no radiation! Amazing!
