Celebrating Earth Day, One Solar Project at a Time

As a company that’s built on the guiding principles of building a sustainable, green economy, Earth Day is a particularly meaningful day for us here at NRG Solar. This year, Earth Day’s focus is on highlighting the growing evidence of climate change around the world, and what we can do to collectively combat the problem.

For many, it may seem that renewable energy is a promising, yet far-off future.  However, solar is a promising and very viable solution.  It is a CO2 free generation technology that can be implemented now.

To celebrate Earth Day and our commitment to an eco-friendly future, below we offer a few sustainable highlights from some of NRG Solar’s recent projects.

  • The Alpine Solar Station in Lancaster, California—currently the largest operating photovoltaic (PV) facility in the state—is helping reduce water use in the area by 99 percent (compared to the land’s previous usage). The clean energy being produced at the plant avoids the annual emission of 36,000 tons of carbon into the atmosphere, the equivalent of taking 6,600 cars off the road.
  • Zero-carbon power generation at the Borrego I Solar Generating Station in San Diego County is helping avoid the annual emission of 33,000 tons of carbon into the atmosphere. That’s the equivalent of taking 6,000 cars off the road.
  • The Ivanpah Solar Electric Generating System, which is slated to be the largest solar thermal project in the world when completed this year, will avoid the emission of 450,000 tons of carbon annually into the atmosphere. That’s a total of 13.5 million tons over the plant’s first 30 years, and the equivalent of taking approximately 81,800 cars off the road annually. Because Ivanpah uses dry cooling for steam condensing, it also minimizes water consumption.
  • At Arizona State University’s Tempe campus, NRG installed solar panels to make up the PowerParasol parking structure. Because of this installation some 15,000 tons of carbon dioxide is being offset – the equivalent of taking roughly 3,000 cars off the road.

Like we always say here at NRG, solar power is not just one solution—it’s many. And outside of solar, there are other sustainable energy sources that can contribute to a greener planet, such as wind and biomass (both solutions that NRG develops as well).
