World's Largest Solar Park to Also Host World's Tallest Solar Tower

The Dubai government has awarded a $3.9 billion contract to construct the 700-megawatt fourth and final phase of the world-record-holding Mohammed bin Rashid Al Maktoum Solar Park.

The project also includes the construction of an 850-foot-tall solar tower that receives focused sunlight, the world's tallest such structure once complete.


The contract was awarded to a consortium of China's Shanghai Electric and Saudi Arabia's ACWA Power, who bid a Levelized Cost of Electricity of 7.3 U.S. cents per kilowatt hour—a record low price for concentrated solar power (CSP).

"Our focus on renewable energy generation has led to a drop in prices worldwide and has lowered the price of solar power bids in Europe and the Middle East. This was evident today when we received the lowest CSP project cost in the world," Saeed Mohammed Al Tayer, managing director and CEO of DEWA, said.

The facility will eventually produce 1,000 megawatts by 2020 and 5,000 megawatts by 2030, or enough power for 800,000 homes and the reduction of 6.5 million tonnes of carbon emissions annually.

CSPs use mirrors to concentrate the sun's rays to heat molten salt and produce superheated steam to drive a generator's turbines. Unlike traditional solar panels, CSPs can produce power long after the sun has set, and can store energy for up to 15 hours.

The massive solar park is part of the Dubai Clean Energy Strategy 2050, which aims to provide 7 percent of the emirate's total power output from clean energy sources by 2020, 25 percent by 2030 and 75 percent by 2050.

"This project is a game changer in our quest to decarbonize electricity generation by making available renewable energy at a price that competes with fossil fuel-generated electricity without subsidy not just when the sun is shining but at any time of the day and night," Paddy Padmanathan, president and CEO of ACWA Power, said in a news release.

Changing the Main Course of Climate Change

By Chloë Waterman

As the Trump administration's dangerous deregulatory agenda leads us closer to climate catastrophe, cities, counties and businesses are stepping up to address the crisis. Last month, Gov. Jerry Brown and former New York City Mayor Michael Bloomberg released their "Fulfilling America's Pledge" plan, laying out the top climate strategies for subnational governments and businesses, at the Global Climate Action Summit.

27 Injured, 300,000 Without Power as Leslie Becomes Strongest Storm to Hit Iberian Peninsula Since 1842

Leslie became the rare named Atlantic tropical system to hit Europe late Saturday when it rammed into Portugal as a post-tropical cyclone, injuring 27 and leaving more than 300,000 without power, The Associated Press reported Sunday.

Leslie had been downgraded from a Category One hurricane before making landfall, but it still lashed Portugal with hurricane-force winds. The seaside town of Figueira da Foz recorded wind speeds of 105 miles per hour.

These Newly Discovered Hummingbirds Can Survive High in the Andes—but Habitat Destruction Is Creeping Up on Them

Somehow the striking blue-throated hillstar, a hummingbird with an emerald-feathered head and sapphire splash across its neck, managed to elude us for a very long time. Scientists just recently discovered Oreotrochilus cyanolaemus, describing the species for the first time in The Auk: Ornithological Advances.

Top 10 Greenest Cities in America

San Diegans, pat yourselves on the back. Your city was ranked as 2018's "greenest city" in the U.S., beating out perennially crunchy San Franciscans by less than a point, according to WalletHub's calculations.

In a report released this week, the personal finance website compared the 100 most populated U.S. cities across 26 key "green" indicators, from greenhouse gas emissions per capita to share of electricity from renewable sources. Even the number of farmers markets and green job opportunities were considered.
