just a few thoughts


1) energy needs to be a cheap commodity since it is essential to modern life. On earth it will never make sense to have a single source

2) Even though electricity is easily transportable (power lines over many miles) it is not infinitely transportable. Every cable has resistance and that means the further it needs to go the more electricity is lost (at a given voltage), no matter how cool it sounds making electricity in Australia to be transmitted to power a Montreal winter's night dose not make any sense.

3) yes solar needs a lot of space but luckily it can use wasted space. what I mean is that it can be on the roof of a home (like Mario's home) and so no other space is wasted. Now I am not talking about driving on solar cells (that's just nuts) but imagine a light structure with solar cells over parking lots, using the roof tops of sky scrapers......
