Researchers from North Carolina State University have shown that Duckweed, a tiny aquatic plant much loved by Ducks can thrive in the effluent waste water produced by large feedlots, such as hog farming operations and potentially in urban sewage water as well. This hardworking little plant not only cleans the waste water of the excess nutrients, but in the process it produces large quantities of valuable starchy biomass. Biomas that can be harvested and used to produce ethonol in the same types of facilities that are currently being used to make ethanol from corn starch.
Smart meters, which are meters that are hooked up to a network so that they can deliver information about current usage in a timely manner, are rapidly becoming ubiquitous. Smart meters will enable real time energy decisions in response to current conditions. They form a critical cornerstone of the smart grid; in fact in many ways they are the “smart” in the smart grid. This opens up a whole slew of new opportunities for smart software developers and smart entrepreneurs [no pun intended] to build the software applications and services to support and to add value to these new smart networked grids. What kinds of software opportunities exist in this newly opening sector?
Senate Majority Leader Harry Reid (D-Nev.) has introduced legislation to support president Obama’s vision of a green grid. The Clean Renewable Energy and Economic Development Act will promote investments in transmission to facilitate access to renewable power, and also establish a streamlined planning and siting process for transmission lines. This legislation will make it easier for renewable energy suppliers to deliver clean energy from the often remote areas where it is harnessed to major population centers across the country.
After a run of some years of heady double digit growth the Solar PV sector in the US has hit a period of slower growth in which some of the weaker players are being shaken out of the market. This year will be characterized by consolidation as more successful firms and better capitalized firms build their market share and absorb weaker players. This shakeout was inevitable and is natural, but it was undoubtedly triggered by the financial crash of late 2008 coupled with the bursting of the oil futures speculative bubble and the temporary collapse in prices on the oil spot markets.
Many believe that the green economy will be powered by the wind and by the sun. But fewer people are aware that to make this possible we need to profoundly transform the current electric grid to control and manage renewable energy supplies. Balancing load and demand is a quite a challenge with renewable supplies that are intermittent and depend on the weather. Without a robust ability to continuously balance energy supply and demand, wind or solar energy sources can have a profoundly negative impact on grid operations, reliability and power quality and force grid operators to make costly and inefficient adaptations to current spot conditions.
Earlier this month, First Solar, Inc. (Nasdaq: FSLR) announced that it has reduced its manufacturing cost for solar modules in the fourth quarter 2009 to 98 cents per watt, becoming the first solar cell manufacturing company to break the $1 per watt price barrier. This is a major price milestone for the solar photovoltaic manufacturing sector and represents a significant step towards achieving what is known in the industry as as grid parity, the price level where the per watt cost for solar electricity reaches the current averaged cost of electricity on the grid a goal First Solar plans to reach by 2012.
In 2008 the US experienced an explosive rate of growth in installed wind power capacity. Last year the US added an additional 8,358 megawatts (MW) of new generating capacity (enough to serve over 2 million homes) surpassing Germany as the world’s largest producer of wind energy.
Interior Secretary Ken Salazar wants to create renewable energy zones to spur solar and wind energy projects, and build power lines to get the electricity to markets. In an interview with The Associated Press, Salazar said that while some regions of the country as well as offshore areas have great potential for wind energy and solar, there isn’t a clear plan to develop the resources.
Wacker Chemie AG will build a $1 billion plant in southeastern Tennessee that is estimated to create 500 green collar jobs in the region to manufacture hyperpure polycrystalline silicon, primary material used in the manufacture of solar panels. The company has purchased a 550-acre site about 30 miles northeast of Chattanooga. purchasing the site in Chattanooga will enable it to quickly build up its production capacity outside of the Euro zone in order to meet the projected growth in demand for solar cell feedstock in the US market.
