How ice-making air conditioners can help balance Southern California’s grid
Ice Energy produces an Ice Bear rooftop air conditioning unit, which uses cheap nighttime power to turn water to ice, and then uses the ice to reduce the electricity needed for air conditioning during the heat of the day.
Swanson's law states that with every doubling in the production and shipments of solar PV panels, there has been a 20% reduction in their cost. By getting to scale, with solar installations becoming widespread and common, Germany has reduced the cost of installed solar to half of what it is in North America. So we can observe, learn, and do the same.
With the right policies, China could get 40% of its electricity and 16% of its full energy mix from renewables by 2030. It would cost $145 billion a year from now until 2030, and bring savings of $55 to $228 billion a year in health benefits and reduced carbon dioxide emissions.
The Global Wind Energy Outlook 2014, co-published by the Global Wind Energy Council and Greenpeace, has found that global wind capacity could reach 2000 GW by 2030, meeting 20% of the global demand. Growth is versy strong in China, and India is also looking to wind.
