Assuming that aluminium has an embodied energy of 211.51 GJ/tonne. Calculate the lifecycle greenhouse emissions (in g CO2-e) and costs (in USD) associated with producing 1 tonne of aluminium using electricity generated from the following sources:

SOURCE	Estimates of life cycle GHG emissions (g CO2-e per kWh) (Source: Amponsah et al. 2014)	Median overnight cost of energy generation (USD per kWh) (Source: IEA 2020)
Coal	888	1785
Natural Gas	499	1092
Hydro	75	2778
Solar PV	300	923
Geothermal	78	6647
Wind (Onshore)	124	1439
Nuclear	24	3370

Plot a graph to explore which source(s) of electricity represents the best choice for aluminium production when balancing costs and carbon emissions. Explain briefly what your graph shows and which electricity source you would recommend for an alumina refinery concerned with cost and carbon emissions.
