New Silicon Nanowires Can Really Take the Heat

A Berkeley Lab-led research team has demonstrated an ultrathin silicon nanowire that conducts heat 150% more efficiently than conventional materials used in advanced chip technologies. The device could enable smaller, faster, energy-efficient microelectronics.

How Venice, Italy Can Cut Carbon Emissions from Social Housing

Research using software developed at Berkeley Lab recently pinpointed actions that could help the historic canal city of Venice, Italy slash energy use and reduce carbon dioxide emissions.

Skyrmions on the Rise – New 2D Material Advances Low-Power Computing

A team co-led by Berkeley Lab has discovered a new ultrathin material with exotic magnetic features called skyrmions. The new material could enable the next generation of tiny, fast, energy-efficient electronic devices.

New Smart-Roof Coating Enables Year-Round Energy Savings

Scientists have developed an all-season smart-roof coating that keeps homes warm during the winter and cool during the summer – without consuming natural gas or electricity. Research findings point to a groundbreaking technology that outperforms commercial cool-roof systems in energy savings.

A ‘BETTER’ Way Forward for Low-Cost, Accessible Retrofits

Building operations account for a whopping 35% of U.S. carbon dioxide emissions. A free online tool developed by Berkeley Lab with support from the U.S. Department of Energy’s (DOE) Building Technologies Office (BTO) — the Building Efficiency Targeting Tool for Energy Retrofits (BETTER) — is helping to bring that number down by virtually evaluating buildings for immediate no- and low-cost energy efficiency upgrades.

LED Material Shines Under Strain

With a simple stretch, a thin semiconductor material can achieve near 100% light-emission efficiency at all brightness levels. The discovery, reported by scientists at Berkeley Lab and UC Berkeley in the journal Science, has implications for energy-efficient mobile devices and lighting applications.

How Managing Building Energy Demand Can Aid the Clean Energy Transition

Since buildings consume 75% of electricity in the U.S., they offer great potential for saving energy and reducing the demands on our rapidly changing electric grid. But how much, where, and through which strategies could better management of building energy use actually impact the electricity system?

Pioneering Framework Could Reduce Energy Demand in Buildings

Heating and cooling buildings is a large part of global energy demand and a significant source of CO2 and greenhouse gas emissions, and in the coming decades the energy demand for heating and cooling – also known as thermal energy – is expected to grow considerably. Scientists and engineers have made many advances in lowering

Berkeley Lab Building Efficiency Campaign Drives $95M in Annual Energy Savings

One hundred and four U.S. companies, schools, governments, and institutions are taking their building energy savings to a new level with the Department of Energy’s Smart Energy Analytics Campaign, a four-year initiative funded through the Building Technologies Office and facilitated by Berkeley Lab.

Keeping Cool Efficiently During Heat Waves

Heat waves are becoming a more regular occurrence across the country. Iain Walker, Leader of the Residential Building Systems Group at Berkeley Lab, has suggestions on efficient use of your air conditioner.
