P3 Energy Resources Flashcards
What is a non-renewable energy resource?
will eventually run out, is not replaced at the same rate it is being used
What is a renewable energy resource?
will not run out, it is being (or can be) replaced at the same rate as 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 to extract and use
What are the main disadvantages of using coal as an energy resource?
will eventually run out, releases CO, 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 produced, no waste products, low running cost, no fuel costs
What are the main disadvantages of using wave turbines?
unreliable, dependent 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 using wind turbines?
unreliable, dependent on weather, cannot control supply, take up lot of space, can produce noise pollution
What are the advantages and the disadvantages of using geothermal energy?
advantages: no polluting gases, low running cost disadvantages: initial set up expensive, available in few locations
