There are two sources of energy commercial and non- commercial. Non-commercial sources of energy are fire-wood, agricultural waste, and dried dung. These are non-commercial as they are found in nature. Non-commercial sources of energy like grass, hay, twings and small branches of tree, sun-dried cowdung cakes are generally renewable.
More than 60 percent of Indian households depend on these traditional sources of energy for meeting regular cooking and heating needs. The energy crisis can be overcome with the use of renewable sources of energy.
