100% Renewable Energy

• StratoSolar PV power plants provide 100% renewable,  low-cost, sustainable, zero-carbon electricity generation from a combination of solar energy and gravity energy storage. 
• The power plants are a complete, dispatchable, lower cost, direct replacement for coal and natural gas power plants. 
• They need no backup fossil fuel generation, no electricity grid changes for transmission, and no additional electricity storage. 
• They offer significantly lower cost generation and clear environmental and energy security benefits over fossil fuels. 
• They can scale from small MW scale plants for islands, remote locations and/or developing countries to very large multi-GigaWatt scale plants positioned near large urban areas. 
• They can eventually meet the complete world energy demand using only clean, safe, sustainable solar energy without stressing available land or natural resources. Intermittent renewable solar and wind, because of long duration, multi-day intermittency, can only ever provide a partial or very expensive energy solution.
