Opportunities to Make a Difference

Consider making the leap to an electric vehicle or encourage a friend searching for a new car to do the same!

Buy new or used.

If you're still not sure you want to fully commit, try a lease.

Also consider alternative methods of transportation, like an electric bike for in town trips.

Reason for Hope

The shipping industry has set a course to phase out its greenhouse gas emissions.

The deal came during a meeting of the International Maritime Organization following the planet's hottest day on record.

Targets call for a 20% reduction of greenhouse gases by 2030, a 70% reduction by 2040, and net zero emissions by 2050.

These targets are nonbinding and there is still a need for accelerated action in the industry.

Main Topic

Why buy electric?

  • in the US, cars and trucks account for ~23% of greenhouse gas emissions, with 17% owing to light duty vehicles
  • Globally, cars and trucks account for ~12% of ghg emissions

EV myths

Myth: EV's are just as bad emission-wise as internal-combustion engine or ICE vehicles are.

  • Indirect Emissions (mining, drilling, shipping, manufacturing) vs. Direct Emissions (released while driving)
  • EV's have only indirect emissions, while internal combustion engine vehicles have both
  • Even with indirect emissions included, ICE vehicles are far dirtier than EV's

Myth: EV’s rely on coal/fossil-fuel similarly to ICE vehicles.

  • EV’s far more efficient
  • 87-90% of energy in EV's battery sent to wheels
  • Only 16-25% of energy from ICE vehicles sent to wheels

Myth: Batteries are terrible for environment.

  • Mining impact not the same as climate change
  • Current move to lithium iron phosphate batteries will improve environmental/social impact (no nickel or colbalt)
  • Recycling is possible => eventually, no more raw materials needed

EV buyer considerations

Batteries - most manufacturers are in the process of moving to what's called lithium iron phosphate

  • Tesla has already adopted them, GM, Ford, VW and Rivian are all in the process of moving to them
  • They can handle more charge cycles over the lifetime of the vehicle
  • They loose less of their capacity over time

Tax incentives - there's lots of them. Do your homework

Efficiency - MPGe (miles per gallon of gas equivalent)

  • Larger vehicles are not only less efficient, but building them requires far more resources from the battery to the body
  • Sample MPGe ratings = Tesla Model 3 – 132 (very good), Ford Lightning 70 (fair/poor), Hummer 47 (the worst)


  • Range - winter driving will reduce range as well as uphill driving and headwinds (just like a regular car)
  • Avoid Nissan Leaf - its batteries are air-cooled which leads to poor fast charging performance
  • Non-Tesla cars from GM, Ford and Mercedes will soon be able to use portions of Tesla's super charging network
  • Heat pump heaters are best - resistive element heaters draw a lot of battery power in winter
