How's that biofuel thingy workin' for ya?

It's great to be able to say that you are burning biofuel in the freight industry. It's another thing to prove a reduction in pollutants and greenhouse gases.

This is especially critical in shipping. According to a March 26, 2010 Coast Guard Compass article, the International Maritime Organization (IMO) announced a 200-mile Emission Control Area (ECA) around all U.S. coastlines. This new standard sets limits of particulates, nitros oxides, and sulfur oxides.

The problem for ships entering this zone is how to prove compliance. It's great that you have algae fuel in your tanks when inspected, but that still doesn't answer the question of what you were pumping into the atmosphere when you were in the ECA.

WR Systems developed a successful answer, Emsys. This system continuously monitors stack gases records the levels and time/location using GPS. Reports can be submitted in standard or custom formats electronically. At the same time, Maersk Line Limited has been contracted by the U.S. Navy to conduct at-sea tests of marine-grade biofuel. The shipping line has turned to WR Systems to install Emsys for timely and accurate monitoring.

No Room on the Roof? How About a Community Solar Garden?

There is a growing trend among those frustrated homeowners who don't have adequate roof space or their roof is facing the wrong direction to take advantage of solar power. It's called a community solar garden.

Home Power Magazine published an article in their June - July 2011 issue that discusses this interesting option. In those states where the laws are favorable, people in the same community can form their own LLC (Limited Liability Corporation) and build a solar array that can provide energy for sale back to the local power company. Members receive credit towards their utility bill in proportion to their investment.

One thing that is very attractive is there is no need to modify any wiring or metering in any of the members' homes. When a member decides to move and sell his or her house, the membership can be sold simultaneously. The new buyer may be able to roll that investment into the mortgage as a part of the value of the home.

Changing Critters in Biofuel

Fox News recently reported on a Massachusetts firm that shows great promise in delivering high-quality and high-volume diesel fuel using water and carbon dioxide. So what's different between this process and algae fuel? The difference is which "critter" is chosen to produce the fuel. Joule Unlimited is using genetically engineered bacteria instead of the more traditional algae to produce bio-diesel.

The company claims that it's process has an annual capacity of up to 15,000 gallons of diesel fuel per acre, per year. Joule also claims that the cost of production amounts to $20 per barrel, once government subsidies are factored in. At the time of this post, light sweet crude oil was being traded at a price of $89 per barrel.

TCC ENE-110 Students Build Solar Array

Tidewater Community College's Alternative Energy Program doesn't just teach theoretical concepts about solar energy. There's plenty of classroom learning, reading from text books and traditional testing, of course. Students also gain practical work experience in building solar arrays.

Some students plan on starting their own businesses in the future. Instructors also provided information about writing a business plans, incorporation basics, planning, estimating,and performing a SWOT analysis.

Wind-power Win Fall For the Shoshone-Paiute Tribes

Our nation’s history with the Indian tribes who were here before most of our ancestors has left much to be desired. Manifest Destiny had many manifestations of evil: callous indifference, intolerance, and bureaucratic incompetence have been the norm. Prime real estate was taken from tribes such as the Lakota, Pawnee, Shoshone, and Paiute and their people were driven to desolate areas that the government considered unfit for cultivation or hunting. However, the same wind that bears down on the inhabitants of the reservation system can now provide a new kind of currency… energy.

The Shoshone-Paiute tribes of the Duck Valley Indian Reservation have lent their support to the new China Mountain wind project that will provide renewable energy (400MW), new jobs, and economic development to the area. Perhaps other tribes of the wind-swept plains can soon benefit from the same thing.

2.4 MW solar installation at Pearl Harbor Naval Base

Of my 21 years in the U.S. Navy, I had the good fortune to spend 11 of them home ported in Pearl Harbor. There are many things that I remember about the islands... the beauty, the surf, scuba diving off Electric Beach, rainbows, and lots of sunshine.

Sunshine feels different in Hawaii. It's almost as if it either has a weight of its own or a downward, vertical breeze. Since Pearl Harbor is in a much lower latitude (21 degrees, 20 minutes North), sunlight is much more direct. Because of this high angle of the sun, there is less atmosphere to diffuse its energy. All of these factors combine to enhance the effectiveness of photo-voltaic (PV) arrays.

The following article from PV Magazine reports on a very large PV installation recently completed at Joint Base Hickam - Pearl Harbor:

2.4 MW solar installation at Pearl Harbor Naval Base
03. June 2011, By: Jonathan Gif

DRI Energy and Niking Corp. install SolarWorld photovoltaic panels on five key buildings at the historic US Naval Base.

Five rooftop solar energy systems worth 2.4 megawatts have been installed by the US military, as part of base improvements at the US Navy base at Pearl Harbor now know as Joint Base Pearl Harbor-Hickham. The project cost $15 million and was funded under the American Recovery and Reinvestment Act.

The solar systems where engineered, procured and installed by California-based DRI Energy working with Hawaii-based Niking Corp. The installation uses solar panels from SolarWorld, produced in their Californian and Oregon facilities. The solar panels have been installed but final configuration will be completed in the coming months.

The solar systems were installed over five buildings including a historic quarters, built in 1927; a headquarters building from the 1940s; and an on-site shopping and supplies center. The power produced will be enough to supply 440 homes.

The installation was part of the US military’s project to increase its energy independence using renewable energy technology that requires no fuel, parts, maintenance and produces no emissions or noise. SolarWorld’s Kevin Kilkelly said that it was gratifying to see the installation help power one of the world’s best know and historic military sites. “In that light, these projects may be the best signs yet of the nation’s embrace of domestic solar technology.”
