Matt Ridley, the UK author, journalist and member of the House of Lords, recently asserted in a Wall Street Journal article that the “world’s resources aren’t running out.” Well maybe, sorta. If you are into the mental gymnastics of conservative doublethink.
I could not let his piece pass without providing, shall we say, a different and more intellectually honest (I hope) viewpoint.
He asks: “How many times have you heard that we humans are ‘using up’ the world’s resources, ‘running out’ of oil, ‘reaching the limits’ of the atmosphere’s capacity to cope with pollution or ‘approaching the carrying capacity’ of the land’s ability to support a greater population? The assumption behind all such statements is that there is a fixed amount of stuff—metals, oil, clean air, land—and that we risk exhausting it through our consumption.” Read the rest of this entry »
Recently I wrote about Boeing’s all-electric satellite, which might launch later this year. Not to be outdone, apparently, Airbus Group flew the first all-electric aircraft late last month, called the E-Fan.
The E-Fan is an all-electric trainer aircraft made of composite material.
Leaving jet fuel behind means there is slight hitch: at the moment the the plane can fly for about an hour on a single charge. In any case this is a pretty big deal, because the largest aerospace and defense company in Europe and the world’s leading commercial aircraft manufacturer is backing it, is planning to build the trainer in series and is also planning to use what it learns to eventually develop a regional passenger model.

All-electric satellite propulsion is getting a boost from Boeing, which says it is “on track” to deliver the world’s first all-electric xenon-ion propulsion satellites in late 2014 or early 2015 after meeting key production milestones on its initial 702SP (small platform) satellites.
Boeing announced that it has completed static qualification testing, verification and assembly of the primary structures for 702SP inaugural customers ABS and Eutelsat, meaning the satellites are well on their way to launch. The initial contract for the satellite was signed in 2012 between Boeing and Satmex. Eutelsat acquired Satmex in January 2014.
The four 702SP communications satellites will launch in pairs, and once in orbit, they will be entirely powered and propelled by electricity, rather than relying on rockets. The first two are scheduled for launch aboard a single SpaceX Falcon 9 rocket early next year. An all-electric satellite dispenses with heavy chemical propulsion and uses electric propulsion not only to maintain itself stably in orbit over 15 years, but also to raise the satellite from where it is dropped into orbit by its carrier rocket to its final destination in geostationary orbit.

The nation’s first offshore wind farm on the Pacific Coast cleared a crucial federal hurdle when Seattle’s Principle Power received approval to move forward on a commercial lease for the proposed $200 million, 30 Mw project.
Principle Power received the go-ahead last month from a Department of the Interior agency to lease 15 square miles of federal waters 18 miles from Coos Bay, Oregon. If the lease request gets final approval, the WindFloat Pacific project would anchor the first offshore turbines in federal waters on the West Coast. It also would be the first in the nation to use triangular floating platforms instead of single piles driven into the ocean floor. Read the rest of this entry »
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 »
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.

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 »
