Instructions: Read each scenario carefully to answer the computational questions.

Q1. A geothermal plant produces 35 MW (megawatts) of electricity continuously. How many MWh (megawatt-hours) of electricity does it generate in 24 hours?

Q2. A conventional heating system uses 2,000 kWh (kilowatt-hours) of electricity per month, while a geothermal system uses only 800 kWh to heat an identical home to the same temperature. How much electricity is saved in one year by switching to geothermal?

Q3. A home with a conventional HVAC system costs $200 per month to heat and cool. A geothermal system costs only $90 per month. How much money is saved in one year using geothermal?

Q4. A geothermal heat pump system costs $20,000 to install. It saves the homeowner $1,500 per year in energy costs. How many years will it take for the savings to equal the installation cost? Round your answer to the nearest tenth.

Q5. A conventional heating system costs $10,000 to install and $2,000 per year to operate. A geothermal system costs $20,000 to install and $700 per year to operate. What is the total cost for each system after 10 years, and which is cheaper?
