What’s wind energy?
A renewable energy source that uses the power of the wind to generate electricity.
An energy source that works using photovoltaic panels that capture the power of the wind.
A non-renewable energy source that works thanks to the power of the wind.
correct answer
Wind energy is the energy that comes from the wind. Air has mass and when it’s moving, it creates kinetic energy due to airflow, which can then be turned into electricity. It’s a clean, endless energy source, so it reduces greenhouse gas emissions and protects the environment.

How's energy produced?
Wind turbines collect rainwater, turning it into electrical energy by way of a process called electrolysis.
The wind turbine blades capture solar energy, turning it into photovoltaic energy.
It’s produced by an electrical generator, through the effect of the air flow.
correct answer
When in movement, air masses have kinetic energy. The wind turbine blades are joined to a turbine rotor. As they’re pushed by the aerodynamic effect, they make the turbine rotor turn, transmitting this speed to the multiplier and producing electrical energy.

How’s the energy produced transferred to the network?
Wind farms evacuate the electricity produced from their transformation center to a distribution sub-center, to which they supply the energy produced and get it to the final user.
The kinetic energy is taken advantage of by the wind turbine blades, as it’s stored in thermal panels before being distributed to users.
Wind turbines supply energy directly to homes via gas pipes.
correct answer
Wind farms evacuate the electricity produced from their transformation center via a power line to a distribution sub-center, to which they supply the energy produced and get it to the final user (homes, factories...)

Can all the energy from the wind be used?
Yes, all vertical and horizontal currents can be used to obtain the necessary kinetic energy.
Only the vertical currents can be used.
No. Wind energy only works with horizontal currents.
correct answer
No. Wind energy only works with horizontal currents (vertical currents don't have the dynamic energy needed to take advantage), as long as their speed is greater than 3m/s and less than 25m/s.

How does a wind turbine work?
The turbine transforms kinetic wind energy into mechanical or electrical energy for practical uses.
The wind is transformed into electricity directly as the wind turbine blades turn.
The wind turbine blades absorb the heat from the sun, later turning it into electricity.
correct answer
The turbine or wind turbine transforms kinetic wind energy into mechanical or electrical energy for practical uses. Old windmills produced mechanical energy. Modern wind turbines produce electricity.

How long does it take to build a wind farm?
The maturation period of a wind farm is between six and eight years.
A year is enough time to build a wind farm.
Between three and five years.

Do wind turbines make noise?
Wind turbines aren’t noisy. The evolution of wind technology has made its mechanical noise almost unnoticeable.
Yes, but the environmental benefit they produce really makes up for this minor issue.
Yes, technology must be perfected over time to make them more silent.
correct answer
Wind turbines aren’t noisy. The evolution of wind technology has made its mechanical noise almost unnoticeable. The aerodynamic hum of the blades when they pass the tower is the main noise they make. Also, strict guidelines establish the permitted noise level, making it possible to stand underneath a turbine and have a conversation without having to raise your voice.

What makes onshore wind farms different to offshore wind farms?
Offshore wind farms are technically more complex to build and maintain than onshore wind farms.
Nothing, both have a similar cost and generate the same amount of electricity.
Onshore farms have greater capacity to generate electricity than offshore farms.

What was the main function of the first windmills?
Generate small amounts of electricity to facilitate agricultural world.
Mill wheat for human consumption.
They were military buildings used as surveillance towers.
correct answer
Grain milling was the first use for the windmill. They were originally used for onion skins and rice, milling malt, cocoa, mustard, pepper, and tobacco, extracting oil by pressing olives and linseed, and the extraction of oil from rapeseed and hemp seeds for ovens and lamps.

What other energies are considered renewable, besides wind energy?
Biomass, natural gas, wind, geothermal, petroleum and green hydrogen.
Wind, solar, geothermal, biomass, hydropower, and green hydrogen.
Solar, green hydrogen, geothermal, wind and natural gas.
correct answer
The energies considered renewal are solar, wind, geothermal, hydropower, biomass, and green hydrogen. There are three non-renewable energy sources: natural gas, coal, and petrol.
