Research & Commentary: Colorado Renewable Portfolio Standard
Colorado legislators are bucking the national trend and considering a proposal that would boost the state’s renewable portfolio standard (RPS). The RPS requires utilities to obtain a specified percentage of their power from intermittent renewable sources by a certain date. Twenty-two of the 29 states with such mandates in place have considered changing those laws over the past two years.
Colorado’s current RPS requires cooperatives and their utility suppliers to get 10 percent of their electricity from renewables by 2020. SB 252 would increase the percentage, mandating 25 percent of their electricity come from renewable sources by 2020.
Supporters of the RPS say the mandates are necessary to reduce pollution, will lead to the creation of “green” jobs, and will only marginally increase electricity prices. However, there is little evidence the mandate will benefit the environment. Renewable sources such as wind and solar technologies are intermittent and thus require fossil fuel generators for backup. Running fossil fuel generators in this way can emit more pollutants than when used as primary power sources.
A report from the Colorado-based analytics company Bentek Energy evaluated this problem and found, “While meeting RPS-mandated wind generation requirements appears to have a minimal impact on CO2, it appears to appreciably increase SO2 and NOX.”
A 2011 joint report by the American Tradition Institute and Beacon Hill Institute found the mandate would increase Colorado’s electricity prices by an average of 3.75 cents per kilowatt-hour (kWh), a 40 percent rise. By 2015 this will lead to the loss of 6,000 to 29,000 jobs, according to the Beacon Hill Institute estimates.
Rolling back the Colorado renewable portfolio standard, instead of increasing it, would help keep energy more affordable for consumers, attract more business investment, and increase job creation. It would also allow more efficient use of these resources and minimize dangerous emissions. Colorado should not pick economic winners and losers by mandating the use of certain types of energy; instead, the state should encourage the development of economically competitive energy sources through non-distorting tax and regulatory policies.

The Status of Renewable Electricity Mandates in the States
The Institute for Energy Research analyzed the practical effects of renewable electricity mandates and found states with mandates have on average 40 percent higher electricity rates than those without such mandates.
Study of the Effects on Employment of Public Aid to Renewable Energy Sources
Researchers at King Juan Carlos University in Spain found each “green job” created in Spain cost about $750,000. Electricity rates would have to be increased by 31 percent to account for the additional costs of renewables.
How Less Became More: Wind, Power and Unintended Consequences in the Colorado Energy Market
Bentek Energy, LLC, a leading energy markets information company, evaluates the “must take” provisions of Colorado’s Renewable Portfolio Standard, which forces coal plants to accommodate the intermittency of wind power by “cycling” generating units. The report finds the requirement results in inefficiency and produces significantly greater emissions.

U.K. Study: Renewable Fuels Kill Jobs
A 2011 study by Verso Economics, a UK-based economic consultancy, found renewable power killed 3.7 jobs in Great Britain for every “green job” created. The UK’s “renewable obligation” cost the country an additional $2.3 billion in 2009-10 when all economic costs, including electricity prices, were considered.
