You may not be an expert, but your instincts are correct. "The consensus" is we need to stop driving ICE vehicles to stop global warming, or pollution, or anxiety, or something. Solar, wind and pixie dust will save the day--coal and natural gas are evil--and nuclear power is off the table, based on a different "consensus".
As you implied, solar energy is so diffuse that it will never provide even 20% of the electricity we need, particularly if 100 million EVs need charging--can you say blackout? Someone will screech "But my house has solar panels and we produce 100% of our power!" If it's true (probably not), the screecher lives in Arizona and he spent $60,000 for panels and batteries for $4000 worth of electricity per year. After 20 years his system is worn out and he spent all that money up front (actual cost $108,000 over 20 years). Dumb. Centralized generation is efficient. Individual systems are primarily toys for those with energy guilt or money to burn. Wind power is even less effective--might produce 20% of our needs with 10 million wind turbines. And they look so nice covering the horizon.
Transitioning to EVs will accomplish exactly zero--except diverting money and natural resources away from other pursuits.
The people who claim "consensus" are environmentalists, not engineers. The environmentalists told the politicians, and off we went. Meanwhile, the engineers are shaking their heads, saying "No No NO!".
Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus. There is no such thing as consensus science. If it’s consensus, it isn’t science. If it’s science, it isn’t consensus. Period.--Michael Crichton
