Currently, most high-level radioactive waste from nuclear reactors in the United States is
stored in deep ocean trenches.
reprocessed into new fuel pellets.
chemically modified into safe materials.
stored at the power plant that produced it
What is cogneration?
Getting electricity and useful thermal energy from a single fuel source.
Explain the process of how fracking releasing natural gas and oil
Fracking pumps high-pressure fluid into underground rock. This cracks the rock and releases trapped oil or natural gas.
Which of the following is a major reason why many developing countries continue to rely heavily on wood, charcoal, and animal waste as energy sources?

Which of the following best describes a subsistence energy source?
A. These are commonly used in urban areas of developed countries, where fossil fuels are widely available.
B. Examples include hydropower and solar power.
C. Examples include natural gas and nuclear power.
D. These are commonly used in rural areas of developing countries, where humans gather fuel for their own immediate use.
D. These are commonly used in rural areas of developing countries, where humans gather fuel for their own immediate use.
Which of the following best describes a benefit of increasing the number of offshore wind farms rather than onshore wind farms?
A Offshore wind farms will consume less water during operation than wind farms on land because the turbines require less steam for electricity generation.
B Offshore wind farms will decrease the maintenance costs associated with electricity generation because they are cheaper to operate than wind farms on land.
C Offshore wind farms will emit less carbon dioxide and carbon monoxide than wind farms on land because they are farther from urban areas.
D Offshore winds farms will produce up to three times as much electricity as wind farms on land because of increased wind speeds offshore.
Answer D Correct. Offshore winds are much steadier and faster than land winds because of a lack of obstruction by other vertical structures.
After the Industrial Revolution, the use of fossil fuels increased significantly. Despite the documented environmental effects of these resources and the availability of renewable resources, the use of nonrenewable sources continues. Which of the following statements best explains why there is continued widespread use of nonrenewable fossil fuels in energy production in the United States?
A Established technology and transportation infrastructure for fossil fuels allows these resources to be converted into energy to meet consumer demand.
B Fossil fuels are significantly cheaper than renewable resources, so they do not require government subsidies, which ultimately saves the government money.
C The environmental effects of fossil fuels are easy to mitigate, while the environmental effects of renewable resources are difficult to understand and reverse.
D Fossil fuels will always be present and are plentiful in quantity, so there is little pressure to find a replacement for them as an energy source.
A Established technology and transportation infrastructure for fossil fuels allows these resources to be converted into energy to meet consumer demand.
