Why do nonrenewable energy sources typically take a longer time to replenish than renewable energy sources do?
A characteristic of nonrenewable energy sources that distinguishes them from renewable energy sources
The Chernobyl nuclear disaster led to the release of massive radiation, specifically and which has been connected to a variety of environmental problems in the years following the disaster.
A meltdown in the Reactor core structures at a nuclear power plant, such as Chernobyl, would most likely lead to the accidental release of rad
Cogeneration is an example of which of the following processes?
An industry uses natural gas for manufacturing and uses the waste heat to produce electricity
What is the current recommendation of Congress for the permanent storage of high-level radioactive waste in the United States?
Burial deep underground at sites remote from population centers
What are the three sources that supply the majority of commercial energy in the world today.
Coal, oil, and natural gas
What best describes a disadvantage of geothermal energy production?
Geothermal energy implementation in homes and businesses has a high upfront cost, and electricity is needed to operate pumps
What is extraction of natural gas by the process of hydraulic fracturing (fracking) most likely to result in?
Groundwater contamination
Biomass is (more/less) commonly used in the least developed countries than in highly developed countries.
More
Using biomass for energy production result in local deforestation is a negative consequences which is associated with what?
Most often associated with using biomass for energy production
What is an advantage of using natural gas, rather than oil, as a fuel?
Natural gas is cleaner because it burns more completely
What best describes the process of electricity generation at a nuclear power plant?
Nuclear power is generated through fission, which releases a large amount of heat. The heat is used to generate steam, which turns a turbine that powers a generator
What best describes a benefit of increasing the number of offshore wind farms rather than onshore wind farms?
Offshore winds farms will produce up to three times as much electricity as wind farms on land because of increased wind speeds offshore
What cells do Solar Energy use to generate electricity?
Photovoltaic cells
What is a disadvantage of using nuclear energy as a source of electricity?
Spent fuel rods must be disposed of properly
What are economic benefits of building large dams?
Storage of water for agriculture and domestic use and production of renewable energy
What is the best example of an energy storage element in a solar energy system?
The hot water tank in a solar hot water system
What is a negative consequence associated with photovoltaic solar cells?
The manufacture of photovoltaic solar cells involves toxic metals that can be released into the environment
What is Hydraulic fracturing, or fracking?
The pumping of highly pressurized water with a mixture of sand and chemicals into boreholes to create cracks within the rock in order to provide pathways for the release of gas and oil
What is a major limitation of using photovoltaic cells to generate electricity?
They do not produce as much electricity on cloudy days
Oil is currently proven global reserves are expected to be largely exhausted within the next 50 years.
True
Replacing coal-burning power plants with wind farms would reduce global greenhouse emissions.
True
Solar is renewable.
True
Uranium is considered an energy resource.
True
What does Geothermal Energy do?
Utilizes heat that is stored beneath Earth's surface to heat water and produce steam
Which of the following would be the best location for a wind farm with ten industrial turbines?
When they are arranged uniformly on a local farm that has fields and pastureland for dairy and grain production
