Though some people already seem inseparable from their smartphones, even more convenient, wearable, solar-powered electronics could be on the way soon, woven into clothing fibers or incorporated into watchbands. This novel battery development, which could usher in a new era of "wearable electronics," is the topic of a paper in the ACS journal Nano Letters. Current wearable electronics, such as smartwatches and Google Glass, still require a charger with a
Bio-based solar cell developed by the researchers in Germany by embedding the two proteins photosystem 1 and 2, which in plants are responsible of photosynthesis, into complex molecules developed in-house, thus creating an efficient electron current. In leaves, the photosystems 1 and 2 utilise light energy very efficiently; this is required for converting carbon dioxide into oxygen and biomass. The Bochum researchers' bio-based solar cell, on the other hand, generates
According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's Office of Energy Projects, solar, biomass, and wind "units" provided 694 MW of new electrical generating capacity last month or 99.3% of all new generation placed in-service (the balance of 5 MW was provided by oil.) Twelve new solar units accounted for 504 MW or 72.1% of all new electrical generating capacity in October 2013 followed
China's increase in renewable energy is on course to surpass the European Union, the United States and Japan combined, says the International Energy Agency. In its annual World Energy Outlook released Tuesday, the IEA said China will be the strongest driver in the worldwide trend in which renewable energy is expected to account for almost half of the increase in global power generation by 2035, China Daily reports.

The use of solar panels to produce hot water is standard practice, but researchers at the Madrid Universities Carlos III and Politecnica suggest that they may also be used to provide large offices with heating in the winter and AC in the summer. Their proposal involves the incorporation of solar collectors into a gas-based cogeneration system with an absorption machine, which would reduce both energy expenditure and carbon dioxide emissions.
Solar farms are a no-brainer in warm and sunny places, but what about in northern climes where snow can cover and even shut down the panels? Michigan Technological University's Keweenaw Research Center (KRC) is now part of a 2-year study that will help answer that question. The aims are to gauge how snow affects solar panels' power generation and determine the best ways to overcome any losses. The international engineering
Harvard Business School has just completed a large rooftop solar installation using AC modules from ET Solar powered by SolarBridge microinverters. Massachusetts-based solar energy company Solect Energy Development, LLC installed the 80kW project at Tata Hall, a new executive education facility. The Tata Hall project addresses Harvard University's commitment to reduce greenhouse gases thirty percent by 2016 using 2006 as a baseline and including all future growth. Read
Small robotic birds could be useful for tasks such as environmental monitoring and conducting surveillance. But the major drawback they have is the amount of time they are able to stay aloft. Because of the birds' light weight and small size, the tiny batteries used to power them deplete in just minutes. University of Maryland Professors S.K. Gupta and Hugh Bruck and their students in the Maryland Robotics Center are working
A new report from IHS Inc. forecasts that global photovoltaic installations will rise at the fastest pace in 3 years in 2014, exceeding 40 GW for this first time and generating installation revenue of more than $86 billion. Annual solar installations are predicted to reach 41 GW in 2014, firmly marking the end of the solar sector’s two-year slowdown. IHS stands by its earlier prediction that installations this year will amount to 35 GW.
With $7 billion on the table, the Army has been procuring a lot of renewable energy lately. The latest announcement comes from the Army’s Energy Initiatives Task Force and the US Army Corps of Engineers, which jointly selected 13 biomass vendors to compete for future orders. This is the 4th selection of vendors in recent months from the geothermal, solar, and wind industry, and is an important policy implementation step
