Coal or coke is usually used for cooking. Electricity is not a very popular means for cooking in India because of the initial expenditure involved in buying an electric cooking range and the insufficient load of current available for domestic purposes. Kerosene oil stoves with blue flames are fast becoming popular with middle class people as they can easily be lighted and regulated and furthermore do not produce any smoke. It should however be noted that these stoves can be used only where medium heat is required and are useless as far as quick frying is concerned. Gas, otherwise ideal for cooking purposes because of its easy regulation and control, is not very popular in India because of its limited availability.
