I need help with the questions in this worksheet

1MBTU1therm=1,000,000BTU=100,000BTU

1 MBTU 1 therm 1, 000, OOO BTU 100, OOO BTU Pounds of C02 emitted 59.8 lbs C02 Power Source A propane grill that bllrned through a full tank (430,270 BTU worth) of propane. An old-fashioned heater stove using coal to heat a house for a month (100 therms) A new furnace using natural gas to heat a house for a month (100 therms) Using 1 gallon Of gasoline (114,000 BTU) in a Windmill farm producing an average Of 50 Mega Watts of electricity for a year. The Point Beach Nuclear Power Plant, which generates 454 Mega Watts of electricity, operating for 50 years A laptop battery which discharges 100 Watt- hours Of energy. Electricity generation of Valley Power Plant operating for 1 year. Assume 280 Mega Watts electricity output, operating about of the time, produced using Natllral Gas with an efficiency of about 35%. Explain your reasoning: 430270 BTU x (1 MBTU 1 IOA6BTU) x 139 lbs C02 100 Therms x (1 Mbtu / 10 therm) x 216 lbs C02 = 21601bs C02
