5 Floating Solar Farms Helping Power the World

Floating solar projects are popping up in all corners of the world, from Japan, the UK, Brazil, the U.S. and Australia.

There are a number of benefits to floating solar plants, aka "floatovoltaics." Compared to mounted panels, floating systems are naturally cooled by the bodies of water they sit on, therefore boosting power production efficiency. Many floating PV developers point out that the floatovoltaics shade the water, which reduces water evaporation and slow algae blooms.

“The efficiencies are what motivated us to look at this,” Rajesh Nellore, the chief executive of Infratech Industries, told the New York Times.

The Sydney-based company erected a floating solar system in Jamestown, South Australia that claims to generate 57 percent more energy than rooftop panels.

The plant floats on a wastewater facility in Jamestown and is the first part of a larger system that will cover five basins, the company says on its website. The system consists of raft supporting standard photovoltaic panels, which are specially coated to prevent corrosion, due to their close proximity to water.

Another plus of floating arrays is how it makes use of unused space. In the UK, a 6.3 megawatt floating solar project consisting of 23,000 solar panels sits on Walton-on-Thames' Queen Elizabeth II reservoir, an area that isn't used for any other purpose, The Guardian reported. The £6 million (about $8 million) project will help power local water treatment plants that provide clean drinking water to London and south-east England’s 10 million residents.

At roughly the size of eight soccer stadiums, the Thames Water floating solar array will briefly hold the title of world's largest floating solar facility before Japan’s mega-solar farm finishes in 2018, which will have a capacity of 13.7 megawatts. The New York Times noted that if everything goes as planned in the next two years, the 50,904 panels that will float atop the Yamakura Dam reservoir in Japan will generate an estimated 16,170 megawatt hours annually or enough electricity to power almost 5,000 homes.

The company behind Japan's massive solar plant, Kyocera TCL Solar, started construction in January this year and explained why floatovoltaics are ideal.

"With the decrease in tracts of land suitable for utility-scale solar power plants in Japan due to the rapid implementation of solar power, Kyocera TCL Solar has been developing floating solar power plants since 2014, which utilize Japan’s abundant water surfaces of reservoirs for agricultural and flood-control purposes," the company said in a press release.

Solar is also an increasingly attractive option for regions or countries that are going through drought. With Brazil's historic drought drying up its hydroelectric plants, the South American country is turning to solar power to diversify its energy mix to stave off a potential power crisis.

As EcoWatch reported last year, below-average rainfall in recent years have depleted the country's reservoirs, thus gutting the country's formerly plentiful supply of hydropower, which supplies more than three-quarters of Brazil's electricity, the U.S. Energy Information Administration states.

The nation announced last year it would commence pilot tests of a 350 megawatt floating solar farm located atop the Balbina hydroelectric plant in the Amazon.

“We are adding technological innovation, more transmission lines, diversifying our energy generation source, introducing solar energy in a more vigorous manner and combining solar energy with hydroelectric energy,” Mines and Energy Minister Eduardo Braga said last year.

According to PV Magazine, Brazil switched on the first 10 megawatt stage of its floating Ballina plant in March.

Another advantage of floating solar systems is that they can be hidden from public view, which is a factor that led the California nonprofit Sonoma Clean Power to pursue the technology, the New York Times reported.

“Sonoma County boasts some of the most beautiful rolling hills, and people don’t want to see them covered by solar panels,” Rebecca Simonson, a senior power analyst for the renewable energy developer, told the publication.

The Times reported that the company has signed purchasing agreements for floating solar arrays to be built on six treated water ponds in the county. The solar panels, Simonson said, would not be visible from the road.

Desperate Puerto Ricans Are Drinking Water From Hazardous Waste Sites

The ranking Democrat on the House Homeland Security Committee called for an investigation into the availability of potable water in Puerto Rico following reports Friday that residents are scrounging for water from hazardous waste sites.

After the U.S. Environmental Protection Agency (EPA) confirmed residents were trying to access water from three Superfund sites, and following a CNN story Friday featuring Puerto Ricans taking water from a fourth site, Rep. Bennie Thompson (D-MS) wrote a letter to acting DHS Secretary Elaine Duke asking if she knew about the situation and calling the reports "beyond disturbing."

Groups Slam Zinke's 'Backroom Deals' to Build Road Through Alaskan Wildlife Refuge

Ryan Zinke's Interior Department is working behind the scenes to build a controversial and long-contested road through the heart of Alaska's Izembek National Wildlife Refuge, documents show.

The refuge was established more than 30 years ago to conserve wetlands and habitats for migrating birds, brown bears and salmon and other wildlife. 300,000 of its 315,000 acres has been designated as Wilderness in 1980 under the Alaska National Interest Lands Conservation Act.

On World Food Day, Pope Francis Says Link Between Climate Change and Hunger Is Undeniable

By Andrew McMaster

Speaking at the United Nations Food and Agriculture Organization (FAO) on World Food Day, Pope Francis addressed the need for governments around the world to acknowledge that climate change and migration were leading to increases in world hunger.

Francis received a standing ovation after a stirring speech in which he said all three issues were interrelated and require immediate attention.

Why Are America's Bats Disappearing?

By John R. Platt

It's Friday evening in Pittsburgh, and the mosquitoes are out in force. One bites at my arm and I try to slap it away. Another takes the opportunity to land on my neck. I manage to shoo this one off before it tastes blood.

I'm at Carrie Furnaces, a massive historic ironworks on the banks of Pennsylvania's Monongahela River. Stories-tall rusting structures loom all around me, as do the occasional trees poking their way out of the ground. A tour guide, leading a group from the Society of Environmental Journalists conference, tells me the soil here is full of heavy metals and other pollutants from the factory, which operated for nearly a century before closing in 1982.

After a Half-Century, Tigers May Return to Kazakhstan

Wild tigers may be on their way back to Kazakhstan.

This news is surprising for a few reasons. First, most people associate tigers with the jungles of India or Sumatra, even the snowy slopes of eastern Russia—not the dry landscapes of Central Asia. But Iran, Turkey and Kazakhstan were once home to thriving populations of Caspian tigers. Unfortunately, sometime between the 1940s and '70s, this subspecies went extinct due to widespread trapping, hunting, poisoning and habitat degradation.

Second, Kazakhstan isn't a nation that often comes up in conversations about conservation. In fact, if Americans recognize the world's largest landlocked nation for anything, it's probably the movie Borat.

UN Urges World Leaders to Heed Climate Risk, Warns of More Severe Disasters

By Paul Brown

The hurricanes and wildfires that have severely damaged large areas of the U.S. in recent weeks have had no impact on President Donald Trump's determination to ignore the perils of climate change and support the coal industry.

In a deliberate denial of mainstream science, the Trump administration has issued a strategic four-year plan for the U.S. Environment Protection Agency that does not once mention "greenhouse gas emissions," "carbon dioxide" or "climate change" in its 48 pages.
