| base
power |
- the amount of power
necessary to meet minimum demands of customers. A
base load power station is usually available 24 hrs a day, 7 days a week
and operates at full power most of the time.
6
ways of providing base load power from wind. |
| blade |
- the winglike part of the turbine. Most turbines
have 2 or 3 blades. |
| electricity |
- a flow
of charged particles, which may be electrons or ions. It is measured in watts or kilowatts |
| energy |
- the strength to
move or do something. We get our energy from food. Plants get energy from
sunshine. Cars get their energy from fuel: gasoline, or plants, or batteries.
In this website we are talking about the wind providing the energy to
make electricity. |
| generation |
- the conversion
of other forms of energy, such as the wind, into electrical energy through
special equipment. Check out this animation of a wind turbine generator |
| grid |
- an interconnected
power transmission network that delivers electricity from the power source
to your house, and other customers. It includes a power source, high voltage
transmission lines, power pole, transformers,and lines to your house. http://www.windpower.org/en/tour/grid/index.htm |
| kWh |
-an unit of energy
equal to one kW applied for one hour.
One unit of electricity
is 1kWh (one kilowatt-hour), "kilo" means thousand, so one kilowatt-hour
is the amount of electricity used by an 1000W appliance running for 1 hour. |
| load |
- the moment-to-moment
measurement of power consumption of the entire system
- also force
and weight that a structure is designed to withstand. |
| nacelle |
- the box behind the blades, holding the equipment that turns the wind motion
into electricity |
| non-renewable
energy |
-an
energy resource that can not be replaced once it is used up. Examples include fossil fuels such as oil,coal, and natural gas. |
| power |
-
the ability to perform work or produce a change to a condition. Power is
a flow rate of energy, or a rate of use of energy. We can't store electric
power, but we can store electrical energy. |
| renewable
energy |
- an energy
resource that will not run out. Examples are sun, wind, wave, biomass, and geothermal. |
| rotor |
- the blades and the hub of a wind turbine |
| tower |
- a tall structure that supports a wind generator |
| transmission |
- the
transportation of energy along a network or grid of
power lines |
| turbine |
- machine
for generating rotary mechanical power from the energy
of a moving force (such as wind, water, or steam). Turbines spin 2 or 3 blades connected to a rotor that turns a generator to make electricity. Photo |
| watt |
- a unit
for measuring electricity |
| wind |
- the movement
of air caused by the uneven heating of the earth's surface by the sun. |
| wind
rose |
- a drawing that shows
the information about the distributions of wind speeds, and the frequency
of the varying wind directions. See an example from the Danish Wind Industry Association. |
| wind
farm |
- a group of wind turbines used to generate electricity. |
