+) Singapore has a unique private vehicle usage system, based on your day of birth. If you were born on an odd number day you can only drive on odd number days and vice versa for even number days. They also have a very complex parking system which I can't explain.
The Youth will naturally feel inclined to use alternatives to private transport, this will occur at a young age, hence keeping it a habit for the lifetime.

+)Any future electricity power stations installed should be only of renewable energy.

maybe decreasing the non-renewable sector as well.
