The advertisements calling for conserving of power, makes me laugh. As long as the sun continues to provide energy we will never run out of power. And we know that each atom has huge amount of energy, just that we just do not yet know how to harvest it. Necessity is the root cause of many discoveries and inventions. So let us create the necessity - please waste power.
And even if we consider having only limited power left, what is the purpose of saving power - to use it later to lead a comfy life. why not enjoy now itself? Live today. We are born to live, let us survive to die.
