Everybody wants clean, green energy. But nobody wants a power line in his or her backyard. We hear a lot about the imminent electric car, but what happens to the energy grid when thousands of consumers add a car-charger to the heavy load already required for air conditioners, clothes dryers and other appliances? And where will emerging economic superpowers like China and India get their power? Why do we seem to lurch from one energy crisis to the next?
The four-hour miniseries “Powering the Future” (7 p.m. and 8 p.m., Saturday and Sunday, Discovery) takes a hard look at the energy choices that confront us and the problems that can, or rather will, arrive in the near future, if we fail to act.
• Jonathan Silverman (“Weekend at Bernie’s”) stars in the title role of the TV comedy “Jack’s Family Adventure” (8 p.m., Saturday, Hallmark) as a stressed advertising executive who discovers that for all of his gadgets and skills, he has forgotten how to communicate with his family.
Our city-slicker exec takes off for the mountains with his wife (DeDee Pfeiffer,“Cybill”) and teenagers and, away from the city, they unpack, unplug and unwind and learn some essential wisdom from a cowboy (Peter Strauss) named Cohen.
• “Pit Boss” (9 p.m., Saturday, Animal Planet) returns. Don’t let the title confuse you. It’s not set on a NASCAR racetrack or a barbecue joint. The “Boss” is actor and entertainment executive Shorty Rossi, known for his diminutive size and outgoing personality. When not running an entertainment agency — Shortywood Productions — that secures acting jobs for little people, he’s rescuing pit bulls from abusive owners, backyard breeders and dog-fighting rings.
• Bridesmaids have long chafed at their plight. Forced to buy expensive and often ugly gowns and reduced to playing a mute chorus to the bride’s Diva, they have ample grounds for complaint.
“Revenge of the Bridesmaids” (7 p.m., Sunday, ABC Family) takes the hurt feelings a few steps beyond believability and has some fun along the way.
Best pals Abigail (Raven-Symone) and Parker (JoAnna Garcia) return to their small Southern town to discover that their friend Rachel (Chryssie Whitehead), has lost her one true love Tony (Lyle Brocato) to their scheming ex-friend Caitlyn (Virginia Williams). So they decide to insinuate themselves into Caitlyn’s wedding party to sabotage the proceedings and set the course of true love straight.
This requires a lot of gullibility on Caitlyn’s part. After all, if she were crafty enough to hornswoggle Tony, you’d think she’d see through their ruse. Her icy Southern Belle mother Olivia (Beth Broderick) is not so naive, and the scenes between her and the two upstarts provide the film’s best moments. She’s not above using body image as a weapon and reminds Abigail of how the cruel kids used to call her “Flabigail.” After those fighting words, all bets are off.
