Fossil fuel is formed by dead organisms (dead plants, dead animals, etc.)


Abe

Can it be used in the Netherlands or in Spain?

Netherlands:

It can be used in the Netherlands. But we are already using fossil fuels. In cars, boats, planes, etc. In the past we used also fossil fuels by mining coal. Nowadays we used fossil fuels plants to create energy

Spain:

It can be used in Spain, for the same reason as for the Netherlands. There are 66 fossil fuel plants in Spain.


Advantages and disadvantages

Advantages:

  • High amounts of elctricity can be generated
  • Transporting oil and gas is easy

Disadvantages:

  • It is not renewable
  • Pollution
  • We are running out of fossil fuels

Is it renewable?

No, fossil fuels are not renewable. When we burned them all we cant used them again. That is why we are trying to use other energy sources.

Pedro

Spain has 66 fossil power plants a 76% of energy of the country. And the Netherlands has 9 fossil power plants.

Effect on the environment

Fossil fuels are the largest greenhouse gas emitters in the world, contributing 3/4 of all carbon, methane and other greenhouse gas emissions. The real problem is that the atmosphere already absorbs a ton of greenhouse gases naturally, but is trapping up to 25 percent more of the sun's radiation due to annual increases in greenhouse gas emissions. Just think of the atmosphere as a very thick blanket of insulationthat grows thicker and more absorbent by the year. Here are some statistics:

  • 3.2 billion tons of additional carbon dioxide annually.
  • More than 2.5 million metric tons of carbon is produced by power plants.
  • 76% of Spanish energy production comes from non-renewable sources.

how does it work:

coal

The coal is thrown on an asembply line that goes into a grinding machine. With that grinding machine the coal is grinded adn thrown into a furnance. In that furnance there goes a pipe with cold water.The water is boiled so it becomes steam, the steam goes to the upside of the furnance. There the pipe continues and goes to a steam turbine. The turbine generates electricity and that electricity goes to a transformer. From that transformer the energy goes to a lot of places. After the steam turbine the steam cools down in a condenser and the water makes the same round ovr and over again with new coal.

oil

with oil electricity can be formed in 3 ways.

1: oil is burned and the rest is the same with coal.

2: oil is burned under high pressure and the exhaust gas is used to turn a turbine.

3: oil is combusted in a combusted turbine using the exhaust gas, after the exhaust gas is recovered it heats water for the same proces again
