How do we know the climate is changing? 405 ppm Ice Core record of past 420,000 years: Upper, blue line = CO 2 level Lower, red line = temperature Temperature and CO 2 record from Vostok, Antarctica (Petit et al . 1999) Energy Bar Association
Should we Support these Technologies and Techniques? If so, how? State/Federal Levels? POTENTIAL SUPPORT TECHNIQUES TECHNOLOGIES/APPROACHES • R&D – ARPA-E, etc. • Wind onshore • Demonstration programs • Wind offshore • Solar – utility scale • Portfolio standards (RPS, CEPS, or EEPS) • Solar – distributed • Carbon/GHG tax • Storage – batteries • Carbon reduction requirements (X% by Yr Y) • Storage – other types • Financial (e.g., tax credits, green certificates, • CCUS bonds, removal of fossil subsidies) • Nuclear • Grants for climate adaptation • Energy Efficiency • Building codes and standards • Hydrogen/Fuel Cells • Technology/appliance performance stds • EVs – Next gen transportation • Charging stations, CAFE stds, mass transit • Active Adaptation Efforts • Funding for programs/projects overseas
