Energy demand Flashcards
(11 cards)
What are the three main reasons why global demand for energy is increasing
-i… population: more e… is needed
-e… development: increased w… means buying more things that require e…
-t… advances: more d… are created which need e…
-increasing population: more energy is needed
-economic development: increased wealth means buying more things that require energy
-technological advances: more device are created which need energy
Pros and cons of mom renewable resources
Pros:
-countries with f… reserves save m… as they don’t have to i… it
-this created large i… which e… millions of p…
-they are r…
-less u… is needed than f… fuels so less m… is needed
-g… is less p… than other fossil fuels
Cons:
-they will r… out
-we are r… to heavily on them which could lead to e… shortages in the f…
-m… can be very dangerous due to risks of f… and c…-ins
-mining and d… removes soil and v… which destroys h… and reduces b…
-burning f… fuels releases … and other greenhouse … causing … warming
-n… waste can be extremely d… to the environment as it is hard to … of
Pros:
-countries with fuel reserves save money as they don’t have to import it
-this created large industries which employ millions of people
-they are reliable
-less uranium is needed that fossil fuels so less mining is needed
-gas is less polluting than other fossil fuels
Cons:
-they will run out
-we are relying to heavily on them which could lead to energy shortages in the future
-mining can be very dangerous due to risks of flooding and cave-ins
-mining and drilling removes soil and vegetation which destroys habitats and reduces biodiversity
-burning fossil fuels releases CO2 and other greenhouse gases causing global warming
-nuclear waste can be extremely damaging to the environment as it is hard to dispose of
Pros and cons of renewable energy resources
Pros:
-will never r… out
-j… are created in i… developing r… energy resources
-don’t release … or other … gases
-require a lot less w… to run than non-r… so there is a l… chance of w… shortages
Cons:
-can be very … as the technology is still being d…
-unreliable
-solar … are made with t… chemicals which can harm the … when being m…
-h… can be destroyed to make r… for these r… resources
Pros:
-will never run out
-jobs are created in industries developing renewable energy resources
-don’t release CO2 or other greenhouse gases
-require a lot less water to run than non-renewable so there is a lower chance of water shortages
Cons:
-can be very expensive as the technology is still being developed
-unreliable
-solar panels are made with toxic chemicals which can harm the environment when being mined
-habitats can be destroyed to make room for these renewable resources
What is fracking
Where natural gas is extracted from being trapped in shale rock underground
How does fracking work
-l… is pumped into the … rock at high p…
-this causes the rock to c…, releasing the g…, which is c… as it come out of the w…
-liquid is pumped into the shale rock at high pressures
-this causes the rock to crack, releasing the gas, which is collected as it come out of the well
Negative impacts of fracking on the environment
-shale has releases … when it’s b… causing … warming
-c… used in f… liquid may p… the air and w…
-it uses a lot of w… which is l…
-shale has releases CO2 when it’s burned causing global warming
-chemicals uses in fracking liquid may pollute the air and water
-it uses a lot of water which is limited
What is the energy mix of a country
Is the proportion of energy that t gets from different sources
What is the best supply of energy in the uk
Gas
What does the energy mix of a country depend on
Population:
-the more p… the more e… that is needed
-fossil f… have become more a… as they are c… and produce energy q…
Wealth:
-d… nations have a h… energy c…
-renewable e… farms and plants are e. to build
-can’t always a… energy i…
Availability:
-some countries have a much greater a… to certain r… than others
Population:
-the more people the more energy that is needed
-fossil fuels have become more attractive as they are cheaper and produce energy quicker
Wealth:
-developed nations have a higher energy consumption
-renewable energy farms and plants are expensive to build
-can’t always afford energy infrastructure
Availability:
-some countries have a much greater access to certain resources than others
Attitudes towards energy resources

-controlling o… reserves gives TNCs lots of p… and wealth, which means they may l… money if there is a s… towards r… energy

Governments:

-in d… countries governments are facing p… from c… to protect the e…
Individuals:
-many favour non-renewable as they provide a cheap reliable supply of energy
-as fossil fuels run out we will have to rely on renewable resources however this can increase the price of energy, which people may oppose
-some favour renewable as environmental awareness increases
Organisations:
-big TNCs invest lots of money into the energy sector
-controlling oil reserves gives TNCs lots of power and wealth, which means they may lose money if there is a shift towards renewable energy
-sustainable energy needs more investment than fossil fuels, so less may favour renewable energy
-environmental organisations campaign against fossil fuel extraction and use because of its negative environmental impacts
Governments:
-want cheap reliable energy supplies leaning them towards non-renewable energy resources
-some governments want to secure energy supplies in the long term so lock at developing renewable resources for the future
-in developing countries governments are facing pressure from consumers to protect the environment
