Chp16 Enviro Science Quiz

QuestionAnswer
Roughly what percentage of the world's energy production is from renewable sources? 13%
The fastest-growing energy source in the world's energy production is new renewables: solar, wind, and geothermal power.
One drawback of biomass energy is that its use can lead to deforestation.
Why is there little chance of expanding hydroelectric power much beyond its current level? Most suitable rivers have already been dammed.
How do photovoltaic cells generate electricity? Their semiconducting surface converts solar energy directly into electricity.
Which of the following is a factor contributing to the rapid growth of solar power use? No air pollution or greenhouse gases are produced in the generation of solar power.
Which of these is a major factor driving the expansion of wind energy? high energy returned on investment (EROI)
What provides the energy for generating geothermal power? heat from the Earth's interior heating water or rock near the earth's surface
When hydrogen is used in a fuel cell to produce electricity, what is a by-product? water
Which of these is NOT a reason for pursuing the current energy sources that are alternatives to fossil fuels? Fossil fuels are much more expensive.
Which of these can be Carbon neutral? ( Biomass Energy ) Biomass
Why is no growth expected for hydropower? ( Hydroelectric Power ) Almost all rivers that can be dammed for power generation have been dammed already.
Which of the following is NOT a drawback associated with the use of biomass energy? ( Biomass Energy ) Because they burn less cleanly than gasoline or diesel, ethanol and biodiesel contribute more to air pollution.
All these are sources of biomass energy EXCEPT ( Biomass Energy ) lignite coal.
Which energy source received the most federal funding from 1974 to 2005 for research and development? ( Renewable Energy Sources ) nuclear power
An example of passive solar energy use is ( Solar Energy ) building a house so that sunlight can get in through large windows in the winter but is blocked during the summer.
Of the renewable energy resources, which is growing the fastest? ( Renewable Energy Sources ) wind
Which of the following collect sunlight and convert it to electrical energy directly? ( Solar Energy ) photovoltaic cells
Which of the following statements about wind power is NOT true? ( Wind Energy ) Wind turbines take up large amounts of land unsuitable for other purposes.
Which renewable energy source is the most used worldwide? ( Renewable Energy Sources ) biomass
Which renewable energy plays the largest role in electricity production worldwide? ( Renewable Energy Sources ) hydroelectric power
Electrolysis is used to ( Hydrogen ) split water into hydrogen and oxygen.
How is geothermal power different from the other commercially used forms of renewable energy? ( Geothermal Energy ) It is the only one not based on the energy of the sun.
All of these are advantages of using solar energy EXCEPT ( Solar Energy ) Solar power is reliable and consistent.
