Yea, many companies are researching how to use less electricity to check "one hash" and have made great strides over the years.

The fact that Bitcoin uses proof of work ("POW") means that finding blocks will be electric intensive, and over time the value of the electricity consumed by the miners will approach the value of the total block reward of the blocks.

If the POW were to be changed to proof of stake (users who hold Bitcoin find blocks), or to proof of something else, then electric consumption may decline.
