P2 National And Global Energy Resources Flashcards
What is a non renewable energy resource?
An energy source that will eventually run out it is not replaced at the same rate as it is being used
What is a renewable energy resource?
An energy source that will not run out, it is being (or can be) replaced at the same rate as it is used
What r the main renewable and non renewable resources available on earth 🌍?
Renewable: solar, tidal, wave, wind, geothermal, biofuel and hydroelectric
Non renewable: coal, oil, gas and nuclear ☢️
What r the main advantages of using coal as an energy source?
Enough available to meet current demand, reliable, can control supply to match demand and cheap to extract and use
What r the main disadvantages of using coal as an energy resource?
Will eventually run out
Releases carbon dioxide
Which contributes to climate change
Releases sulfur dioxide which causes acid rain
What r the main advantages of using nuclear ☢️ fuel as an energy resource ?
Lots 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 r the main disadvantages of using nuclear fuel ⛽️ as an energy resource?
Waste is dangerous, difficult and expensive to deal with
Expensive initial set up
Expensive to shut down
Expensive to run
What r the main advantages of using solar energy?
Can be used in remote places
No polluting gases ⛽️
No waste products
Very low running costs
What r the main disadvantages of using solar energy?
Only available during hours of daylight
Cannot control supply
Initial set up is expensive
Cannot be used on a large scale
What r 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 r the main disadvantages of using tidal power ?
Can harm aquatic habitats
Initial set up expensive
Cannot increase supply when needed
Times the energy is available varies each day
Hazard for boats 🚤
What r the main advantages of using wave turbines?
No polluting gases produced
No waste products
Low running 💲 costs
No fuel ⛽️ 💲 costs
What r the main disadvantages of using wave turbines?
Unreliable
Dependant on weather
Cannot control supply
Initial set up expensive
Can harm aquatic habitats
Hazard for boats
Cannot be used on a large scale
What r the main disadvantages of using wind turbines?
Unreliable
Dependant on weather 🌦️
Cannot control supply
Take up a lot of space
Can produce noise pollution
