Glossary
Decarbonizationy
**Decarbonizationy** refers to the comprehensive processes, strategies, and technologies employed to reduce and eventually eliminate carbon dioxide (CO₂) and other greenhouse gas emissions from various sectors, including energy, transportation, industry, and agriculture. This concept involves a...
Decentralized Energy Systems
**Decentralized Energy Systems** refer to the generation and distribution of energy produced closer to the point of use, rather than at a central power plant. These systems involve small-scale energy generation technologies such as solar panels, wind turbines, microgrids, and combined heat and...
Deep Decarbonization
**Deep Decarbonization** refers to the comprehensive and strategic reduction of carbon dioxide (CO₂) emissions across all sectors of the economy to mitigate climate change and achieve a sustainable, low-carbon future. This concept involves not just incremental improvements, but transformative...
Deforestation
**Deforestation** refers to the large-scale removal of forests, leading to the permanent loss of biodiversity, habitat, and ecosystem services. This destructive process occurs when trees are cut down or burned to clear land for agricultural activities, urban development, logging, or other...
Direct Drive Wind Turbine
A **Direct Drive Wind Turbine** is an advanced type of wind energy system that forgoes the traditional gearbox mechanism to generate electricity. Unlike conventional wind turbines that rely on a series of mechanical gears to convert the rotational speed of the rotor into electrical power, direct...
Dish Stirling System
A **Dish Stirling System** is a type of solar energy technology that combines a parabolic dish and a Stirling engine to convert sunlight into electrical power. The system operates by using a large, reflective parabolic dish to concentrate sunlight onto a central receiver. This receiver is part of...
Distributed Energy Resources (DER)
**Distributed Energy Resources (DER)** refer to small-scale electricity generation or storage technologies that are located close to where the electricity will be used, rather than at a large, centralized power plant. These resources can include solar panels, wind turbines, combined heat and...
Distributed Wind Energy
**Distributed Wind Energy** refers to the generation of wind power on a localized scale to meet the energy needs of communities, businesses, farms, or individual properties. Unlike large-scale wind farms that feed electricity directly into the grid, distributed wind systems are often positioned...
Downwelling Radiation
**Downwelling Radiation** refers to the stream of electromagnetic radiation that travels downward towards the Earth's surface from the sky, encompassing both solar and atmospheric sources. This phenomenon is a critical component in the Earth's energy balance and climate system. In essence, it...
Dynamic Energy Pricing
**Dynamic Energy Pricing** refers to a flexible rate structure where the cost of electricity varies in real-time or at different intervals throughout the day. Unlike traditional fixed-rate pricing, this system aligns energy prices with demand and supply fluctuations, promoting more efficient...
