When we say that electricity is all around us we mean that electricity is stored in may forms and therefore can be generated through those means.The sparky observation when one walks across a carpet or touches a metal knob is due to the imbalance of electric charges within or on the surface of those materials; that is what we call Static electricity. The charges remain on those objects or surfaces until the current discharges by moving away. The Charges are is usually created whenever the there is a separation between surfaces that were in contact and at least one surface is highly resistant to electrical.
