Let me first provide a bit of context. I'm no fan of fossil fuels or being dependent on them. Even IF they are not messing up the atmosphere as some are apt to claim, they are not a renewable resource and sooner or later we are going to run out of them , how much later again a point of debate but nobody debates it will happen. To me it make sense to find a way to do something better 'just in case' most the majority of scientist who study climate happen to be correct AND because why be dependent on a limited resource that you might be able to use in other ways if you don't have to.
That being said, all these decisions come with real human costs. One example is that the typical cap and spend strategies many people support may the ability to raise fertilizes prices to a level that will cause mass starvation in impoverished countries ( a lot of fertilizer is from natural gas a process that produces C02).
Other 'green' strategies are bound to fall square on the shoulders of consumers as well, replacing power plants creating new infrastructure , replacing vehicles , all cost money ( and energy ) and resources. The complexity of the problem of breaking global dependence on fossil fuels in a carbon negative way may be one of the greatest challenges to human engineering.
So for those who may be more able then myself:
Where are the conversion kits so that we can convert our exist vehicles to electric ?
Where is the way of fast charging or exchanging batteries so we can repower these vehicles in minutes rather then hours?
Where are the affordable batteries / solar panels/ green power alternative or any other technology that can be paid for by the average builder without raising the prices of homes
out of reach for most people ?
We need these things to be as affordable and functionally equivalent to the technology they replace or we can expect great resistance in widespread adoption.
All of this assumes of coarse it is possible to continue or modern technological lifestyle in a carbon neutral fashion. Does we currently expend more power then we are able to take in from the sun without killing the plants?
