2.1 Flashcards
Renewable resources
A resource that can be replaced (or replenished) over time at the same rate that they are used, or does not abate at all
What sources of energy are considered renewable resources? (7)
Solar, wind, wave, hydro, tidal, thermal, biomass
What are non-renewable resources?
Resources that does not renew (replenish) itself at a suffice to rate for sustainable economic extraction
What sources of energy are considered nonrenewable?
coal, petroleum, natural gas, nuclear, oil, timber
What are the exceptions for reserves?
In some cases reserves may exist but it is not economically viable to extract them or the technology does not exist yet
What is the availability of non-renewable resources and what is its relation to the frequency at which designers use them?
There is a finite amount of non-renewable resources, yet there is a high human dependency on them
What are reserves?
A natural resource that has been identified in terms of quantity and quality and can be economically and technically extracted
What is the impact of the extraction of resources on local populations?
1.Increase in wage gaps (companies that are paid to develop a resource in a country can bring wealth and employment opportunities - but it would increase wage gaps because most wealth from extraction leaves the country)
2.Mining for rare earth minerals generates large volumes of toxic and radioactive material
What are examples of reserves? (5)
Deepwater drilling for oil
Extraction of gold
Lithium
Fracking
Oilsands
What is the economic/ political importance of reserves? (5)
1.Setup costs (typically high + require funding support from multinationals)
2.Efficiency of conversion/ sustainable and constant supply (needs to be economically + technologically feasible to extract)
3.Social impact (bringing employment)
4.Environmental impact (toxic fumes)
5.Decommissioning (the plan for when the resource is depleted - how will the infrastructure, communities and natural environment be protected)
Renewability
The degree to which a resource is renewable
