A coal plant has the following characteristics: Generation capacity 600MW fuel efficiency 45% energy content 30 GJ per ton coal price 75 euro/ton CO2 emission factor 2.66 ton CO2 per ton coal if the electricity price is 50 euro per MWh, then what is the upper limit for willing to pay for CO2 emission?

an iron can weighing 50 grams absorbs 256.0 J of heat and warms by 11.4 degrees C. What is the specific heat of the iron can? (Formula: Q(heat)=mCpdetlaT)

In solar nuclear fusion, each time a proton fuses with another proton, this amount of energy is released   a. 1.44 MeV b. 5.49 MeV c. 26.72 MeV d. 12.86 MeV e. 2 MeV

predicts that coal will decrease from a 24% share of US electric generation in 2020 to a 13% share in 2050.  This is while the total annual US electric generation is predicted to rise from about 4000 billion kWh in 2020 to about 5400 billion kWh in 2050.  Growth in renewable energy sources are predicted to make up for the decline in coal-based electric generation. Using the figure of 1000 kg/MWh of CO2 , what is the expected reduction in annual CO2 emissions due to this decline in the coal-based generation?
