Tesla offers South Australia battery storage within 100 days

Tesla Motors CEO Elon Musk at Tesla Store opening in Westfield Mall, London, Oct 2013If only we could all be as optimistic, and energetic, as Tesla CEO Elon Musk. Even as Tesla gears up for mass production of the Model 3 electric car and a hoped-for annual production rate of 500,000 total cars by next year, Musk has found time to place a high-profile bet on the renewable energy part of Tesla's businesses. In this case, it has to...

Bipartisan governors’ group urges Trump to back solar, wind power

wind farmThe new presidential administration seems poised to take a radically different approach to energy policy than its predecessor. That approach is founded on denial of accepted climate science, and an expressed desire to promote the fossil-fuel industry, including the so-called revival of coal. But while the White House prepares to execute what looks...

Tesla’s battery farm on Kauai opens, large-scale solar energy for Hawaii

Solar Panels by Flickr user Chandra MarsonoEven before Elon Musk engineered Tesla's acquisition of SolarCity, the two companies were collaborating. SolarCity was already controlled by Musk, who believes its solar-energy business can be reinforced and complemented by Tesla's energy-storage business. Last year, Tesla announced a joint project with SolarCity to install a large battery farm...

U.S. household energy costs hit 50-year low

Photovoltaic solar panels on roof of Honda Smart Home at UC-Davis, CaliforniaSubstantial growth in U.S. renewable-energy capacity will undoubtedly have a positive environmental impact. But the reduction in carbon emissions renewable-energy advocates aim to achieve does not exclude potential benefits to consumers. Because as renewable-energy generating capacity has expanded significantly over the last decade, household...

Wind energy capacity in Europe now exceeds total coal output

wind farmWhile homeowners are more familiar with photovoltaic solar panels, large-scale wind power is an increasingly important part of the growth in renewable energy. For the first time, the total installed capacity of wind energy in Europe now exceeds the total output of electric powerplants fueled with coal. And that imbalance is likely to grow as more...

Solar power hits new U.S. heights: utility use exceeds home panels

Photovoltaic solar power field at Volkswagen plant in Chattanooga, TennesseeNo matter how you measure it, 2016 was a major year for solar energy. More solar-generating capacity was added last year than either natural gas or wind, according to the U.S. Department of Energy. A study by investment bank and research firm Lazard found that utility-scale solar has now become the single cheapest form of unsubsidized electricity...

Big energy hugely underestimates electric cars, renewable power

2016 BMW i3Mass adoption of electric cars and renewable energy could significantly decrease global consumption of fossil fuels. But does the established energy industry view these new developments as a threat? In a recent report, ExxonMobil said coal could continue to provide the majority of the world's electricity-generation capacity in 2040, and that...

3 California battery storage sites come online, one from Tesla

Tesla and SolarCity energy storage array on Ta'u, American SamoaLong a leader in the push to reduce vehicle emissions and switch to renewable energy, California marks another milestone this week. The last of three battery energy-storage sites will come online in Southern California, providing storage and buffering for unpredictable renewable energy. Together, the three sites add up to capacity equal to fully...

Which oil companies invest in renewables, electric-car services?

Shell fuel station in EuropeIf electric cars are adopted by mass-market buyers in years to come, that will lead over time to notably lower oil consumption. So what are oil companies doing to prepare for that possible outcome? Some continue to doubt whether electric cars will constitute a serious threat to their business in the coming decades—but others are branching...
