There have been enough successful low-income solar pilot programs at the state and federal level that it is now possible to launch a larger initiative with confidence that it can succeed.
By Lucas Mearian, ComputerWorld: Renewable energy, combined with prolific battery storage, will soon result in vastly cheaper electricity -- and solar power that's less expensive than what fossil fuel-based power plants can produce. Additionally, solar power with lithium-ion and flow-battery storage systems will make the combination of renewable energy so inexpensive that it will surpass nuclear power and obviate the need for futuristic power sources such as fusion. That was consensus view from a several keynote speeches delivered at the Intersolar Conference in San Francisco this week. Eicke Weber, director of the Fraunhofer Institute for Solar Energy Systems, said that in sun-rich countries, the cost of solar power is already below 5 cents per kilowatt and it will continue to plummet as battery storage systems become more prolific and less expensive.

The use of a tracking system for a utility-scale project not only reduces LCOE, but also provides more usable power by broadening the power production curve to provide a smoother flow of energy from dawn to dusk.
PVWatts performs simplified PV system performance calculations using information about the arrays geographic location, orientation, and a set of user-input loss factors
By JASON DEAREN, Associated Press: On a vast tract of old North Carolina farmland, crews are getting ready to build something the South has never seen: a commercial-scale wind energy farm. The $600 million project by Spanish developer Iberdrola Renewables LLC will put 102 turbines on 22,000 acres near the coastal community of Elizabeth City, with plans to add about 50 more. Once up and running, it could generate about 204 megawatts, or enough electricity to power about 60,000 homes. It would be the first large onshore wind farm in a region with light, fluctuating winds that has long been a dead zone for wind power. After a years-long regulatory process that once looked to have doomed the plan, Iberdrola spokesman Paul Copleman told The Associated Press that construction is to begin in about a month. Right now, there's not a spark of electricity generated from wind in nine states across the Southeast from Arkansas to Florida, according to data from the American Wind Energy Association, an industry trade group. But taller towers and bigger turbines are unlocking new potential in the South, according to the U.S. Department of Energy, and the industry is already looking to invest. Cont'd...
From¬ Eagle Eye Power Solutions: The Eagle Eye¬ HGD-3000¬ Hydrogen Gas and Smoke Detector with (optional) Silent Intrusion Alarm is designed for unattended battery installations or remote shelters containing gassing lead acid batteries and charging systems... Lead-acid batteries on charge emit hydrogen gas after reaching the 80% recharge point. When mixed with enough air, hydrogen becomes a highly flammable gas that can ignite easily with just a spark, destroying equipment and harming personnel.¬ The lower explosive level (LEL) for hydrogen is 4.1% by volume.¬ Hydrogen Gas Detection Attach the HGD-3000 to the wall, ceiling, or optional junction box using the mounting holes at the top and bottom of the detector box. The HGD-3000 will turn on an exhaust fan when hydrogen gas levels reach 1% and will alarm at 2%. This alarm consists of a local 80db horn, a flashing red LED, and a dry contact switch closure for remote alarming. Smoke Detection The photoelectric smoke sensor detects minute combustion products from smoldering wire insulation, battery cases, and other material. When smoke is detected, a distinctive alarm is emitted from the 80db horn and a separate dry contact switch is activated. At this time, the exhaust fan is inhibited in order to deny the fire increased oxygen from outside air. Temperature, Loss of Power, & Intrusion During normal operation and in the absence of an alarm condition, an internal thermostat will turn on the exhaust fan at a preset temperature to reduce heat buildup in the room. Loss of power to the unit will also generate a dry contact alarm. Additionally, an optional infrared intrusion alarm will trigger a silent dry contact switch. Product website
Home energy storage helps whichever energy source is the cheapest, and helps the grid stay stable and available to us all.
Solar power was particularly efficient when combined with ground heat in terms of the profitability of investments.
A solar powered water system is one of the easiest solar power systems to install and will ultimately save you time and money.
The Obama administration on Tuesday announced an initiative to help low- and middle-income Americans gain access to solar energy, part of a series of steps President Obama is taking to tackle climate change, according to administration officials. The administration said it intends to triple the capacity of solar and other renewable energy systems it installs in federally subsidized housing by 2020, make it easier for homeowners to borrow money for solar improvements and start a nationwide program to help renters gain access to solar energy, the officials said. The actions were announced in Baltimore by Brian Deese, Mr. Obama’s senior adviser for climate issues, and Representative Elijah E. Cummings, the Democrat who represents the city. Mr. Deese, in a conference call with reporters, called the moves “part of a bigger-picture effort to try to drive innovation” toward cleaner, low-carbon energy solutions. Also unveiled on Tuesday were commitments totaling more than $520 million from charities, investors, states and cities to pay for solar and energy-efficiency projects for lower-income communities.

This is the "Strawberry bench". The solar-powered smart bench (yes, really) collects energy via a solar panel on its roof, and uses it to power a range of functions: monitoring air quality, disseminating information about the local area, offering free power-ups for the phones of passers-by. This summer, four of these benches will be installed around Canary Wharf, the privately-owned office and retail estate at the heart of London's Docklands. The concept was the winner of the "Cognicity Challenge", a competition intended to find innovative proposals to use technology to create smarter urban environments (and, as a side effect, make everyone feel all warm and fuzzy towards the Canary Wharf Group). The name, incidentally, has nothing to do with actual Strawberries. The company behind them is Belgrade-based Strawberry Energy, whose previous products include the "Strawberry Tree", a vaguely familiar solar-powered mobile phone charge and wifi hub with a bench attached to it. Both products were the work of architect Milos Miliojevic.
North Carolinas Renewable Energy Portfolio Standard (REPS) has encouraged investments in renewables and the energy economy statewide.
