A major limitation of using photovoltaic cells to generate electricity is that they

• do not produce as much CO2 as other energy sources do

• do not produce as much electricity on cloudy days

• have no moving parts

• cannot be connected to an electrical grid

Which of the following would be considered a disadvantage to using biofuels, such as ethanol, as a fuel source?

• There is a higher carbon emissions than petroleum alone

• The demands for biofuels is decreasing

• Ethanol requires a high energy investment due to processing the crops

• Ethanol gasoline freezes in gas lines in the winter at a lower temperature
