ENERGY - Coggle Diagram

- - - - Heat from solar radiation produces steam that moves rotor in generator
      - Uses speacial mirrors called heliostats
    - - Solar radiation transformed directly by panels of photovoltatic cells
  - - - Mechanical energy from tides and waves
      - Energy from ocean's thermal gradient
- - - - Depletion of resources, new ones needed
      - Sometimes harmful to the environment (timber)
    - - Oil into oil pipelines and oil tankers
      - Oil pipelines suffer accidents resulting in spills
      - Oil tankers have accidents at sea (oil spills) that can cause oil slicks
    - - Conventional thermal power plants produce air pollution (increase greenhouse effect), emit acids that cause acid rain...
      - In nuclear thermal power plants nuclear accidents can happen and produce nuclear waste
      - Water reservoirs for hydroelectric power plants change natural cycle of rivers, flood large areas, destroy ecosystems...
    - - We use energy that has caused environmental damage during extraction, generation and transpotation
  - - - Coal as a low sulphur content to reduce acid rain
      - Increase and maintain forested areas because the absorb carbon dioxide
      - Special filters on the pipes to capture gas pollutants
- - - - Transporting it by cables attached to towers
      - Decreasing voltage at electricity substations to 3-30kW
      - Increasing the voltage to 200 000V or 400 000 V
      - Distributions to homes, industries... with voltage 230-400 V
- - - - Performs better than ones with one cycle
      - Two cycles: one uses air and gas, the other is a conventinal thermal cycle
