By David Shaffer for Star Tribune: The least-expensive battery to store energy from the electric power grid may be sitting in homeowners’ basements — the electric water heater. That is the surprising finding of research released Wednesday by the cooperative power industry, including Maple Grove-based Great River Energy, and an environmental group. Customers at many utilities already save money by heating water at night, taking advantage of low, off-peak electric rates. It requires a special electric water heater that holds a day’s worth of household water, but offers long-term savings. Now, a study by the Brattle Group, an economic consulting firm, says that the nation’s 50 million residential electric water heaters can address bigger challenges on the power grid, such as storing intermittent renewable energy from wind farms and solar arrays.

The popularity of electric cars in the UK has shot up over the last few years, with around 50,000 plug-in vehicles on the road, compared with just 3,500 in 2013. This huge increase in electric cars in 2015 has augmented because of a shift in the public's approach towards electric cars and a persistently refining public recharging network.
SGIP stands for Self Generation Incentive Program, a way to motivate consumers to use alternative energy sources to generate and store their own electricity. The SGIP pays energy storage users over a dollar per watt.
The Fourth Industrial Revolution means providing a personalised energy experience for the consumers, prosumers and utility companies. Consumers and prosumers want to see their impact on their bill, the grid and the environment - and they want to be accountable for their energy choices.
The introduction of more DERs on utility systems and at customer sites provides support for increased reliability and resiliency, if appropriately located and properly configured.
Daniel Oberhaus for Motherboard: The world, it seems, is falling in love with solar energy. Recent years have seen the increasing adoption of solar power around the world as an alternative energy source for everything from individual homes to the entire energy grid, with the United States’solar capacity having grown to 24 GW, a more than a 17-fold increase since 2008. Part of this rapid growth for solar infrastructure is the result of markedly more efficient solar energy cells, but in spite of these recent technological advances, transitioning to solar power still doesn’t make sense (at least economically speaking) everywhere. Installing photovoltaic systems can be pretty pricey, and home- and business-owners have to engage in a complex cost-benefit analysis to see if transitioning to solar power is an economically sound idea. The “pain-in-the-ass” factor of such calculations alone might be enough to turn people off of the idea of contemplating installing a photovoltaic system, so the folks at MIT came up with a solution: Mapdwell. Mapdwell maps the solar potential of entire cities by doing a cost-benefit analysis for every rooftop to determine if installing solar panels on that rooftop is worth the investment. All you do is enter your address into the program, and it will tell you the expected installation costs, the number of years it will take to earn back this investment from your photovoltaic system, the amount of carbon offset by the installation, as well as incredibly detailed installment specs such as the optimal panel tilt and the number of panels that could fit on the roof.

By Jeff Clabaugh for WTOP: Levi’s Stadium in Santa Clara, California, will set the stage for Sunday’s Super Bowl, and it will be a solar-powered event. Levi’s Stadium, which opened in July 2014, is the first professional football stadium in the NFL to open with LEED Gold certification, according to the Solar Energy Industries Association in Washington. Princeton, New Jersey-based NGR Solar LLC installed more than 1,150 solar panels at the stadium during its construction — enough to produce 375 kilowatts of peak power. The system can generate enough power in a year to meet electricity demand during every San Francisco 49ers home game. The solar panels cover three bridges that connect the stadium to the main parking lot and the “NRG Solar Terrace” that overlooks the field. There are 544 solar panels on the stadium roof and another 642 on the bridges, which also serve as canopies covering the bridges. Cont'd...
While tax credits for wind and solar power received long-term extensions in the year-end omnibus legislation enacted at the end of 2015, other types of alternative energy were left out - reports have suggested unintentionally - spurring some in Congress to seek a remedy in 2016
The European demand for renewable electricity documented by Guarantees of Origin now constitutes more than 13% of all electricity consumption in Europe (ca. 3,200 TWh) and approximately 40% of all electricity generated from renewable sources in Europe (ca. 1,100 TWh).
Tina Casey for CleanTechnica: The algae biofuel market is still in play even though the global petroleum market shows no real signs of lifting itself out of the doldrums, as two examples from different ends of the Earth illustrate. Over in Australia, researchers have come up with a new, low cost way to raise algae for biofuel, and here in the US the Department of Energy is moving forward with a new grant program to fund commercially viable algae production.

NREL's Sustainable Mobility Initiative approaches transportation as an integrated system, where travelers and transportation resources are viewed as a dynamic network that can be used to optimize mobility and significantly reduce related energy consumption and emissions.
Companies selling PV systems are concerned that if utilities add a set fee for solar customers to remain connected to the grid to take in electricity at times when the sun isn't shining, or if utilities decrease the retail credit for the times when customers send their excess generation back to the grid, people will be less likely to put panels on their roofs.
The map shows 40 jobs from entry, mid and advanced levels across four industry sectors: manufacturing, system design, project development and installation/operations, and it identifies more than 60 routes to advancement among them.
We're no longer a niche industry and there are many companies competing for customers. Growth like this is what happens when new technology intersects with drivers of change like the need to shift to clean energy, to modernize our infrastructure and give choice to consumers.
A solar-powered home reduces carbon emissions by 3-4 tons annually, equivalent to planting 100 trees every year).
