Renewable energy derives from the elements earth, air fire and water, as detailed here.
The most commonly used options are shown with a darker border below.
Elemental renewable technologies convert the energy from these elements directly to electricity or heat or both (CHP):
| Source | Heat | CHP | Power |
E
A | Geothermal | 
| 
|
|
R
T
H | Ground heat | 
|
|
|
A
I | Air heat | 
|
|
|
R | Wind |
|
| 
|
F I R E | Sun | 
| 
| 
|
| Hydro (rivers) |
|

T
E | Tidal stream |
|
| 
|
R | Water heat | 
|
| 
|
| Waves |
