I think the majority of people would easily buy the 1000 watt console, so don't think that everyone is so environmentally conscious... it's just the opposite. The reason is prosaic, it was expensive until now. But if they bring it at an affordable price, many people would buy it.As performance improvements from node changes become smaller performance will scale with power or things like ai, or more efficient upscale. PC will always have a power advantage. No one wants a 1000W console.
However, it is more likely that from now on manufacturers will produce hardware that consumes less and less power instead of performance. Marketing can also be built on this.
