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
