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.

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.

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.

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.

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.

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.

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.

Forward-looking EU policies, with people and the economy at their heart, position Europe to become the world’s first climate-neutral continent by 2050.

Upcoming energy efficiency standards pose a significant challenge for smaller warehouses.

The world is off track in reaching the global goal to double energy efficiency by 2030 that was adopted at COP 28 in Dubai. A coalition of countries, businesses and organizations is urging world leaders at COP 29 in Baku to commit to actionable measures to unlock the energy efficiency investment that is crucial to meeting climate targets.

The Middle East, recognized for its extensive oil reserves and dry landscapes, is grappling with a series of interconnected challenges that are influencing its future: energy efficiency, water scarcity, and the necessity for decarbonization. As the world shifts towards a more sustainable and low-carbon future, nations in the Middle East are facing mounting pressure to tackle these issues and adapt to the evolving global environment.

Reducing a lighting system’s energy consumption requires more than just installing LED luminaires – effective control is essential. Installer looks at how advanced lighting controls can lead to more sustainable operations and significant long-term cost savings, while also enhancing occupant comfort, productivity and wellbeing.

LG Uplus said this test was carried out in collaboration with Infinera and Juniper Networks.
