Energy in our lives

In the modern world, energy is needed for almost everything. It's almost impossible to imagine life without electric lights, without televisions, cell phones, laptop and desktop computers and more. Energy is consumed by almost every device that makes your life easier and more comfortable. It is also needed by lifesaving devices, such as heart defibrillators, nebulizers and an uncountable host of other things.
Energy is most often used in the context of energy resources, their development, consumption, depletion, and conservation. Since economic activities such as manufacturing and transportation can be energy intensive, energy efficiency, energy dependence, energy security and price are key concerns.
In short, without energy, modern life would be impossible. However, all of that energy comes at a cost. The environment pays dearly for our energy generation, as do the animals and plants that share this world with us. In addition, energy generation comes at a financial cost to you – constantly mounting electric bills are another hallmark of the "modern age." (source The Tesla Secret)
