A great way to make transport more environmentally sustainable is to shift to public transport. And what makes that even better would be the public transport to be powered by renewable sources as well.
That’s just what Sydney trains have done with an announcement of a green energy deal.
Investing in green powered public transport is a far better idea than sinking massive funds in self-navigating cars. Both in investment return, transport efficiency and environmental efficiency. It’s a far better idea and closer to its goals.
