Views on RenewablesViews on Renewables• 2006 surveys conducted by ND Association of

RECs• 88 percent of North Dakotans believe utilities

should be required to get some energy from renewable resources.– 71% agreed even if their bills went up 5% as a

result.• 93% of North Dakotans say renewable energy

needs to be a legislative priority• 68% of North Dakotans choose wind or

renewables over coal if they had to pick just one fuel to handle all new generation needs.

SummarySummary

• Load growth driving electricity• Carbon driving pace of new power plants• Renewables are one part of a balanced

energy portfolio• Still need base load power• Support renewables, but oppose mandates• Carbon capture and storage must be

developed for existing power plants
