Climeworks was founded in 2009 by Christoph Gebald and Jan Wurzbacher. These two young minds knew that CO₂ was harmful to the atmosphere and in turn the world needed to find a way to remove it from the air, or as much as they could.

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.

Recently, SolarCity announced it will begin manufacturing the “world’s most efficient solar panels” at its factory in Buffalo, New York, starting in 2016. It claims it has designed a panel that converts 22.1% of sunlight into electricity.

Sweden’s iconic ICEHOTEL has announced plans for a permanent solar-powered addition that will offer a sub-zero ice experience year round.

Every year, the information technology sector spends almost $7 billion on electricity costs, and much of that money goes to cooling computer processing units (CPUs) in data centers. At the Energy Department’s Sandia National Laboratories, researchers have developed an innovative new air-cooling technology - the Sandia Cooler - that improves the way heat is transferred in computers and microelectronics, significantly reducing the energy needed to cool CPUs in data centers.

Electrical and computer engineers at North Carolina State University have developed a new technique for creating less-expensive, low-power embedded systems -- the computing devices found in everything from thermostats to automobiles.

A Florida State University engineering professor has developed a new highly efficient and low cost light emitting diode that could help spur more widespread adoption of the technology.

On November 5, 2015, in Hanoi, Vietnam Chamber of Commerce and Industry (VCCI) in cooperation with the Embassy of Iceland held a seminar on "The future of clean energy."

On November 6, 2015, at Electricity Hotel, General Department of Energy - Ministry of Industry and Trade organized "Training conference in cost estimation, settlement of full payment and financial compliance audit as specified by the Law on Economical and Efficient Use of Energy".

On November 3rd, 2015, in Washington, DC, the Embassy of Vietnam in the United States in collaboration with the Business Association of Overseas Vietnamese - US foreign affiliates (BAOOVUS) organized a seminar "Vietnam-US Business Partnership for Energy Development".

Expansion of renewable energy sources is one of the important dimensions for promoting the development of the electricity sector to help the electricity sector meet the demand of 7-10% annual growth until 2030.

Right now, the vast majority of the wind power generated on the planet comes from land-based turbines.

Canary Wharf Group has carried out a major lighting upgrade on its property portfolio, saving more than £400,000 and over 1,951 tons of carbon annually.

In the implementation of the Law on economical and efficient use of energy, Directive No.171/CT-TTg dated November 26, 2011 by the Prime Minister, Directive No.06/2011/CT-UBND and Green Energy Programme of Ho Chi Minh City in 2015 in the phase of 2011-2015, Ho Chi Minh City continues to perform its leading role in the implementation of guidelines on power saving.

German households and industry made great strides last year to use energy more efficiently, according to energy market research group AG Energiebilanzen (AGEB).

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.
