Tesla next week will announce two battery lines, one for households and another for utilities, that will store power from renewable sources, such as solar and wind, supplementing them when the sun goes down or the weather changes.
The Golden State's commercial rooftops and other urban areas present plenty of opportunity for power generation through small- and utility-scale solar installations, according to a study in the journal Nature.
The Providence-based developer of Deepwater Wind, what will likely be the country's first offshore wind farm, has closed on more than $290 million in financing for a five-turbine demo of the renewable power source.
While solar power is leading other sources for new electrical capacity, the distributed power movement, where homeowners and businesses deploy photovoltaic panels on site, is under assault by utilities and fossil fuel interests.
New data released from the International Renewable Energy Agency shows the price of solar-generated power will reach price parity or become less expensive than electricity generated by traditional methods in many countries.
