The internet and electricity are two of the most important innovations in human history. Electricity is a set of physical phenomena associated with the presence and motion of matter possessing an electric charge. It is generated by spinning a magnet inside a coil of copper wire, creating an electrical current. This process was discovered by English scientist Michael Faraday in 1821. The internet, on the other hand, is a global network of interconnected computer networks and electronic devices that communicate with each other using established protocols. It has revolutionized communication, commerce, and culture, allowing instant communication and the exchange of vast amounts of information. Together, electricity and the internet have transformed our world, powering our homes, devices, and digital connections.

What You'll Learn
Broadband over power lines (BPL)
BPL works by superimposing a high-frequency signal carrying broadband data on the lower-frequency alternating current that delivers standard electric power. To use BPL, power outlets must be slightly modified with an extra computer socket. Users then plug a special BPL modem into the modified outlet and connect it to their computer to access the Internet. This setup enables data transmission between all electrical plugs in a house, allowing for the networking of various appliances.
BPL has been tested in several cities in the United States and the United Kingdom, and it is also known as "Ethernet over power" or "HomePlug" (named after the alliance of manufacturers who make the equipment). It is also referred to as "networking over the mains" in the UK.
One advantage of BPL is its ability to provide Internet access to areas where fiber optics or other broadband infrastructure may not be available. Power companies that supply electricity can leverage their existing power lines to provide inexpensive broadband to their customers, helping to reduce broadband costs overall. BPL also offers compatibility with Wi-Fi and enhances the range and reliability of existing wired and wireless networks.
However, despite its potential benefits, BPL has not gained widespread adoption in some countries, including the United States, the United Kingdom, and Australia.

Internet of Energy (IoE)
The Internet of Energy (IoE) is a system that incorporates the Internet of Things (IoT) to connect every point within the power grid, from generation and load to distribution, storage, and smart meters. It is a corner of the cyber universe dedicated to all things energy-related.
The IoE is a smart energy infrastructure system that uses IoT devices, such as smart sensors and communication technologies, to manage energy generation and resources. It allows for a multi-directional flow of information, enabling grid operators, energy producers, and distribution utilities to exchange energy information, or big data. This provides these parties with real-time energy consumption trends, allowing them to forecast where and when energy demand or consumption will peak.
The IoE includes energy infrastructure in energy production and delivery by using artificial intelligence (AI) at power plants and power delivery systems. It also automates and upgrades appliances and metering at the point of delivery, or our homes. Smart meters and intelligent appliances or devices help optimize our energy supply, management, and use.
The IoE has numerous applications. It helps countries manage their energy demand, allowing power stations to produce more electricity at peak times and less when consumption is low. This can prevent power blackouts. It also helps grid operators manage the grid in real time, allowing them to diagnose which lines need to be de-energized and reroute power along different power lines in the event of a catastrophic event that disrupts power networks.

Internet of Electricity (IoE)
The Internet of Electricity (IoE) is a concept that aims to modernize the power grid system by leveraging digital technologies and real-time data exchange. At its core, the IoE seeks to address the challenges posed by the variable nature of renewable energy sources, such as solar and wind power, which are intermittent and cannot be controlled.
The traditional power grid has long been reliant on outdated practices, such as customers calling utility companies to report power outages. However, the rapid growth of renewables, including rooftop solar panels and large-scale wind farms, has disrupted the energy mix. This shift towards renewables has also introduced new complexities, with smart meters, appliances, electric vehicles, and charging stations adding stress to the grid.
The IoE proposes a solution by digitizing key transmission nodes, such as substations, and enabling them to exchange information with each other and the broader electrical network. This transformation turns the power grid into a dynamic and responsive nervous system for energy management. With smart substations, utilities can gain real-time control over the grid, eliminating the need for customers to report power outages. Instead, utilities will proactively provide information to customers about power disruptions and restoration times.
The Orbit device, developed by GE Grid Solutions, is a key enabler of the IoE. Orbit utilizes radio, LTE, or Wi-Fi to collect critical data from sensors located in substations, monitoring parameters like transformer oil quality to prevent fires and explosions. Additionally, Orbit ensures seamless communication by automatically transitioning to alternative modes, such as from LTE to radio, during network disruptions caused by storms or other events.
The Energy Internet, as a broader concept, envisions an energy-sharing network with plug-and-play functionality and real-time bidirectional flow of energy, information, and money. This network would integrate small-scale renewable energy systems, electric loads, storage devices, and electric vehicles, facilitating efficient power transactions through technologies like the Internet of Things, vehicle-to-grid, and blockchain. While there is currently no large-scale implementation of the Energy Internet, its potential impact on the future of electricity systems is significant, driving further research and innovation.

Electric vehicles
The first mass-produced electric vehicles appeared in America in the early 1900s, with the Studebaker Automobile Company introducing electric vehicles in 1902. However, the popularity of electric cars declined with the advent of cheap assembly line cars, such as the Ford Model T, and the limitations of storage batteries at the time. Electric vehicles remained in use for specialist roles, such as platform trucks, ambulances, and urban delivery vehicles.
In the late 20th and early 21st centuries, a renewed interest in electric vehicles emerged due to the environmental impact of petroleum-based transportation and the fear of peak oil. Recent advancements in battery technology and charging infrastructure have made electric vehicles a more viable option for consumers. Electric vehicles have several advantages over internal combustion engine vehicles, including superior energy efficiency, reduced waste heat, quieter operation, and no exhaust emissions, resulting in a lower carbon footprint.
The electricity used in electric vehicles can be generated from various sources, including fossil fuels, nuclear power, and renewables such as solar and wind power. In 2023, 14 million plug-in electric cars were sold worldwide, accounting for 18% of new car sales. Many countries have established government incentives, tax credits, and subsidies to promote the adoption of electric vehicles, and several countries have legislated to phase out the sale of fossil fuel cars. As a result, electric vehicles are expected to account for over one-fifth of global car sales in 2024, with China currently having the largest stock of electric vehicles in the world.
