Renewable-energy generation costs are falling like photons onto a solar panel. By 2020, it's expected all types of renewable-energy generation will be able to compete with fossil fuels on cost. That's right: saving our environment will actually save electric utilities some money, too. DON'T MISS: Two-thirds of world's new energy capacity in 2016... All renewable energy types to be cost-competitive by 2020: report

For much of last year, U.S. Energy Secretary Rick Perry pursued a plan that, in essence, would prop up the financially challenged U.S. coal and nuclear industries. His proposal, submitted to the Federal Energy Regulatory Commission last fall, provided financial subsidies to electric-generation plants that kept 90 days of fuel onsite. Natural-gas... 
Remember all those brownouts we experienced last week because everyone plugged in their electric cars? No? Oh right, that didn't happen. It still isn't happening. And it's unlikely to ever happen. That's the conclusion of a study by the Natural Resources Defense Council (NRDC), using infrastructure investment data from California's biggest... 
Call it the Ikea mindset. On populated islands, space is at a premium, just like those stereotypical Swedish kitchens you see when you stroll through your local assemble-it-yourself retailer. That space restriction is a major reason fossil fuels remain a better power-generation option than renewables on populated islands that have just experienced... 
Five years ago, an electric-utility think tank issued a dire warning to its members: Your century-old business model is ending. The continually falling costs of renewable energy generation, especially solar panels, would begin to erode utilities' business from its most profitable customers, the study said. Now, in Germany—hardly known for... 
Electric vehicles have the potential to upend energy markets as their adoption becomes more widespread. But how much of an effect will they have? And on which specific markets? According to a recent report by Wood Mackenzie, the global power grids are likely safe for quite a while, but another market may be turned on its head. DON'T MISS: Decline... 
A shipyard in China has built what it says is the world's first all-electric cargo ship, capable of hauling 2,000 metric tons of lading some 50 miles on a single charge. The ship, built and operated by CSSC Offshore & Marine Engineering (Group) Company Ltd under the China State Shipbuilding Corporation Group, may not have the gross tonnage or... 
Tesla CEO Elon Musk made a bet that he'd build the world's largest lithium-ion battery in Australia in 100 days. If his company failed, Musk would personally pay for the project, but the battery is now ready for its first test ahead of full operation—and on schedule. The massive 129-megawatt-hour battery will plug into South Australia's... ![Estimated U.S. energy consumption in 2016 [graphic: Lawrence Livermore National Laboratory]](https://images.hgmsites.net/tmb/estimated-u-s-energy-consumption-in-2016-graphic-lawrence-livermore-national-laboratory_100634001_t.gif)
One of the interesting side effects of plug-in electric cars turns out to be a greater awareness of energy sources and uses. A 2012 California study, for instance, showed roughly four out of 10 electric-car drivers either had or were considering solar panels to provide electricity to their home. And because electric cars everywhere in the U.S... 
Sometimes a picture is truly worth a thousand words. In the case of the rapidly rising rate of solar installations for electricity generation, numerous forecasts by internationally respected bodies have proven woefully conservative. The chart in the tweet below, created by Auke Hoekstra at the Technical University of Eindhoven, The Netherlands...
