If Done Right, IPCC Says Revolutionary Changes In Transportation, From Electric Vehicles To Ride Sharing, Could Slow Global Warming

Around the world, revolutionary changes are under way in transportation. More electric vehicles are on the road, people are taking advantage of sharing mobility services such as Uber and Lyft, and the rise in telework during the COVID-19 pandemic has shifted the way people think about commuting. Transportation is a growing source of the global greenhouse gas emissions that are driving climate change, accounting for 23% of energy-related carbon dioxide emissions worldwide in 2019 and 29% of all greenhouse gas emissions in the U.S. The systemic changes under way in the transportation sector could begin lowering that emissions footprint. But will they reduce emissions enough? In a new report from the Intergovernmental Panel on Climate Change released April 4, 2022, scientists examined the ...

Increasing Fuel Efficiency Matters More Than Selling Electric Vehicles, To Make The US Auto Fleet Greener

President Biden has proposed ambitious goals for curbing climate change and investing in a cleaner U.S. economy. One critical sector is transportation, which generates 28% of U.S. greenhouse gas emissions – more than either electric power production or industry. Shifting from cars that run on gasoline and diesel to electric vehicles, or EVs, is a key strategy to address transportation’s contribution to global warming. Industry watchers expect big federal investments in charging stations and tax credits for electric cars. But as Biden’s Day One executive order on climate and the environment recognized, an even greater priority is making gasoline vehicles more fuel-efficient. My research focuses on energy problems, including transportation and climate change. I believe though EVs are impor...

The road to electric vehicles with lower sticker prices than gas cars – battery costs explained

Electric vehicle sales have grown exponentially in recent years, accompanied by dropping prices. However, adoption of EVs remains limited by their higher sticker price relative to comparable gas vehicles, even though overall cost of ownership for EVs is lower. EVs and internal combustion engine vehicles are likely to reach sticker price parity sometime in the next decade. The timing hinges on one crucial factor: battery cost. An EV’s battery pack accounts for about a quarter of total vehicle cost, making it the most important factor in the sales price. Battery pack prices have been falling fast. A typical EV battery pack stores 10-100 kilowatt hours (kWh) of electricity. For example, the Mitsubishi i-MIEV has a battery capacity of 16 kWh and a range of 62 miles, and the Tesla model S has...
