A carbon offset is a certificate representing the reduction of one metric ton of carbon dioxide or its equivalent in other greenhouse gases. Carbon offsets are traded in voluntary and compliance markets. They are used to offset greenhouse gas emissions from activities such as travel, manufacturing, and electricity generation. Carbon offsets are a way to … Read more
A smart grid is an electricity delivery system that uses digital technology to detect, respond to, and manage fluctuations in electricity demand. The goal of a smart grid is to make the electricity system more efficient, reliable, and secure. Smart grids use a variety of digital technologies to detect and respond to changes in electricity … Read more
The term “ohm” is used to describe the unit of electrical resistance. The ohm is the SI unit of electrical resistance, named after Georg Simon Ohm. The symbol for the ohm is the Greek letter omega (Ω). What is an ohm equal to? An ohm is a unit of measure for electrical resistance. What is … Read more
CAES is a type of energy storage that uses compressed air to store energy. The air is compressed using either a piston or a turbine, and the stored energy is used to power a turbine that generate electricity. CAES can be used to store energy from renewable sources such as wind and solar, as well … Read more
The term “Faraday” is used to describe the process of converting electrical energy into mechanical energy, or vice versa. This process is named after Michael Faraday, who first discovered it in 1831. Faraday’s law states that when an electrical conductor is placed in a magnetic field, a voltage is induced in the conductor. This voltage … Read more
The International Telecommunication Union (ITU) is an international organization that promotes the standardization and coordination of telecommunication networks and services. It was founded in 1865 as the International Telegraph Union, and its name was changed to the International Telecommunication Union in 1934. The ITU has a membership of 193 countries and over 700 sector members, … Read more
The American Recovery and Reinvestment Act of 2009 (ARRA) is a stimulus package enacted by the 111th U.S. Congress and signed into law by President Barack Obama in February 2009. The total cost of the stimulus package is estimated to be $787 billion, with $288 billion in tax cuts and $499 billion in spending. The … Read more
A capacitor is a device that stores electrical energy in an electric field. It is composed of two conductors (plates) separated by an insulating material (dielectric). The conductors are usually made of metal, and the dielectric can be a variety of materials, including air, paper, ceramic, glass, and plastic. The amount of electrical energy that … Read more
UPS systems are traditionally designed to support a single piece of equipment, meaning that the system is only sized to support the power needs of that one specific device. However, in many cases, it can be more efficient and cost-effective to design a UPS system to support multiple pieces of equipment. This is known as … Read more
Distributed energy resources (DER) are small-scale energy generation or storage devices that are connected to the electric grid. DER can include solar photovoltaic (PV) panels, wind turbines, battery storage systems, and combined heat and power (CHP) systems. DER can provide a number of benefits to the electric grid, including improved grid stability and reliability, reduced … Read more
