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.

Advocates of drilling for oil in the Arctic National Wildlife Refuge (ANWR) believe that by using the oil found herewe would decrease our dependence on imported oil. However, opponents feel that;

• Tundra ecosystems recover quickly and can handle the stress of extracting the resource.

• There is relatively little oil so it is not worth degrading this fragile ecosystem.

• Since the oil is an estimated 20-year reserve, we should do more research into this resource.

• As demand goes up, we will not need this resource.

• A switch to renewable energy will eliminate the need for America to use this resource.

Oil as an energy source has all of the following disadvantages EXCEPT;

• OPEC controls much of the word's crude oil and is therefore able to control the price of oil.

• The posibility of oil tanker leaks and spills such as what occured with the Exxon Valdez.

• The loss or degradation of habitat if a leak develops in the pipelines used to transport oil.

• Depending on consumation, proven and unproven oil reserves could last more than 100 years.

• The possibility of accidents on offshore platforms, which could pollute water from oil spills and pollute air from fires.

The three largest users of coal are;

• China, The United States, and India.

• China, The United States, and Mexico.

• Russia, The United States, and Mexico.

• Russia, China and India.

• Saudi Arabia, Japan, and China.

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.
