Setting aside the fact that things like BBC have nothing to do with energy taxes...
Let's say there are X things government currently funds thanks to energy taxes, and overnight everybody stops paying for energy - do you think government's wouldn't just increase other taxes if they needed to make up for lost revenue?
These seem like completely different problems, and your wishing you paid less taxes doesn't mean the world can't move to better energy systems.
Lobbying by companies who make money under the current system and who aren't best places to react to developments is the biggest roadblock, not government fearing the loss of energy taxes.
But energy bill from central government is bundled with many taxes (like 50%). For example:
- CO2 emission tax
- BBC license (or local equivalent), like paying CNN every year...
- subsidy tax for oil energy complex
- loyalty tax for pensioners
- subsidy tax for current war policy....
