Renewable and Non-renewable energy

Which of the following is true regarding non-renewable energy?

• These are energy sources that never renew, so when they are used up they are gone forever.

• These are energy sources that take millions of years to renew, and we are currently using them at a rate faster than they renew

• These are energy sources that take thousands of years to renew, and we are currently using them at a rate faster than they renew

• These are energy sources that renew in a few years, but cause pollution and other environmental issues.

Which of the following is true regarding renewable energy?

• They are resources such as solar, wind, tidal, and geothermal that are highly abundant, clean, but very expensive.

• They are resources such as oil and gas, which take many years to renew.

• They are resources such as solar, wind, tidal, and geothermal that are highly abundant and available everywhere

• They are resources that are highly abundant and very cheap to use since they are so readily available..

Which of the following are fossil fuels? CLICK ALL THAT APPLY

• Natural Gas

• Oil

• Solar

• Wind

• Coal

Which of the following are examples of renewable energy? (CLICK ALL THAT APPLY)

• Oil

• Tidal

• Solar

• Geothermal

• Coal

Which of the following energy sources is responsible for smog?

• Coal

• Gas

• Nuclear

• Oil

Burning of this energy source is responsible for the major of greenhouse gas emissions such as CO2 (carbon dioxide)

• Plastic

• E-waste

• Oil and Gas

• Coal

Which of the following best explains how solar energy works?

• We harness energy straight from the sun's core with orbiting satellites, and that energy is transferred here through radio waves

• Photons (light energy) from the sun enters earth's atmosphere, and these light particles react with particles on earth. When these particles collide with one another energy is released

• When the sun's rays react with earth's magnetic field, it generates electricity.

• The heat from the sun warms solar panels, and the heat generated from the solar panel is what we use.

How is the concept of tidal energy and wind energy similar?

• They can both be used anytime and anywhere on earth

• They both need external energy sources to power a turbine, so they are very inefficient.

• They both have to be located directly on a coast to work effectively

• They both use a turbine with blades that spins a rotor attached to a shaft that spins a generator

What is geothermal energy, and what is one major disadvantage of it?

• Heat from earth's atmosphere, it creates a lot of pollution in the form of methane

• Heat from molten rock/lava located in volcanoes and geysers; it is only available to specific regions on earth

• Heat from electricity, it is very dangerous and hard to manage

• Heat from earth's oceans, it creates a lot of waste in aquatic environments

Of all fossil fuels, which is considered the "dirtiest"?

• Gas

• Oil

• They are all equally as dirty

• Coal
