Energy Resources

Flashcards for key vocabulary related to Energy Resources.

Power

Measurement of how much energy is transferred per second.

Energy

The ability to do work or cause change.

Efficiency

The measure of how much of the energy supplied to a device is transferred into a useful form, rather than being wasted.

Renewable Energy

Energy from sources that can be replenished as we use them.

Non-renewable Energy

Energy from sources that are finite and will run out.

Fossil Fuels

Non-renewable energy sources formed from the remains of ancient plants and animals over millions of years (coal, gas, oil).

Greenhouse Gases

Gases that trap heat in the atmosphere.

Global Warming

The gradual increase in Earth's temperature due to the greenhouse effect.

Energy Resource

Stores of energy that we transfer into useful forms like electricity.

Efficiency Formula

Efficiency = useful output / total input.

Energy Use Calculation

Energy used = power x time.

Energy Bill Calculation

Cost = energy used x rate.

Carbon Dioxide

A pollutant produced by burning fossil fuels, increases the greenhouse effect.

Methane

A potent greenhouse gas emitted from fossil fuel use.

Sulphur Dioxide

A pollutant that causes acid rain, produced from fossil fuels.

Hydroelectric Energy

Energy generated by moving water, typically from dammed water releasing gravitational potential energy.

Solar Energy

Energy harnessed from sunlight, converted to electricity or thermal energy.

Wind Energy

Energy obtained from the movement of air, converted into electrical energy.

Geothermal Energy

Energy harnessed from the Earth's internal heat.

Biofuel

Fuel made from organic materials, such as plants.

Tidal Energy

Energy derived from the gravitational pull of the moon, harnessed from the movement of tides.

Wave Energy

Energy obtained from the movement of waves on the ocean.
