Oil is disposable, solar panels are not. If you have solar, and then piss off the CCP to the point where they attempt to stop you from acquiring more of it, you don't lose the solar you already have. Those solar panels will continue generating energy for years, if not decades, afterwards.

It's also important to note that the US also produces oil[0]. There are some quirks of the market and refineries that make it difficult to consume our own oil, but we could potentially build more domestic processing. The real problem is that pesky global market that puts costs on the state's ambitions for power. To put it bluntly, American oil is expensive. We can survive an oil crisis iff we are willing to pay astronomical prices at the pump; but if we are doing this assuming we can just enjoy cheap gas while the world burns, we are going to get a rude awakening.

Think about it this way: buying your energy in the form of oil is like exclusively using streaming services for your entertainment needs. It's cheap, easy, convenient - until the plug gets pulled and it suddenly stops being those things. Buying solar is like buying physical media - you have to pay up front and it's more of a hassle to get started, but it can't be turned off on a whim.
