Increased energy efficiency ultimately leads to lower costs
Answers
The statement is correct .If the energy level is lowered down then the amount of CO2 which is releasing in the atmosphere will reduce and this will impact the environment in the positive way.
Instead of using many large machines,only one can be made with high energy efficiency and the real life example is of Preem which is the largest fuel company in Sweden and they have reduced the heat exchangers from 4 to 1 which is a big thing.
Urbanization presents major challenges: congestion, sprawl, inefficiency, health hazards and high cost of living, just to name a few. But the choices we make for our cities can transform these challenges into opportunities: mobility, connectivity, economies of scale, healthier lifestyles and economic opportunity. Thus increased energy efficiency ultimately leads to lower costs.
