Understanding how non-profit entities manage electric grids to ensure supply-demand balance

Independent System Operators in smaller areas and Regional Transmission Organizations that operate across multiple states run wholesale electricity markets. Electricity suppliers can submit competitive bids to meet estimated demand in day-ahead markets while keeping consumer costs low. ISOs and RCOs also inform markets of deviations in these estimates so that suppliers can adjust how much power they generate, which is then bought and sold in real time.

Distinguishing between Web 1.0, 2.0, and 3, all made possible by the internet

The World Wide Web began as read-only, static webpages on Web 1.0, where data could not be entered. With Web 2.0, the online interface became a read-write space for data entry, post creation, and forum participation, among other activities. Web3 is intended to be decentralized, user-owned, and built on blockchain technology.
