The Japanese architectural and engineering firm, Shimizu, has a solution for the climate crisis: Simply build a band of solar panels 400 kilometers (249 miles) wide running all the way around the Moon’s 11,000-kilometer (6,835 mile) equator and beam the carbon-free energy back to Earth in the form of microwaves, which are converted into electricity at ground [...]

SpiderFab 3-D robotic printer Since the 1970′s, space-based solar power has been a futuristic fantasy but the advent of 21st century 3-D printing may bring it a step closer to reality. (Video)
Homeowners who aimed their panels toward the west, instead of the south, generated 2% more electricity over the course of a day. Solar panels should face in the general direction of the sun. You would think that would be easy to do. But most installers of solar panels, especially the ones for homes, follow conventional [...]
Off-grid solar The off-grid clean energy market is booming. Sub-Saharan Africa is seeing 300 percent compound annual growth in off-grid lighting; Bangladesh is putting up 30,000 to 40,000 solar home systems every month; and d.light, a for-profit seller of solar lights, recently reached its1 millionth customer.

Solar power is a great way to keep robots running indefinitely, in theory. And it’s absolutely possible to do it, provided your robot doesn’t need to do anything urgently, you have a ludicrously powerful light source, or your robot is very efficient and spends a lot of time in the sun. That last category has potential for solar [...]
The U.S. has massive renewable energy potential. Transmission lines hold much of the same challenge and promise of the interstate highway system a century ago. The transmission network – the high voltage, long distance power lines that carry electricity from power facilities and into communities – is currently a patchwork system, lacking centralized organization or planning. [...]
31 percent of South Australia’s total energy came from renewable sources in 2012 and 2013. In South Australia, one in five houses already has a rooftop solar array. Twenty-seven percent of that region’s power is derived from wind energy. New figures released by the Australian Energy Market Operator (AEMO) predict that thanks to new sources of wind and solar power [...]
Solar panels on a rooftop in Yiwu, in China’s Zhejiang Province. From the last quarter of 2010 until the first quarter of 2013, leading Chinese solar companies were able to drop the cost of manufacturing multi-crystalline solar modules by 54 percent.
The solar industry employs nearly 120,000 Americans. Solar energy is hot. With a foundation of consistent, long-term deployment policies at both the federal and state levels, solar PV in the U.S. is leading an unparalleled price decline on the strength of enduring high demand from U.S. consumers.
Stella, solar-powered family car. Eindhoven University of Technology students have unveiled what they claim to be the world’s first solar-powered family car. The vehicle is called Stella and it resembles a squashed, wingless airplane. The vehicle can seat four people and can travel up to 600 kilometers, powered by solar panels mounted on the roof. [...]
