Energy market management is another historically highly centralized sector.


In the United States, for energy transactions, one has to go through a trust company like Duke Energy, the same happens with National Grid in the United Kingdom.


Alternatively, companies and individuals will have to deal with a retailer, who purchases energy from a large utility and sells it to individual users.


Startups like New Yorker Transactive Grid offers a grid energy service based on the opensource Ethereum platform, which allows customers to carry out transactions on decentralized energy generation systems (such as individual condominiums of the Big Apple) effectively, thus enabling individual inhabitants to generate, buy and sell electricity independently by exchanging it with the neighbors.
