Abu Dhabi Desalination Plant to be Powered by Off-Grid Rooftop Solar
According to Renewable Energy World, the plant is the fifth desalination demonstration project from Masdar, which is currently running a pilot program to test renewably powered desalination plants in the United Arab Emirates. The group hopes to have a facility at commercial scale by 2020.
The project is expected to produce 30 cubic meters of water per day and will consume an estimated 2.8 kilowatt-hours per cubic meter of water, according to Marc Vergnet, head of Mascara. That's "significantly smaller" than the 3.6 kilowatt-hours per cubic meter of water that the other four desalination plants are projected to use, Water and Wastewater International Magazine said.
In addition to using less energy than the other four pilot projects, Mascara's will be the first to be off-grid and powered by solar. The trial is expected to begin in March and, if successful, Masdar said, the technology will be ideal for use in remote locations and especially on islands.
Desalination plants in the United Arab Emirates currently “are mainly thermal and aged," Dr. Alexander Ritschel, Masdar senior manager, told journalists on Monday. "There needs to be a transition to membrane-based desalination technology, which is more efficient than thermal processes installed sometimes up to 40 years ago.”
The five trial plants will run until 2017, with the goal of finding out “how the desalination plant of the future will operate,” Ritschel added.
Water stressed regions of the world, including the Gulf region, are rushing to develop energy-efficient desalination plants. There are an estimated 15,000–20,000 desalination plants around the world producing more than 20,000 cubic meters of water per day. Places as varied as Aruba, Chile and Algeria all use desalination.
Israel already supplies 40 percent of its drinking water from desalination. That number is projected to climb to 70 percent by 2050. Developers in Saudi Arabia are currently building the world’s first utility scale, solar-powered desalination plant. And last month, the largest desalination plant in the Western Hemisphere officially opened in Carlsbad, California, as the state struggles to deal with its prolonged drought.
Desalination is a contentious issue, though. Critics, citing marine impacts and its high cost, say desalination isn’t a good solution and can’t solve droughts. Masdar and its partners, however, are hoping to change that by improving existing technologies.

‘Companies Should Not Be Allowed to Use Hazardous Ingredients in Products People Use’: Michelle Pfeiffer Speaks Up for Safer Cosmetics
The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.
Michelle Pfeiffer wants to change that.
The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

Scientists at the United Nations' intergovernmental body focusing on biodiversity sounded alarms earlier this month with its report on the looming potential extinction of one million species — but few heard their calls, according to a German newspaper report.
The climate crisis is a major concern for American voters with nearly 40 percent reporting the issue will help determine how they cast their ballots in the upcoming 2020 presidential election, according to a report compiled by the Yale Program on Climate Change Communication.
Of more than 1,000 registered voters surveyed on global warming, climate and energy policies, as well as personal and collective action, 38 percent said that a candidate's position on climate change is "very important" when it comes to determining who will win their vote. Overall, democratic candidates are under more pressure to provide green solutions as part of their campaign promises with 64 percent of Democrat voters saying they prioritize the issue compared with just 34 percent of Independents and 12 percent of Republicans.
President Donald Trump has agreed to sign a $19.1 billion disaster relief bill that will help Americans still recovering from the flooding, hurricanes and wildfires that have devastated parts of the country in the past two years. Senate Republicans said they struck a deal with the president to approve the measure, despite the fact that it did not include the funding he wanted for the U.S.-Mexican border, CNN reported.
"The U.S. Senate has just approved a 19 Billion Dollar Disaster Relief Bill, with my total approval. Great!" the president tweeted Thursday.
"There was a lot of devastation throughout the state," Governor Mike Parson said at a Thursday morning press conference, as NPR reported. "We were very fortunate last night that we didn't have more injuries than what we had, and we didn't have more fatalities across the state. But three is too many."
