Energy

We will learn a new unit called Energy. Before we begin, I'm going to solve the next answers:

1.What is the difference between a form of energy and an energy source?

      Because with energy sources we can generate different forms of energy .

2.Can you name an energy source?

      The sun, the uranium...

3.What is a renewable energy source?

      Renewable enegy sources come from natural resources that we cannot use up completely. These include hydroelectric, solar, marine, geotermal and biomass resources, as well as energy that we can produce from solid urban waste.

4. Where do oil, gas and coal come from?

      They come from fossil fuels, include in non-renewable energy sources.

5. What types of power stations do you know?

       Thermal power stations that use fossil fuels, combined-cycle power stations, nuclear power stations, wind farms, hydroelectric power stations, solar power stations, biomass power stations, marine power stations and geothermal power stations.

6. How is electricity transported from a power station to your home?

       First they have to raises the voltaje and then routing for high voltage and the lines are installed on towers. Before this procces, the substanctions use transformers to reduce the power to lower voltages. Finally, the power is distributed to homes.

7.  What do the terms "greenhouse effect" and "acid rain" mean? How are they related to energy production?

         Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions.

        The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.


8. What other points could you add to your poster or leaflet?
         Environmental consequences.
