Rand withdraws energy study results  

The Rand Corp. has announced the withdrawal of its study on renewable energy expenditures issued Nov. 13 because of errors in the analysis.

Rand officials said the study – “Impacts on U.S. Energy Expenditures of Increasing Renewable Energy Use” – contained errors in the computer model and numerical assumptions on which findings were based.

The study examined total energy expenditures if a requirement was imposed that 25 percent of electricity and motor vehicle fuels used in the United States by 2025 would come from renewable resources.

Rand Vice President Debra Knopman said the errors might have an effect on the study’s results but no determination has been made.

“The Rand quality assurance process that we use to carefully review our studies failed to detect inadvertent errors in the treatment of existing subsidies for biofuels and the availability of existing hydropower capacity in the computer code, as well as some other details relating to how the renewable requirement is met and at what cost,” said Knopman.

“We deeply regret these inadvertent errors, accept responsibility for them, and are announcing them to set the record straight.”

Knopman said a revised analysis will be issued early next year.
