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...

Offshore wind energy system combines sea water and wind to create electricity

Megan Treacy for TreeHugger:  We've seen our share of interesting wind power designs, but often the technology can't come anywhere close to matching what the traditional horizontal axis wind turbines can do. There's a reason that when we think of wind energy, we think of giant masts with rotating blades and it's because that design is incredibly effective -- just look at Scotland and other areas around the world that now get a majority of their electricity needs from wind power.

The design isn't without its flaws; those rotating blades do pose a hazard to birds and bats and the cost of manufacturing and installing all of those giant parts can be expensive. When it comes to offshore wind power in the U.S., that has been a major roadblock. The energy generation potential is huge, but so is the cost.

An energy start-up company called Accio Energy -- yes, a Harry Potter reference -- thinks it has a solution to that problem, one that will generate as much if not more energy from offshore wind than a traditional wind turbine, but at half the cost. There are no moving parts, instead Accio's technology consists of large permeable panels on masts that let the ocean winds blow right through.  Cont'd...

The World's Largest Solar Plant Is Now Online in India

Avery Thompson for Popular Mechanics:  The world's largest solar power plant has just been completed in Kamuthi, in Tamil Nadu, India. The new plant adds 648 MW to the country's generating capacity.

The Kamuthi Solar Power Project takes the title of world's largest solar plant from the Topaz Solar Farm in California, which was completed two years ago and has a capacity of 550 MW.

The Kamuthi Solar Power Project was built in only 8 months, and cost $679 million to complete. It contains 2.5 million individual solar panels, covers an area of almost 4 square miles, and is expected to power 150,000 homes.  Cont'd...

Tesla powers a whole island with solar to show off its energy chops

James Vincent for The Verge:  Tesla completed its $2.6 billion acquisition of SolarCity this week, and, to celebrate, the company has announced a major solar energy project: wiring up the whole island of Ta’u in American Samoa. Previously, the island ran on diesel generators, but over the past year Tesla has installed a microgrid of solar energy panels and batteries that will supply "nearly 100 percent" of power needs for Ta’u’s 600 residents.

The project seems intended to show off the potential benefits of the SolarCity acquisition, with Ta’u’s microgrid comprised of 5,328 solar panels from SolarCity and Tesla, along with 60 Tesla Powerpacks batteries for storage. But buying SolarCity remains a risky move for Tesla, with the purchase including billions of dollars of debt for a company that's far from profitable (SolarCity spends $6 for every $1 it makes in sales). Nevertheless, Tesla CEO Elon Musk describes the acquisition as "blindingly obvious" — a necessary step in his so-called "Master Plan" to integrate clean energy generation and storage.  Cont'd...

Integrated Energy Systems

Opportunities for solar installers to offer storage as an integral part of their solutions are opening up everywhere, from mitigating the impact of power outages, the increase in distributed renewable generation at times of low use, the rising costs of base and peak power and the trend of some states to reduce or eliminate net metering programs.

Power to the people: Solar panel sales to soon surpass leasing

Lucas Mearian for ComputerWorld:  Direct ownership of solar power panels will overtake third-party ownership next year as more consumers are choosing to buy, rather than lease, their panels.

According to GTM Research's latest report, U.S. Residential Solar Financing 2016-2021, 55% of all U.S. residential solar capacity installed in 2017 will be purchased by customers paying either in cash, or through a solar loan financing arrangement; that number is expected to grow to 73% of all solar systems installed in 2021.  Cont'd...

Want to boost wind and solar power? Bring them together

Ben Jervey for GreenBiz:  What’s keeping solar and wind power from fully taking over the electric grid? For starters, the sun only shines during the day. Wind blows intermittently, is seasonally variable, and is not always blowing when the energy is needed.

But what if solar and wind work together?  "Wind resource tends to complement solar resource," said Sarah Kurtz of the U.S. Department of Energy’s National Renewable Energy Laboratory. "Here in Colorado, for instance, the windiest time is during the winter and spring months. In winter, we don’t have as much sunshine, but we tend to get more wind and stronger wind."

A handful of enterprising renewable energy developers are exploring how solar and wind might better work together, developing hybrid solar-wind projects to take advantage of the power-generating strengths of each — with the two technologies in tandem serving as a better replacement for climate-warming fossil fuels than either could be alone.  Cont'd...

Economics Trumps Policy: Even President Trump Cannot Stop the Renewable Energy Juggernaut

The renewable and energy efficiency industries have created over 2.5 million jobs in the United States. Solar now employs more Americans than than oil, natural gas and coal combined. The nation's fastest growing occupation is, believe it or not, the wind turbine technician; which is still projected to grow 108% in the next 7 years.

Renewed Interest from Traditional Investors in Renewable Energy

Renewables have now reached such a critical mass, utilities can no longer ignore them as a way to augment their capabilities in producing power cheaper, smarter, better. At this point, the tide has turned for utilities and there is no going back.
