Meredith Fowlie Residential solar: How should distributed generation be distributed?

Growth in the residential solar market continues apace. In the United States, residential solar PV installations last quarter were up 11 percent over the previous quarter:

The figure  illustrates this impressive growth rate (in dark blue). However, this is growth on a very small base. By my crude calculations, less than … More >

Santiago Miret Transportation: Land of Cleantech Opportunity

Over 95% of the 1 billion cars in the world are parked at any given time and 95% of the energy consumed by a car is spent on moving the vehicle forward, not the person it is transporting. The many shortcomings of the modern transportation that have left tremendous opportunities … More >

Meredith Fowlie One university’s attempt to reduce energy waste at work

If you work outside your home, chances are you don’t pay (directly) for the energy you use at work. At my place of work, the UC Berkeley campus, most employees never see – let alone pay – their energy bills.

Of course, there are plenty of pro-social reasons to be conscientious … More >

Catherine Wolfram A common energy-saving device I’ve never seen in the U.S.

I tend to think of the U.S. as ahead of most of the rest of the world when it comes to energy efficiency. Maybe not in the Germany or Japan league, but at least above the median. After all, our utilities are spending billions of dollars per year encouraging energy efficiency and … More >

Santiago Miret How Bit Met Watt

With the miniaturization of electronics, the world’s computing capabilities exploded, while the energy required to produce bits of data continued to drop. The world was creating more and bits of data, which required less and less watts to operate. As the computing devices became smaller, we went from room-sized computer … More >

Dan Farber Lightbulb wars: the saga continues

Republicans have won a largely symbolic victory for an obsolete technology. Among the sleeper provisions of the new budget deal is a ban on enforcing federal lightbulb standards.  This is a great example of symbolic politics — it makes Tea Party Republicans happy, has limited practical effect, and makes little policy … More >

Catherine Wolfram How California’s K-12 schools can teach us about energy efficiency

California has long been a leading indicator of national energy-efficiency trends. The state passed minimum efficiency standards for refrigerators in 1976, 11 years before the federal government adopted similar standards. And, the recent Corporate Average Fuel Economy standards are based on legislation passed in California several years earlier.

The state is about … More >

Maximilian Auffhammer Nest(ing): A home-energy home run for Mother Earth

Happy Earth Day everyone! I briefly contemplated a doom and gloom post about the state of the global climate and lack of regulation. But let’s focus on what does work, albeit at a much smaller scale, instead of what doesn’t work.

Team Auffhammer has invested a lot of money in energy … More >

Elizabeth Bailey From big energy consumption (E) to lower energy consumption (e)

Very little shocks me anymore. But I was shocked – SHOCKED! – to discover that one space in our house which takes up only about 5% of the floor space draws more than 20% of the KWH our house consumes in a day.

Can you guess which room this is? It … More >
