Energy Resources (non-renewable and renewable)

What are the two categories of energy sources? (Click two answers)

• Kinetic

• renewable

• thermal

• nonrenewable

Answer explanation

The two categories of energy sources are renewable and nonrenewable

What does the term renewable resource mean?

• A resource that in limited and will eventually run out.

• A resource that is easily replaced and will not run out.

• A resource that takes millions of years to form.

• A resource that is produced by burning fossil fuels.

Which are renewable energy resources. Click all that apply.

• coal

• wind

• nuclear

• solar

• biomass

Answer explanation

Another form of renewable energy is water (hydro energy) and geothermal energy (thermal energy from the earth's mantle)

Which is not a renewable energy source? (Click all that apply)

• hydro (water)

• oil

• biomass

• uranium

Answer explanation

Today the only substantial use for uranium is as fuel in nuclear reactors, mostly for electricity generation. Uranium-235 is the only naturally-occurring material which can sustain a fission chain reaction, releasing large amounts of energy.

What does the term nonrenewable resource mean?

• A resource that never runs out.

• A resource that is better for the environment.

• A resource that will eventually run out.

• A clean source of energy

What is a smaller collection of solar cell/panels called?

• A gaggle

• A matrix

• An array

• A module

Answer explanation

Crystalline silicon cells are made of silicon atoms connected to one another to form a crystal lattice. This lattice provides an organized structure that makes conversion of light into electricity more efficient.

This substance is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years.

• Uranium

• Coal

• Biomass

• Oil

• Hydropower

Answer explanation

Coal takes millions of years to formCoal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests.

Layers of dirt and rock covered the plants over millions of years. The resulting pressure and heat turned the plants into the substance we call coal.

What clean energy technology is shown in this picture?

• A hydroelectric dam

• A wind turbine

• A windmill

• A pinwheel

Answer explanation

The largest wind turbine in the world is in Hawaii, USAIt stands 20 stories tall and has blades the length of a football field!

What energy resource is shown in this picture?

• Nuclear energy

• oil

• solar panels

• biomass

Answer explanation

Nuclear energy provided 52% of America’s carbon-free electricity in 2020, making it the largest domestic source of clean energy.

Nuclear power plants do not emit greenhouse gases while generating electricity.

They produce power by boiling water to create steam that spins a turbine. The water is heated by a process called fission, which makes heat by splitting apart uranium atoms inside a nuclear reactor core.

True or false?

Fossil fuels are a form of renewable energy?

• True

• False
