I like this one in particular because the fossil fuel people said this was impossible.

Will California Reach Its 50% Clean Energy Goal? No Problem

But managing so much clean energy may be difficult. California will easily meet its goal of having half of its electricity come from clean energy by 2030, a group of energy entrepreneurs and the head of one of the state’s largest utilities agreed at Fortune’s Brainstorm E conference on Monday.

PG&E’s CEO Tony Earley said that the company had already reached a milestone earlier this year of getting 30% of its electricity from clean energy sources. Building on that landmark, PG&E already has clean energy projects lined up that will help it deliver half of its electricity from clean energy, like solar and wind, within less than 15 years, said Earley.

“We can get there,” he confidently predicted.

Earley noted that California’s definition of clean energy is particularly narrow. While some broader definitions of clean energy include big sources of carbon emissions-free power like nuclear power, hydroelectric, rooftop solar energy, and energy efficiency technology, California’s definition of clean energy only includes utility-scale solar and wind energy

I used to spend a lot of time posting articles here about Green Cars. They popped up on really divergent sites and sources. At one level, this made for honest reporting, because cars that weren’t very good got reported that way. But now there is a good source for reviewing all those green cars and here it is.

Tesla battery gigafactory opens as pace ramps up to ludicrous

If it’s built out to the full size in the original plans, the Tesla gigafactory outside Reno, Nevada, will cover 10 million square feet.

That’s the equivalent of more than 260 U.S. football fields, which would make it one of the largest buildings in the world.

Yesterday, Tesla Motors CEO Elon Musk officially opened the gigafactory building, which today is 14 percent of that size on a 3,000-acre site.

Owners of Tesla electric cars have been invited to an event to be held at the plant on Friday, but Musk spoke to the press yesterday from the site and declared it officially open.

The factory’s main mission is to produce lithium-ion cells at a far lower cost than any today, which will make the battery cost of the company’s upcoming Model 3 sedan low enough for a starting price of $35,000.

The Tesla Model 3 is supposed to go into production just 12 to 18 months from now, and ensuring the supply of cells and battery packs in sufficient volumes is what made the huge building necessary in the first place.

I have written so much about generation lately, that I forgot to say anything about storage. At least in awhile. The article below describes some progress being made on this front.

Inside the secret lab where Facebook tries to save your battery life

Deep inside Facebook’s very first data center, located in a sprawling facility in the hills of Prineville, OR, lies a series of about 60 server racks. Each one houses 32 smartphones, all of which are running a version of one of Facebook’s many mobile apps. The company calls this setup the Mobile Device Lab, and it’s designed to test Facebook’s software on older phones to discover whether any bit of a new code, no matter how minor, results in a dip in performance or poorer battery life. For those smartphone owners who tote around a two- or even three-year-old device — and users in developing countries purchasing lower-cost devices for the first time — the lab is the very reason Facebook is still a viable home screen staple.

Antoine Reversat, part of Facebook’s production engineering team, opens one of the racks for a group of reporters during its first Oregon data center tour in almost three years this week. Behind a large black metal door sit 32 iPhone 5C devices all in the process of either scrolling through the News Feed, testing various operations’ lag on battery consumption, or rebooting to resume an identical state before running yet another test. In each server row sits more than a dozen racks, some holding devices as old as the iPhone 4 and others housing newer Google Nexus 5s. In total, Facebook has almost 2,000 handsets used to tell developers when they’ve screwed something up, and whether that degradation is only noticeable on an older phone.

With Facebook serving more than 1.65 billion users around the world, taking into account every variation in device type, mobile operating system, and network condition has become an increasingly complex operation. Entire companies have built robust operations around testing mobile software in similar fashion, and some of those startups have been scooped up by big-name competitors. In 2014, Google bought San Francisco-based mobile app tester Appurify. Facebook’s engineers, on the other hand, figured the company could do the job itself, especially considering it had the computing power and server rack space at its expansive Oregon data center.
