in the episode of 40-2... the group is experiencing a lack of energy (low fuel for the vehicles and generators)... why don't they use solar, batteries, and inverters for god sakes?!... even in a zombie scenario, they could harvest solar panels from multiple places throughout california, get the inverters from any walmart/autozone store and get the batteries from all the now defunct cars. This would enable them to run all of their refrigerators, freezers, lights, and small electrical loads. also, they could use propane and natural gas to run gasoline generators too through a modified air intake

I love the show, but this electrical engineer (assuming I survived to this point) would be running circles around Glenn and Datu
