Answer to Question 1

D

Answer to Question 2

Alternative sources for producing electricity include wind, solar, geothermal, tidal, and nuclear power. Oil could eventually be replaced by using biofuels such as ethanol (although corn-based ethanol is not a practical solution, as it requires too much energy to produce, and because it ties up land that might otherwise be used for food production).
