World's Largest Solar Project Would Generate Electricity 24 Hours a Day, Power 1 Million U.S. Homes

The race to build the world's largest solar power plant is heating up. California-based energy company SolarReserve announced plans for a massive concentrated solar power (CSP) plant in Nevada that claims to be the largest of its kind once built.

The 110 MW Crescent Dunes Solar Energy Plant near Tonopah, Nevada was the first utility-scale facility in the world to feature advanced molten salt power tower technology. The developer wants to build 10 more of these at an undisclosed location in Nevada. SolarReserve

SolarReserve CEO Kevin Smith told the Las Vegas Review-Journal that the $5 billion endeavor would generate between 1,500 and 2,000 megawatts of power, enough to power about 1 million homes. That amount of power is as much as a nuclear power plant, or the 2,000-megawatt Hoover Dam and far bigger than any other existing solar facility on Earth, the Review-Journal pointed out.

"It's a big project," Smith told the publication. "It's an ambitious project."

SolarReserve's Sandstone project involves at least 100,000 mirrored heliostats that capture the sun's rays and concentrates it onto 10 towers equipped with a molten salt energy storage system. The molten salt, heated to more than 1,000 degrees, then boils water and creates a steam turbine that can drive generators 24/7.

Compared to photovoltaic arrays, the appeal of CSP systems is that solar power can be used after sunset.

"It's really the ability to provide renewable energy that's available on demand 24 hours a day," Smith told NPR.

SolarReserve already operates a CSP plant near Tonopah, a revolutionary 110-megawatt Crescent Dunes Solar Energy Plant that's now powering Nevada homes. The company says on its website that this "completely emission free" CSP plant runs without the requirement for natural gas or oil back up.

"Energy storage provides a firm, reliable electricity product on-demand, day and night," SolarReserve says, adding that the plant "helps meet growing demand for clean, renewable energy sources."

Smith told the Review-Journal that Sandstone construction probably won't begin for another two or three years. Once construction begins, Smith estimated the project should create about 3,000 jobs for about seven years.

He said the company will also have to build a new transmission infrastructure to carry the energy to market, and the generated power will likely will be "exported to the California market."

SolarReserve is narrowing down project sites for its 6,500-hectare project. Smith said two potential sites on federal land in Nye County have been shortlisted. However, as NPR reported, environmentalists such as Solar Done Right's Janine Blaeloch are concerned about the environmental impact of such a project.

"It transforms habitats and public lands into permanent industrial zones," she told the radio station.

Trump Administration Offers 77 Million Acres in Gulf of Mexico to Oil Industry

The Trump administration is holding the biggest offshore oil and gas lease auction in U.S. history Wednesday, offering all 77 million acres of unleased, available federal waters in the Gulf of Mexico.

The sale comes as administration officials seek to rescind drilling safety rules approved after the BP Deepwater Horizon disaster, reduce royalties paid by oil companies, and expand offshore drilling into every ocean in the country.

Pruitt to Restrict Use of Scientific Data in EPA Policymaking

In the coming weeks, U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt is expected to announce a proposal that would limit the type of scientific studies and data the agency can use in crafting public health and environmental regulations.

The planned policy shift, first reported by E&E News, would require the EPA to only use scientific findings whose data and methodologies are made public and can be replicated.

Notorious Toothfish Poacher Arrested by Liberian Coast Guard, Assisted by Sea Shepherd

A notorious Antarctic and Patagonian toothfish poaching vessel, famous for plundering the Antarctic, was arrested on March 13 in waters belonging to the West African state of Liberia by the Liberian Coast Guard, with assistance from the marine conservation group Sea Shepherd.

The F/V Hai Lung, known to the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) by its previous name "Kily," was transiting through Liberian waters when it was boarded and inspected by a Liberian Coast Guard team working alongside Sea Shepherd crew on board Sea Shepherd's patrol vessel M/Y Sam Simon.

EU Approves Controversial Bayer-Monsanto Merger

The European Union approved Bayer's takeover of Monsanto, a major hurdle in the $66 billion merger that would create the world's largest integrated seed and pesticide conglomerate.

The European Commission said the German chemical-maker's takeover of the St. Louis-based agribusiness giant is "conditional on an extensive remedy package, which addresses the parties' overlaps in seeds, pesticides and digital agriculture."

Ocean Plastic Projected to Triple Within Seven Years

If we don't act now, plastic pollution in the world's oceans is projected to increase three-fold within seven years, according to a startling new report.

The Future of the Sea report, released Wednesday for the UK government, found that human beings across the globe produce more than 300 million metric tons of plastic per year. Unfortunately, a lot of that material ends up in our waters, with the total amount of plastic debris in the sea predicted to increase from 50 million metric tons in 2015 to 150 million metric tons by 2025.
