Investment in renewable energy drops as fossil fuel use rises
Global investment in renewable energy is on the decline, according to the International Energy Agency (IEA). The energy watchdog says there's a significant contradiction between the statements governments make regarding their attitudes to renewables, and the tangible action being taken. Investment fell by seven percent to $318bn last year.
Tesla's next California energy storage project may be its largest yet
Tesla's giant Australian energy storage facility may seem small in the near future. Pacific Gas and Electric has submitted proposals for four new energy storage projects to the California Public Utilities Commission, one of which is for a facility at its Moss Landing substation that could output 182.5MW over the course of four hours -- that's more than 3,000 of Tesla's Powerpack 2 units. For context, the Australian location outputs 'just' 129MW. The project would have a total 1.1GWh capacity, which fits with Elon Musk's recent hints that Tesla could have a "gigawatt-hour scale" deal within months.
Tesla closes solar installation centers as part of layoffs
Tesla's recently announced layoffs may hurt its solar panel business particularly hard. Reuters sources and leaked documents have revealed that Tesla is closing roughly a dozen solar installation centers in nine states as part of the job cuts. There will still be about 60 facilities left afterward, but this would also end a Home Depot partnership that was reportedly responsible for half of Tesla's sales in the category.
Samsung targets 100 percent renewable energy use by 2020
Samsung has announced plans to power its US, Europe and China operations entirely by renewable energy sources within two years. It's already making good on its sustainability commitment in Korea, where the company is installing 42,000 square meters of solar panels in its Digital City, and is working on generating geothermal power at Pyeongtaek campus and Hwaseong campus by 2020.
Tesla says it’s being underpaid because its batteries are too fast
It looks like Tesla's batteries are too fast for their own good. As the Sydney Morning Herald reports, the company claims it's not being properly paid for the electricity its South Australia battery farm is generating for the country's power grid. And Tesla says its because its batteries supply electricity faster than the Australian Energy Market Operator (AEMO) can register. The current standards are based on response rates for fossil fuel generators, but Tesla's batteries can respond much more quickly than they do. "Tesla estimates that the Hornsdale Power Reserve battery has delivered 30 to 40 percent of its services to frequency markets without being paid due to existing AEMO technical specifications being written based on fossil fuel generation assets," Tesla said.
MIT embarks on ambitious plan to build nuclear fusion plant by 2033
MIT announced yesterday that it and Commonwealth Fusion Systems -- an MIT spinoff -- are working on a project that aims to make harvesting energy from nuclear fusion a reality within the next 15 years. The ultimate goal is to develop a 200-megawatt power plant. MIT also announced that Italian energy firm ENI has invested $50 million towards the project, $30 million of which will be applied to research and development at MIT over the next three years.
Researchers improve spinach-based solar cells by adding blackberry dye
Biohybrid solar cells aren't nearly as efficient as standard silicon panels, but including natural materials in renewable energy could make it more cost-effective. Scientists have refined one design based on the proteins in spinach leaves by adding natural dye extracted from blackberries, a combination which apparently produces much more voltage than the greens alone.
Bitcoin miners turn Quebec's cheap energy into cold cash
Bitcoin mining is a weird industry. Vast banks of dedicated computers solve complex equations to generate hashes worth a fraction of a coin, consuming huge amounts of power in the process. For such operations to be economically feasible nowadays, miners need the cheapest electricity possible.
Tesla's latest smart power grid experiment begins in Canada
Tesla's experiments with smart power grids are headed further North. Canada's Nova Scotia Power recently finished setting up a pilot project that will use a combination of Tesla's Powerwall 2 home batteries and utility-grade Powerpack batteries to create a more reliable wind power system. The Elmsdale-based Intelligent Feeder Project fills gaps in the electrical grid by topping up the Powerpacks whenever a nearby wind turbine system generates excess power, and delivering that stored energy to local homes (including those with Powerwall 2 batteries) when there's an outage or the turbine system falls short.
Device provides years of power through temperature swings
Eventually, you might not need a battery or a conspicuous external power source to keep a device running for years on end. A team at MIT has created a device that produces energy by exploiting the temperature swings that occur between day and night. Known as a thermal resonator, it uses a hybrid of materials that produce both high heat conduction and capacity. A copper or nickel foam at its core is coated with graphene to boost its conductivity, and is infused with a phase-changing material (octadecane) that serves as storage. Effectively, one side of the device is always capturing heat while the other is storing it -- you just have to harvest that energy with conventional techniques.
Tesla’s big battery is undercutting Australia’s energy cartels
When Tesla installed the world's largest lithium-ion battery in South Australia last year, it came with the promise that it would revolutionize the way electricity is produced, stored and sold in a region known for blackouts and market monopolizing. Less than two months later, that promise has been delivered to the tune of a multimillion-dollar saving, as the Tesla big battery essentially noped an attempt by Australia's energy cartel to capitalize on power fluctuations and send the market into overdrive.
Tesla will create 'virtual power plant' with 50,000 Australian homes
Tesla isn't done bolstering Australia's power grid just because its giant battery farm is up and running. South Australia premier Jay Weatherill has unveiled a partnership that will provide 5kW solar panels and Tesla Powerwall 2 batteries to "at least" 50,000 homes in a bid to create the largest-ever "virtual power plant," where homes contribute their surplus energy to the grid. The move will theoretically stabilize the Australian state's electricity infrastructure, reducing the blackouts and surging prices that have plagued the region in recent times.
Americans are using less energy by staying at home
Americans are using less energy -- paradoxically, by spending more time indoors, according to a new study in the journal Joule. But researchers point out that keeping more lights on was offset by lifestyle changes that kept people inside instead of roaming around offices and retail stores -- like, say, online shopping and working from home. Despite energy consumption worldwide increasing every year, this slight uptick in American hermitage reduced national energy demand by 1.8 percent over a year.
US coal industry saw little growth in 2017 despite White House push
The Trump administration has been eager to prop up the US coal industry despite evidence that it's in a steep decline. But did it have much of an effect? Not really. Reuters has obtained preliminary Mining Health and Safety Administration data showing that there was negligible job growth in coal mining during 2017. The field added a total of 771 jobs, reaching 54,819 -- a figure still near historic lows. There was growth in Pennsylvania, Virginia and West Virginia, but that was largely offset by mine closures in several states, including Ohio (414 jobs lost) and Texas (455).
Audi smart home battery grid creates a 'virtual power plant'
Audi isn't going to let rival automakers like BMW and Tesla corner the market on home batteries. The German badge is testing a Smart Energy Network where solar-powered batteries not only help your home minimize use of the electrical grid, but talk to each other. The result is, as Audi put it, a "virtual power plant" -- households collectively feed power into the grid and help balance overall consumption.
Nearly all new US electricity capacity was renewable in 2017
Renewable energy played an important role in the US last year... although you might not want to cheer too loudly. Data from both the Rhodium Group and the Energy Information Administration shows that solar and wind power represented 94.7 percent of the net new electricity capacity (15.8GW out of 16.7GW) added in 2017. However, that's mainly because fossil fuel power continued to fade away. Electrek noted that plant closures removed 11.8GW of utility-scale fossil fuel power from the equation -- this was more a testament to the decline of coal than a triumph for green tech.
Thieves swipe a portion of China's solar road
Solar roads have plenty of potential problems, such as damage and snow, but theft? Apparently that's a concern, too. China's Qilu Evening News reported that thieves carved out a small (5.9in by 73in) portion of an experimental road in Jinan on January 2nd, a mere five days after its December 28th debut. While it's tempting to suggest this was an accident, officials said the missing segment was "neatly cut," and didn't appear to have come loose on its own.
Renewable energy outstripped coal use in the UK for most of 2017
The UK has been working to significantly reduce its carbon emissions and with that effort, it hit some major green milestones this year. In April, the country went a full day without coal-generated power for the first time in 135 years. And in June, the country saw more than half of its energy being generated by renewables (i.e. solar, wind, hydropower and biomass) for the first time.
Hackers shut down plant by targeting its safety system
Hackers have already attacked critical infrastructure, but now they're launching campaigns that could have dire consequences. FireEye reported that a plant of an unmentioned nature and location (other firms believe it's in the Middle East) was forced to shut down after a hack targeted its industrial safety system -- it's the first known instance of a breach like this taking place. While the digital assault was clearly serious in and of itself, there are hints that it could have been much worse.
The colossal ITER fusion power facility is halfway finished
Fusion remain the ideal solution for energy woes: Limitless production with no harmful waste. Scientists haven't managed to get a functional (and productive) installation up and running, but that hasn't stopped them from trying. The biggest project is the colossal ITER tokamak fusion reactor, an international project based in France that aims to start its first experiments in 2025. Today, its handlers announced that the massive installation is halfway finished and headed toward a completion date of 2021.
