Cloud Computing Saves Energy and CO2 Emissions
Research firm Verdantix has released a study finding that companies that switch to cloud computing can save money on energy bills and reduce energy consumption. The study, sponsored by AT&T, estimates that cloud computing can save $12.3 billion on corporate energy bills and reduce carbon emissions by 85.7 million metric tons per year by 2020.
Pike Research released a similar report in 2010 concluding that cloud computing can reduce 38 percent of world datacenter energy use by 2020. Microsoft, Accenture and WSP Environment and Energy also deduced in a study released last year that cloud computing could cut carbon emissions by 30 percent for large efficient companies, and up to 90 percent for small less-efficient companies.

However, other studies have shown that while some aspects of cloud computing indeed save energy, others do not. The biggest culprit is data storage in the cloud. Unfortunately, Tucker’s research has found that the higher the storage load in the cloud, and the more often files are accessed and downloaded, the more energy intensive the cloud becomes.
When taking these studies into consideration, it is important to recognize the bias that may have driven the findings. After all, AT&T and Microsoft both offer cloud computing services, hence the unequivocal promotion of the cloud as an energy efficient alternative to in-house servers. However, when considering the total energy cost of servers, including mining the materials they’re made of out of the ground, manufacturing them, and transporting them, then centralized cloud servers probably do come out on top in reducing energy consumption.
Itronics successfully tests manganese recovery process
Itronics - a Nevada-based emerging cleantech materials growth company that manufacturers fertilisers and produces silver - has successfully tested two proprietary processes that recover manganese, with one process recovering manganese, potassium and zinc from paste produced by processing non-rechargeable alkaline batteries. The second recovers manganese via the company’s Rock Kleen Technology.
Manganese, one of the four most important industrial metals and widely used by the steel industry, has been designated by the US Federal Government as a "critical mineral." It is a major component of non-rechargeable alkaline batteries, one of the largest battery categories sold globally.
The use of manganese in EV batteries is increasing as EV battery technology is shifting to use of more nickel and manganese in battery formulations. But according to the US Department of Interior, there is no mine production of manganese in the United States. As such, Itronics is using its Rock Kleen Technology to test metal recoverability from mine tailings obtained from a former silver mine in western Nevada that has a high manganese content.
In a statement, Itronics says that its Rock Kleen process recovers silver, manganese, zinc, copper, lead and nickel. The company says that it has calculated – based on laboratory test results – that if a Rock Kleen tailings process is put into commercial production, the former mine site would become the only primary manganese producer in the United States.
Itronics adds that it has also tested non-rechargeable alkaline battery paste recovered by a large domestic battery recycling company to determine if it could use one of its hydrometallurgical processes to solubilize the manganese, potassium, and zinc contained in the paste. This testing was successful, and Itronics was able to produce material useable in two of its fertilisers, it says.
"We believe that the chemistry of the two recovery processes would lend itself to electrochemical recovery of the manganese, zinc, and other metals. At this time electrochemical recovery has been tested for zinc and copper,” says Dr John Whitney, Itronics president.
“Itronics has been reviewing procedures for electrochemical recovery of manganese and plans to move this technology forward when it is appropriate to do so and has acquired electro-winning equipment needed to do that.
"Because of the two described proprietary technologies, Itronics is positioned to become a domestic manganese producer on a large scale to satisfy domestic demand. The actual manganese products have not yet been defined, except for use in the Company's GOLD'n GRO Multi-Nutrient Fertilisers. However, the Company believes that it will be able to produce chemical manganese products as well as electrochemical products," he adds.
Itronics’ research and development plant is located in Reno, about 40 miles west of the Tesla giga-factory. Its planned cleantech materials campus, which will be located approximately 40 miles south of the Tesla factory, would be the location where the manganese products would be produced.
Panasonic is operating one of the world's largest EV battery factories at the Tesla location. However, Tesla and other companies have announced that EV battery technology is shifting to use of nickel-manganese batteries. Itronics is positioned and located to become a Nevada-0based supplier of manganese products for battery manufacturing as its manganese recovery technologies are advanced, the company states.
A long-term objective for Itronics is to become a leading producer of high purity metals, including the U.S. critical metals manganese and tin, using the Company's breakthrough hydrometallurgy, pyrometallurgy, and electrochemical technologies. ‘Additionally, Itronics is strategically positioned with its portfolio of "Zero Waste Energy Saving Technologies" to help solve the recently declared emergency need for domestic production of Critical Minerals from materials located at mine sites,’ the statement continues.
The Company's growth forecast centers upon its 10-year business plan designed to integrate its Zero Waste Energy Saving Technologies and to grow annual sales from $2 million in 2019, to $113 million in 2025.
