It’s not difficult to remember the elemental symbol for hydrogen (H) or that it is the most common element in the universe. But what do you do when you’re an ambulance medic and the pile-up you’ve just pulled up at involves one of the GM Equinoxes that will take to the public roads this fall? This is the scenario that the Department of Energy would like to prepare first responders for with a new course, Introduction to Hydrogen Safety for First Responders, something the Hydrogen and Fuel Cell Safety organization is probably quite pleased to hear.

The DOE created the course with the Pacific Northwest National Laboratory and the Volpentest Hazardous Materials Management and Emergency Response (HAMMER) Training and Education Center. According to the DOE, “the course provides basic information to help raise awareness among fire, law enforcement, and emergency medical personnel and provides access to resources for more detailed information if needed.”

Basic understanding hydrogen and how it is stored and dispensed are two of the topics addressed in the course; videos and animations act as information carriers here. The course is available online, so if you want to test your skills (or are actually a first responder), check it out here.

Scientists from the National Oceanic & Atmospheric Administration’s (NOAA) Earth System Research Laboratory unveiled a new tool to monitor changes in atmospheric carbon dioxide and other greenhouse gases by region and source. The tool, called CarbonTracker (http://www.esrl.noaa.gov/gmd/ccgg/carbontracker), will enable its users to evaluate the effectiveness of their efforts to reduce or store carbon emissions, officials said on March 21.

The online data framework distinguishes between changes in the natural carbon cycle and those occurring in human-produced fossil fuel emissions. It also provides verification for scientists using computer models to project future climate change. Potential users include corporations, cities, states and nations assessing their efforts to reduce or store fossil fuel emissions around the world.

“NOAA encourages science that adds benefit to society and the environment. CarbonTracker does both,” said Conrad Lautenbacher, Ph.D., undersecretary of commerce for oceans and atmosphere and NOAA administrator. “Increasingly, observations of the Earth are demonstrating a remarkable impact on our understanding of human and natural systems. We are transitioning this understanding gained from intensive research into operations that benefit the environment and the economy.” (more…)

The electricity industry is changing. At least 50 percent of customers have the option to purchase renewable electricity directly from their power supplier. Such power is sometimes referred to as “green power” or “clean power.”

In most states, you can buy clean power through one or more of the following programs:

Green pricing — Some power companies are now providing an optional service, called green pricing, that allows customers to pay a small premium in exchange for electricity generated from clean, renewable (”green”) energy sources. The premium covers the increased costs incurred by the power provider (i.e. electric utility) when adding renewable energy to its power generation mix.

Competitive electricity markets — In some parts of the country, consumers can choose not only how their electricity is generated, but also who generates it. Just as the long-distance telephone industry was restructured, certain states have restructured their electricity industry in order to allow competition among electricity generators. In some of these states, clean power generators, who specialize in producing electricity using renewable sources, are taking advantage of the restructured market to sell clean power products to residential, commercial, and wholesale customers.

Some default suppliers are also teaming with these competitive marketers to offer more green power options. Efforts to sell clean power are aimed at consumers who will choose to pay slightly more for renewable energy products and services that reflect their environmental values. The small premium you pay offsets the additional costs power companies incur in purchasing and/or generating electricity from renewable sources.

Green certificates — Buying green certificates allows you to contribute to the generation of clean, renewable power even if you can’t buy clean power from your power provider (i.e. electric utility) or from a clean power generator on the competitive market.

An increasing number of clean power generators are now separating the power that they sell to power providers from the environmental attributes associated with that power. These environmental attributes, called green certificates (also known as “green tags,” “renewable energy certificates,” or “tradable renewable certificates”), are then sold to companies and individuals who want to help increase the amount of clean power entering the nation’s electricity supply.

By separating the environmental attributes from the power, clean power generators are able to sell the electricity they produce to power providers at a competitive market value. The additional revenue generated by the sale of the green certificates covers the above-market costs associated with producing power made from renewable energy sources. This extra revenue also encourages the development of additional renewable energy projects.

Several organizations offer green energy or renewable energy certificates that can be purchased separate from your current electricity service.
