There are large amounts of carbon in the form of coal as well as unconventional resources of natural gas and oil.
In the mid-1980s it decided to reduce dependence on imported fuel oil by converting power plants to natural gas.
This was a completely state-owned private company which held the natural gas monopoly and, from 1975, was in charge of creating the transmission network.
She identifies conversion of petrol and diesel vehicles to compressed natural gas as win-win options for consumers since they decrease pollution and save costs.
For example, for the natural gas strategy, we assume all kilns in all seven brickyards switch.
Total primary energy use is calculated as the simple sum of the standard coal equivalents of coal, oil, natural gas, and hydroelectricity.
As noted in the introduction, natural gas production has risen substantially only in recent years (mid-1980s).
Presently the best available coal and natural gas plants have efficiencies of about 45 per cent and 52 per cent respectively.
