New Berkeley Lab study finds lower greenhouse gas emissions on per-mile basis for driverless cars deployed as taxis.

Imagine a fleet of driverless taxis roaming your city, ready to pick you up and take you to your destination at a moment’s notice. While this may seem fantastical, it may be only a matter of time before it becomes reality. And according to a new study from Lawrence Berkeley National Laboratory (Berkeley Lab), such a system would both be cost-effective and greatly reduce per-... Read More

The average total cost of saving electricity through utility efficiency programs
April 28, 2015

What does it cost to save electricity?

Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) have conducted the most comprehensive study yet of the full cost of saving electricity by U.S. utility efficiency programs and now have an answer: 4.6 cents. That's the average total cost of saving a kilowatt-hour in 20 states from 2009 to 2013, according to a Berkeley Lab report titled,... Read More

April 14, 2015
Standards body approves Berkeley Lab’s method to mimic natural soiling of roofing materials.

Cool roofs can help keep buildings cool, thus lowering the building’s energy use, while also mitigating the urban heat island effect by reflecting sunlight away from buildings and cities. But as cool roofs age and get soiled, how much of their reflectance do they lose?

A collaboration led by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) has established a method to simulate... Read More

The modern grid
November 25, 2014

An excerpt from a U.S. Department of Energy blog:

"...dramatic changes are occurring in our nation’s energy mix, many of which demand a more technologically advanced electric grid. Increasing use of renewable energy sources, risks of cyber and physical attacks, and aging infrastructure create uncertainty of the current grid’s long-term ability to provide the services demanded of it. These include distributing and storing clean energy, enabling greater consumer choice and increasing... Read More

Researchers in the Environmental Energy Technologies Division of Lawrence Berkeley National Laboratory have released a new report titled “Exploring California PV Home Premiums.”

Although photovoltaic (PV) penetration in the United States is increasing rapidly, properly valuing homes with PV systems remains a barrier to PV deployment. Previous studies show that PV homes command sales price premiums. Still, some appraisers and other home valuers assign no value to a home’s PV system,... Read More
