Thermal energy storage (TES) is a load management technology with a significant potential to shift load from peak to off-peak demand hours.
The Thin Film Solar Cell Industry In Transition: Knockout Phase Is Over - Profitability And Vertical Integration Next
The implementation of PV into buildings should not be considered an added novelty product supplementing current construction materials, but rather be seen as an integrated part of roofing and facade material that could add substantial value to building material suppliers' range.
U.S. energy secretary, Dr Ernest Moniz, spoke at the Opening General Session at AWEA’s WINDPOWER 2015 event today in Orlando, Florida. Moniz stressed that wind power is an important and necessary part of the solution to climate change. Wind could provide five times what it provides today, he said, with a goal of one trillion kilowatt-hours per year in America. To get there, new technologies are needed to boost the industry is areas where it is not yet cost-effective or as profitable as other energy sources. Moniz mentioned better siting methods, improved drivetrains, and longer blades. On the show floor, companies are certainly bringing some new and improved technologies to the wind market.

Giannoumis has found that using PictometryOnline™, with access to high-resolution aerial imagery and analytical tools, combined with solar roof reports and CAD-compatible .dxf files provided by EagleView Technologies, is the key to maintaining productivity. This technology is also offering the company a new level of profitability and accuracy throughout the system design process.
China continued to deploy wind power at a remarkable rate, installing an estimated 23.3 GW in 2014, a 45% increase over 2013. China accounted for 45% of the 51 GW installed globally in 2014, representing $94.6 billion in revenue.
Data from AMP and Ohio State shows that wind power in Ohio is a good deal for its customers, and that its price is competitive with, and in some cases significantly cheaper than, other sources of power.
Scientists in South Korea have developed a new way to store energy that also offers a solution to a growing environmental problem. Reporting their findings in the IOP Publishing journal Nanotechnology, the research team successfully converted used cigarette butts into a high performing material that could be integrated into computers, handheld devices, electric vehicles and wind turbines to store energy. According to the study, this material outperforms commercially available carbon, graphene and carbon nanotubes. It may someday be used to coat the electrodes of supercapacitors: electrochemical components that can store extremely large amounts of electrical energy. "Our study has shown that used cigarette filters can be transformed into a high performing carbon-based material using a simple one step process, which simultaneously offers a green solution for meeting the energy demands of society," says co-author Professor Jongheop Yi of Seoul National University.

By Eleanor Goldberg for The Huffington Post: While there are many technologies out there than can effectively remove salt from water to make it drinkable, most are expensive and rely heavily on electricity –- rendering them all but useless in remote, off-grid villages. That’s why a group of engineers from MIT, backed by Jain Irrigation Systems, set out to invent a system that relies on solar energy to bring clean drinking water to rural areas in India, The Washington Post reported. About 21 percent of India’s communicable diseases are related to unsafe water, according to the World Bank. According to MIT researchers 60 percent of India has brackish groundwater -- while not toxic, that water is too salty to be ideal for human consumption. The group, which took home the first-place Desal Prize last month in the “Securing Water for Food” challenge, used a method called electrodialysis, which relies on electricity and ultraviolet rays, according to the aid organization. The first-place winners were awarded a $140,000 grant. Cont'd...
State leaders in the Northeast should keep watch of neighboring states to share best practices and innovative solutions for microgrids. Stakeholders can also look nationwide to other states including California and Illinois, where officials are creating incentives and addressing regulatory challenges.
While buying a solar panel one must keep in mind various factors like where it will be installed, purpose; commercial or residential use, and budget.
A road made of solar panel material is producing more energy than the creators expected. Engineers created a solar power bike path near Amsterdam that is over 200 feet long last year, and the road generated over 3,000kwh during the first six months, according to Al Jazeera, enough energy to power a house for a year. The company that created the road, SolaRoad, claims that means the road can produce 70kwh per square meter per year. The road is made of solar panels, glass, rubber and concrete. The road can either power street lamps or add power to the general grid. Over 150,000 cyclists have ridden on bike path without a problem since the project began. The path is made to be non-reflective and to prevent skidding. SolaRoad is still refining its materials to make them even more weather proof and efficient, and the company hopes to expand to larger areas in the future.
The installation involved locating where the fastener is going, driving the fastener into the metal deck underneath the insulation and membrane, sliding the PowerGrip over the fastener head, and hot air welding it in place.
Hawaii lawmakers voted 74-2 this week to pass the nation's first 100% renewable energy requirement. The measure, House Bill 623, makes Hawaii a global leader in renewable energy policy by requiring that 100% of the islands' electricity must be generated from renewable energy resources--such as wind, solar, and geothermal-no later than 2045. "Hawaii lawmakers made history passing this legislation--not only for the islands, but for the planet," said Jeff Mikulina, Executive Director of the Blue Planet Foundation. The measure, if enacted by Governor David Ige, would make Hawaii the first state in the nation with such a 100% renewable energy standard. Blue Planet Foundation, whose mission is to clear the path for 100% renewable energy, praised the move. "Passage of this measure is a historic step towards a fossil fuel free Hawaii," said Mikulina. "This visionary policy is a promise to future generations that their lives will be powered not by climate-changing fossil fuel, but by clean, local, and sustainable sources of energy."
Bill Tucker for Forbes: Vortex Bladeless is a radical company. It wants to completely change the way we get energy from the wind. Think wind stick instead of a massive tower with blades that capture blowing winds. Wind stick. Really. Lest you think I’m mad, I’ve included a picture of this bladeless generator that helps with the visualization and explains the company name. See? There are no blades. What that “stick” (the company prefers, mast) does is capitalize on an effect of the wind which has been a very serious problem for architects and engineers for decades. When wind hits a structure and flows over its surfaces the flow changes and generates a cyclical pattern of vortices at the tail end of the flow. This is known as the vortex shedding effect which creates something known as vorticity and that is what Vortex Bladeless uses to generate energy. For those who need a explanation that exceeds my ability to fully explain, check out this link on Wikipedia and then come back and join the rest of us who won’t wait for you. (you’re clearly ahead of us anyway)
