A torch by the bed for nightime visits to the throne room.

Don't buy ready meals

More modern ideas
Use a slow cooker , it can bake and roast too. Plenty of yt vids if you are not sure.
make and use a hay box, do it now, don't wait for emergencies. You need to learn cooking times.
Whoops! Electric just gone out, having an amazing thunderstorm right overhead!
Clothes don't need washing after just one use. Air and refresh on a hanger and wear again a day or so later. You can rotate several things this way. Only wash when actualy dirty . ie once a week.(I see shock and horror at that idea!)
Wear a vest when it's cold, yes, kids too. I know it's not cool for teens and they would rather freeze looking cool, but they will get over it. You will not scar them for life, and may even thank you once they grow up!
Learn to knit or sew...boys too!
If boys get funny about sewing, show them Simon in the woods yt vid on sewing a zip in a hammock,
make a bushcraft shirt out of a wool blanket offcut or, as I did for a youngster out of a charity shop wool skirt, as long as its not pink!(unless it's a girl)
Bubble wrap windows that are draughty or single glazed, particularly in low heat rooms like bathrooms and toilets.
Rugs on the floor add extra insulation underfoot.
Line your curtains with cheap fleece blankets or even adding another layer made from an old duvet will add warmth.
Go to bed early with a hot drink, hot water bottle, cosy socks and read.
An old hoodie makes a good bed jacket while reading.
Charity shop for books, build a blackout library for nights with no TV or computer.
