The development of a nuclear power plant at an ocean site is expected to produce an enormous amount of electric power for a large population. Ocean water will be used to cool the plant and then returned to the ocean. What unintended consequence should be analyzed before starting construction?
number of kilowatts produced per home
the effect of warmed water on aquatic life
the impact of other energyproducing resources
energy use per person
Which best describes a disadvantage of using wind power to generate electricity?
The technology used to generate electricity from wind is expensive.
Much of the energy in wind power is lost when it is converted to electricity.
The source of wind needed to generate electricity is variable and unpredictable.
The amount of electrical energy produced from wind power is too great for power lines to withstand.
Which is the most negative environmental consequence of building dams for hydroelectric power?
air pollution
chemical spills
water pollution
habitat destruction
What can citizens do to conserve current energy sources for the future?
make disposable products
install solar panels to generate electricity
use new materials instead of recycled materials
increase the amount of material used to package goods
Which is an environmental consequence of using biomass
as a source of energy?
There are no environmental consequences for using biomass as a source of energy.
Biomass creates harmful emission of carbon and sulfur, and causes massive cutting of trees.
Biomass has a great impact on the temperature of fresh water and the amount of dissolved oxygen.
Why is solar energy seldom used as an environmentally safe energy source in households to provide electricity?
Solar energy can only be used with gasoline.
Solar energy is difficult to capture and store for later use.
Solar power facilities destroy animal habitats.
Solar power creates radioactive waste.
Some power plants release heated water into rivers. This
practice adds thermal energy to the river that most likely
threatens the existence of aquatic organisms.
keeps the river at balance with nature.
provides a better environment for native organisms to grow.
increases the amount of nutrients in the river.
Which is most likely the greatest impact on the environment when a dam is built for hydroelectric power production?
Animal populations increase rapidly in ecosystems upstream of the dam because of more available water.
Plant populations suffer from increased competition beyond the dam because more land is available for cultivation.
The water cycle is disturbed by the building of a dam because water is concentrated in new areas.
The dam destroys habitats by creating reservoirs of water that flood lands upstream of the dam.
Which practice should be used with nonrenewable energy
resources until affordable alternate energy options are developed?
depletion
stockpiling
conservation
preservation
Which would most likely be included in an environmental
impact statement concerning drilling for oil in Antarctica?
the estimated amount of oil sent to North America during the project
the effect of oil spills on organisms living in Antarctica
the effect of increased oil production on the economy
the costs of setting up drilling equipment
