Questions

Questions (11)
Question
The term energy has various meanings and definitions, related to the idea of a capacity to act, emerge, transform or set in motion. In physics, energy is defined as the ability to do work. In technology and economics, "energy" refers to a natural resource. Will the current and complex global energy scenario, as a result of the confrontation between Russia and Ukraine, provide any kind of advantages for the development and implementation of more ecological and sustainable energy alternatives? I greatly appreciate your time and attention.
Question
On a global scale, the energy sector is acquiring great dynamism as a result of the notable technological changes that have been taking place in recent decades. This has been motivated by the significant reduction in the cost of renewable energies, such as solar photovoltaic and wind power, and the growing concern caused by climate change, caused by the increase in the concentration of carbon dioxide generated, mainly, by massive use of fossil fuels. In this context and considering aspects such as Distributed Generation, Transactive Energy: What would be possible applications of blockchain technology in the field of energy?
I appreciate your participation in this discussion.
