Renewable energy shows an average price decline over the last 5 years of 78% for utility scale solar and 58% for wind. Lazard, an asset management firm, has a fascinating new analysis of renewable and other energy prices out. There are a huge number of insights in this, from an outside analyst whose primary interest is financial. […]
High Concentration PhotoVoltaic Thermal (HCPVT) A cutting-edge solar system that resembles a 10-meter-high sunflower has just been unveiled by IBM Research and Swiss solar technology company Airlight Energy. The High Concentration PhotoVoltaic Thermal (HCPVT) system can concentrate the sun’s radiation 2,000 times and convert 80 percent of it into useful energy, generating up to 12 kilowatts of electrical power and […]
Tesla/SpaceX chief and sustainable energy champion, Elon Musk, has finalized plans to build a 1.2 million square-foot megafactory in Buffalo, NY through his company SolarCity. The factory targets to create enough solar panels a year to harness a gigawatt of the sun’s energy.
Panther Vision Powercap When you go out into the darkness then you’d better be prepared with a good durable flashlight to light up your path. However, packing an extra flashlight may sometimes make your gear a bit heavy which can slow you down.
Inexpensive renewable sources will provide more energy than the world needs in less than 20 years. Leading consultants were skeptical about cellular phones in the 1980′s. McKinsey & Co. noted that the handsets were heavy, batteries didn’t last long, coverage was patchy, and the cost per minute was exorbitant. It predicted that in 20 years the total […]
We have been talking about how much solar panels increase the value of your home for years. We use a simple calculation to determine the increase in value: We add the energy savings you’ll see per year for 20 years. Well, it looks like we’re not just blowing solar smoke; study after study after study comparing sales of solar and non-solar […]
Wildpoldsried produces 500% more energy than it needs. Wildpoldsried, Germany, a Bavarian village of about 2,600 residents, is leading the way in Germany’s extraordinary renewable energy transformation. The village has invested in a holistic range of renewable energy projects over the past 17 years that include 4,983 kWp of photovoltaics, five biogas facilities, 11 wind turbines and a hydropower system. As a result, the village […]
By the late 2020s or early 2030s renewables could be competing much more aggressively with the oil market. Kepler Chevreux, a French investment bank, has produced a fascinating analysis that has dramatic implications for the global oil industry. The investment bank estimates that $100 billion invested in either wind energy or solar energy – and […]
Solar cell printers. We’ve come a long way from the solar-powered calculator to waiting to see when innovators are going to give us solar-powered smartphones, where most of our calculators are these days. While the average energy consumer is busy worrying about such everyday concerns, scientists at the Victorian Organic Solar Cell Consortium (VICOSC) are wondering how to […]
