My parents recently moved and are going through throwing out and replacing a lot of their furniture. They have 3 large old fashioned crt televisions that are quite heavy, and I'm considering encouraging them to replace those on the grounds that they are not just heavy and don't fit in the new house, but are also highly energy inefficient. The newest of the tvs is at least a decade old, the oldest likely more than two decades old.
I have two questions in regards to replacing them, closely related.
If I convince my parents to replace them, will the environmental savings in terms of less energy consumed be enough to justify the harm of manufacturing new televisions? It seems even good will won't take crt televisions nowadays, so the old tv will be disposed of entirely if replaced.
Can anyone point me to a good analysis of the financial savings in energy of a new flat screen compared to an old television, since I would have to justify replacing them by convincing my parents that they will save more.
