Solar energy is not the only sustainable resource Cool Idea! Award winners have harnessed thus far.
From Benzinga: Global Equities Research analyst Trip Chowdhry has revealed some interesting information about Tesla Motors Inc 's new product line. Outside of the fact that it will not be a car, very little is known about what Tesla plans to announce. Some experts think it could be a motorcycle. Others assume that it will be an in-home battery that involves solar energy. If Chowdhry's information is correct, it seems that Tesla is ready to launch the latter. In a note to investors, Chowdhry said that he knows of two people that own a residential battery from Tesla. He spoke to one of those owners and detailed the following bullet points: "There are about 230 Households in California, who currently have Tesla Stationary Battery installed in their Homes. Another about 100 Households are out of California. This customer had the Tesla Stationary Battery for about One and a Half years, and is installed in his garage." Last year, Chowdhry attended a sustainability conference and learned that Google Inc is "widely believed" to have a few Tesla (commercial-grade) batteries in some of its buildings. Apple Inc. might also purchase some of these batteries for its new campus. Chowdhry believes that Tesla's commercial-grade batteries are rated at more than 400 kWh.
The East Coast of the U.S. experienced up to 5% lower than average levels of solar irradiance in 2014, negatively impacting overall performance of solar sites in the region. Concurrently, the West Coast enjoyed irradiance levels up to 10% higher than average, widening the productivity gap between projects in the country's two areas of highest solar development. This disparity is clearly seen in the 2014 Solar Performance Maps of the United States, released today by Vaisala, a global leader in environmental and industrial measurement. While it is well-established that the solar resource of the East does not match that of the West, the Atlantic Coast has a large volume of operational capacity and it is therefore of critical importance for project operators in the region to understand the reasons behind below average energy output and whether it is due to malfunctioning equipment or weather variability. Vaisala's 2014 study illustrates the impact of short-term, month-to-month weather variations on performance at U.S. solar projects and places them into a long-term context. This reveals frequent and significant deviations from long-term average irradiance conditions and highlights the clear requirement to analyze the effect of solar resource variability on both over and underperformance. From an annual perspective, this year's weather patterns had an adverse effect on a large number of installations along the Atlantic Coast from Florida to Massachusetts, as well as Texas, while the bulk of projects in California and the Southwest saw an uptick in solar irradiance that may have increased overall 2014 production at many sites. However, these annual variations only offer a high-level view of project performance. Vaisala also conducted a monthly analysis that gives a much more robust understanding of how specific weather conditions affected solar production throughout the year.
Catherine Shu for TechCrunch: Solar panels are becoming increasingly affordable, but many people still face barriers to harnessing the power of the sun for their own homes. For example, they might live in an apartment or in a house where the roof is angled or structured improperly for solar panel installation. A new Boston-based startup called CloudSolar is offering an intriguing solution. Founded by a team including two electrical engineering Ph.D. candidates and currently raising funds on Indiegogo, CloudSolar lets people buy a solar panel, or a share in one, on a farm that is expected to be completed by 2016 (erecting the solar panels will only take a couple of months, but the company also has to deal with utility and land permits, which will take longer). Once the farm is up and operating, electricity generated by the solar panels will be sold to local utilities. Solar panel owners are promised 80 percent of the total proceeds created by the panels over the next 25 years, and help with applying for whatever tax credits they are eligible for. They can monitor how much energy their panel is producing, and how much carbon dioxide emissions it is estimated to offset, through an app.
Eric Wesoff for GreenTech Media: Energy storage is a small market experiencing fierce growth. The U.S. installed 61.9 megawatts of energy storage in 2014, and GTM Research is forecasting 220 megawatts to be installed in 2015. But, as with the U.S. solar industry, energy storage projects are clustered in states with incentives or in regions where markets are able to place a value on storage. So it's no surprise that California, Hawaii, and New York have assumed early leadership in energy storage by virtue of their unique incentives, mandates and markets, according to the inaugural GTM Research and Energy Storage Association U.S. Energy Storage Monitor report.

The engineers at Ubiquitous Energy are developing solar panels that are completely transparent and as thin as a laminate. They can do this by creating see-through solar cells that absorb only the invisible parts of the solar spectrum—ultraviolet and infrared radiation. The technology still has a way to go because the cells must become more efficient to prove cost-effective, but their promise is big: solar cells that could become a part of any glass or plastic surface. They could sit, invisibly, atop a smartphone’s display, allowing the phone to charge itself under natural or artificial light. And if the process became part of glass and window manufacturing, homes and skyscrapers could draw power from the sun without the spatial and aesthetic limits of current, opaque solar panels.
The energy storage market is poised for substantial growth over the next five years, with installed capacity this year expected to more than triple to 220 MW from last year’s 62 MW. A recent report from GTM Research and the Energy Storage Association, ‘U.S. Energy Storage Monitor,’ projected that the market will grow from $128 million last year to $1.5 billion by 2019, when more than 800 MW will be installed. Moreover, non-utility storage – residential and non-residential – will grow from just 10% of installed capacity last year to 45% over the same period. This is a bullish forecast for downstream residential vendors identified in the report, such as Schneider Electric, Outback Power, Sunverge, and Solar City.
Friday's solar eclipse highlights the importance of energy storage to the continued growth of solar, experts have claimed. Energy consultancy Frost & Sullivan estimate that by covering 85% of the sun; the eclipse removed 35GW of solar power from the European grid - equivalent to 80 conventional power plants. This sort of instability will drive generators to invest in better storage facilities to ensure a constant security of supply, according to the consultants. "Dealing with events like this one requires investment in various storage tools and monitoring techniques which create a certain amount of flexibility in the energy system," said the report. The nascent technology of pump storage - pumping water uphill into large reservoirs when power is abundant and then letting it flow down again to generate power when needed - will reportedly be valuable in preparing for the eclipse in Germany.
Christopher Martin for Bloomberg: A Texas city just north of Austin plans to begin weaning its residents from fossil fuels. The municipal utility in Georgetown, with about 50,000 residents, will get all of its power from renewable resources when SunEdison Inc. completes 150 megawatts of solar farms in West Texas next year. The change was announced Wednesday. It will be the first city to completely embrace clean power in the state, which is the biggest U.S. producer and user of natural gas. More will follow as municipalities seek to insulate themselves from unpredictable prices for fossil fuels, said Paul Gaynor, SunEdison’s executive vice president of North America. Burlington, Vermont, made a similar move with its purchase of a hydroelectric plant last year. “This will be the first of many,” Gaynor said in a telephone interview. “The city is making a judgment that they want to enjoy a stable electricity price.”
From Tereza Pultarova for E&T Magazine: Japanese engineering giant Mitsubishi has successfully demonstrated wireless power transmission over a larger distance paving the way for harvesting energy in outer space. During the test at Mitsubishi Heavy Industries’ Kobe Shipyard & Machinery Works facility near Osaka, the engineers managed to beam 10kW of power through a microwave transmitter across a 500m distance. As the beam of microwaves hit the receiver and got converted back into energy, its LED lights turned on using the received power. Mitsubishi said the test ‘marks a new milestone’ in terms of both, the distance and power load, and verifies the firm’s space solar power systems (SSPS) concept. Mitsubishi envisions SSPS will take solar energy generation to an entirely new level. Solar panels would be placed at geostationary satellites, which hang above a fixed spot above the Earth’s surface at the distance of 36,000km, and unhindered by Earth’s atmosphere would generate energy much more efficiently. The wireless transmission system, freeing energy generation from the reliance on cables and wires, would then beam the energy to Earth using a microwave or laser technology. Mitsubishi believes space-based solar power will revolutionise renewable energy generation and will in future become the world’s number one source of clean renewable power.

The Environmental Governance approach of Osaka is exemplary for the developing Asian cities who are trying to balance development and sustainability.
By Andrew Freedman for Mashable: The partial solar eclipse slated to take place throughout Europe on March 20 may delight skywatchers, but it's presenting a significant headache for the operators of Germany's electricity grid. The country is a world leader in solar energy, boasting a huge edge over the U.S. in installed solar power generation. When the eclipse occurs between about 9:30 a.m. and 12 p.m., local time, on the 20th, electric utilities in Germany will have to contend with rapid swings in energy production. First, there will be a steep drop-off in generation, followed by a sudden spike. These fluctuations, and how utilities choose to cope with them, provide a preview of what utilities in the U.S. and other nations face, as renewable energy production soars in coming decades, according to an analysis from Opower, a software company that uses data to help utilities improve the customer experience. Germany gets about 7% of its electricity each year from solar panels, compared to 0.5% in the U.S., according to Barry Fischer, a writer and analyst at Opower. On the sunniest days, Germany can meet half of its electricity demand through solar power alone, he told Mashable in an interview.
