Why is natural gas a better energy source than oil and coal?
It produces fewer greenhouse gases.
It is renewable.
It is not a natural resource.
The graph shows how the capacity to produce energy from wind power has increased over the past 20 years. Which statement produces the best explanation for the trend?
Wind power has been increasingly used in energy production because average wind speeds have almost doubled in the last 20 years.
Wind power has been increasingly used in energy production because the electricity it produces has a higher wattage for powering homes than electricity from other sources.
Wind power has been increasingly used in energy production because it is renewable and creates less air pollution than other forms of energy production.
Wind power has been increasingly used in energy production, while total capacity for nearly all other forms of energy production has decreased.
Which statement describes the depletion of a nonrenewable resource through human processes?
Fossil fuels from plants and animals living 300 million years ago are extracted from the ground for use as an energy source.
Water falls from clouds as raindrops and lands in a river, where it flows over a dam to create hydroelectric power.
Plants absorb the carbon dioxide exhaled by animals and use it to perform photosynthesis, releasing oxygen back into the air for animals.
Topsoil forms slowly to replace soil that has been removed from the bank of a river by erosion from the river's flowing water.
Which activity uses a nonrenewable resource?
heating a building with solar panels
building a house with timber
driving a car that uses gasoline
pumping water with wind power
Why are fossil fuels considered nonrenewable?
They are replenished by processes that take millions of years.
They are formed from living things.
They are only found in limited quantities.
They cannot be replenished.
Amy lists 3 possible environmental impacts from energy resource consumption. Which energy resource most likely produces all 3 listed impacts?
fossil fuels
geothermal energy
hydroelectric
nuclear energy
What is one benefit of using renewable resources to produce energy?
Renewable resources cannot be used up permanently.
Renewable resources are available everywhere.
Producing energy from renewable resources is easy.
Producing energy from renewable resources relies on weather.
Examine the table showing time taken to replenish a resource. Which resource would most likely be considered renewable?
Resource A
Resource B
Resource C
Resource D
The table lists the features of several energy sources. Which statement can be inferred based on the information in the table?
Only non-renewable energy is available 24 hrs/day.
Renewable resources can be depleted if overused.
All renewable energy sources are available 24 hrs/day.
Non-renewable energy sources can be depleted if overused.
A student records 4 statements regarding resources. Which statement describes a renewable resource?
1
2

The town of Clarksville is reviewing options for energy with the goal of reducing their production of greenhouse gases. Increased use of which energy source would reduce the town's greenhouse gas production?
coal
natural gas
petroleum fuel
sunlight
What is one advantage to using fossil fuels as a primary energy source?
Fossil fuels are made from decaying plant and animal remains in a short period of time, making them a good energy source.
The technology for fossil fuel combustion is well understood, and the energy can be produced relatively cheaply.
Fossil fuel combustion creates less pollution than getting energy from hydroelectric, solar, and nuclear energy sources.
There is no way to store energy made from other sources, but fossil fuels can be combusted 24 hours a day.
Hydropower generates over 60% of the world's renewable energy. What could be an environmental impact of this method of power generation?
It emits greenhouse gases.
It produces air pollutants.
It contaminates groundwater resources.
It results in the destruction of plant and animal habitats.
What are the environmental concerns for wind turbines?
increased temperature
increased noise pollution
increased radiation
increased greenhouse gases
