An Efficient Solution
The article “An Efficient Solution” is about effective ways to conserve energy, how it effects the
world and how it effects our lives. Wasting less energy is the quickest, least expensive way to stem
carbon emissions. Energy conservation is the important part of energy policies.
Energy conservation is an important part of energy policies. To some people, “energy
efficiency” means less comfort. The concept of efficiency means that people get the same service using less
energy. The fastest way to reduce carbon emissions is to develop an efficiency strategy. We need more ways to
improve efficiency along the energy chain: primary energy such as oil, energy carriers such as electricity and
useful energy such as the heat in our ovens. New technologies, replace the present intensive use of energy and
materials. Insulating buildings more effectively, changing the industry process and driving aerodynamic cars would
reduce the demand for energy use.
Some household appliances conserve energy. A desktop computer generates less heat and is made of
recyclable materials. A dishwasher has a booster heater that raises water temperature to the required temperaturefor
dish washing, it also uses about a half the water required for manual washing. A convection oven can cut energy
use by 20% because the heat comes from the bottom and it blows the heat around to cook the food. A typical new
refrigerator uses one quarter the energy of a 1974 model.
In conclusion, the article “An Efficient Solution” is about improving the efficiency along the energy chain.
Insulating buildings more effectively decreases the demand for energy. Driving aerodynamic cars would reduce the
demand for gasoline. We have to find more...
