Apes Non-Renewable Energy

When global demand for oil exceeds the rate at which is is produced;

• Price decreases and demand goes up.

• Price and demand stay the same.

• Flow rate is stopped.

• Flow rate to consumers goes down and price goes up.

• Flow rate to consumers goes up and price goes down.

Which of the following best describes net energy?

• Waste heat energy from a coal-burning power plant used to heat greenhouses.

• Total energy available, minus the energy needed to find, extract, process, and deliver the energy.

• Total energy produced from refined petroleum products.

• Energy used to move control rods in a light water nuclear reactor.

• Total energy collected in the filters of emissions towers in coal-fired power plants.

Which of the following is a benefit of using natural gas?

• It is four times as energy efficient as coal.

• It is cleaner-burning than coal.

• Coal power plants are cheaper to build and maintain than natural gas.

• Getting natural gas from Canada is inexpensive.

• CO2 is not released when burning natural gas.

Coal has a huge environmental impact because of;

• The threat to human health due to air pollutants released when coal burns.

• The release of carbon, which contributes to global climate change.

• The fact that it is the most abundant fossil fuel.

• Its high cost, mostly to cover the transportation of coal to electric power plants.

• The use of new technology that makes coal safer and cleaner to remove from the earth and to transport to homes and industry.

Which of the following negative impacts is NOT associated with coal mining and burning?

• Fracking used during extraction contaminates water and is associated with earthquakes.

• Carbon dioxide and sulfur dioxide gases are emitted.

• Toxic heavy metals, such as mercury and arsenic, are released into the enviornment.

• Coal ash, which contains hevay metals and radium, is toxic and must be stored safely forever.

• Open- pit mining and mountaintop removal may be used to aquire reserves.

Nuclear power was predicted to supply 21% of the world's commercial energy. Which of the following is the most signifigant reason why this goal has not been met?

• Thermal pollution, which becomes a problem when nuclear power plants break down or must be dismantled.

• Approximately 75% of the available high quality energy is lost as waste heat.

• The small supply of enriched uranium- 235

• The lack of long-term storage facilities for high level radioactive wastes such as spent fuel rods.

• The high risk of accidents such as Fukushima in Japan in 2011, Chernobyl in the U.S.S.R. in 1986, and Three Mile Island in the United States in 1979.

Which of the following is a true statement about nuclear energy?

• It is created through a fission chain reaction in which neutrons split, releasing high amounts of heat.

• It is formed through nuclear fusion reactions, which create energy currents.

• It is formed from the breakdown of uranium into high- pressure steam.

• It is created from the oxidation reaction of the water.

• It requires the use of other fossil fuels to super heat the plutonium fuel and separate out the necessary neutrons for the reactions.

In a nuclear power plant, control rods;

• Are used to transport the spent nuclear fuel pellets into storage.

• Are moved in and out of the reactor core to regulate the rate of fission.

• Separate the reactor core from the turbine and condenser tower to keep radioactive materials from escaping.

• Are caused to spin by the high heat, thereby generating electricty.

• Are used to moderate water flow through the reactor.

How does hydraullic fracturing contribute directly to climate change?

• Not all methane released from this method is captured; some escapes into the atmosphere, where it is a powerful greenhouse gas.

• Fracking contributes to earthquakes, which can release deep pocklets of carbon dioxide as a result of the techtonic shifts.

• Fracking operations release extensive amounts of carbon dioxide, which contributes further to climate change.

• Fracking can contaminate groundwater through leaking pipes that are not monitored properly.

• Fracking causes people to burn more methane, which adds more carbon dioxide to the atmosphere.
