Around 45 percent of households in India, mainly rural ones do not have electricity. Others, though electrified theoretically, remain without electricity due to poor or erratic supply. Even in relatively more advanced states such as Karnataka, 85% of the villages are connected to the grid and the poor are provided highly subsidized electricity, only about 31% of households in the electrified villages had been hooked up. Consequently, these households continue to rely on less efficient and polluting energy sources to the detriment of the environment, and to their own social and economic development.
