The future of solar power is stuck in a lab. Here's how to get it out.
In our talk, Sivaram elaborated on why existing solar technology isn't good enough, why we need major advances, and what could prevent perovskites from actually panning out. The end result was a fascinating portrait of how technological innovation happens — and how potentially sweeping energy breakthroughs could fail to catch on.

How a Conservative Billionaire Is Moving Heaven and Earth to Become the Biggest Alternative Energy Giant in the Country
Philip Anschutz wants to turn his 500-square-mile cattle ranch into the world’s largest wind farm. The project would generate four times more electricity than the Hoover Dam, enough to power all of the households in Los Angeles and San Francisco. It would also make Anschutz the nation’s most unlikely environmental hero—if he can ever get the thing built.

Why the solar-plus-battery revolution may be closer than you think
In late April, Tesla Motors took a step toward upending home energy when it announced the Powerwall, a battery for homes that can provide backup power, and that was paired with higher capacity versions for businesses and even power companies. Within about a week of the announcement, Bloomberg reported, the company had already pulled in $800 million worth of orders, with the vast majority of revenue not for individual home batteries but rather for larger...

Chemists devise technology that could transform solar energy storage
Chemists have developed a major improvement to capture and retain energy from sunlight, where the stored energy can last dramatically longer than current solar technology allows -- up to several weeks, instead of the microseconds found in today's rooftop solar panels.

Solar: The First 1% Was the Hardest
Solar power now provides roughly 1% of the world’s electricity. It took 40 years to reach that milestone. But, as they say in tech, the first 1% is the hardest. You can see why in this chart below.

China is utterly and totally dominating solar panels
While China has long been a leader in making solar panels, it’s now become the largest market, by far, for solar panels. China has emerged as the world’s largest market for solar panels and in 2015 is expected to be home to a quarter of the planet’s new energy capacity from solar panels, according to a new report from GTM Research. China is rapidly adding as much power generation as possible, and solar is just one source of new energy generation in the country.

Solar power passes 1% global threshold
Last year 40 GW of new solar capacity was installed worldwide, compared to 38.4 GW in 2013, notes Solar Power Europe (SPE) in its Global Market Outlook 2015-2019. Cumulative capacity is now 178 GW. In terms of generation, this is equivalent to 33 coal-fired power stations of 1 GW, notes SPE. In Europe last year 7 GW was installed, which was less than in 2013. The UK was the fastest growing market, contributing 2.4 GW.

Record boost in new solar power continues massive industry growth
A record amount of solar power was added to the world’s grids in 2014, pushing total cumulative capacity to 100 times the level it was in 2000. Around 40GW of solar power was installed last year, meaning there is now a total of 178GW to meet world electricity demand, prompting renewable energy associations to claim that a tipping point has been reached that will allow rapid acceleration of the technology.
