The Value of a Free Ride On Public Transit? Not Much, According to New Study

On Jan. 1, 2013, Tallinn, the capital of Estonia, became the first European capital to extend free public transport to all of its 430,000 residents. One of the main drivers was mobility for all, but does it really work? Is making public transportation free actually increasing mobility? While it might take some time to evaluate the economic impact of this change, a new study of three researchers from the Swedish Royal Institute of Technology provides an initial outlook into the changes in ridership following the introduction of free rides.

Electric Vehicle Performance Found to Slide in Winter

Hybrids don’t do as well in winter for reasons ranging from modified winter gasoline formulations, to increased stationary warm-up time, to increased heater usage, to reduced battery performance in cold weather. A recent report in MIT Technology Review claims that the situation gets even worse when moving from hybrids to all-electrics. But before we snow on the EV parade, let’s ask how serious these cold weather drawbacks actually are.

Smart Energy Storage Becomes the New Power Source

Fossil fuels have long held an advantage over renewables in that they provide a combined energy source and storage medium in one substance, be it gasoline, coal, oil or natural gas. The fact that you can save it, store it, then use it continuously whenever you need it is a tremendous convenience.

That gap is now being reduced with the advent of combined solar-storage systems. These new systems not only match the capability of fossil fuels, but can actually go them one better. How?
