Which of the following is NOT true about alternative sources of energy?

A) using solar energy requires a large investment in photovoltaic panels and other infrastructure
B) biomass energy can involve burning scrap wood and methane from landfills
C) ethanol is mostly produced from corn and sugar cane, which can also be foods
D) fuel cells use oxygen and hydrogen as a fuel

Solar energy does indeed require an initial investment in photovoltaic panels and infrastructure, but the statement is misleading in suggesting that this is a unique or particularly notable drawback compared to other energy sources. The cost of solar panels has been decreasing, making solar energy increasingly competitive with traditional energy sources. The other options (B, C, D) accurately describe aspects of biomass energy, ethanol production, and fuel cells, respectively.
