Green Options

San Diego Gas & Electric has embarked on a demonstration project to test the commercial viability of a new concentrated solar power system that uses shallow pools of water as a passive cooling system for high-efficiency solar cells.  The unique proprietary technology was developed by Pyron Solar of Sorrento Valley, California.

The new technology could be attractive in land-rich areas, and it may also have some application for introducing sustainable energy to more densely developed areas, since its use of high efficiency solar cells enables it to pack more generating capacity into less space.  It also may prompt some new exploration of the opportunity to double up solar energy generation with other operations, such as fish farming.

John Rowe, Exelon CEO, said yesterday that climate change legislation is an urgent issue. At the same time, he announced that the nation’s largest utility would not be renewing its membership with the US Chamber of Commerce because of the Chamber of Commerce’s opposition to climate legislation.

Tested on the California/Nevada border, the Ecotricity Greenbird broke the land speed record for wind-powered vehicles.  The Greenbird clocked in at a top speed of 126.4 mph and maintained a speed of 126.2 mph for three seconds.  The previous record was 116mph.

The Greenbird is a collaboration between Ecotricity and engineer Richard Jenkins.  Ecotricity is an independent green electricity company based in the UK founded and owned by entrepreneur Dale
Vince.  Jenkins is the founder of the Windjet project and has a wide range of skills in engineering, design, piloting, and construction experience.  Both sides are innovative, experienced, and have a passion for wind energy as a solution for transportation and utilities.

Meeting energy needs while being efficient and using environmentally responsible technologies is probably the single greatest change that needs to happen to alter the effects of climate change now. In the United States and the European Union, governments are backing smart grid and renewable energy programs. Undoubtedly, the two technologies go hand-in-hand, but where should we put our efforts (and dollars/euros) first?

The current Russia/Ukraine gas crisis is moving British gas companies to sell British gas supplies overseas, thereby keeping prices high and hitting UK consumers directly. Is is time for the UK to take political and economic control of their energy supply and run the industry for the public good and not for overseas profit?

Power utilities in India would now be required to buy a set percent of total energy from renewable energy sources but the government must also look to solve the primary problems like environmental clearance & infrastructure.

Greenbox is working on giving us web-based tools to evaluate our energy usage in the home, and to understand that usage in greater context with those around us, too. Users can also use that information to pinpoint savings opportunities and to understand our footprints on the planet.

Greenbox offers this food for thought:

“If 30% of us reduced our electricity usage by 20%, we would save over $8 billion per year

GreenSmith Energy Management Systems has unveiled technology it claims can solve the peak demand issues experienced by U.S. utilities.

The company has created a battery control-management system, that when paired with a lithium ion battery, can store up to 20 kilowatt-hours. The system can then deliver a full 4,000 discharge cycles.

More and more utility companies in Georgia are turning to biomass calling it a clean, renewable resource. Oglethorpe Power Corporation in Tucker, GA is planning three 100 megawatt biomass-fueled power plants. Back in April, Georgia Power sought approval from the Georgia Public Service Commission to convert a coal-fueled power plant to biomass. Utilities are touting biomass [...]

The Solar Electric Power Association (SEPA) has outlined four easy steps to a thirty fold increase in the size of the US solar power industry between 2009 and 2016, leading to over $230 billion worth of investment and the creation of 440,000 permanent jobs.

According to an article in the latest bulletin from the Canadian Institute of Mining, Metallurgy and Petroleum, Prairie Mines & Royalty, Ltd. (PMRL) and Norit Canada are building Canada’s first activated carbon plant. This plant will manufacture activated carbon for a mainly Canadian audience of coal-fired power utilities.

PMRL is a subsidiary company of Sherrit International, the largest producer of thermal coal in Canada (about 90% of total Canadian coal production volume). Additionally, 90% of Sherrit’s coal is sold to nearby power plants located at what are called the “mine-mouth”. Norit on the other hand, is the world’s largest manufacturer of activated carbon and has been in the industry for over 80 years.

It’s fairly obvious why it makes sense for a joint venture building an activated carbon production plant between these two companies, but why build an this type of plant now?
