Three Simple (and Effective) Strategies for Solar Lead Generation
Don't get overwhelmed at the prospect of launching a solar lead generation program: if you focus on the basics, you'll have a great foundation for finding new customers.
Batteries Need to Get Big-Like, Enormous-for Solar Power to Shine
Vaclav Smil for IEEE Spectrum: It would be a lot easier to expand our use of solar and wind energy if we had better ways to store the large quantities of electricity we’d need to cover gaps in the flow of that energy.
Even in sunny Los Angeles, a typical house roofed with enough photovoltaic panels to meet its average needs would still face daily shortfalls of up to about 80 percent of the demand in January and daily surpluses of up to 65 percent in May. You can take such a house off the grid only by installing a voluminous and expensive assembly of lithium-ion batteries. But even a small national grid—one handling 10 to 30 gigawatts—could rely entirely on intermittent sources only if it had gigawatt-scale storage capable of working for many hours.
Since 2007, more than half of humanity has lived in urban areas, and by 2050 more than 6.3 billion people will live [PDF] in cities, accounting for two-thirds of the global population, with a rising share in megacities of more than 10 million people. Cont'd...
Energy Storage Market and Trends
Adding backup power provides a tremendous value to the customers in certain areas with unreliable grid. In combination with other values, this is a trend that is producing a very strong demand - stronger than we initially thought.

U.S. wind power enjoys a rebirth as solar's obstacles mount
Nichola Groom for Reuters: A year after Congress extended generous tax credits for renewable energy projects, the U.S. wind industry is thriving.
Solar power companies, meanwhile, are hunkering down for a rough 2017.
The tax credit renewal has boosted the long-term outlooks for both industries. But in the short term, the subsidies are far more attractive for wind power, which has spurred utilities to launch wind projects while they scale back or delay solar installations.
Advances in wind turbine technology are also opening up new locations for development and driving a wave of spending to upgrade existing projects.
In the last few weeks, power companies with large renewable holdings - including Southern Co, NextEra Energy Inc and Xcel Energy Inc - have announced plans to invest billions of dollars in wind.
"We're making a pivot now away from solar," Southern Chief Executive Tom Fanning told a meeting with Wall Street analysts in October. Cont'd...
Science Plant a Wind Tree in your neighborhood to generate energy from low-speed wind
Bruce Brown for Digital Trends: These trees do more than just add ambiance. Harnessing the wind to generate electrical energy usually brings to mind thoughts of huge land- or ocean-based wind farms consisting of huge towers with two or three blades, each more than 100-feet long, on the top. The size, weight, noise, and vibration of industrial wind turbines restrict their use to large open spaces. Newwind, a French startup, has developed a much smaller, urban-space-friendly “Wind Tree,” reports Electrek.
The Wind Tree, which produces sufficient energy to power small buildings or streetlights, is designed to connect to a nearby energy storage system. The trees are each about 30 feet tall and 26 feet in diameter, and weigh approximately 5,500 pounds. Each tree has 54 Aeroleafs mounted vertically on tree branches. The Aeroleafs are 3.2 feet high and, spinning at optimum speed, are capable of generating 65 watts each. So, a tree with 54 leaves has an energy-generation capacity maximum of 3,510 watts (3.5kW), about the same as a small home solar installation. Cont'd...
How to Manage Snow on Solar
The snow melting on your panels actually acts as a lubricant between the snow mass and the panel surface, which makes the solar panel a completely frictionless, slick surface thats the perfect candidate to allow that snow mass to come barreling off your roof.
The Solar Industry Has Paid Off Its Carbon Debts
Robinson Meyer for The Atlantic: Think of all the energy that goes into making a single solar panel. Quartz and copper must be mined. The raw materials must be converted into wafers, then encased in protective material. And after panels leave the factory, they must be shipped all over the world.
Now imagine these consequences spread over four decades—the environmental cost of the solar industry. Given all the research, development, and production time that goes into making any one panel, a skeptical solar-buyer might wonder: Has the solar industry on the whole really saved any energy at all? To that concern, a new analysis answers: Yes.
The solar industry probably paid off its long-term energy and climate “debts” in 2011, a study published this week in Nature Communications finds. Cont'd...
Small Power, Big Grid: Part 5
The Emerging Relationship between Distributed Energy Resources and the Transmission System
Nearly half of residential distributed solar power is owned by private companies
Lucas Mearian for ComputerWorld: About 44% of all solar power that's installed on residential rooftops, known as distributed solar capacity, is owned by private businesses, such as SolarCity or Vivint Solar, according to new government data.
Distributed solar capacity in the U.S., which includes all solar power capacity other than utility-scale installations 1 megawatts (MW) or larger, increased to 12.3 gigawatts (GW) as of September, according to new figures from the Energy Information Administration (EIA). In comparison, a cumulative 11.6GW had been installed in the U.S. by the end of 2015. Cont'd...
Glow-in-the-dark dye could fuel liquid-based batteries
Charlotte Hsu for University of Buffalo: BUFFALO, N.Y. — Could a glow-in-the-dark dye be the next advancement in energy storage technology? Scientists at the University at Buffalo think so.
They have identified a fluorescent dye called BODIPY as an ideal material for stockpiling energy in rechargeable, liquid-based batteries that could one day power cars and homes. BODIPY — short for boron-dipyrromethene — shines brightly in the dark under a black light.
But the traits that facilitate energy storage are less visible. According to new research, the dye has unusual chemical properties that enable it to excel at two key tasks: storing electrons and participating in electron transfer. Batteries must perform these functions to save and deliver energy, and BODIPY is very good at them. In experiments, a BODIPY-based test battery operated efficiently and with longevity, running well after researchers drained and recharged it 100 times. Cont'd...
