In addition to strong winds and lots of land Texas’s secret, is its lack of regulation. Wind developers rave about the fact that they need few state permits to build a wind project. They deal mainly with local officials, who are generally receptive (energy, after all, is a well-loved commodity in Texas).

California, by contrast, has all but stifled wind developers. The state built several big wind farms in the 1980s — but has added very few since, because of the cost and delays of complying with stringent state environmental regulations. Read more about Texas and California wind laws.
