Question

Why is energy efficiency important?

Answer 1

Our energy use has been increasing globally

Explanation:

Since our population (human population) grows, our energy use has been growing too. In order to control global carbon releases in the atmosphere, we need to find solutions.

One solution to fight against global climate change (as a result of increasing carbondioxide and other greenhouse gases caused by our thermal power plants, transportation systems, etc.) is to find more efficient devices (bulbs, heating systems, etc.). This will help us to control our total energy production and consumption even though population has been and will be growing.
