oil is a non-renewable source. state two others
- coal
- wood
- natural gas
- nuclear
- coal
- wood
- natural gas
- nuclear
state two reasons why the domestic sectors energy consumption varies
- might have a smaller population
- cost may be higher
explain one advantage of developing uranium as an energy source
- co2 not produced = doesn’t contribute to global warming
- a lot of energy produced by a small amount of uranium = help reduce transport costs
carbon footprint
land / greenhouse gases
state non-renewable energy sources
- natural gas
- oil
- uranium
example of renewable
wind
state one reason why the global demand for energy is increasing
- population growth
- increase in wealth / development
- increased industrialisation
- advances in technology
state two factors that impact the location of solar panels
- road access
- sunlight hours
- proximity to housing
explain 2 remains why rising global demand for products has lead to deforestation
- more space needed = manufacture palm oil products
- weak environmental laws = easy for palm oil companies to clear land
- profitable activity = companies who grow palm oil products
explain two reasons for lower fossil fuel oil prices in some years
- consumers attracted ti alternative energy = oil produces try + lure them back in
- price fall = demand fell = eg. GLOBAL FINANCIAL CRISIS
explain now reason why the rising affluence of a country can lead to a reduction in its carbon footprint
- more educated on issues + buy locally = reduce FOOD MILES
define renewable resource
can be used again
explain one reason why the energy consumption per person has increased in the last 100 years
- rising affluence = growth in consumerism of products that require electricity
- rising Car ownership = increases demand for oil
explain one reason why the energy consumption per person has increased in the last 100 years
- rising affluence = growth in consumerism of products that require electricity
- rising Car ownership = increases demand for oil
explain why non renewable energy sources need to be managed
- are finite = will run out = alternatives are needed that can be recycles = over a short period of time
- emit carbon dioxide = greenhouse gas = causes global warming = sea level rise
explain one way increasing energy production will effect environment
- deforestation to make way for oil extraction activities = increase rates of SOIL EROSION
- wildlife migration routes disrupted = by nouse from vehicles
one disadvantage of fracking
- produces greenhouse gases = global warming
- expensive = cost of energy will be high for consumers
- non-renewable = not a sustainable option
advantage of coal
- easily accessible = reduces costs for wanting to develop it = maximise profits
- cheap to mine = often located near surface =reduces costs
advantages of oil
- jobs are created = multiplier effect
advantages of nuclear
- efficient only small amounts are needed = reduces impact on environment through exploitation = long - term option
one disadvantage of solar panels
- solar energy = unreliable = sun does not shine all day = less energy produces = other energy resources are needed to meet the demand
- expensive = high start up costs = very few are built = not that much energy generated = only a small number of homes will benefit
describe hoe developing renewable energy will help us achieve sustainability
wind energy = replace coal to generate electricity = produces less carbon dioxide
explain the pressure that could result from global economic growth
high demand for for energy = increase prices eg. oil = may have to develop new areas
