Lithium battery costs have fallen by 98% in three decades
The thought exercise I most would like the answer to is: how much of this (that is batteries and solar/wind) could have been advanced in the 50s and 60s if the petrol companies weren't, uh, redirecting investment. Was the transistor or imaging or key materials engineering needed to enable modern batteries and solar five decades earlier, or was there just a lack of real funding?
