The Trump administration’s efforts to roll back the light-duty vehicle fuel economy standards have received a lot of attention. Much less known is its stalling of heavy-duty vehicle fuel economy standards, which would also boost fuel consumption and greenhouse gas emissions — significantly increasing health risks for all.
Many of today’s cars are already available with connected and autonomous vehicle (CAV) technologies such as adaptive cruise control and automatic emergency braking. Testing of fully autonomous vehicles is underway in cities and states across the United States, including Arizona, Texas, and Wyoming. And 22 US states and Washington, DC, have already passed legislation to shape the rollout and impacts of these vehicles.
The environmental impact of autonomous vehicles (AVs) is up in the air, but Judi Greenwald sees advantages to integrating them into fleets that provide mobility as a service.
Blockchain is generating a lot of buzz as a promising system to verify and track peer-to-peer transactions in the energy sector. It could have multiple applications although there is still debate about which, if any, will work well. What’s clear, however, is that companies are already exploring uses of blockchain to save energy. Let me tell you about three applications that show promise.
The Trump administration appears to be nearing a decision to roll back light-duty fuel economy and greenhouse gas standards. Automakers have promoted this reckless action by claiming that the standards are too tough now that consumers are buying larger vehicles, which typically use more fuel.
As new models with longer ranges, state-of-the-art features, and lower prices enter the market, 2018 is widely expected to be the year of the electric vehicles (EV).
Washington, DC—For those who like clean vehicles with state-of-the-art technology or simply want to reduce their environmental footprint, today’s market has good news. A slew of affordable, efficient, tech-smart cars and trucks are now on the market, giving American consumers plenty of options for buying a greener vehicle. Today at greenercars.org, the American Council for an Energy-Efficient Economy (ACEEE) released its 21st annual GreenerCars vehicle ratings to help consumers make that choice.
With the threat of a rollback looming, two new reports from the Environmental Protection Agency (EPA) show that federal fuel economy and greenhouse gas emissions standards for vehicles are working. Furthermore, new models, such as those on display at the Detroit Auto Show this week, show that additional gains are within reach.
The first-ever Run on Less roadshow demonstrated just how fuel-efficient a tractor-trailer can be in real-world operation. Seven Class 8 Freightliner, International, and Volvo tractor trucks drove 50,000 miles across the country, carrying more than 55,000 lbs. of goods on average, and converged in Atlanta on Sunday for the grand finale.
A key element of the “Phase 2” heavy-duty vehicle fuel efficiency and greenhouse gas emissions standards adopted last fall was the program’s inclusion of trailers for the first time. That addition alone will deliver a cost-effective 7% improvement in tractor-trailer fuel efficiency.
