The heat pump water heater is the silver bullet to these water heating problems. It’s efficient, saves money, reduces or eliminates air pollution, and it delivers hot water with faster first hour ratings than electric […]

Are Fat-Tire E-Bikes Too Fat?

Jennifer Sensiba — Wed, 24 May 2023 19:35:44 +0000

Over the last three years, I’ve done a lot of e-bike reviews. While some of them have been really cool townie and street bikes, most of them have followed a very popular formula: a mountain bike with front suspension, loads of battery capacity, and 4″ tires. But, not long ago, Snapcycle sent me something a […]

BorgWarner Helps School District Charge Multiple Buses With One Charger

Jennifer Sensiba — Sun, 30 Apr 2023 21:38:05 +0000

Charging medium- and heavy-duty electric vehicles (EVs) is more expensive than charging light-duty EVs due to several factors. First, medium- and heavy-duty EVs have larger battery sizes, which require more energy (measured in kilowatt-hours) to charge fully, resulting in higher electricity consumption and costs. These vehicles require high-power charging infrastructure that can provide all of […]
