I like that people develop and use highly efficient equipment. These are better for the environment and companies because they can do the job using fewer resources, like electricity, gas, and water.
Maybe every person will aspire to use equipment like these at home, too. They can save a lot of money through this. Some of them changed the energy supplier, but I don't know if this is enough. I know that there are some websites where you can compare the tariffs, like
Simply Switch, but if you are using your old TV or air conditioner, you won't save much money.
