A photographer shares his unique perspective on the growing wind and solar power industries.
Large Scale Solar Power in Nevada
Some large-scale solar power installations concentrate sunlight on a pipe of oil that, once heated, boils water to generate electricity. Others, like this one in Nevada, reposition mirrors to focus sunlight on a central receiver tower, in which molten salt powers the generator.

When seen from thousands of feet in the air, solar installations and wind turbines become abstract works of art: a glinting fractal of metallic petals circle a single pale stamen, and sharp, slender flowers tower above the earth.
Futuristic and abstract as these sites may seem, the concrete reality is that solar and wind energy are thriving. (Explore what your state’s energy mix will look like with 100% renewable energy.)
Each year, government incentives, shifting public policy, and technological advances make these sources of clean, renewable energy more attractive to corporations and individuals alike. And in the United States last year, solar employed more people than traditional coal, oil, and gas combined.
Wind Turbines Stands Tall in California

Wind Turbine’s with Three Curved Blades
A wind turbine’s three curved blades can be as long as 200 feet; as they spin, they turn a shaft connected to an electric generator. Critics point to the blades’ deadly impact on flying life, but windmills are actually less dangerous to birds and bats than cars, power lines, and high-rise buildings.
Wind turbines and solar panels in the Mojave Desert, California, provide renewable clean energy. By 2050, 50% of California’s energy could be produced by solar plants and onshore wind.
Spread over 400 acres, Nevada Solar One is a massive project built in the hot, dry desert just south of Las Vegas. The plant uses 760 parabolic trough concentrators with more than 182,000 mirrors that concentrate the sun’s rays onto more than 18,240 receiver tubes. Every year, the projected amount of CO2 emissions this plant avoids putting into the atmosphere is equivalent to taking approximately 20,000 cars off the road.
Rows of pipe produced by United Spiral Pipe stretch across a lot in California. These custom steel pipes are primarily used in the North American oil and gas industry; there are about 2.5 million miles of oil pipeline in the United States.

Some worry it’s too little, too late. Scientific consensus agrees that the need for green energy is greater than ever: the carbon emissions of an average Westerner melt 323 square feet of Arctic ice a year, contributing to global sea level rise.

Turning from fossil fuels to an array of clean, renewable energy sources—like solar and wind—is a step in the right direction. And for a Your Shot photographer whose work was recently featured as part of National Geographic’s #myclimateaction challenge, the future is bright.

EYE IN THE SKY
A native of Bulgaria, Jassen Todorov is a violinist and music professor at San Francisco State University. He’s also a pilot and a member of National Geographic’s Your Shot community, regularly sharing photographs taken from his four-seater plane.
“In my twenties, I was freaking out about being able to find a job” as a musician, Todorov laughs. “So I thought, ‘What if I became a pilot?’ Well, I did, and I haven’t looked back.”
But he’s certainly looked down. “It opens up a whole new world,” he says. “Flying from point A to point B, there’s so much to discover in between…it’s just a matter of looking and realizing ‘Oh my god, this is incredible, I better photograph this.’” (Meet another Your Shot photographer documenting climate change.)
Concord Naval Weapons Station Superfund Site. since being listed as a Superfund site, the 12,800-acre Concord Naval Weapons Station has seen some recovery from its three decades of heavy metal contamination.
Oil Wastewater Fracking for natural gas and drilling for oil displace enormous volumes of wastewater, in Kern County, California. The county is also home to the Kern Water Bank, a 32-square-mile underground water reserve currently in the hands of private corporations.
Todorov started intentionally documenting both the good and the bad: he saw fascinating renewable energy installations, but also oil spills, Superfund sites, and massive pools of toxic waste.
“Everybody’s trying their best, I think—solar power plants and wind turbines are being built all over,” Todorov points out. “They’re beautiful to look at from above; some of them are very futuristic. Knowing that they’re for clean and renewable energy just makes you happier—there is hope!”
