Global carbon emissions have been flat for three years now

Ontario Power Generation Nanticoke Generating Station coal power plantGlobal efforts to reduce greenhouse-gas emissions may be starting to pay off, suggests a recent study. Last month, scientists released an assessment that suggests global carbon emissions did not increase significantly in 2016. That makes this the third year in a row that carbon emissions have remained flat. DON'T MISS: Renewable energy growth...

2017 Toyota Prius Prime: gas mileage, electric range review

2017 Toyota Prius Prime, Catskill Mountains, NY, Nov 2016The 2017 Toyota Prius Prime turned out to be a better plug-in hybrid than we had expected when we drove it around sunny Ojai, California, on the press launch in October. It's a viable competitor to the second-generation Chevrolet Volt plug-in hybrid, though the Volt has an EPA-rated 53 miles of electric range to the Prime's 25 miles. Now we've had...

The Chevy Bolt EV requires ZERO maintenance

Not only do electric vehicles cost literally cents per kilometer to drive, but they also make routine car servicing a thing of the past. The maintenance schedule for Chevrolet's soon to be launched Bolt electric hatch back comprises tires rotation every 12,500 km (7,500 miles) and that's about it until a coolant system flush @ 240,000 km (150,000 miles). If an accurate wheel alignment accompanies every new set of tires you can effectively skip rotation which means the Bolt practically requires absolutely zero maintenance.

And that's only the tip of the iceberg. What goes unsaid is that in EV applications electric motors practically last forever. The international standard for rating motor insulation is based on a half life of 20,000 hours. For every 10c increase in insulation rating life expectancy doubles. For example, a class H (180c) motor that runs at 150c, the insulation systems would lose half it's mechanical strength after 160,000 hours. Power electronics components such as those found in motor inverters are typically rated at up to 100,000 hours.

To put that into context, with average annual motoring of 15,000 km @ an average speed of 60 km/h, a typical EV motor will comfortably cover a minimum 1.2 million kilometres, or 80 years of reliable motoring. No wonder dealerships hate selling EVs!
