Other energy sources Flashcards
What is Nuclear Energy?
the energy released during nuclear fission or fusion, especially when used to generate electricity.
What are fossil fuels?
A fossil fuel is a hydrocarbon-containing material formed underground from the remains of dead plants and animals that humans extract and burn to release energy for use.
What are biofuels?
a fuel derived immediately from living matter.
What is Tidal Energy?
Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power.
What is Gravitational Energy?
Gravitational water vortex power plant is a green technology that generates electricity from alternative or renewable energy source.
Is Nuclear Energy good for the environment?
Yes, it doesn’t release carbon or sulphur dioxide.
Why is Nuclear Energy bad?
It is non renewable and releases hazardous, radioactive substances.
Why are fossil fuels good?
They are easy to get energy from and readily available.
Why are fossil fuels bad?
They are non renewable and release Carbon dioxide when burnt.
What are the positives of biofuels?
They are renewable and produce little to no carbon.
What are the negatives of Biofuels?
They use a lot of land and require lots of hard labour.
Why is Tidal and Grav energy good?
They are renewable and produces no emissions.
What does Water Energy do to the environment?
They cause visual pollution and damage habitats.
Why is Solar Energy beneficial?
It is renewable and there are no emissions.
Why is solar energy bad?
It is highly unreliable and solar cells are not efficient.
