Energy, It can be transported long distances inexpensively and with very…

- - - - Gravity-driven hydraulic power plants water descends into a reservoir located at a lower height, then pumped to a higher reservoir to reuse it
      - Pump-driven hydraulic power plants water used follows the course of a river and will not be reused
- - - - A turbine converts mechanical energy into the rotating movement of a shaft.
      - An alternator has fixed a part, called a stator, and a moving part called a rotor, connected to the turbine shaft.
  - - - Transporting it by high voltage cables attached to towers
      - Decreasing the voltage at the electricity substations to 3-30kV.
      - Increasing the voltage to 220000V or 400000V to prevent significant energy loss, due to the Joule effect.
      - Distribution to homes, offices, industries and public facilities. During this stage, the voltage is reduced to 230-400 V.
- - - - Resulting from transformation of primary sources
    - - Obtained directly from nature
  - - - Sources that have negative effects on the enviroment
    - - Low environmental impact
      - Don´t generate by-products that pollute the enviroment
  - - - In early stages of their technological development
      - Solar and wind power belong to this group
      - Alternative energy sources
    - - Most commonly used in industrialised countries
  - - - Abundant and inexhaustible
    - - Depleted when we use them up
      - Cannot be renewed in a short period of time
      - May or may not be abundant
- - - - adoption of more enviromentally friendly habits
      - essential to reduce the consumption of all forms of energy without seriously affecting quality of life
    - - use of renewable energy sources in fundamental
      - objetive is to produce a large part of our electricity through alternative power plants
    - - noticeably reduce the energy we consume
      - energy efficiency policies increase efficiency of everyday appliances and devices
  - - - Renewable
      - Reduces dependence on other fuels. Clean. Possible domestic production
      - Visual and sound impact. Non-polluting
      - Low levels of performace. Discontinous and random. Risk of accidents
    - - Renewable
      - Great capacity and performance
      - Change in natural enviroment.Some lands are underwater. Diverting on the natural course
      - Risk of disaster if a dam breaks. Risk of the dissapearance of flora and fauna
    - - Renewable
      - Reduces dependence on other fuels. Clean Possible prodution for use
      - Affects ecoystems as it covers large areas. Non-polluting
      - Low levels of performance.High instalation costs.Discontinous and random
    - - Non renewable
      - Great capacity and high performance
      - Danger of radiation contamination. Non recycable waste pollutants
      - Risk of radioactive emisions. Danger of nuclear disaster.Radiactive waste
    - - Renewable
      - Reduces dependence on other fuels.Reuses forestry and household waste
      - Beneficial if used correctly
      - Excesive exploitation of natural resources. Increases the greenhouse effects
    - - Non-renewable
      - Great capacity and high performance
      - -Atmospheric pollution from gas combution
        -Warm water released from the cooling system
      - Respiratory diseases. Increases the greenhouse effect. Negative impact on ecosystems
    - - Renewable
      - Reduces dependence on others fuels
      - Enviromental changes resulting from required construction work
      - Clean quiet
