How long did it take to transition to an oil-based economy? Decades? The car was invented in 1886; a majority in the USA didn't own a car until around 1927, some 41 years later. Renewables are only just reaching the breakthrough point, price-wise, where they are highly competitive with other forms of energy generation. If the rate of adaptation is the same as for cars, the majority of households with be using renewables by 2060. I suspect though the adaptation rate will be much faster, because economically it will make much more sense. LED lights certainly do now, as a replacement for the short-lived light bulb. Renewable energy sources have not reached their maximum cost efficiency yet, and may not for years. Eventually they will simply be the best option, while petroleum products will mostly be used for other purposes.
The so called "renewables" need nonrenewable to survive, so how are they renewables. Ethanol comes from corn and corn needs land. Read somewhere that the western US needs to be converted to farmland if it were to generate enough biofuels. Storage needs rare minerals that can only come from the earth. Every day we are reminded that there is only so much oil in the world but never say the same thing about lithium.
Never fear, there is new battery tech coming soon.
"Fluoride-ion batteries offer a promising new battery chemistry with up to ten times more energy density than currently available Lithium batteries. Unlike Li-ion batteries, FIBs do not pose a safety risk due to overheating, and obtaining the source materials for FIBs creates considerably less environmental impact than the extraction process for lithium and cobalt."
