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.
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.

- Research shows that 16 weeks of a vegan diet can boost the gut microbiome, helping with weight loss and overall health.
- A healthy microbiome is a diverse microbiome. A plant-based diet is the best way to achieve this.
- It isn't necessary to opt for a strictly vegan diet, but it's beneficial to limit meat intake.
New research shows that following a vegan diet for about 4 months can boost your gut microbiome. In turn, that can lead to improvements in body weight and blood sugar management.

Nearly 20 years have passed since the journalist Malcolm Gladwell popularized the term tipping point, in his best-selling book of the same name. The phrase denotes the moment that a certain idea, behavior, or practice catches on exponentially and gains widespread currency throughout a culture. Having transcended its roots in sociological theory, the tipping point is now part of our everyday vernacular. We use it in scientific contexts to describe, for instance, the climatological point of no return that we'll hit if we allow average global temperatures to rise more than 2 degrees Celsius above preindustrial levels. But we also use it to describe everything from resistance movements to the disenchantment of hockey fans when their team is on a losing streak.
