Lets break down your "mentalism". I'm not going to argue global warming as I'm sure you think its an evil hoax, so lets just do basic science and economics
1) Compulsory replacement of lightbulbs with more expensive technology "for the environment" (no it's not just because there's a huge profit to be made selling new technology at 20x the price, honest it's not). Never mind that LED technology has much more potential.
Lots of parts of the US, California for instance, and parts of Europe (UK) have or will have issues with electricity supply. Light bulbs are quite a part of that consumption this makes electricity a scare resource (excluding its environmental impact) by having things like energy standards against TVs, cookers and indeed lightbulbs you ensure that this scarce resource isn't wasted. So yes LED technology might be better but the point is that the old technology was certainly worse. Thus by making people use energy efficient devices (including lightbulbs) you actually stop things like rolling brown outs etc.
2) Creation of flimsy plastic bags that fucking fall apart so that you need twice as many to carry the same groceries followed by the removal of plastic bags with studier but still flawed and breakable "green" "enviro" bags which are now sold at large profit instead of being given away. Lets nickel and dime our customers to death in the name of the environment - but we couldn't possibly stop filling their mailboxes with dead tree junk mail. Fucking hypocrites!
Now again putting away the dead dolphins and concentrating on the costs of landfill and the belief that you don't want to live in a socialist country this switch again makes sense. What you are given a choice between is a poor product for free (socialism) or paying a market price for something that lasts longer and has more value (capitalism). So its not enviromental nutters its just plain old capitalism at work.
3) Solar hot water systems that cost more environmentally and financially to produce, install, run maintain than their conventional counterparts, often require that they be supplemented/boosted by a conventional heater (so net negative gain in terms of production). Honest it's not about selling shit people don't need!
Now the Solar hot water systems I know about (for instance the ones that I've seen down here in Australia) are definately nothing like this and are for large parts of the year totally self sustaining. Some of them are pretty damn technically simple (black pipes on the roof) with very little cost of production. If you aren't forced to use these however what is your problem? Its capitalism at work again, the latest Ferrari is a ruddy expensive car, has rubbish amounts of space and sits only two people, why on earth would people pay over the odds when they could just get a truck? The majority of solar water systems sold in the right markets (i.e. hot countries) and geothermal systems in the right countries (e.g. Iceland) are much cheaper to run than conventional systems, sure some people put the system in the wrong place (e.g. a solar system in Ireland) but those things happen all the time. Still I could generously give you that some environmental people are a bit silly (David Cameron and his windmill springs to mind).
4) Water conservation and rationing. What a fucking joke. It's got nothing to do with environmental impact of building more dams and desalination plants and everything to do with the dollars it takes to do so. Water is not scarce on this planet. It recycles well if you don't abuse it badly with extremely noxious chemicals. The system is build to deal with the shit and piss of every creature on the planet. Anything short of sewage and noxious chemicals often can be reused if we weren't so skitish about grey water. Water as a scarce resource, and kids no longer being able to play in their back yards with a hose has nothing to do with environment and everything to do with politicians lining their pockets with taxes that should be spent on infrastructure.
Now here is where you move firmly into a mental category of your own. Australia is a massive problem with water shortages due to a long term drought. In the US the problem is that water hasn't been treated as a scarce resource and has therefore been treated as free money (SOCIALISM) by farmers in particular who have done ridiculous things like rice farming in areas that really don't get the rainfall to justify it. Building more dams and pipes doesn't help if the water is in the wrong place and if people (farmers) keep deliberately wasting water as it has no price attached to it. If water was priced fairly as a market commodity (capitalism) then it would mean that kids would be much more likely to play with the hose in the garden but that they'd have to pay the right market price for that water. With farmers being subsidised by the state (SOCIALISM) to waste water and grow stupid crops water has become an even more scarce resource than it would already be. FRESH water is a scarce resource in many parts of the planet, California is one of those places, Nevada, Arizona, Texas are others, Australia is a country with a water problem and Africa is covered with them. Throwing money at "build another damn" isn't about fixing the problem, the problem is one of consumption and the creation of a socialist agricultural system that relies on government subsidies to grow things people don't want (more corn syrup kids) and to waste water while they do it.
Only one of the things you talk about could arguably be an "enviromentalist" element, the others have very strong economic reasons for attacking the problem in the way that environmentalist people talk about. I'll use another "environmentalist" argument.
Many moons ago some "environmentalists" went to hotels and pointed out that they were using loads of detergent and water to clean towels and sheets that might not need it. Their suggestion was to put little paper cards into the hotel rooms that say "if you don't want the towels washed then hang them up" and "we change the sheets after each guest or every 3 days, if you want it changed more often just let us know". This piece of dreadful environmental insanity saved the hotels lots of money and helped protect the environment.
This is what most smart environmentalists do, hence cap & trade or a carbon tax, hence water pricing. Its about using a capitalist system to create a true market price for a commodity rather than a price which excludes the overall costs. Things like water are today the equivalent of being sold a car and never having to pay for petrol and wondering why you are running out of oil.
