Practice FRQ 6.1 (Renewable Vs. Nonrenewable Energy Sources) Explain whether or not biomass is a renewable energy source. Justify your answer. Answer: Biomass is a renewable energy source because it comes from decayed matter of organisms. With the exception of mass extinction events, there should always be a steady supply of new organic matter that is naturally replenished as organisms due off. This makes biomass an energy source that can be renewed/replenished.

Calculate the percent change in renewable energy investment in the US from 2005 to 2018. Experts estimate that for the US to reach 100% renewable energy in 2050, it will require $7.8 trillion. Calculate the percent change this would represent from the 2018 investment level of $46.5 billion. Answer: The percent change in renewable energy investment in the US from 2005 to 2018 is 308%. The percent change this would represent from the 2018 investment level of $46.5 billion is 166.7%.

Explain TWO environmental benefits of using natural gas as a fuel compared to using coal. Answer: Using natural gas instead of coal produces less CO2 when burned to produce electricity. This reduces the amount of CO2, a greenhouse gas, in the atmosphere, slowing global warming. Natural gas also produces little to no particulate matter. This r
