Victoria’s Labor government has announced plans to expand the state’s energy reduction scheme – the Victorian Energy Efficiency Target (VEET) – as part of its effort to cut the state’s emissions and reduce electricity bills for households and business.

Scientists proved that potassium can serve as a cheap and abundant, highly efficient alternative to lithium in batteries with graphite anode.

The new Burton Brewery energy centre opened by Molson Coors has delivered £750,000 of cost savings in its first year of operation.

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.

The remote jungle village of La Mancalona on the Yucatan peninsula of Mexico has gone from a place where clean water was scarce, bottled water expensive and soda much cheaper to a place where they have a reliable source of purified water and a profitable business in just two years.

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.

Eight of the world's 10 most polluting countries are expected to double their collective renewable energy capacity in the next 15 years, a new study from the World Resources Institute (WRI) has found.

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.

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.

A new solar fuel generation system, or artificial leaf, safely creates fuel from sunlight and water with record-setting efficiency and stability.

Speeding off from Darwin on Oct. 18, 42 futuristic solar cars from more than two dozen countries competed in the 2015 World Solar Challenge.

The Friends School of Portland in Maine is the first Passive House school building in the state, and only the third in the country.

Water and waste water treatment typically account for 35 percent of a municipality’s energy budget, which would mean big savings for local governments that can make the facilities energy neutral.

The U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) today announced up to $30 million in funding for a new program focused on improving the energy efficiency of commercial and residential buildings.

Newly installed heating and hot water systems are now required to display an energy efficiency label rating under new EU legislation.

Delhi is getting its first hydro-power plant, but it’s not harvesting the energy of running water in the traditional hydroelectric model, as this new system uses falling water from a treated sewage effluent pipe to spin its turbine.

GreenWood Forest Park in North Wales is set to save over £1m on its energy bills thanks to a newly installed ground-mounted solar array system.

INTENSE aims at transferring intelligent energy saving measures for municipal housing from “old” EU Member States to “new” Member States and Accession countries in Central and Eastern Europe.

The Federal Aviation Administration (FAA) selected eight manufacturers to receive $100 million in contracts to develop and demonstrate technologies that reduce fuel consumption, emissions, and noise, under the second phase of its Continuous Lower Energy, Emissions, and Noise (CLEEN II) program.

Japan’s Mitsui OSK Lines (MOL) has started demonstration tests of a new windshield for containerships, potentially reducing wind resistance, saving fuel and lowering carbon dioxide emissions.
