Blockchain can enable customers to directly transact excess power with other consumers within a specific region, leading to the development of startups and utilities exploring this concept.
The second application involves using blockchain to create cryptocurrencies for financial transactions within the energy sector. Some utilities have already initiated pilot projects to facilitate such transactions. Additionally, blockchain could bring further changes to the energy ecosystem, such as introducing multiple rates within markets instead of a single utility-determined rate.
The Current State of the Energy Sector
Challenges
Lack of Transparency
The energy sector, especially in its traditional forms, has been criticized for its lack of transparency. This lack of transparency manifests in various ways, including unclear pricing mechanisms, hidden fees, and the opaque nature of energy sourcing. This opacity makes it difficult for consumers and regulatory bodies to trace the origin and cost of energy, leading to a lack of trust and hindering the adoption of innovative energy solutions.
Centralization Issues
Centralization in the energy sector refers to the concentration of production and distribution control in the hands of a few entities, often large corporations or government bodies. Centralization can result in monopolistic practices, limiting consumer choices and stifling competition. Additionally, centralized energy grids are vulnerable to single points of failure, which can cause widespread disruptions in case of malfunctions or targeted attacks. The centralized model also tends to neglect remote or less densely populated areas due to economic viability concerns for extending the grid.
Efficiency Concerns
Efficiency in the energy sector involves optimizing the use of resources for energy production, distribution, and consumption. Traditional energy systems often experience significant losses during production and transmission over long distances. Moreover, the mismatch between energy production and demand can lead to wastage.
