Renewable and Non Renewable Energy

Geothermal

Energy source that uses the heat below the Earth's surface to produce steam to spin a turbine. (Renewable)

Hydroelectric

Energy source that uses moving water to spin the turbine directly. (Renewable)

Solar

Energy source that uses the heat or light energy from the Sun to form electricity. (Renewable)

Wind

Energy source that uses moving air directly to spin a turbine. (Renewable)

Biomass

Energy source that uses energy from organic matter (living things) to produce steam to spin a turbine when burnt. (Renewable)

Fossil Fuels

Non-renewable energy source created by Earths pressure

Nuclear

Non-renewable energy source created by splitting uranium to produce heat. (For our class, we called it both renewable and non-renewable).

Coal

Solid fossil fuel (non-renewable) burned for power. Creates pollution.

Oil

Liquid fossil fuel (non-renewable) burned for power. Creates pollution

Natural Gas

Gas fossil fuel (non-renewable) burned for power. Creates pollution

Battery

Electrical energy can be stored in a ___.

Sun

The source of solar power

Atmosphere

Burning fossil fuels puts too much carbon dioxide into our _____ (the air surrounding our planet).

nonrenewable

Fuels that can NOT be reformed during a lifetime are said to be ___. They cannot be REPLACED

Water vapor

The only emission from a hydrogen fuel cell is ___ ___.

Generator

A turbine spins a ___ to produce electricity.

Photovoltaic

Energy from the sun is converted directly into electricity with a ___ cell.

Pollution

Electricity generated from renewable energy sources would be better for the planet because it produces little or no air ___ and will not run out.

Renewable

____ energy comes from sources that are infinite like the sun, wind, and water, or from sources that replenish themselves naturally like geothermal and biomass.

CAN BE REPLACED

Fossil fuels

Today, we primarily use ___ ___ to heat and power our homes and fuel our cars.

Earth

All of our trash and pollution must stay with us on board our "____".

Clean

We often call renewable energy technologies "___" or "green" because they produce few if any pollutants.

Wind

When the sun heats the air above the land, it rises and expands. Cooler air quickly moves in to fill the space left by the elevated air and this motion produces ___.

Conservation

Energy ___ means that you do not use energy when you do not have to.

Efficiency calculation

Useful energy out / total energy in

Global

We stop or slow ___ warming by changing the way we use energy and stop burning fossil fuels

Hybrid

___ cars use both gasoline and electric batteries. These cars have the best mileage rating of all cars.

Sustainable

Able to supply our needs today without harming future generation's needs; using a resource so that the resource is not depleted or permanently damaged

turbine

A device which blades are turned by a force (that of wind, water, or steam).

greenhouse gases

What is the name of the gases in the atmosphere that trap in heat?

water power

What is hydroelectricity / hydropower?

carbon dioxide

What is the greenhouse gas emitted when you burn fossil fuels?

renewable energy

What is the name for energy that will never run out - because it can be replaced

remains of dead animal and plant matter

What do fossil fuels come from?

motion or movement

Magnets + copper wire + ____ = electricity

solar cell

a photovoltaic cell -sun light changed to electricity

solar Panel

One way to create electricity from the sun is by focusing sunlight onto a pipe or tower using mirrors. The pipe gets so hot that it can boil water into steam. This type of energy is called ___.

Electric

___ cars get their energy from electric energy stored in batteries. When the battery runs out, it must be recharged by plugging the car into an electric power outlet.

Thermal

Solar energy can be converted to _____ energy and used to heat water and spaces.

Kinetic

A form of energy that results from an object's motion.

Potential

Stored energy that can become kinetic energy,

Horizontal, vertical

The two types of wind machines based on the direction of the rotating shaft.

Hydropower

Of the renewable energy's that generate electricity, this one is used the most. 71% of renewables.
