Some people argue that replacing gasoline with biofuels is an important step in transitioning from fossil fuels to renewable energy that must be completed right away, especially because we have the technology and resources to do it. While this argument may hold some validity, what drawbacks might these people be overlooking when making this argument? (Select the three correct answers.)

One of the major concerns about current first-generation biomass fuels is that they take a lot of energy to produce and therefore won't help to reduce the emissions of greenhouse gases. Let's see if this is true in the following example: A gallon of gasoline releases about 9 kg CO2 when burned. If it takes about 2 kg of coal to produce the electricity to make one gallon of biofuel and each kilogram of coal results in the emission of 3.75 kg CO2, how much would CO2 emissions be reduced or increased by using biofuel instead of gasoline? You can assume that a gallon of biofuel and a gallon of gasoline have exactly the same amount of energy in them.

The Paris Agreement commits countries, including the United States, to a reduction in CO2 emissions. Which of the following actions would be the most likely to reduce CO2 emissions from the U.S.?

In what ways do government policies inhibit the widespread use of solar and other renewable energy sources?

While most of the major rivers in the United States could not support additional hydropower dams, which of the following statements describes a viable, cost-effective, and decentralized alternative that would still harness hydropower?

One day you are chatting with a friend about the environmental benefits of integrating large-scale renewable energy into the current power generation system. Your friend is skeptical and argues that there are well-documented impacts on wildlife and wildlife habitats How could you respond to demonstrate some of the positive benefits of renewable energy while balancing the environmental impacts that your friend mentions?

You know that the U.S. power generation system is fragmented; in fact, it is actually separated into three major grids with few connections between sections. However, you are wondering why these three grids don't just become separate grid systems that remain centralized but run completely on the renewable resources that are available in each respective section. What major issue still stands in the way of this plan to implement renewable power on a large, centralized scale in the future?

Even if the production of renewable energy sources increases quickly, these technologies are not likely to overtake fossil fuels as the major source of global energy over the next decade. Why?

Which of the following statements is an accurate characterization of a potential benefit of second-generation biomass fuels as an energy source?

How could batteries help address some limitations of renewable energy?

Hydrogen power can be a renewable source of energy for transportation, but in some cases, it may not be much better than the use of fossil fuels. Why is this the case?

_________ is emitted as a result of electricity generation in a hydrogen fuel cell?

Which of the following is NOT a barrier to incorporating renewable energy technologies at a large scale in the United States?
