Texans don’t do small. When they build, they build big. And when they consume energy, they consume big energy—Texans have the highest consumption per household in a country that uses the most energy per capita in the world.

Now, a Texas coalition of elected officials, business leaders and community groups has connected the dots around energy consumption and the growing business opportunities for renewable energy and efficiency technologies.

The coalition, which includes former Shell Oil President John Hofmeister, has unveiled the “Renew Texas” plan. It calls on the Lone Star state to resume its role as the “energy capital of the world” by adopting policies to boost manufacturing and installation of clean energy products.

Top of the list: the Texans want 4 gigawatts, or 4000 megawatts, of solar power installed by 2020. That’s a big target, even for a big state. Total U.S. photovoltaic installation was about 200 megawatts, or 5 percent of that goal, last year, according to the Interstate Renewable Energy Council. And Texas wasn’t even one of the top 10 states for those solar systems.

The Texas plan also wants more stringent energy efficiency standards for new homes and certain appliances. It calls on the state legislature to require electric utilities to reduce energy consumption by 1 percent a year by 2015 and 2 percent a year by 2020.

Of course, it’s not the utilities that can reduce that consumption—consumers will have to do that hard work by using less electricity and natural gas.

The programs could generate thousands of technology-related, manufacturing and electrical services jobs, said the plan’s supporters.

How will all this be paid for? The coalition wants the state government to offer low-cost loans to schools, universities and local governments to improve their energy efficiency. Other programs could be funded partly by the federal government, according to the coalition. When Texans go fishing for government support, they also do that in a huge way.
