Enabling Variable Renewables and Driving Down Emissions, with Electric Vehicles

At a media frenzied event last March, electric car manufacturer, Tesla, unveiled its Model 3. Priced to compete with conventional fossil-fuelled vehicles, it attracted over 325,000 reservations within a week.  The hype built around this vehicle, and several other fast and slick electric cars, is but a symptom of a much larger and growing movement across the motor vehicle industry, to cut the transport sector’s oil addiction and switch to electric power.

Globally the stock of electric vehicles is on the rise, and in 2015 more than one million electric vehicles were on the road. That number grew to more than two million in 2016, with China, the US, and several European countries leading the way in uptake.

Sustainable Flight with Biofuels

If the aviation sector were a country, it would be the eighth-largest emitter of greenhouse gases in the world — using planes and helicopters to move people and cargo around the world produces around two percent of the world’s planet warming gases. In 2010, carbon dioxide (CO­2) emissions, the  primary contributor of human-caused climate change, from international aviation amounted to 448 megatonnes (Mt). The International Civil Aviation Organisation has forecasted that CO2 emissions from the aviation sector will increase to the range of 682 Mt to 755 Mt by 2020, and could even be as high as 2,700 Mt by 2050, a six-fold increase from 2010 levels, if nothing is done about it.

So what can be done? What’s the environmentally responsible solution for aviation, and how can emissions be reduced, short of removing planes from the skies? Continue reading Sustainable Flight with Biofuels
