Energy Test Review

A debate between two students takes place regarding the environmental consequences of obtaining energy from nuclear power. One student argues that nuclear power is a clean and efficient source with minimal environmental impact, while another student claims that renewable energy sources are the best option. Which statement aligns with the environmental consequences of using nuclear energy?

• Renewable energy sources, like nuclear energy, have no negative environmental impacts.

• Nuclear power is an extremely environmentally friendly practice because it produces no waste.

• Nuclear power can result in long-term radioactive waste that has negative environmental consequences.

• Nuclear energy is a renewable energy source that has low efficiency and produces significant atmospheric pollution.

Nuclear energy is often argued to be a cleaner source of energy compared to fossil fuels. However, some people claim that this must mean that nuclear energy is a renewable resource. Which evidence would refute the claim that nuclear energy is a renewable resource?

• Nuclear energy does not release carbon dioxide.

• Nuclear energy is released from fission reactions.

• There is a limited supply of uranium ore on Earth.

• Nuclear power plants use steam to turn turbines in their energy production.

One way for a family to determine their energy use is by analyzing their electric bill each month. Most energy bills include a graph displaying energy use over the last 12 months. This allows people to consider their energy use and make adjustments if needed. Mr. Hernandez noticed his family's usage for this December was about the same as last December, even though they were gone on vacation for about a week and a half this year. Since they were not home for a portion of the month, he expected their energy usage would be significantly lower. He calls a family meeting to discuss how they can reduce their energy bill next December, when they take another family vacation. Which idea will reduce their energy usage the most, while also being reasonable to follow?

• For the time they are home during December, cook meals outside on the charcoal grill instead of inside with the electric stove/oven

• When they return from their trip, leave the television off for a week, and hang clothes up outside to dry instead of using their electric dryer.

• Before leaving for their trip, turn the central heating system off, along with lights and electrical household appliances that will not be in use.

• While they are home in December, they can use candles instead of electric lights, and put their food in coolers so they can unplug their refrigerator.

Many types of energy are harnessed to create electricity. Wind and solar power are examples of renewable sources, but petroleum is non-renewable. What fact explains why petroleum is considered non-renewable?

• Petroleum can only be generated from dinosaur excrement.

• Petroleum is manufactured from an element that no longer exists.

• Petroleum is only found in Saudi Arabia and they may refuse to sell to other countries.

• Although petroleum is a fossil fuel, created from plant and animal remains, the process takes many millions of years.

Choose if the statement strengthens the argument for solar energy.

• Solar energy can be produced locally in remote areas.

• The initial cost of solar collectors is still relatively high

• The cost of solar energy will continue to decline as production is increased.

• Solar panels take up a lot of space compared to other energy sources.

• Solar energy has a high energy yield and can be used almost anywhere including rooftops.

Regina just graduated from college and is open to move anywhere in the U.S. She wants to move somewhere that is environmentally conscious and will allow her to live a lifestyle that reduces her carbon footprint. She already has an electric car and plans to use it to travel to work. Based on the information below, which area would be the best fit for her?

• Portland, Oregon, new homes will be built with solar panels reducing energy needs on coal and oil

• In Honolulu, Hawaii, transportation by scooters has increased by 20%

• Miami, Florida, legislation is being passed requiring bike lines on many roads

• Nashville, Tennessee, many buses are converted to natural gas

Roughly about 80% of energy usage today comes from fossil fuels. These non-renewable energy sources are being consumed at an alarming rate. Since they are non-renewable, once they are gone, they are gone forever. It takes millions of years to create fossil fuels. The graph above shows the estimated amount of time three of the most popular fossil fuels have left before they run out if consumption continues at the rate it is at currently. Which strategy is most likely to help extend the life expectancy of our fossil fuels?

• A. Begin using more oil for energy instead of coal

• B. Develop technology that detects even the most minute amount of fossil fuels

• C. Pass legislation to allow for more construction of gas stations along the interstates

• D. Pass more legislation to construct and utilize more renewable energy sources such as hydroelectric and wind power
