There is a perception that reducing greenhouse gas (GHG) emissions is expensive (e.g., buy a Tesla) or requires sacrifices (e.g., don’t fly or don’t eat that hamburger). In the case of e-bikes, this perception is resoundingly incorrect. I bought an e-bike several months ago and have put a couple hundred miles on it (displacing miles that I would have driven otherwise). As I discuss below, the financial and environmental return on investment are excellent. Plus e-bikes are a lot of fun, lower the barriers to riding, and have other benefits for the city and people’s health. Financial ROI So is my e-bike just a toy, or is it a tool with a valuable return on investment (ROI)? I am on track to ride about 700 miles this year, which I otherwise would have driven. Each mile that I’m not driving is saving me money. According to the IRS, it costs 62.5 cents per mile to own and operate a private automobile. This accounts for all the costs like financing, insurance, gasoline, depreciation, ma...
While there are many reasons to reduce the use of private vehicles (e.g., traffic fatalities, expense, accessibility, air quality), in this post I will focus on climate change. In the U.S., 27% of GHG emissions come from the transportation sector, and the largest contributor within that category is cars, trucks, minivans, and SUVs ( EPA ). If SUVs were a country, they would be the 7th largest GHG emitter ( The Guardian ). Climate change is projected to kill many people through heat, drought, flooding, disease and famine. The WHO has called climate change "the biggest health threat facing humanity" and projects 250,000 additional deaths per year due to malnutrition, malaria, diarrhea, and heat stress from 2030 - 2050 due to climate change ( WHO ). Another study projected 83 million excess heat-related climate change deaths (or approx. 1 million per year) from 2020 - 2100 under baseline emissions ( Bressler, 2021 ). The Bressler study projects more deaths than the WHO, which is...
