Solar is very hot at the moment. A list of cleantech stock picks for 2014 has First Solar (a solar manufacturer) and SolarCity (a solar installer) at Nos. 1 and 2, respectively, and further down the list are a solar holding company, Renewable Energy Trade Board, and a solar equipment company, Meyer Burger.
There are many reports, including one on another site that I write for on occasion TriplePundit, that the solar market is heading for a “second gold rush” this year; there’s little to dispute the fact that solar is definitely an in thing, especially for investors. Read the rest of this entry »
When it comes to renewable energy and efficiency, a double-dip in the dish is a great deal.
The latest in solar dish technology that does what solar installations do—converts sunlight into power—but with an added twist: it generates clean water.
The efficiency of the typical solar installation ranges from 10 to 20 percent, with the rest waste heat. Swiss researchers associated with IBM have developed the High Concentration PhotoVoltaic Thermal system (HCPVT), which uses that waste solar heat to generate fresh water.
It’s reminiscent of the ancient craft of turning lead into gold. But it’s not alchemy, it’s real. Read the rest of this entry »
Reports of the solar industry’s pending demise have been greatly exaggerated, at least according to research by McKinsey.
According to the consultancy, the solar-power industry is merely suffering from “growing pains.” The article, “Solar power: Darkest before dawn,” dispels the notion that the industry has “lapsed into a classic cycle of boom and bust after a decade of unprecedented growth” even though that might appear to be what’s happening.

The show lays out the current status of climate change and what is doable on an individual and global basis. For example energy efficiency, while certainly not the total answer, will help tremendously. Take a look at the carbon footprint of the average U.S. family in a year–some 50 tons of CO2!
Remarkably, while there’s no glossing over that what we’ve done to the planet is alarming and dangerous and getting more so — the show has an upbeat and even optimistic message. It’s a solvable crisis because we have the technology and innovative ideas; we need the will for change.
This is really neat but will using solar power to create fuel have long-term legs? We’ll see – at some point alternative, renewal fuel ideas will have to catch on, won’t they?
Anyway this one is called solar biomass gasification, a concept and process that’s been around for some time, mostly in university scientific research circles. A relatively new company that has emerged from that university research environment, Sundrop Fuels Inc., might have the drop on making a commercial go of it.
CEO Wayne Simmons puts it quite succinctly: “We’re going to convert the sun’s energy into liquid fuel using concentrated solar power to gasify biomass, then convert the resulting syngas into green gasoline or diesel.”
The idea of the Solar power satellite is the yin to the yang of the Ronald Reagan’s expensive 1980s Star Wars fantasy, and almost as old. Scientists for decades have explored the potential of using space-based solar cells to beam power to the Earth.
Now the Japan Aerospace Exploration Agency (JAXA) has gone beyond whimsy by actually signing up several major collaborators to launch a giant one-gigawatt space solar power satellite into space. The players are huge – Fujitsu, Mitsubishi Electric and Sharp – and the bucks that JAXA has indicated it will invest in the project are also massive, $21 billion worth.
Warehouses and distribution facilities may be emptier inside than usual these days, but the rooftop space above is a great and largely untapped solar energy resource.
Distribution facility developer ProLogis, which was hard-hit last year by the collapse of the real estate industry, is on the cutting edge of what could and should be a bright business and sustanability opportunity in the logistics and warehousing arena.
The Denver company has formed a Global Renewable Energy Group that will oversee the procurement, development and management of new eco-friendly properties while providing management services for renewable energy projects, including a major push to provide rooftop space for solar energy installations.
One of the group’s first management efforts was announced recently: A new, 4.8-megawatt (MW) solar project that will be installed on eight rooftops at the ProLogis Park Sant Boi in Barcelona and ProLogis Park Alcala in Madrid, Spain. It’s a co-development arrangement with San Francisco’s Recurrent Energy that also marks Recurrent’s first foray into Europe.
