To further assess their carbon footprint, EcoTech Solutions decides to reduce emissions by 20% for both the EcoTab and EcoPhone. Determine the reduced carbon emissions, in metric tons of CO2, for each product after implementing this reduction.

Suppose you are an environmental analyst working for a global company, EcoTech Solutions, which produces electronic gadgets. EcoTech Solutions wants to assess and reduce its carbon footprint. You have gathered data on the carbon emissions produced during the manufacturing of two of their popular gadgets: the "EcoTab" tablet and the "EcoPhone" smartphone. The emissions data is presented in metric tons of CO2 per gadget produced. Here is the data you have collected:EcoTab Tablet: 0.75 metric tons of CO2 per tablet.EcoPhone Smartphone: 0.45 metric tons of CO2 per smartphone.EcoTech Solutions is committed to sustainability and wants to understand the environmental impact of its product line in more detail.

Consider a simplified representation of the production of power from coal fired power stations:• Bituminous coal (most common for power in Queensland) is burned in a furnace where most of theenergy liberated by the combustion reaction is transferred to a power cycle.• Heat transferred to a power cycle is converted to shaft work via a power cycle.• Shaft work is converted to electrical work for the grid via a generator and transformer.• Electrical work is transported through the grid to a home.Based on this simple representation, we are going to determine the carbon footprint of 1 MWh ofelectricity delivered to a household. To do this, we will assume:Step EfficiencyHeat from combustion to shaft work 38% (based on HHV)Conversion of shaft work to electrical work in the grid 95%Delivery of electrical work from the power plant to a household 90%a) Draw a simple block diagram of the energy flows and transformations for power generation. Start withthe heat from the coal combustion and finish with the household. You only need shaft work, electricalwork, and heat as the energy transfers in your diagram.Quantify each energy transfer on your diagram to deliver 1 MWh to a household and put this on yourdiagram.b) What are typical ranges for the calorific value (HHV) for bituminous coal (in MJ/kg) and the carbonintensity of bituminous coal in terms of:• kg CO2e per kg of coal, and• kg CO2e per MWh (HHV)Please use high quality references for this information and reference clearly at the end of the question(not at the end of all the questions). Identify a “typical” number for kgCO2e per MWh (HHV) to usein the next question.c) What is the carbon intensity (in kgCO2e/MWh) for electricity delivered to a household? Use mid-point estimates from above, and assuming that the embedded emissions for coal (i.e. pit to gate) are20 kg CO2e per MWh (HHV) and other smaller embedded, direct and indirect emissions are about10 kg CO2e per MWh (HHV).
