Steve Cargil's family has farmed the flat, dry land around Uvalde, a small city in southwest Texas, since 1953.
Cargil, 67, had always assumed that one of his three children would eventually take it over, the way he had from his father.
Cargil and his son, Ryan, had spent months nursing crops of cabbage and onions to harvest. Then a storm rolled through and destroyed them overnight.
By contrast, new coal plants in the US produce power at nearly $90 megawatts per hour, says the Energy Information Administration.
