Supporters and opponents of a measure to increase the amount of renewable energy Arizona uses have spent millions and millions of dollars to try to influence your vote.

It’s nearly impossible to watch TV for even a few minutes and not see an ad for or against Proposition 127.

The measure would replace the state’s current renewable energy standards, which call for some utilities to generate at least 15 percent of their energy from renewable sources by 2025 with a mandate to generate half of their energy from renewables by 2030. The issue is controversial, as are the main sources of funding.

California billionaire Tom Steyer is largely bankrolling the effort to get it passed while APS’ parent company has provided much of the money in opposition.

To explain the pros and cons of Prop 127, Dylan Sullivan and Andrew Clark joined The Show. Sullivan is the policy director for the Clean Energy for a Healthy Arizona campaign, which supports the measure, he’s also senior scientist at the Natural Resources Defense Council. Clark is the state director for Americans for Prosperity, which opposes the initiative.

The fight over this ballot measure also has some Arizona politicians clamoring to make their opposition known. But have some gone too far? Some government agencies are facing claims that they may have improperly used public resources to discourage voters from supporting the measure.

One of the places where this dispute has cropped is in the Arizona Corporation Commission, which meets later this afternoon. KJZZ’s Will Stone has been reporting on the issue and joined The Show to talk about it.
