Yea our lives are too convenient and too much filled with useless stuff that no one really needs anyway - and like other comments pointed out the goal is not to replace petroleum 100% immediately - any reduction would already go a long way.
Seeing that we use about 2/3 of the total for transportation fuel it’s not like we need most of it to build the renewable infrastructure - that’s more like a drop in the bucket.
Most petroleum gets used to propel vehicles, to heat buildings, and to produce electricity - and it’s definitely not without alternative there
