France’s green artistic panache

with one comment


img_5446Leave it to the French to make something as mundane as a wind turbine into a work of art by installing two of them on the Eiffel Tower.

Yes, that Eiffel Tower, which itself is a monument to both creativity and sustainability: when it was built in 1889 it was only intended to last for 20 years. In the ensuing 126 years the tower has gone through many renovations, but the latest sends a decidedly green message whirling into the future.

Earlier this year, the renewable energy firm Urban Green Energy installed two wind turbines inside the metal scaffolding of the tower. The turbines will produce 10,000 kilowatt hours, enough to power the tower’s first floor commercial establishments, which include restaurants, a souvenir shop, and exhibits about the history of the tower.

The turbines are part of a plan to reduce the environmental impact of the tower. Société d’Exploitation de la Tour Eiffel (SETE), the organization that runs the tower, is also installing rainwater collection systems, LED lights, and solar panels on it. Read the rest of this entry »

Solar heat

with 2 comments


solar energy_Mike RaySolar 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 »

Next Silicon War: how governments affect business practices

with one comment


solar panelsThis is a guest post by Liz Nelson from WhiteFence.com. She is a freelance writer and blogger from Houston. Questions and comments can be sent to: liznelson17@gmail.com.

Thanks in large part to the support the Chinese government has offered to manufacturing, cheap solar panels flooded the global market causing a great deal of damage to renewable energy businesses. The damage was fueled by subsidies from the Chinese government that allowed manufacturers to sell solar panels for less than actual cost, thus allowing these manufacturers to dominate the market and put many foreign developers out of business.

Dishing up some solar energy alchemy

with one comment


solar-dishWhen 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 »

Huge drop in solar costs on the way

leave a comment »


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.

Earth Day viewing: Nova’s Power Surge

leave a comment »


PBS’ production of Power Surge, aired on Nova Wednesday night, is an excellent companion as we settle in for Earth Day musings and strategies.

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.

A solar ‘sledgehammer’ to produce biomass gas

with 2 comments


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.”
