In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed
Solar energy begins with the sun. Solar panels are used to convert light from the sun, which is composed of particles of energy called 'photons', into electricity that can be used to power electrical loads.
Write down the benefits of using solar panels.
Nuclear energy originates from the splitting of uranium atoms – a process called fission.
This generates heat to produce steam, which is used by a turbine generator to generate electricity. Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.
Write down the advantages and disadvantages of Nuclear Energy.
A wind turbine, or alternatively referred to as a wind energy converter, is a device that converts the wind's kinetic energy into electrical energy.
Wind turbines are manufactured in a wide range of vertical and horizontal axis.
Write down the advantages and disadvantages of Wind turbines.
Hydrogen fuel is a zero-emission fuel burned with oxygen.
It can be used in fuel cells or internal combustion engines.
Name the advantages and disadvantages of Hydrogen fuel.
There are many different types of energy, which all fall into two primary forms – kinetic and potential.
Energy can transform from one type to another, but it can never be destroyed or created.
