Risks to Ukraine’s Nuclear Power Plants Are Small—but Not Zero

“That’s certainly something I think the Russians would make an effort to avoid doing, not only because they don’t want to contaminate the country they’re trying to occupy—but, also, Ukraine needs electricity from those plants,” says Ed Lyman, senior global security scientist at the Union of Concerned Scientists and coauthor of the book Fukushima: The Story of a Nuclear Disaster.

All the Things That Drain Your EV Battery

All the Things That Drain Your EV Battery

Heating and cooling power consumption could range from a few hundred watts when the ambient temperature is close to optimal, 1-2 kW when the environment is very hot or cold, or even up to 5+ kW if the vehicle is starting off very cold and the battery needs to be warmed up by a resistive heater.”.
