Question

an engineer analyzes three years of data about one countrys consumption of renewable energy sources. renewable energy consumption: 3 years key year 1 year 2 year 3 from which renewable energy source(s) did this country consume more than 2.0 quadrillion btu each for year 1, year 2, and year 3? a biodiesel, ethanol, geothermal, solar, waste biomass, wind, and wood biomass b ethanol, hydroelectric power, wind, and wood biomass c hydroelectric power only d hydroelectric power and wood biomass only

Explanation:

Step1: Analyze each energy source

Check each renewable energy source (Biodiesel, Ethanol, Geothermal, Hydroelectric power, Solar, Waste biomass, Wind, Wood biomass) for all three - year (Year 1, Year 2, Year 3) consumption values.

Step2: Compare with 2.0 quadrillion Btu

For Biodiesel: All three - year values are less than 2.0 quadrillion Btu.
For Ethanol: All three - year values are less than 2.0 quadrillion Btu.
For Geothermal: All three - year values are less than 2.0 quadrillion Btu.
For Solar: All three - year values are less than 2.0 quadrillion Btu.
For Waste biomass: All three - year values are less than 2.0 quadrillion Btu.
For Wind: In Year 1, the value is less than 2.0 quadrillion Btu.
For Hydroelectric power: The values for Year 1, Year 2, and Year 3 are all greater than 2.0 quadrillion Btu.
For Wood biomass: In Year 1, the value is less than 2.0 quadrillion Btu.

Answer:

C. Hydroelectric power only
