Lightning In A Bottle: Using Tax Policy To Solve Renewable Energy's Storage Challenges, Roberta F. Mann

Roberta F Mann

Government support for renewable energy has increased the generation of electricity from intermittent renewable sources such as wind and solar. The United States delivered almost $14 billion in renewable energy tax incentives in 2011. More renewables in the electricity mix means lower carbon emissions. Intermittent energy sources can reliably provide up to 20 percent of the electricity mix. However, increasing renewable generation above 20 percent requires better weather forecasting, improved coordination, increased grid capacity or more storage capacity. Batteries and electrical energy storage technologies straddle two major energy sectors: transportation and the grid. Unfortunately, compared to other types of technology, …
