Our Public transport to get around the city is great but can be improved. As great as it is to encourage cycling or walking to your destination, most would rather take advantage of the convenience of a car. That's why sustainability should start in a place citizens don't have to sacrifice anything for, public transit. It is already common knowledge that taking the local bus or Skytrain to work, school or even just get around is better for the planet, but there's still ways of improving it. Unfortunately larger vehicles like planes cannot yet run on solar panels but a simple bus or skytrain certainly could. Now of coarse this comes with it's own set of problems mainly concerning funding, as the city often has a tendency to be a bit cheap, but with enough people to back it up this could really happen. Not only would it make public transit more Eco friendly, but would also be setting an example for what other cities could do to start making a difference in regards to sustainability.

Although it is a good idea to make public transport greener, I find that most people including me sometimes either find it inconvenient, as you said, or are just too lazy to use public transport. We really need to focus on mass producing solar powered cars, because most people will use their car pretty much all the time. Although it will be expensive, it will be easier to power a small car with solar panels than a large bus or train. Also, a solar powered train would have a hard time storing energy for times when the sun is not out because of its large size and energy needs. A car would not face that problem because it is smaller with less demanding energy needs.
