HAVE YOU HEARD OF?

Electric Vehicles (EV’s) vs. Zero Emission (ZE) Vehicles

Electric Vehicles (EV’s) generally refer to fully battery-electric vehicle (sometimes called B-EV’s). They may also refer to plug-in hybrid electric vehicles (PH-EV’s). There are also the less widely (yet) available hydrogen fuel cell electric vehicles (FC-EV’s).

Incidentally, Zero Emission (ZE) vehicles refer to EV’s that produce zero emissions directly at the tailpipe. Though for a vehicle to truly be considered ZE, we must not only calculate tailpipe emissions, but also, how many emissions are being created to produce & deliver the electricity, fuel cell or petroleum resource used to power the vehicle.

In short, no matter which electrical grid in the world provides your power; B-EV’s create the fewest emissions, then hybrid vehicles and then traditional combustion vehicles. Hydrogen fuel cell powered vehicles create the highest number of emissions (due to the energy required to produce the fuel cells).

SDG SPOTLIGHT:

GOAL 11: SUSTAINABLE CITIES & COMMUNITIES
TARGET 2: provide access to safe, affordable, accessible & sustainable transport
systems for all; notably by expanding public transport and improving road
safety.

IMPACT TIP:
KNOW YOUR GRID:

Do you know where your local power utility comes from? What does it means for your emissions footprint? Understand the carbon intensity of your grid:

  • Ask your provider - what mix of resources do they use? Some American providers have a “green power” option.

  • GHG emissions intensities of electrical grids in 2020 (per kWh):

    • In the USA: 386 grams of CO2e

    • In Canada: 110 grams of CO2e

Why focus on Electrification?
Climate modelling & energy systems assessment studies show that net-zero electricity is pivotal for a carbon neutral world. Attaining a net-zero electrical grid is becoming more attainable. The cost of low-emissions technology has decreased dramatically in the past decade, making it an interesting investment for energy producers & utility providers. Electricity is a widely versatile form of energy that can be used across various sectors. In Canada, about 82% of electricity already is produced through non-emitting forms of energy. Renewable, low-emissions energy sources have not yet been realized to their full potential — creating plenty of growth opportunity in the energy market. Almost 80% of new electricity installed in the United States in 2021 comes from non-emitting sources.

How are we using Electricity right now?
Energy is distributed differently whether it is used in industry, transportation or within the built environment (residential & commercial). Industry uses the most energy of any sector, and only 21% of that energy is sourced by electricity — which has its own emissions footprint depending on location. Electrification of the transportation sector will certainly create increased demand on utility grids. The built environment accounts for 17% of Canada’s GHG emissions as it is presently powered largely by natural gas. Electric heat pumps produce up to 4x more efficient space & water heating than electric baseboards, making them more affordable and an important technological advancement in reducing emissions in the built environment.

What about batteries and storage?
Because most renewable energy resources must be stored (either for later use or for distribution), battery technology is evolving. With an increase in renewable production and electrification, raw mineral development is necessary as well as advancements in battery manufacturing & recycling. Increased lithium-ion battery production has led to an 85% decline in price since 2010. Though battery technology has come a long way, advancements in storage capacity will allow for even more practical electrification. Innovative solutions to battery recycling are resulting in increased access to important minerals, as well as a decrease in physical wastes left behind.
