1. MIXING IT UP: We’ll need more than renewables to win the climate fight Ryan Fitzpatrick, Deputy Director Third Way’s Clean Energy Program rfitzpatrick@thirdway.orgrfitzpatrick@thirdway.org : @rdfitzpat

2. Cut power sector emissions at least 80% by 2050 Renewable sources will play major role But renewables alone? How Should we Address Climate Change?

3. Renewables are Growing Fast…

4. …But Still a Long Way to go.

5. Capacity Build-Out New Transmission Battery Storage Breakthrough Demand Response Even the Solutions are Challenging

7. Capacity Build-Out 484,000 onshore wind turbines 156,000 offshore 78,000,000 roof top PV 46,480 solar PV plants 2,273 CSP plants Plus wave devices, geothermal, tidal turbines… Even the Solutions are Challenging
