P3 - National and Global Energy Resources Flashcards
What is a non renewable energy resource
will eventually run out, is not replaced at the same rate at being used
what is a renewable energy resource
will not run out, is is being or can be replaced at the same rate at which it is used
what are the main renewable and non-renewable resources available on earth
renewable: solar, tidal, wave, wind, geothermal, biofuel, hydroelectric
non-renewable: coal, oil, gas, nuclear
what are the main advantages of using coal as an energy resource
enough available to meet current demand, reliable, can control supply to match demand, cheap fo extract and use
what are the main disadvantages of using coal as an energy resource
will eventually run out, release carbon dioxide which contributes to climate change, releases sulfur dioxide which causes acid rain
what are the main advantages of using nuclear fuel as an energy resource
lot of energy released from a small mass, reliable, can control supply to match demand, enough fuel available to meet current demand, no polluting gases
what are the main disadvantages of using nuclear fuel as an energy resource
waste is dangerous and difficult and expensive to deal with, expensive initial set up, expensive to shut down and to run
what are the main advantages of using solar energy
can be used in remote places, no polluting gases, no waste products, very low running cost
what are the main disadvantages of using solar energy
unreliable, cannot control supply, initial set up expensive, cannot be used on a large scale
what are the main advantages of using tidal power
no polluting gases, no waste products, reliable, can produce large amounts of electricity, low running cost, no fuel costs
what are the main disadvantages of using tidal power
can harm marine habitats, initial set up expensive, cannot increase supply when needed, amount of energy varies on time of month, hazard for boats
what are the main advantages of using wave turbines
no polluting gases produces, no waste products, low running cost, no fuel costs
what are the main disadvantages of using wave turbines
unreliable, dependant on weather, cannot control supply, initial set up expensive, can harm marine habitats, hazard for boats, cannot be used on a large scale
what are the main disadvantages of wind turbines
unreliable, dependant on weather, cannot control supply. take up a lot of space, can produce noise pollution
what are the advantages and disadvantages of using geothermal energy
advantages: no polluting gases, low running cost
disadvantages: initial set up expensive, available in few locations
