The $100 billion solar power industry is gaining a lot of attention both globally and domestically, attracting high-profile investment from Wall Street giants such as Apple, Google and Warren Buffett’s Berkshire Hathaway.

The United States is the world’s third-largest solar market, right behind China and Japan, and it’s growing rapidly not just because of private investment, but also because of the Obama Administration’s efforts to make progress against global climate change.

One of the most desirable locations for building domestic solar facilities is in the Mojave Desert—25,000 square miles of sun-baked terrain spanning southeastern California, plus portions of Nevada, Arizona and Utah. It’s no surprise that some of the world’s most sophisticated solar plants are popping up there, showcasing the latest developments in the industry.
