HT.4.a.b Energy generation & Issues with generation

Electricity is a source of energy.

• True

• False

These types of energy production make steam to generate electricity

• Solar PV

• Geothermal

• Hydro-electricity

• Nuclear generation

• Wind Power

Select the correct order of energy conversions for thermo-electric generation

• Thermal > Chemical potential > Kinetic > Mechanical > Electrical potential

• Chemical potential > Kinetic > Mechanical > Thermal > Electrical potential

• Chemical potential > Thermal > Kinetic > Mechanical > Electrical potential

• Chemical potential > Thermal > Electrical potential > Kinetic > Mechanical

Thermo-electric generation can use the following energy sources...

• Coal

• Natural gas

• Uranium

• Wood

• Geothermal

Answer explanation

Whatever sources that can boil water can be used!

Fossil fuels are made from...

• Dinosaur fossils

• Ancient algae and plankton compressed with heat and pressure

• Geothermal layers in the Earth's crust

• Composted organic matter

Fossil fuels are popular energy sources because...(select all that apply)

• They have high energy density

• They cause climate change

• They can be stored for a long time

• They (have been) relatively abundant

• They can be stored relatively safely

"As fossil fuels get harder to find, prices at the gas pumps will fluctuate more, and generally increase."

This statement is an example of...

• Economic costs

• Environmental costs

• Societal costs

"An electric car requires raw materials such as lithium for its batteries and neodymium for its motors, which require mining and energy to produce."

This statement is an example of...

• Economic costs

• Environmental costs

• Societal costs

Answer explanation

However, many rare materials are also requires to build combustion cars, make their fuels, and to make other consumer electronics, too.

"Electric cars will not solve the issues of traffic congestion and the time required to travel to your destination."

This statement is an example of...

• Economic costs

• Environmental costs

• Societal costs

"Electrifying our industries with electric motors instead of combustion engines, powered by solar and wind farms, will require huge up front investments from society."
