 In this episode of The State of Energy, Rand DeWitt and Tom Clark break down the EPA’s proposed rollback of the 2009 greenhouse gas endangerment finding and what it could mean for farmers, truckers, and fleets facing costly DEF systems and looming 2027 emission standards. From skyrocketing truck prices to the surprising truth about “zero emissions,” they explore how propane engines—already meeting future requirements—offer a cleaner, cost-effective alternative. Plus, they share a real-world example from Zion National Park, debate EV range anxiety, and pitch the ultimate clean vehicle concept combining electric torque with propane power.
