Christian Ridley for Newsweek: Algal biofuels are in trouble. This alternative fuel source could help reduce overall carbon emissions without taking land from food production, like many crop-based biofuels do. But several major companies including Shell and ExxonMobil are seemingly abandoning their investments in this environmentally friendly fuel. So why has this promising technology failed to deliver, and what could be done to save it? Algae are photosynthetic organisms related to plants that grow in water and produce energy fromcarbon dioxide and sunlight. Single-celled microalgae can be used to produce large amounts of fat, which can be converted into biodiesel, the most common form of biofuel. There are many possible ingredients for making biofuels, from corn to used cooking oil. But algae are particularly interesting because they can be grown rapidly and produce large amounts of fuel relative to the resources used to grow them (high productivity). Cont'd...
Richard Martin for MIT Technology Review: At the giant Mohammed bin Rashid Al Maktoum Solar Park under construction near Dubai, a desalination facility goes into operation this month. Run by an array of solar panels and batteries, the system will produce about 13,200 gallons of drinking water a day for use on site. That’s insignificant compared with desalination plants elsewhere, but it’s a start toward answering a pressing question: can countries stop burning fossil fuels to supply fresh water? Hundreds of desalination plants are planned or under way worldwide because fresh water is increasingly precious. According to a report from the International Food Policy Research Institute, more than half the world’s population will be at risk of water shortages by 2050 if current trends continue. In drought-ridden California, a $1 billion plant at Carlsbad, north of San Diego, will produce 54 million gallons of fresh water a day. The giant Sorek plant in Israel can crank out more than 160 million gallons a day (see “Megascale Desalination” and “Desalination Out of Desperation”). But these plants are a devil’s bargain; they use power from plants that, in most cases, emit greenhouse gases, ultimately worsening the problem of drought. Saudi Arabia, for instance, uses around 300,000 barrels of oil every day to desalinate seawater, providing some 60 percent of its fresh water supply. That’s not sustainable. Finding a way to produce fresh water without burning fossil fuels is critical not just for the desert countries of the Middle East but for a growing number of places around the world. Cont'd...

PVinsights:Polysilicon price uptrend softens after the scheduling production retrieval of REC silicon
Polysilicon rally turns slow this week as the REC silicon production retrieval has alleviated buyer¡¦s speculation on supply shortage. Although polysilicon price in China continues on the rise, the scope is relatively incremental as compared to the past few weeks. In addition, since the non-American polysilicon suppliers have increased shipments to China for better spot prices, the supply level in overseas has become rather limited, leading the price in overseas to increase obviously this week. Nevertheless, the polysilicon has gradually losing its momentum amid the speculations on increasing supply level.

Joe Ryan & Brian Eckhouse for Bloomberg: For all the upbeat forecasts about the growth of solar power, this is a punishing year for the industry. And it won’t improve anytime soon. SunEdison Inc., the world’s biggest clean-energy company, is bankrupt. Yingli Green Energy Holding Co., once the top panel maker, warned it may be inching toward default. And SolarCity Corp., the largest U.S. rooftop installer, plunged as much as 27 percent Tuesday after scaling back its installation forecast for the third time in seven months. They’re not alone. A Bloomberg index of 20 major solar companies has slumped more than 30 percent this year. Soaring installations and growing global demand for clean energy is being trumped by investor concerns that the debt-fueled strategies employed by SunEdison, Yingli and SolarCity are endemic to the industry and dangerous for shareholders. “They call it the solarcoaster for a reason,” said Nancy Pfund, managing partner of DBL Partners and a SolarCity director. With so much happening, both positive and negative, “it’s been hard for investors to follow.” At a time when falling prices, renewed U.S. tax breaks and the Paris climate deal are fueling solar sales worldwide, solar shares are performing even worse than coal stocks.
