- Useful
Energy
- Useful Energy- Transferred
where and in the form we
want
- Wasted Energy- Not
useful energy
- All eventually transferred to
surroundings, making it
harder to use
- Useful Energy- Transferred
where and in the form we
want
- Energy and
Efficiency
- Efficiency= (Useful energy/ Total
energy supplied) x100
- Can't be more than
100% efficient
- Represented in Sankey diagram
- Efficiency= (Useful energy/ Total
energy supplied) x100
- Using
Energy
- Forms of
Energy

- Conservation of
Energy
- Energy cannot be
created or
destroyed
- Total energy
always the same
- Energy cannot be
created or
