Tesla’s solar and battery project in Hawaii: we do the math
Tesla’s summer announcement of the world’s biggest battery-storage system in South Australia characteristically kept key details confidential. Fortunately, while mystery and mystique still shroud that project, more can be unearthed or inferred for Tesla's solar panel and battery energy-storage deployment in Kauai, Hawaii, which came... 
The Trump administration hasn't been coy about trying to champion traditional fossil fuels while downplaying the importance and falling costs of renewable energy. Earlier this year, Department of Energy secretary Rick Perry, previously governor of fossil-fuel producer Texas, called for a 60-day review of the United States' energy grid. The stated... 
For 50 years, the state of California has led the United States when it comes to renewable energy and electric cars. The state features many programs to incentivize electric-car ownership, and 29 percent of the state's 2016 energy production came from solar, wind, and other renewable power sources. California is now preparing for a future in which...

The Trump administration has reneged on one aspect of a promise widely discussed throughout the 2016 presidential campaign: reviving the coal industry. President Donald Trump declared the United States coal industry would thrive under his watch, but the Trump administration and the Energy Department have just delivered a blow to the... 
Solar power provides 10 percent of California's energy supply, which meant electric-grid operators had to be prepared for potentially disastrous effects during Monday's solar eclipse. To the surprise of many, there were no serious repercussions as the moon blocked a significant source of energy for many California utility companies. The solar... 
The Senate Committee on Appropriations recently exhibited a quality somewhat rare in U.S. politics these days: bipartisanship. The committee released a lengthy report on the 2018 fiscal year budget for the Department of Energy that walks away from the Trump Administration's efforts to defund clean energy. In fact, the committee voted on a... ![Photovoltaic solar panel installation on house, Fremont, California [image: Shiva Singh]](http://images.hgmsites.net/tmb/photovoltaic-solar-panel-installation-on-house-fremont-california-image-shiva-singh_100615724_t.gif)
The purchase of an electric car that plugs into the power grid to recharge its battery often gets drivers thinking about the source of their energy. We haven't seen data from recent years looking at the overlap between electric-car drivers and home solar panels. But early analyses in California indicated as many as four in 10 electric-car drivers... 
The future of energy production remains in considerable debate, but some new research provides a more optimistic view for a lower-carbon future. Sources for new and replacement energy production remain uncertain, especially the degree to which renewable sources can replace those based on fossil fuels. Even with the newer, optimistic predictions... 
The U.S. is coming up to its Independence Day holiday, in which we celebrate the Declaration of Independence from England and reflect on our history and traditions as a nation. This is an interesting time to do that, and there's a cynical argument to be made that backroom politics is as American as apple pie and bald eagles. Which brings us to the...
