Elon Musk's New Solar Project: 'It’s Not a Thing on the Roof. It is the Roof'
Tesla and SolarCity could change the roofing industrySolarCity Twitter
As Electrek reported, during a conference call with investors Tuesday, Musk and SolarCity CEO Lyndon Rive said they were working on creating a roof made entirely of solar panels—solar shingles, if you will. Instead of tacking on solar panels onto an existing roof, the whole roof itself will be integrated with photovoltaic material.
"I think this is really a fundamental part of achieving differentiated product strategy, where you have a beautiful roof," Musk said. "It's not a thing on the roof. It is the roof."
Rive confirmed the project. According to Electrek, "Rive added that there are 5 million new roofs installed every year in the U.S. and if your roof is about to need to be replaced, you don't want to invest in solar panels to install on it since you are about to take it down, but if the solar panels are the roof and you need to redo it anyway, there's no reason not to go with a power-generating roof."
Roofs certainly don't last forever. As U.S. News explained, depending on the material, roofs can last more than 50 years but homeowners with roofs made of fiber cement shingles or asphalt shingle/composition roofs can expect a lifespan of 20-25 years. Inclement weather—snow, hail and hurricanes—can cut a roof's lifespan even shorter.
Asphalt roofs—which are by far the most common in the U.S.—also happen to create about 11 million tons of waste each year. Though inexpensive, asphalt shingles are also a petroleum-based product which carries major environmental impacts. So if a homeowner needed to re-shingle the roof anyway, why not go with shingles that could double as an electricity generator instead and might be better for the environment?
Musk, who is the chairman and largest shareholder of Tesla and SolarCity, said there's a "huge" market for roofs at the end of their lifespan.
He also said, according to Bloomberg, "If you need to replace your roof in the next five years, you're not going to get solar. What if your roof looks better and last longer?"
Musk and Rive did not provide exact details on the solar roof, but they are not inventing something brand new if they are proposing to produce solar shingles. Dow's Powerhouse was the biggest name to forge this path around 2009, but the technology was possibly too expensive and perhaps impractical to take off. The company decided to stop selling this product just this past June.
Electrek deduced that the other new Tesla/SolarCity solar product will be for existing roofs. The two products are expected be unveiled by the end of this year.
Meanwhile, Tesla's $2.6 billion stock offer for SolarCity awaits shareholder approval. In announcing its decision to combine with SolarCity, Tesla said it has a vision of "creating the world's only vertically integrated sustainable energy company."

A recent intensification in protests against Williams Partners' planned Atlantic Sunrise pipeline in Pennsylvania prompted a state senator to propose legislation aimed at limiting demonstrations.
Last month, Pennsylvania Sen. Scott Martin (R-Norman) announced his intention to introduce legislation that would pass the costs of law enforcement responding to protests onto the demonstrators. Martin also helped introduce a different bill that would criminalize protests at natural gas facilities.
The so-called "first and last mile" problem is one of the biggest hurdles with public transportation. How do you encourage more people to take Earth-friendlier commutes when their homes are miles away from the train or bus station?
One solution, as this Estonian electric scooter company proposes, is to simply take your commute with you—literally. Tallinn-based Stigo has developed a compact e-scooter that folds to the size of a rolling suitcase in about two seconds.
[Editor's note: I'm still in shock after hearing the news that Lucia Grenna passed away in her sleep last week. When we first met in April of 2014 at a Copenhagen hotel, I was immediately taken by here powerful presence. We spent the next couple days participating in a Sustainia climate change event where Lucia presented her audacious plans to connect people to the climate issue. I had the chance to partner with Lucia on several other projects throughout the years and work with her incredible Connect4Climate team. I was always in awe of her ability to "make the impossible possible." Her spirit will live on forever. — Stefanie Spear]
It is with a heavy heart that Connect4Climate announces the passing of its founder and leading light, Lucia Grenna. Lucia passed peacefully in her sleep on June 15, well before her time. We remember her for her leadership and extraordinary ability to motivate people to take on some of the greatest challenges of our time, not least climate change.

Neil deGrasse Tyson has inspired millions of people to care about science and imagine themselves as participants in the scientific process. What a hopeful sign it is to see young girls wearing t-shirts emblazoned with the words, "Forget princess, I want to be an astrophysicist."
As Trevor Noah noted during The Daily Show episode last night (starts at 2:25), the real reason Trump has these rallies is to "get back in front of his loyal crowds and feed of their energy." Noah believes that "Trump supporters are so on board with their dude he can say anything and they'll come along for the ride."

Two years ago—long before coal became one of the most dominant and controversial symbols of the 2016 presidential election—Bloomberg Philanthropies approached production company RadicalMedia with the idea of creating a documentary exploring the U.S. coal mining industry. Last spring, they brought on Emmy-nominated director Michael Bonfiglio, tasked with forging a compelling story out of the multitudes of facts, statistics and narratives underlying the declining industry.
