Both Pressure cookers and crock pots are energy efficient.@vehve
For what its worth a crock pot uses less energy than the stove... even just a simple one has high medium and low and warm settings.
Depending on recipe food is cooked long and low and they are great for making just about anything you can roast in the oven. I have even done a turkey in a large crock pot.
So far I have had poor success with beans and chili though. But i have successfully made Chicken, Roasts, Apple butter, and soups in the crock pot.
You season less because the seasoning goes further.... You still sear beef or pork off before cooking in the crock pot with moist heat.
I have taken a solidly frozen chicken and put it in the crock pot with just a splash of water.... I season it with salt pepper and garlic and put in a bay leaf..... Startt it in in the AM like six am and come home from work to a pull off the bone done chicken..... I pull it out remove the bones and serve it like a chicken stew.

I use my pressure cooker a couple of times a week. I made beans with hamburger chili in mien on the First.
Yum!
