Global Annual Installed Capacity of Small and Medium Wind Turbines is Expected to Exceed 446 MW in 2026

Despite weakening policy drivers and competition from declining solar PV prices, the SMWT industry is still poised for growth. With a large amount of wind resource potential still available, plus several growing and emerging markets, the industry is anticipated to sustain itself into the foreseeable future. Click to tweet: According to a new report from @NavigantRSRCH, the global installed capacity of SMWTs is expected to grow from 176.4 MW in 2017 to 446.0 MW in 2026.  "With historically leading markets such as the United States, the United Kingdom, and China seeing declining annual installed capacities of small and medium wind in recent years, other countries such as Japan, Denmark, and Italy are emerging as forces in the distributed wind market thanks to favorable government incentives," says Adam Wilson, research associate with Navigant Research. "We're also seeing a shift with medium-sized turbines as their niche slowly shrinks as drivers continue to favor small wind turbines for distributed wind and larger multi-megawatt turbines dominating utility-scale applications."   Full Press Release:

Stabilizing battery storage

Morgan Sherburne for U of Michigan News:  An issue that has long plagued renewable energy facilities is how to efficiently store energy collected from sun or wind. Now, University of Michigan and University of Utah chemists have developed an energy-storing molecule that is 1,000 times more stable than current compounds, potentially leading to a longer-lived, more efficient battery. The researchers are working to develop industrial-scale batteries that can store large amounts of energy for deployment when the sun sets or the wind stops blowing. Deep-cycle lead batteries or lithium ion batteries are already on the market, but each type presents challenges, including the significant environmental hazards of disposal. Also, these kinds of batteries wear out relatively quickly.   Cont'd...

How drones are helping design the solar power plants of the future

Katie Fehrenbacher for T he Guardian:    At the edge of a plot of muddy farmland, a few miles down the road from the University of California at Davis, an engineer takes a few quick steps across crop rows and lets go of a three-foot drone. Within seconds, the device - which weighs less than 2lbs and carries a powerful camera - ascends hundreds of feet into the cold, clear, blue sky and begins to snap detailed photos of the ground far below, including a long row of large solar panels mounted on steel poles. This flight is just a test, demonstrated by Kingsley Chen, the drone fleet coordinator for SunPower at the solar company's research and development center, which is under construction and about a two-hour drive northeast of the San Francisco Bay Area. The drone will enable SunPower to survey a wide region and help design a solar power farm that can fit more solar panels on a piece of land, more quickly and for lower costs than it previously could.   Con'td...

SDG&E Unveils World's Largest Lithium Ion Battery Energy Storage Facility

In response, SDG&E expedited ongoing negotiations and contracted with AES Energy Storage to build two projects for a total of 37.5 MW of lithium ion battery energy storage. In addition to the 30 MW facility built in Escondido, Calif., a smaller 7.5 MW installation was built in El Cajon.   Full Press Release:  

Follow the Patents: For Solar Power, the Devil Is in the Details

Alec Schibanoff for Electric Light & Power:  There actually is a crystal ball that permits you to see into the future. All you have to do is follow the patents. The latest patents in any technology will show you where that technology—and the businesses that use that technology—are going. This month, we take a look at the future of solar panel installation. The first solar power generator was displayed at the Universal Exposition in Paris in 1878. The first U.S. Patent for a solar power device was awarded the next year to Edward Weston. He actually received two patents: U.S. Patent No. 389,124 for an “Apparatus for Generating Solar Radiant Energy” and U.S. Patent No. 389,125 for the “Art of Utilizing Solar Radiant Energy.” It was not until 1954 that Bell Labs developed the first silicone-based solar panel.   Cont'd...

7,000 Railways Stations In India To Go Solar

Saurabh Mahapatra for CleanTechnica:  Almost every railway station in India will soon be fed with solar power if the plans announced in India’s latest union budget are implemented. The Indian Finance Minister Arun Jaitley announced that the 7,000 railway stations across the country will be fed with solar power as per the Indian Railways mission to implement 1,000 megawatts of solar power capacity. The minister made the announcement during the union budget speech on 1 February 2017. The minister stated that work to set up rooftop solar power systems at 300 stations has already started, and soon this number will increase to 2,000 stations. According to data released by the Minister of Railways, India had 7,137 railway stations at the end of March 2015. These rooftop solar power systems are expected to be implemented through developer mode, wherein the project developer will sign long-term power purchase agreement with Indian Railways.   Cont'd...

High-tech canopy helps generate solar power while providing shade

Barbara Eldredge for Curbed:  Imaginative architect and designer Carlo Ratti has had some bonkers ideas over the past year, including an exercise-powered gym barge and a mile-high skyscraper park. But his latest project is on the sunnier side of feasibility. Literally. The Sun&Shade is a light-reflecting canopy made of mirrors that automatically rotate to catch the sun’s rays and fling them at a photovoltaic panel, “located a safe distance away.” This generates clean electricity up top while cooling the shaded area beneath. A working prototype of the mirrored structure just debuted at Dubai’s Museum of the Future as part of its “Reimagining Climate Change.”   Cont'd...

Chinese solar company opening local module factory in September

Victor A. Patton for Sacramento Business Journal:  A solar module factory expected to bring more than 200 jobs to Sacramento is slated to begin production in mid-September at McClellan Business Park.  It will be the first U.S. factory for Nanjing, China-based solar cell and module manufacturer China Sunergy Co, who on Thursday announced its subsidiary Sunergy America has agreed to lease a 140,000-square-foot manufacturing building — previously a plant where J.C. Penney made window coverings. Simon Szeto, a Sunergy advisor, said the company will bring around 20 management staff from overseas and will hire other employees locally.  The work being done at the factory will include putting together the modules. Each module includes a solar cell, an aluminum frame, tempered glass, cables and a junction box. The completed products, which can be placed on a ground mount or rooftop, will be sold commercially in the U.S, Szeto said.  Cont'd...

Catch wave power in floating nets

Zhong Lin Wang for Nature:  Nature provides three sources of energy for free: sunlight, air and gravity. Solar and wind power are increasingly exploited, gravity less so. Hydraulic power plants harvest energy from flowing rivers. Tidal energy can be gathered along some inlets and coasts. But few places are suitable for dams or barrages, which can also damage the environment. By contrast, oceans cover about 70% of Earth’s surface. Wave energy is plentiful day and night, whatever the weather. Capturing it requires little land and raises few safety or security concerns. Yet hardly any of this ‘blue energy’ is being generated. Today’s wave farms produce no more than 1–10 megawatts at any one time, enough to power a town. No commercial wave farms currently exist.   Full article:  

First Wattway solar road pilot in US pops up in rural Georgia

Lacy Cooke for Inhabitat:  The first Wattway solar road pilot in America has popped up in rural west Georgia. The Ray C. Anderson Foundation, named for sustainable manufacturing pioneer Ray Anderson, is testing renewable technologies along an 18-mile stretch of road, and recently installed 538 square feet of Colas‘ Wattway solar road system near the border between Georgia and Alabama. Part of Georgia’s Interstate 85 was named for Anderson, but as over five million tons of carbon dioxideare emitted yearly on that road portion alone, Anderson’s family felt placing his name there didn’t honor his legacy, and began to look into renewable technologies to clear the air – so to speak. Thus began The Ray, an 18-mile living laboratory for clean technologies, including not only the solar roads, but also a solar-powered electric vehicle charging station, and WheelRight, a system people can drive over to test their tire pressure, which could lead to improved fuel inefficiency.   Cont'd...

Record-breaking solar panels could slash power costs

Reuters Jim Drury:  Swiss start-up Insolight says its solar panels double the yield achieved by other sun-powered technology. In independent tests the panels reached an efficiency of 36.4 percent. "Traditionally the market sits at around 18 percent and we can double this. Therefore we can double the return on investment for the final client....Our key innovation is that you do not need to rotate the panel in order to follow the sun. We can follow the sun in a flat manner, like any other solar panel, which makes it that our panel can be installed on standard rooftops, with standard mounting technology." Tiny square super cells capture all of the sun's rays, underneath round lenses, using a patented microtracking system.   Watch Video.

Smart Meters and Utilities

Smart meter deployments are the most common smart grid (or smart utility) activity. Utilities are also adding sensors into their networks to better understand operating conditions.

China is now the largest producer of solar power in the world

Lacy Cooke  for Inhabitat:  One way China is working to battle climate change-causing carbon emissions is by developing a vast army of renewable energy projects. Even as the country struggles with pollution, it has made great strides on clean energy. They’re now the largest producer of solar energy by capacity in the world, adding 34.54 gigawatts of the country’s installed capacity of 77.42 gigawatts last year alone. The country’s National Energy Administration (NEA) announced over the weekend that in 2016, installed photovoltaic capacity in China more than doubled. Their data revealed the jump to 77.42 gigawatts after the country added 34.54 gigawatts. The provinces in which capacity increased most include Shandong, Henan, and Xinjiang, which is also one of the provinces with the largest overall capacity. Gansu, Inner Mongolia, and Qinghai join Xinjiang in that latter category.   Cont'd...
