As the world’s undisputed energy epicenter, Houston has unsurprisingly played a pivotal role in the cultivation of cleantech across America. In fact, Houston’s sustainability initiatives are so strong, it ranks as the number one city in the nation for renewable energy use. According to The Green Power Initiative, the city relies on wind and solar energy for a whopping 92 percent of its power. Houston’s cleantech industry has made a major economic impact as well, generating $3.7 billion in VC funding, as stated by the Greater Houston Partnership. With ample funding and a growing energy tech sector, Houston rests as the heart of the nation’s cleantech revolution. 

As Houston continues to dominate the renewable energy industry, the city has fostered a collaborative cleantech community. Many of the city’s eco-conscious energy providers are dedicated to helping both homeowners and businesses make the easy switch to solar and wind energy. On the other hand, some of Houston’s cleantech companies are reinventing the ways that chemicals and even concrete are created in an effort to curb emissions and boost manufacturing efficiency. For each of these renewable energy leaders, finding cleaner, more affordable alternatives to old industry practices is essential to ensuring a greener future. Here’s a look at 13 renewable energy companies in Houston harnessing the power of nature to fuel a growing world.
