Use Blackout Curtains to Cut Your Power Bill

Whether it’s the cold of winter or the heat of summer, your windows are a major energy leak for your home. Having double paned windows can help quite a bit, but good quality blackout curtains can help you save energy as well.

Quality matters with blackout curtains. If you check the reviews on Amazon, you can see that some curtains are far better than others at blocking light. There’s not much point in putting up blackout curtains if they don’t do the job well.

Cost of Blackout Curtains

Blackout curtains have a wide range of prices, depending on brand and size. Pick yours based on reviews showing that they do a good job and by how you want your windows to look. They don’t have to be unattractive.

You can also make your own for a reasonable cost, and it doesn’t have to be complex. Dark colored fleece can do pretty well, for example. The main thing you want to look for is a material that will block a lot of light. It doesn’t necessarily have to be a dark color, so long as it doesn’t let much light through. Layering the fabric can work as well. If you don’t sew, fabric glue may also work, although I don’t trust it to be as strong.

If you don’t want to spend money on all your windows, just get blackout curtains for the ones that gain or lose the most heat. You can pull the curtains back on warmer winter days to let sunlight in, and close the curtains when the day cools down to keep the heat in.


If you don’t want to put up curtains, there are other ways to block heat in your home. I use flattened cardboard boxes in some of my windows. We have a number of them from when we moved a few years ago. We’re a little discreet about where these go, as we have a picky homeowner’s association to deal with and I don’t want to hear anything from them.

You can also use Mylar in your windows. You can buy some that is designed for use in windows, but you can also get it in the form of emergency blankets such as you might keep in an emergency kit, and cut that to size. It blocks quite a bit of energy, yet it’s thin enough you can open the window over it. That’s nice if you’re happy with your window coverings aside from how they keep the heat in or out.

    I never thought about curtains as energy savers. I always simply wear a warm sweater, but this is a good alternative. Thanks!
