Which is the Spain community with the highest hydropower installed?
Castilla y León
Catalunya
Madrid
Andalucia
What is needed to extract energy from river water?
Only a dam
Nothing
A river or a swamp
Differents options are possible, a river with fast strong flow or a dam.
What's hydropower energy?
It's a power which generate hot
It's a renewable energy that collects energy from the wind.
It's a renewable energy that collects energy from the sun.
It's a renewable energy that take advantage from the kinetic energy of water.
What types of energy are obtained from hydraulic energy?
Heat
Heat and electricity.
Kinetic energy or electricity.
Nuclear energy
Which is the correct answer for hydropower advantages?
It's very economic
It's easy to use.
Is practically an infinite energy and it runs all the day (night and day).
It doesn't pollute the environment at all.
What's wind power?
It's an energy harnessed from the waves.
It's an energy generated from the wind.
It's an energy obtained from the sun.
It's an energy obtained from the movement of the water,
Which is the Spain autonomous community that produce the highest wind power energy?
Galicia
La Rioja
Castilla y León
Extremadura
When was the first wind turbine build?
In 1888
In 1889
In 1988
In 1999
Which one of these mechanisms can we find inside a wind turbine?
Motor
Disks brakes
Pluviometer
Wheels
Which of these options is a wind power disadvantage?
Ambiental pollution
High Cost
Noise pollution
It doesn't have any disadvantage.
Which energy is wave and tidal?
Wind
Sea water
Sun
Biomass
Tell me one advantage of wave and tidal
High energy density
It have a large upfront cost
Wave and tidal energy converters are located near the coastline.
It only works at night.
Tell me one Wave and Tidal energy curiosity
Clouds reflect 25% of the solar radiation that reaches Earth.
The United States has no tidal and wave power plants.
Spain is the fifth country in the world with the most installed wave and tidal energy,
It is the main source of energy in Iceland.
Tell me one disadvantage of wind & tidal energy.
It's a highly predictable energy source.
Environment friendly
They have low operational and maintenance cost.
It have a large upfront cost
How does wave energy works?
It uses the energy of the tides to produce electricity. In a tidal power plant, a dike separates a bay or estuary from the open sea. When the tide rises, the floodgates open and water enters the dike. At low tide, the floodgates open again and the water returns to the open sea, running the turbines of the power plant's electric generators.
The bubble is an energy converter that sinks a little more than a meter below the sea surface. Inside it has a piston that moves with the ripples of the waves and transmits the motion to an electric generator, producing the electricity that is sent to the sidewalk by means of an underwater cable.
Collects energy from the sun with photovoltaic panels.
it is generated by transforming the movement of air currents into electrical energy.
What's biomass
It's an energy obtained from the wind
It is obtained from the sunlight
It's obtained from burning plants or animal material
It's obtained from the inside of the earth.
How it's biomass energy obtained?
With a solar panel
It's obtained from wind mills.
From the controlled bacterial decomposition of organic matter.
Like orange juice.
Advantage of biomass
Reduce organic waste.
It emit CO2 when it's burned
It doesn't allow to reduce humans waste.
It produces more energy than other renewable energy sources with the same amount of primary energy.
Curiosities of biomass
Can't reduce risk of forest fires.
The most important biomass application is for produce cold and hot water.
Most of the electric energy in Spain is produced with...
Most of the electric energy in Spain is produced with oil.
Eolic is the renewable energy less used in Spain.
Gas natural it's no used on Spain.
Biomass energy is ones of the usest on Spain.
What is solar energy?
The most abundant energy source.
An energy that contaminates.
The less abundant energy source.
Solar energy don't exist.
Conditions that need to work correctly
Sun and that's it.
A cable.
A photovoltaic module, a charge controller, a battery and a 12/vdc inverter.
Nothing of these answers.
How it works?
Solar panels collect energy from the sun's radiation, transforming it into electricity.
With cristal.
With the light of the sun.
None of the top
What type of energy you can get from it?
Eolic
Solar
Hidraulic
Photovoltaic and thermal energy.
How much takes to the light to come to the earth?
8 minutes
A few seconds
5 minutes
120 minutes
