Substations are essential components of the electrical power system. They serve as the connection points between the high-voltage transmission lines and the lower-voltage distribution networks that deliver electricity to homes and businesses. At a substation, electricity is transformed from high voltage to a lower voltage, making it safe for use. This process is crucial because…

An electrical busbar is a metallic strip, bar, rod, or tube, typically made of highly conductive materials like copper or aluminum, that functions as a central junction point for distributing electrical power. Serving as a high-capacity conductor, it collects electrical current from incoming circuits (like transformers or generators) and efficiently distributes it to multiple outgoing…

Electrical switches are categorized in various ways, often based on their construction, actuation method, and function within a circuit. A common classification uses the Pole and Throw configuration: the Single Pole, Single Throw (SPST) is the simplest ON/OFF switch, controlling one circuit from one location, like a standard light switch. The Single Pole, Double Throw…

System design in electrical engineering involves planning and structuring power systems to ensure efficient, reliable, and safe distribution of electrical power. Switching devices, such as switches and circuit breakers, are integral components that control the flow of electricity within these systems. Circuit breakers are specialized safety devices designed to automatically disconnect electrical circuits during overloads…

Power distribution is the final stage of the power grid responsible for receiving bulk electric energy from the transmission system and delivering it safely, reliably, affordably, and at appropriate voltage and power quality to virtually every end-use customer—residential, commercial, and light industrial—across cities, suburbs, and rural areas. It begins at the distribution substation, where incoming…

A battery is an electrochemical device that converts stored chemical energy directly into electrical energy (Direct Current or DC). It is composed of one or more electrochemical cells, each containing two electrodes—a positive cathode and a negative anode—which are separated by a conductive medium called an electrolyte. When an external circuit is connected, a chemical…

Basic electrical properties describe how different materials respond to electric current and electric fields. The most fundamental of these is electrical conductivity, which measures how easily a material allows electric current to flow through it. Materials with high conductivity (like copper or silver) are called conductors; those with very low conductivity (like glass or rubber)…

An atom is the fundamental unit of matter and the smallest constituent of a chemical element that retains all the chemical properties of that element. It represents the building block of all physical substances in the universe, from the simplest gases to the most complex biological organisms, and its structure dictates how elements interact, bond,…

TeraWulf has entered into two 10-year high-performance computing (HPC) colocation agreements with Fluidstack to deliver over 200 MW of critical IT load at its Lake Mariner campus in Western New York. Contracted revenue for the first ten years is approximately US$3.7 billion, with lease extension options that could raise the total to about US$8.7 billion.…

On February 12, 2025, scientists from CEA-IRFM successfully sustained a hydrogen plasma inside the WEST tokamak in Cadarache, France, for 1,337 seconds—equivalent to 22 minutes and 17 seconds—surpassing China’s EAST tokamak record of 1,066 seconds by approximately 25%. Plasma temperature reached 50 million °C (90 million °F)—roughly three times hotter than the Sun’s core—demonstrating improved heating and stability over…

Per Business Insider Africa on Instagram, Violia has developed a system to convert decommissioned wind turbine blades into usable material for cement manufacturing, offering an environmentally effective reuse strategy. Wind turbine blades—typically made of fiberglass composites—are notoriously difficult to recycle. Violia first shreds them into football-sized chunks before finer grinding and sorting. Violia receives retired…

Google has committed early‑stage capital to support Elementl Power in developing three advanced nuclear energy projects across the U.S., each designed to deliver at least 600 megawatts of continuous power. Google’s investment helps advance site permitting, connection to the grid, and other development milestones. The company gains an option to purchase electricity from the completed…
