Unsubsidized wind and solar now the cheapest source for new electric power

Lucas Mearian for Computer World: Between 2015 and 2021, China is expected to install 40% of all worldwide wind energy and 36% of all solar

Power Regulation and Pitch Control

Wind gusts can increase wind speeds at rates and for durations just long enough for the energy to enter the system, but sometimes too fast for conventional pitch control systems to respond adequately.

Lunar-Based Solar Power Concept Could Solve The World's Energy Crisis

Wall Street Pit: If the moon can be turned into a solar power station, our energy problems for sustainable and affordable electric power on a global scale will be solved.

India Gets Record Low Bid to Build Solar Power, Minister Says

Anindya Upadhyay for Bloomberg: The price of solar power in India fell to a record low of 3.15 rupees (5 U.S. cents) a kilowatt-hour in a competitive tender where French firm Engie SA's local arm won rights to develop 250 megawatts.

Eon plots airborne wind route

Renews: Eon is collaborating with Dutch company Ampyx Power to develop the latter's airborne wind energy system. The agreement aims to further the development of the system towards commercial deployment.

Sneak Preview of Solar Decathlon 2017 Houses

Solar Decathlon 2017 takes place in Denver, Colorado, at the 61st & Peña Station October 5-9 and October 12-15, 2017.

Permanent Green Energy Production

All terrestrial energy sources except nuclear, geothermal and tidal are from current solar insolation or from fossil remains of plant and animal life that relied directly and indirectly upon sunlight, respectively.

This solar panel produces up to 5 liters of drinking water per day from the air

Derek Markham for TreeHugger: Zero Mass Water's Source device is a rooftop solar device that produces water instead of just electricity.

Tesla Just Unveiled Its Newest Solar Panels

Futurism: Tesla just updated their website to include images of their new low-profile solar panels. The panels integrate seamlessly with the Tesla Powerwall and can be ordered this month for production in the summer.

Wind turbine maker Vestas looks at expanding into energy storage

Reuters: Denmark's Vestas, the world's largest wind turbine maker, is keen to expand into areas such as energy storage to increase the global use of wind power and bring costs down.

Flower-shaped solar panel follows the sun

Megan Barber for Curbed: Based off the concept of how a sunflower follows the sun, the Smartflower is a portable, adjustable petal system that tracks the sun's path throughout the day. When the sun rises in the morning, the Smartflower automatically unfolds and begins producing energy by setting its petals at a ninety-degree angle. The flower goes "back to sleep" into a folding position at night or whenever high winds make it unsafe to operate.

Low-cost 'solar absorber' promising for future power plants

Emil Venere for Phys.org: Researchers have shown how to modify commercially available silicon wafers into a structure that efficiently absorbs solar energy and withstands the high temperatures needed for "concentrated solar power" plants that might run up to 24 hours a day.

The Growing Importance of Global-scale Renewable Energy

IEC provides a framework to test and certify renewable energy technology.

The World's Biggest Solar Energy Storage Farm Is Set to Launch in Australia

David Nield for Science Alert: Construction will soon be underway on a gigantic solar farm in South Australia that's set to be the biggest of its kind in the world - thanks to 3.4 million solar panels and 1.1 million individual batteries. The project is expected to be completed by the end of the year, at which point the huge plant should outdo all other solar farms in terms of overall battery capacity - although other solar facilities are larger in terms of land area.

NREL Publishes Landmark Residential Solar PV + Energy Storage Cost Breakdown

Joshua S Hill for CleanTechnica: The US National Renewable Energy Laboratory has published a landmark report extensively detailing component and system-level cost breakdowns for residential PV solar systems equipped with energy storage. The decreasing cost of solar systems has been well documented over the last several years, with increased innovation and decreasing manufacturing costs combining to make solar PV a competitive and economic choice for residents and utilities across the United States, and in fact the world. As such, the costs attributed to the development of residential and utility-scale solar projects has been well defined for some time - even though that figure keeps decreasing.
