According to the US Geological Survey, 66% of public water comes from surface water. Presumably some of that is pumped at some point, but even if only half of that were gravity fed, the potential for electricity production from municipal water pipes is significant.
Deterministic weather forecasts have their place, but probabilistic forecasts are the clear choice for alternative energy companies that take the weather seriously and need long-term data.
WattJoule Corporation, a developer of next-generation liquid electrical energy storage systems, has developed and built a new system demonstrating a major industry cost breakthrough. The new storage platform is called ElectriStor™ and will be offered to system integrators as the preferred core component for storing large amounts of solar and wind energy. One of the major barriers preventing the widespread adoption of large-scale energy storage has been cost. WattJoule has engineered the ElectriStor™ platform based on the redox flow battery concept where electricity is stored in a liquid. WattJoule's proprietary liquid electrolyte is mostly water, and the company has developed a new, inexpensive process to make it in large quantities. Early liquid energy storage systems have suffered from a number of technical and cost limitations. Recently there have been several technical breakthroughs to overcome these constraints. WattJoule has both developed and exclusively licensed key technologies that, in combination, dramatically lower energy storage costs to $150 per kilowatt-hour in its first-generation energy storage product.

And while lithium has traditionally been controlled by a handful of major global suppliers, spiking demand is changing this landscape drastically.
Brady Dennis for The Washington Post: The U.S. wind energy industry had a memorable 2015, from installing thousands of new turbines across the country to supporting a growing number of jobs. But perhaps one of the most noteworthy brights spots of the past year, according to an annual report released Tuesday by the American Wind Energy Association (AWEA), was the growing demand for wind energy from major corporations. High-tech firms such as Google Energy, Facebook and Amazon Web Services, as well as more traditional companies such as Procter & Gamble, General Motors, Walmart and Dow Chemical, have signed contracts to purchase increasing amounts of wind energy in coming years. Corporations and other non-utility customers — including some municipalities and universities — accounted for more than half of the wind power capacity sold through so-called power purchase agreements in 2015, according to the AWEA. The group said that corporate and other non-utility buyers have signed contracts for more than 4,500 megawatts of wind power capacity, or enough to power the equivalent of about 1.2 million American homes.

Ian Clover for PV Magazine: A study by EuPD Research shows just 34% of PV installers in the U.S. offer storage solutions to customers, with those reluctant to do so citing cost concerns. However, 26% that currently do not offer storage hope to include it in their portfolios this year. For all the glitzy product launches by the likes of Tesla and Sonnen, the solar+storage landscape of the U.S. is still largely shaped by what leading installers are – or aren’t – prepared to offer to customers, and a recent survey has found that around two-thirds do not currently include storage technology in their product portfolio. EuPD Research’s latest PV Installer Survey USA 2015/16 revealed that only one-third of installers already offer energy storage to homeowners or businesses in the U.S. looking to adopt solar power. Of the two-thirds that do not, 38% said that current pricing of batteries impedes demand, meaning margins are too low for installers and the "technological maturity" of the systems on the market is not currently convincing. However, the mood does appear to be shifting in favor of storage, with 26% of survey participants saying they hope to add storage products to their portfolio at some stage in 2016. Cont'd...
Universal access to renewably-generated electricity could be within the foreseeable future, with cleaner air and water as the side effects. Better public transportation systems will make life more enjoyable for commuters all over the country, as will a self-sustaining energy economy.
Sam Grobart for Bloomberg: There are 332,519,000 cubic miles of water on the planet. That's 352,670,000,000,000,000,000 gallons just sloshing around out there. Anyone who's ridden or been tossed by a wave has a sense of the kinetic energy contained in our perpetually moving oceans. If we could harness it, it could provide a clean, renewable source of energy. But efforts to turn our oceans into power generators—often in the form of "aqua-mills," windmill technology adapted to water—have foundered on the complexity of their many moving parts in the corrosive and remote environs of the sea. A new approach, developed by a company called Oscilla Power, applies all that kinetic energy to a solid piece of metal instead of using it to turn the blades of an impeller. That creates an alternating magnetic polarity in the metal that can be converted into electrical current. Oscilla's technology, which is nearly solid-state, may prove far more durable than any other ocean-power project, increasing the chance to draw power from our oceans cleanly, meaningfully, and endlessly.

Solar Energy Index Underperforms S&P in Q1 2016
In 2015, the ethanol share of gasoline was 9.9%, and the biodiesel share of distillate was 2.4%.
In September 2015 SunGift Energy completed the UK's first 'solar carports' on the top decks of two multi-storey car parks.
Adam Vaughan for The Guardian: The amount of household solar power capacity installed in the past two months has plummeted by three quarters following the government’s cuts to subsidies, according to new figures. A fall in solar power was expected following a 65% reduction in government incentives paid to householders, but the size of the drop-off will dismay green campaigners who want take up on clean energy sources to accelerate. Data published by the energy regulator this week shows there was 21 megawatts (MW) of small solar installed in February and March this year, after a new, lower incentive rate came into effect. By contrast, energy department figures show that for the same period in 2015, 81MW was installed. Cont'd...
From North American WindPower: According to MAKE’s latest wind power outlook for North America, unprecedented long-term policy certainty in the U.S., along with a new climate-conscious government in Canada, will enable nearly 75 GW of total wind power growth in the region from 2016 to 2025. The production tax credit (PTC) in the U.S. was extended in December 2015 as a multiyear phaseout and will support a total of 44.4 GW of wind power additions from 2016 to 2021. However, as the value of the PTC phases down after 2018, several drivers must align to sustain wind power growth in the U.S. At the sub-regional level, Texas will lead wind power growth from 2016 to 2018, followed by the Plains and the Midwest. Turbine technology advancement and balance-of-plant cost reductions will continue to drive down the levelized cost of electricity (LCOE) of wind power and offset a portion of the lost PTC value from 2019. This will allow wind power to maintain a substantial share of new power generation demand, despite attractive costs for natural gas power and rising competition from solar photovoltaics. Last year, the U.S. alone added nearly 8.6 GW of new wind energy generation. Cont'd...

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
