Can solar power compete with fossil fuels?

Deutsche Bank says that solar electricity in the US is on track to be as cheap or cheaper than average electricity-bill prices in all but three states by 2016—assuming that the federal government maintains the 30% solar investment tax credit it currently offers homeowners on installation and equipment costs.

But even if the credit is reduced to 10%, solar power would still achieve price parity with conventional electricity in some 36 states by 2016.

Canada does not have a solar tax credit.

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 and Making US Solar Scale Like Germany

Can the U.S. halve the price of solar?

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.

Wind Could Provide Almost One-Fifth Of Global Electricity By 2030

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. 

America Could Get 10 Percent Of Its Energy From Solar Power By 2030

Today, America gets 0.23% of its electricity from solar PV. By 2030, it could be getting 10%. 

Amazing? Not if solar PV continues to grow in installed capacity at the current 22% a year, driven by rapidly falling prices.
