Two Main Issues
Storage (Dealing with Intermittency) Relative Cost

Thermal Energy Storage
Approximately 93% efficient

Battery Banks
• Approximately 90 % efficient
• Common uses Lead Acid batteries

Pumped-storage Hydroelectricity
• Approximately 75% efficient

Prospects• Background shows solar ‘hotspots.’
• Study by IAE (International Energy Agency) asserts that Solar Energy will be main source of global energy within 50 years. Optimistic?
• >50% of cost is Photovoltaic cell

Prospects cont’d
• Economies of scale • Small scale vs. large scale
• ~8000:1
