i think 2020 is too far to say any thing about that. but the power of the bitcoin can be realize from today. the present condition of the bitcoins shows its position clearly.

If the bitcoin price just double from the current price, it will use similar amount of energy as now. So no worries.

TRUE: If the price were to just about double about every four years then the Bitcoin Network would continue to consume about as much energy as it consumes today. But, if the price more than doubles over each era then it will consume more than it does today.

2020 is pretty far from now.

I'm sure someday the devs will come up with something to solve the potential problem.

Since power consumption is fundamental to the design of Bitcoin it would take a fundamental change (like PoS or PoS/PoW hybrid as suggested) to change this. I personally do not believe that a change this fundamental would ever be accepted by the majority of miners and nodes. We will see.

The bitcoin's energy problem is less than the Etheruem. If the Ethereum continue to rise in price, its power consumption will be a lot as it does not have the block halving mechanism. But it will be PoS in the future.
