Save Electricity
  Electricity is one of the best gifts of science. It is an essential resource
  for living life, especially for 21st-century people. Life without electricity
  would be impossible to imagine nowadays. Due to the huge demand for
  electricity worldwide, it has become hard to produce and provide it to
  everyone.
  The modern world without electricity is impossible now and it is needed in
  every sphere of life. We need it to lead a comfortable life. So the demand for
  power is directly correlated with population and economic growth. 
  Radio, television, cooler, heater, washing machine, air conditioners, etc all
  depend on electricity. Electricity has brought a great revolution in the field
  of medical science. Electricity has changed the way of farming. Without
  electricity, we cannot imagine industrial growth. Various means of
  transportation depend on electricity only.  Electricity boosts our modern
  life and helps in making it civilized.
  Electricity is generated by using coal, natural gas, nuclear energy, wind,
  solar energy, etc. Most of them are non-renewable resources that have limited
  reserves and it will take millions of years to replenish these reserves.
  There are many different ways in which we can save electricity. We can unplug
  computers, turning off televisions, fans, and lights when not in use. Solar
  panels can be planted to reduce the consumption of electricity. We can use
  more natural light. In the daytime instead of switching on lights and fans, we
  can keep our windows open to get natural light and air. Thus a small step will
  go a very long way in saving electricity.
  Electricity is the backbone of modern society. It serves mankind greatly. So
  we must stop the wastage of power. The world will lose its light if there is
  no electricity. Alternative sources of electricity should be explored to meet
  the gap between its demand and supply. We should realize the importance of
  electricity to save ourselves from the darkness. We should take every step to
  conserve sources of electricity for future generations.
