Our municipality likes to boast that our light rail rapid trains are 80% wind-powered. It's the wind energy that the city has purchased and is fed into the general local power grid.

To be completely carbon neutral for several years, would be to me, more physically demanding UNLESS one can purchase solar or wind energy at reasonable rates /have equipment installed in home.

Nevertheless it's encouraging that some municipalities have some pathway systems and their public parking lots lit by solar panel lighting fixtures. Every step counts and helps that a municipality takes steps, since its residents benefit directly/can see use of some alternative energy sources.
