A
AERODYNAMICS:
The aerodynamic principles governing Vertical-Axis Wind Turbines (VAWT) differ from those of horizontal wind turbines. VAWTs typically rely on drag-based aerodynamics rather than lift-based aerodynamics. The rotor blades of a VAWT generate lift and drag forces, but the drag force is the primary contributor to rotation. This is in contrast to horizontal wind turbines, where lift is the dominant force.
B
BASE LOAD:
This means the minimum amount of electricity needed to meet constant energy demand, often supported by renewable sources such as wind turbines.
C
CLIMATE CHANGE MITIGATION:
One of the most significant challenges we face is climate change, primarily driven by the burning of fossil fuels. Alternative energies, such as solar, wind, hydro, geothermal, and bioenergy, produce fewer greenhouse gas emissions compared to fossil fuels. By transitioning to these cleaner energy sources, we can reduce our carbon footprint and mitigate the impacts of climate change.
D
DECENTRALIZATION:
The shift from centralized power generation to a distributed network of smaller-scale renewable energy sources, reduces reliance on large power plants.
E
ELECTRIC GRID:
The interconnected system of transmission lines, substations, and transformers deliver electricity from power plants, including renewable energy sources, to consumers.
F
FREE ENERGY:
Referring to the renewable and abundant source of energy provided by wind turbines, harnessing the power of wind for electricity generation without fuel costs.
G
GREENHOUSE GAS:
Gases such as carbon dioxide contribute to global warming and climate change. Wind energy contributes to their reduction by replacing electricity generation from fossil fuels.
H
HYDROGEN PRODUCTION:
Highlighting the potential synergy between wind energy and the production of hydrogen, a clean fuel with diverse applications.
I
INFRASTRUCTURAL DEVELOPMENT:
Describing the establishment of necessary infrastructure, such as transmission lines and substations, to support the integration and distribution of wind-generated electricity.
J
JOIN VENTURES:
Important partnerships between companies, organizations, or countries for the development and implementation of large wind energy projects.
K
KINETIC:
This refers to the kinetic energy used by e.g. vertical-axis wind turbines, which convert the kinetic energy of the wind into electrical energy.
L
LOCAL COMMUNITY:
Emphasizing the positive impact of renewable energy projects on local communities, including job creation, infrastructure development, and community engagement.
M
MEGAWATT:
Megawatts are used to assess and compare the energy output and performance of wind turbines, as well as to determine the scale and capacity of wind energy projects.
N
NATURAL RESOURCES:
Natural resources are materials or substances that occur naturally in the environment and can renew or regenerate themselves naturally over time. Examples include sunlight, wind, water, and biomass.
O
ONSHORE:
Describing wind turbines located on land, utilizing the power of wind for renewable electricity generation in terrestrial environments.
P
PHOTOVOLTAIC:
Photovoltaic technology refers to the process of converting sunlight directly into electricity using solar cells. Solar cells, typically made of semiconductor materials such as silicon, absorb photons from sunlight and generate an electric current.
Q
QUALITY CONTROL:
Refers to the processes and procedures implemented to ensure the reliability and performance meeting specified quality standards.
R
ROTOR:
Refers to the rotating part of a wind turbine, which consists of blades connected to a central hub and converts the energy of the wind into a rotary motion.
S
SMART GRID:
Refers to an advanced electricity grid infrastructure that includes digital communication and control systems to efficiently manage and integrate renewable energy sources.
T
TECHNOLOGY:
Advances and innovations in wind turbine technology, including blade design, control systems, and materials that improve efficiency and performance.
U
ULTRASONIC TESTING:
This is a non-destructive testing method that uses high-frequency sound waves to detect flaws or defects in wind turbine components to ensure their structural integrity and safety.
V
VERTICAL-AXIS:
Describes a type of wind turbine in which the main shaft of the rotor is vertical, allowing the turbine to capture wind from any direction, making it suitable for certain areas and environments with low wind speeds.
W
WIND RESOURCE:
The availability and quality of wind in a specific location, determining the feasibility and potential for wind energy generation.
Z
ZONE CONTROL:
Signifying the use of advanced control systems in wind turbines to optimize their performance, adjusting parameters based on specific operational zones and conditions.
