Nanocrystals could boost photovoltaic solar energy technologies
(01/04/2006) Los Alamos National Laboratory scientists have discovered that a phenomenon called carrier multiplication, in which semiconductor nanocrystals respond to photons by producing multiple electrons, is applicable to a broader array of materials that previously thought.
Russia's folly, an opportunity for renewable energy?
(01/03/2006) With its willingness to use energy as a political instrument, Russia has provided the world with further incentive to pursue renewable energy. The Kremlin has shown it cannot be counted upon as a reliable source of energy and western markets should see this as an opportunity to take a long, thoughtful look at energy security and re-evaluate the benefits of developing renewable energy technologies.
Businesses can now host solar energy project without up-front costs
(12/21/2005) 3 Phases Energy Services announced today its launch of a new service, "Daylight Savings", a model for financing large-scale solar photovoltaic (PV) projects. Daylight Savings allows businesses and institutions to host onsite photovoltaic systems while eliminating all up-front capital requirements and providing a long-term hedge against fossil fuel prices.
Scandinavians mix sea and river water to generate electricity
(12/19/2005) Two Scandinavian groups have invented devices that generate electricity by mixing sea and river water. The technologies work based on the difference in salt concentration between ocean water and freshwater.
Making wind power less deadly for birds
(12/15/2005) High oil prices and concern over climate change are driving interest in renewable energy technologies. All types of potential power sources -- not limited to the sun, ocean tides and waves, raw sewage, and even insects -- are the focus of media reports, while governments and industry scramble to announce their grand plans for adopting green energy.
California plans $3 billion for solar energy projects
(12/13/2005) Tuesday the California Public Utilities Commission announced an ambitious program to expand the market for solar power, proposing to provide $2.8 billion of incentives toward solar development over the next 11 years.
Disposable solar panels developed using nanotechnology
(11/20/2005) Scientists at the University of Cape Town are exploiting the nano-scale properties of silicon to develop a super-thin disposable solar panel poster which they hope could offer rural dwellers a cheap, alternative source of power.
Solar projects in California desert could help state's energy problems
(11/17/2005) Two large solar projects in the desert of California could boost industrial-scale development of solar technology according to an article in today's edition of The Wall Street Journal.
Photovoltaic solar energy conversion can be cost-competitive by 2030
(11/16/2005) Professor Andrew Blakers from The Centre for Sustainable Energy Systems at the Australian National University will today report to the Greenhouse 2000 Conference in Melbourne that photovoltaic (PV) solar energy conversion can be cost-competitive with any low-emission electricity generation technology by 2030.
Renewable energy supplier becomes first to win EPA and DOE awards
(10/31/2005) Using innovation to drive market demand for renewable energy, 3 Phases Energy proved its leadership in the renewable energy industry at the 10th National Green Power Marketing Conference in Austin, TX held October 24-26. The Industry recognized 3 Phases Energy with two awards from the U.S. Environmental Protection Agency and Department of Energy: Renewable Energy Technology Supplier of the Year for general excellence supplying renewable energy, and Green Power Beacon, for the company's ability to originate business sector interest in renewable energy. In the history of the awards, no single renewable energy supplier has been recognized with two awards in the same year.
Organic solar cells will help spur viability of alternative energy
(10/10/2005) Organic solar cells being developed by a team of scientists from New Mexico State University and Wake Forest University could help spur viability of alternative energy. Unlike existing solar panels made of brittle silicon, these cells are made of plastic that can be wrapped around structures or even applied like paint. This flexibility could revolutionize the solar market.
Biofuels threaten rainforests as important European Commission decision lies ahead
(10/01/2005) To meet Kyoto protocol commitments, various European and other governments are encouraging the use of biomass as fuel (biofuel) in transport and electricity. Biofuels are mostly carbon neutral, and switching from fossil fuels to biodiesel is promoted as a solution to climate change.
High oil prices make Asia pursue green energy
(09/09/2005) For energy-hungry Asian governments, the answer could literally be blowing in the wind. Across the region, renewable energy such as solar, wind and geothermal power is gaining ever greater credence as a way to curb the region's appetite for oil and cut runaway import bills.
China to add wind power capacity
(08/15/2005) China plans to construct its first offshore wind power complex next year in hopes of easing chronic electricity shortages, the official Xinhua News Agency reported Monday.
Cow manure + sunlight + metal ore = hydrogen fuel?
(08/11/2005) Researchers led by Michael Epstein at the Weizmann Institute of Science in Israel think they may have an energy efficient way of collecting solar energy to generate hydrogen, a key input for fuel cells.
Renewable energy in China, a strategic future?
(08/02/2005) China's failed bid for American petroleum firm Unocal may prompt it to further focus on its development of alternative energy sources.
China announces wave power station changes
(07/27/2005) China announced that it has developed typhoon-resistant technologies for the world's first experimental wave power station. The announcement comes two months after a Norwegian firm signed an agreement to construct a commercial wave farm to harvest electricity from sea swells off the coast of Scottland.
How might I buy invest in green energy projects?
(07/20/2005) On June 17, Associate Press reported that Zilhka Renewable Energy hopes to complete a $100 million wind farm in eastern Oregon by December 2006. The article said the company owned wind farms in eleven states. For many investors, green or otherwise, this would seem like a great company in which to own stock. Whether or not the numbers would bear that out, a savvy investor would first want to know, "How might I buy a piece of Zilhka or invest in their projects?"
