Energy efficiency is fast becoming a priority for a number of design and manufacturing industries. Taking energy from renewable sources, recycling existing energy, or using components that don’t need much juice are becoming popular options for organizations looking to cut energy costs in their production and other facilities. There has been significant research in a number of areas to achieve these goals that can use their own energy or don’t consume much to operate.

In the world of computer gaming, bragging rights are accorded to those who can boast of blazing-fast graphics cards, the most powerful processors, the highest-resolution monitors, and the coolest decorative lighting. They are not bestowed upon those crowing about the energy efficiency of their system. If they were, gaming computers worldwide might well be consuming billions of dollars less in electricity use annually, with no loss in performance.

Energy efficiency is the first step toward achieving sustainability in buildings and it is still the best way to both cut energy use and greenhouse gases (GHG) emissions at the same time. Singapore has committed to reduction in carbon emissions by 7% – 11% by 2020, compared to the current level. The efforts to achieve that goal is reflected through energy efficiency that this city-state undergoes across different sectors.

By the end of 2015, the waterway sector will cease oil lamp lighting operation for night navigation to switch to lighting automation technology.

While lithium-ion batteries are currently the gold standard for batteries and used in most of our electronics -- smartphones, computers, and more -- they have their short-comings.
