I am informed by ESB National Grid that the distribution of electricity generation by fuel source in percentage terms over the past five years is as set out in the following table.
| Year | Coal | Heavy Fuel Oil | Light Fuel Oil | Gas | Native (peat) | Hydro | IPP1 | Small-Scale Generation including Wind | Total |
| 2004 | 25.7 | 12.2 | 0.2 | 25.1 | 4.8 | 2.5 | 19.7 | 3.4 | 93.62 |
| 2003 | 25.4 | 9.7 | 0.3 | 29.8 | 8.2 | 2.3 | 21.7 | 2.7 | 100 |
| 2002 | 27.9 | 15.0 | 0.2 | 32.6 | 8.4 | 3.6 | 9.7 | 2.6 | 100 |
| 2001 | 28.7 | 20.9 | 0.3 | 36.8 | 8.9 | 2.3 | — | 2.2 | 100 |
| 2000 | 30.0 | 18.9 | 0.3 | 37.6 | 7.5 | 3.5 | — | 2.1 | 100 |

| 1IPP refers to independent power producers who use gas as their energy source. | |||||||||
| 2The balance for 2004 is accounted for by electricity brought into the country via the North/South |
The percentage figures for 1990 provided by ESB National Grid are as follows:
| Year | Coal | Heavy Fuel Oil | Light Fuel Oil | Gas | Native (peat) | Hydro | IPP | Small-Scale Generation | Total |
| 1990 | 41.7 | 10.0 | — | 27.4 | 16.0 | 4.9 | — | — | 100 |
ESB National Grid points out that in 1990 ESB was the only generator on the system and therefore no figures are provided for independent power producers and small-scale generation. In addition, I am informed that light fuel oil was unavailable as a fuel source in 1990.
