Using Geothermal Solutions to Desalinate Oil Field Water

Clean water — it’s a precious resource in hot demand right now, for more than taking a shower or watering our crops. The United Nations projects the world’s population will grow by another billion people, to 8.4 Billion, by 2030. More people means more need for food, water, electricity, and other necessities. Beyond the obvious demands for water, our increasing appetite for electricity also requires water — and plenty of it. Most of the electricity generated in the U.S. uses water in some capacity.

Listen Up: Can We Get To 100 Percent Renewables?

We’ve made great progress with renewable energy — but from an almost zero base we still have a long way to go. Fortunately, the path is clear. California is already over 12 percent with a combination of hydroelectric, wind and solar (unfortunately not much hydro this year). Getting to 50 percent only requires the deployment of existing technology. But can we get to 100 percent?

Iowa and the Renewable Fuel Standard

A native of Leland, Governor Terry Branstad was elected to the Iowa House in 1972, ’74 and ’76, and elected as Iowa’s lieutenant governor in 1978. He was Iowa’s longest-serving governor, from 1983 to 1999. As the state’s chief executive, he weathered some of Iowa’s worst economic turmoil, during the farm crisis of the ‘80s, while helping lead the state’s resurgence to a booming economy in the ‘90s.

A Partial Solution To California’s Water Problems

A new report, Clean Energy Opportunities in California’s Water Sector, offers what could be a partial solution to California’s water problems. The authors, Juliet Christian-Smith and Laura Wisland from the Union of Concerned scientists, primarily focus on the 20 percent of California’s electricity that is consumed by the water sector. They point out that most water and wastewater utilities own assets (land, reservoirs, ponds etc) that could be used to produce renewable energy.
