IEA defines energy intensity as the amount of primary energy used to produce a given amount of economic output. It is the key global indicator to track energy efficiency- which is technically the rate of change in primary energy intensity.

Owensboro Health Regional Hospital has earned its fifth Energy Star certification, with officials saying OH has saved more than $4.5 million over the last decade due to energy efficiency practices. According to a release from OH, participating healthcare facilities strive to obtain the Energy Star recognition threshold of 75 or higher. Owensboro Health Regional Hospital scored 77, meaning its Energy Use Index (EUI) is better than 77% of hospitals in the country. Only two other hospitals in Kentucky have been Energy Star recipients longer than Owensboro Health.

As cooler weather approaches, Southern California Gas Company (SoCalGas) shares energy-saving tips and tools to help customers prepare their homes. 

As climate change laws like Boston’s BERDO and New York City’s Local Law 97 reshape commercial real estate, landlords and tenants face new challenges. These regulations aim for net-zero emissions by 2050, impacting energy efficiency and emissions reduction in buildings. Lease negotiations must address costs, responsibilities, and compliance to avoid penalties and ensure sustainability.

British Columbians are seeing first-hand the costly impacts of more frequent and intense, extreme weather events fuelled by climate change.

Engineers at Vodafone are working with AMD to design mobile base stations capable of supporting AI workloads in addition to traditional network operations while using less power.

Governor Kathy Hochul announced New York is the first state to offer retail rebates for low-and moderate-income residents to purchase energy-efficient appliances.

Speira’s new “transparent” melting furnace delivers more capacity, more recycling, precise insights and data collection in all process steps with 15 percent less energy.

Researchers at Rice University have found a new way to improve a key element of thermophotovoltaic (TPV) systems, which convert heat into electricity via light. Using an unconventional approach inspired by quantum physics, Rice engineer Gururaj Naik and his team designed a thermal emitter that can deliver high efficiencies within practical design parameters.

I had the opportunity to visit a children’s health center located about 300 km away from Astana, on the shores of a beautiful lake. The center, which celebrated its 60th anniversary this year, has introduced green technologies, such as renewable energy and energy efficiency systems. It was inspiring to witness how such initiatives can tangibly improve sustainability while reducing environmental impacts.

Birmingham-based craft beer maker Attic Brew Co is one of more than 2,000 businesses being backed by a multi-million-pound scheme helping firms cut their energy usage and fuel bills.

A final push would allow the Biden administration to reach its pollution reduction goals.

While utility costs are inevitable, there are strategies to make food and beverage plants more efficient and save money in the long run.

Japan and Vietnam have deepened their cooperation based on Joint Crediting Mechanism (JCM) and issued carbon credits for nine new projects by the end of October.

The atoms of amorphous solids like glass have no ordered structure; they arrange themselves randomly, like scattered grains of sand on a beach. Normally, making materials amorphous—a process known as amorphization—requires considerable amounts of energy.

Conversion to biogas could reduce emissions and save more than £400 million a year in fuel costs.

Shell Malaysia has unveiled a significant plan to accelerate its transition towards net-zero emissions by 2050, with a focus on installing solar panels across the rooftops of its more than 600 retail sites. The solar installation will have a total capacity of 20 MWp, with plans for all sites to switch to solar power by next year.

The industrial sector in the Kingdom consumes approximately 48% of the country's primary energy, with "energy-intensive" industries such as petrochemicals, cement, steel, and aluminium accounting for around 70% of this consumption.

Cutting the energy used while firing the bricks means big savings at scale.

A new commentary, published by members of the Energy Demand Changes Induced by Technological and Social Innovations (EDITS) network, coordinated by IIASA, highlights that switching the focus from how energy is supplied to how energy is consumed can be a more effective approach to reducing carbon emissions with the added benefit of improving wellbeing for all.
