Rapid Green Energy Transition Will Likely Result in Trillions of Net Savings
Garbage comment from an uninformed SW engineer: How, in the current economic and geopolitical environment, can they project that production costs will continue to decline?<p>Green tech requires massive amounts of dirty energy to produce.  It also has been benefiting from globalization which is now going in reverse.  I would add at least 5 years to any timeline given because of the recalibrating global energy and materials supply chains will be undergoing over time.<p>We&#x27;re probably short of copper.  Is anyone figuring out a way to use aluminum as a substitute in many applications?  We can work around several of the other critical shortages(nickel, cobalt, not-so-rare rare earths, lithium) in time, either with alternatives or increased extraction, but copper seems like a tough one.<p>There is a lot of wishful thinking or naivete in the political class driving these transitions.  I agree that we need to move rapidly to decarbonize but there seems to be a lack of appreciation for the actual work involved in the transition.  There is also a parasite-class of folks whispering deceitful tales in the ears of politicians(ahem, hydrogen, ahem) which really only cares about getting their cut.<p>Politicians need to understand you don&#x27;t just order solar panels and batteries off Amazon.  Someone needs to make them, and that someone better be a country you&#x27;re not in a proxy war or a hot war with.  We need to invest in practical measures not just fairy tales that leave us in the dark for a decade or more while we figure out hard lessons.
