Interview with Michael Wiener of SolarRoofHook.com
In general, the installer just removes the roof piece, locates the rafters, drills pilot holes, fastens the product to the rafter, properly seals the penetration, and grinds the tile where the mount is located before placing the roof piece back over or around the mount.

After record year, U.S. energy storage forecasted to break 1 GW capacity mark in 2019
Peter Maloney for UtilityDive: The U.S. energy storage market put in a strong showing in 2015 with its “best quarter and best year of all time,” according to the GTM/ESA report. And current market trends point toward continued strong growth.
The recent extension of the federal Investment Tax Credit, and new guidelines under consideration at the Internal Revenue Service are expected to further boost energy storage and the pairing of storage with renewable resources.
In the fourth quarter alone, the U.S. deployed 112 MW of storage capacity, representing more than the total of all storage deployments in 2013 and 2014 combined.
For the full year, 221 MW (161 MWh) of storage was installed. In 2014 65 MW (86 MWh) of storage was installed in the U.S. Cont'd...

These Lego-Like Batteries Plug In To Store Solar Power At Home
Adele Peters for Co-Exist: Less than a year after Tesla unveiled its Powerwall battery for storing electricity at home, a startup has designed a much cheaper alternative that you can plug in yourself, without an electrician.
The modular batteries, called Orison, can be hung on the wall or set on the ground to double as an LED lamp. If you want more power, you just add the units together.
"Think of Orison like Legos," says co-founder and CEO Eric Clifton. "The 2.2 kilowatt-hour unit is really just one piece, so you can actually add as many as you need." The 2.2 kilowatt-hour version is as large as the company could make one unit and keep it under 40 pounds, so it could be easily shipped and moved.
With one unit, if your power went out in a storm, you could keep an energy-efficient refrigerator running for about two days. If you want to back up everything in your house, you'd connect a long series of batteries together.
For someone with solar panels on the roof, the batteries can store power to use at night. Right now, most people can sell extra solar power back to the grid when they're not using it, but many state laws are about to change so people will make less money. Batteries can help solar homeowners save money by making use of the power they've generated. Cont'd...
Offshore wind projects in United States see renewed interest
By PHILIP MARCELO for AP: The offshore wind industry has high hopes for establishing a permanent beachhead in the U.S. after years of disappointment.
Business leaders and politicians who gathered for an industry conference in Boston this week said wealthy investment firms and seasoned European offshore wind companies are increasingly committing to projects along the East Coast. That, they said, is evidence a domestic industry dreamed about for nearly two decades is finally on its way.
"There's a palpable sense that it's finally happening," said Bryan Martin, a managing director at D.E. Shaw & Co. That New York hedge fund is the principal backer of Deepwater Wind, a Rhode Island-based company looking to launch the country's first offshore wind farm off Block Island by the end of the year. "The U.S. tends to start small and ramp up very fast. I believe that will happen with offshore wind."
Among the significant new players to emerge in the past year is DONG Energy, a Danish firm that operates more than a dozen wind farms, including some of Europe's largest. Cont'd...
These 10 Places Broke Records In Renewable Energy
The following nations have, at one point or another, broken global records in renewable energy use, production or technology development.
Warren Buffett Downplays His Battle With Elon Musk in Nevada Over Solar Power
Joe Carmichael for Inverse: Buffett, in an interview with CNBC on Monday, responded to viewer questions about this clash (a clash that Bloomberg Business intensified with a cover story): two viewers asked why Buffett’s companies are preventing and deterring net metering in Nevada. Buffett responded:
“We don’t have a problem with net meters, and we’re the leading in renewables in the country among regulated utilities. The [unintelligible] we do not want our million-plus customers that do not have solar to be buying solar at 10 and a half cents when we can turn it out for them at 4 and a half cents or buy it at 4 and a half cents. So, we do not want the non-solar customers, of whom there are over a million, to be subsidizing the 17,000 solar customers. Now, solar customers are subsidized through the Federal Government — as we are, with our wind and solar operations ourselves. …
“In Nevada, [Musk's company, SolarCity] had an arrangement for a very limited number of people — and the public utility commission decides this — they had an arrangement where the utility had to pay way above market for solar produced by these 17,000 homes, and that —“
The interviewer interrupted to clarify: “For instance, if I have solar electricity that I’m producing, that’s more than I need, I can sell it back to you…” Cont'd...

Is the US undermining India's solar power programme?
Justin Rowlatt for BBC News: Whatever happened to all the talk of international co-operation to tackle climate change that we heard during the climate conference in Paris just a few months ago?
That is what many environmentalists are asking after the United States delivered a damaging blow to India's ambitious solar power programme this week.
In response to a US complaint, a World Trade Organization (WTO) panel has ruled that India's National Solar Mission breaches trade rules.
It judged that India's policies on buying locally made solar power equipment discriminates against imports.
"The ink is barely dry on the UN Paris Climate Agreement, but clearly trade still trumps real action on climate change," Sam Cossar-Gilbert of Friends of the Earth International said in a statement.
But is the decision really as damaging as many commentators seem to think?
Let's start at the beginning. Cont'd...
Here's How Electric Cars Will Cause the Next Oil Crisis
Tom Randal for Bloomberg Business: With all good technologies, there comes a time when buying the alternative no longer makes sense. Think smartphones in the past decade, color TVs in the 1970s, or even gasoline cars in the early 20th century. Predicting the timing of these shifts is difficult, but when it happens, the whole world changes.
It’s looking like the 2020s will be the decade of the electric car.
Battery prices fell 35 percent last year and are on a trajectory to make unsubsidized electric vehicles as affordable as their gasoline counterparts in the next six years, according to a new analysis of the electric-vehicle market by Bloomberg New Energy Finance (BNEF). That will be the start of a real mass-market liftoff for electric cars.
By 2040, long-range electric cars will cost less than $22,000 (in today’s dollars), according to the projections. Thirty-five percent of new cars worldwide will have a plug. Cont'd...
