Power Ledger is proof that blockchain technology is increasingly present in our lives. Its project aims to provide people with the possibility to negotiate directly with their solar or renewable energy sources without intermediaries. This really makes it easier, because without intermediaries the advantages are much better for those who negotiate and even for those who buy. A project that really has a role in our lives, and combines blockchain technology with sustainability. Through its software users can negotiate in the best possible way all their solar energy produced in surplus. Their entire system is powered by the ethereum platform, and they have their own root token POWR, which is already being traded on several exchanges and has a good rating in the crypto market. I really see the future for projects like the Power Ledger, because the world needs to evolve and if it can do it in a reliable and clean way it is a big step forward, and Power Ledger has exactly that purpose.
