> The amount of electricity is not proportional to the market cap. It's proportional to the difficulty. But the difficulty is proportional to the amount of miners, which is proportional to the profitability of mining, which is proportional to the price, which the market cap is proportional to (i.e. price x supply). So electricity is indirectly proportional to the market cap. > One solutions is to increase the block size, another is to use a secondary chain. Those solutions don't address the energy spent on mining, they just allow more people to transact. The former means more transactions (more fees), the latter means fewer but more expensive on-chain transactions (more fees). Either way I believe the block reward (and thus the amount of energy miners will throw at getting that reward) will be roughly the same, it'll be a function of how much people value and want to use bitcoin.
