While the end goal of fulfilling our energy needs with non-fossil fuels is a widely accepted goal, the plan to get there is one with many opinions.   Amongst the plans, there are two I'd like to call out as I consider them at the top of the heap.

The first comes from the Andlinger Center for Energy and the Environment (ACEE) at Princeton University.  As per its website, ACEE "is a multidisciplinary research and education center, whose singular mission is to develop technologies and solutions to secure our energy and environmental future."  One of its many deliverables is "Net Zero America" released in February of 2021.  As per the Net Zero America website, the report "quantifies five distinct technological pathways, all using technologies known today, by which the United States could decarbonize its entire economy."

The second comes from the International Energy Agency (IEA).  As it states as its mission, "the IEA works with governments and industry to shape a secure and sustainable energy future for all."  From its start in 1974, the IEA hosts an extraordinary amount of data on energy.  All kinds of data.  For example, data on supply.  Data on consumption.  Data on prices. Data, data, data.  And from the data, it also produces analysis reports.  One of those reports, released in May of 2021, is "Net Zero by 2050".  As noted on the report's website, the report "is the world’s first comprehensive study of how to transition to a net zero energy system by 2050 while ensuring stable and affordable energy supplies, providing universal energy access, and enabling robust economic growth."

While the ACEE report focuses on the US, the IEA report looks at the situation from a global perspective.

I invite you to at least look over these reports.  I find them to be foundational reference material.
