Describes a new efficiency milestone that has been achieved by quantum dot solar cells, a kind of solar PV that uses the unique properties of quantum dots to capture photons and convert their energy into an electric current. This form of solar PV has languished for some time due to the low efficiencies that have been so far achieved. By finding a way to produce a double layer cell the research team at the University of Toronto has been able to achieve significantly higher overall efficiencies than has previously been possible using quantum dot technology. Quantum dot technology holds the promise of being able to ultimately produce very inexpensive solar cells, if the low efficiency problem can be overcome.
A detailed review of 12 U.S. based synthetic biology, biofuel & biochemical companies that are developing third and fourth generation biofuels, bioindustrial & household chemical, and food additive products; using synthetic biology to produce engineered microorganisms and specialty enzymatic products. Each company is examined in turn, looking at its financials and the uniqueness and strength of its processes and technology as well as at any important partnerships or alliances that have been formed.
Examines the subtleties of electric vehicle charging cycles, and the interactions with smart grid variable pricing, and the user’s own varying usage scenarios.
Solar power continues along its firmly established downward cost curve and edges ever closer to achieving the historic milestone of grid parity. Today it just got a huge boost that will help it scale out in this country and will go a long way towards tipping the long term balance in favor of solar. In fact as the industry achieves scale it is cutting per unit costs down. This post outlines the announcement of a large DOE initiative to promote rooftop direct grid connected solar power in the US.
The Energy Efficiency and Renewable Energy agency (EERE) has announced a roadmap workshop for enhanced geothermal. It is inviting a select — small — group of subject matter experts to take part in this roadmap workshop in order to help develop a plan for how the country can proceed in developing its dry rock geothermal resources and enhancing existing geothermal resources.
The solar sector is among the most hated on Wall Street. Many names in the solar sector that are heavily shorted, in spite of it being the fastest growing energy sector in the U.S. Meanwhile, the world is using oil faster than it’s being pumped, which is economically dangerous, because oil price spikes have preceded all recessions since 1970. More renewables could serve to lessen our ridiculous economic vulnerability to oil prices.
Greenstart, a startup accelerator exclusively designed for cleantech companies, is seeking applications for the company’s inaugural three-month accelerator session, which begins on September 12. Submissions will be accepted until July 3
Consumer behavior is pushing buyers to reject green products. The majority of consumers believe that the prices are high, the products are inferior, and being green is feminine. Consumers want green products that emphasize the benefits of their use more than their environmental appeal and they want them at the same quality and price as mainstream products.
This post looks at the pressing issues of electronic waste and at the environmental and financial costs of recycling this growing mountain of obsolete computers, displays and peripherals. It suggests that a wider adoption of reverse logistics more generally in the electronics industry may help to manage the end of life process. This is a growing problem, even though the size of electronics keeps shrinking the sheer volumes continue to grow as these devices become ever more ubiquitous.
