Energiewende - The Energy Transition

Sun and Wind Alter Global Landscape, Leaving Utilities Behind

"Electric utility executives all over the world are watching nervously as technologies they once dismissed as irrelevant begin to threaten their long-established business plans. Fights are erupting across the United States over the future rules for renewable power. Many poor countries, once intent on building coal-fired power plants to bring electricity to their people, are discussing whether they might leapfrog the fossil age and build clean grids from the outset."

My parents sent me this article.  It is very good.  If you are interested in reading the whole piece you can click here.

Triple Tracker Turns in 70K

Richard wrote on Halloween to note the 5-year anniversary of his solar PV power plant.  This was a fun project, and worth revisiting here on the blog.  The system is connected to Dominion Power's transmission system in Goochland Co. VA and has now generated more than 70,000 kWh.

The full post on the project which uses three dual-axis trackers from Array Technologies, SolarWorld PV modules, and SMA SunnyBoy inverter equipment was posted in September of 2011.  You can check it out by clicking here.

Bergey 1-kW Wind Turbine: Off-the-Grid in Garrett County, MD

LED Lighting Retrofit with D&E College GreenWorks!

I was asked to help the GreenWorks! club at D&E College replace a metal halide lamp at the entrance to the Eshleman Science Center.  GreenWorks! wanted to use an LED fixture that would consume less energy and they also wanted to add a light under the causeway to make it easier for pedestrians to see the stairs that wrap down and around the corner of the building.

Members from D&E's GreenWorks! club are shown here installing the two new LED fixtures and the conduit that connects them.  The club members installed a photo sensor on the light above the door to control the operation of both lights.

Here is the final product.  The replacement LED fixture is low-profile and blends in with the exterior of the building.  The club members did a really nice job of running conduit along the exterior to the second  light under the causeway.

Rob Orr, who is a club member, took these photos at night to illustrate the quantity and quality of the light produced by the new LED fixtures.  This light color is more white than the original metal halide fixture.  The metal halide fixture only illuminated the area in front of the entrance doors.  It was rated as a 130-watt bulb.  The LED that took its place consumes 10 watts and the new LED fixture under the causeway uses 30 watts.

Pretty cool!  Something else that is cool is that the Eshleman Science Center has grade-level entrances for each of its four floors.  That's impressive!!

Vacation Off-the-grid in Pendleton Co., West Virginia

Cowger Guest House 

& Rustic Camping Area

The Cowger Guesthouse (near Ft. Seybert, WV) is a beautiful log cabin dating from the early 1800's.  It sits amongst 1,000 acres of woods and is just a stones throw from the South Fork of the South Branch of the Potomac.  For whitewater enthusiasts, this is the last dwelling before you enter the Milam gorge (see whitewater boating pics here).

The owners, Larry and Sandra, remodeled the cabin in 2007.  It is comfortable and remote - almost a mile from a paved road with no cell phone reception or internet.  Electricity is supplied by a solar PV system installed by PIMBY.  The solar powers lights, the refrigerator, well pump, and other small appliances.  You can read more about the cabin and its rental terms at VacationHomeRentals.com or by clicking the link here.

Welcoming Spring with a Bergey XL.1 Install in Highland County, VA

Really this project should have wrapped up in late October of 2013, but delays on the part of the tower manufacturer had us wearing neoprene boots and brrrrr suits as we finished the install just in time for the 2014 Highland Maple Festival. 

This Bergey wind turbine replaces an ARE110 that was damaged several summers ago in the Derecho wind and rain events that moved through the mountains of Virginia and West Virginia.  Keith (who took this photo) and his wife Polly live off the grid in Highland County, VA.  The Bergey XL.1 is smaller than the ARE110, but it seems to be doing a good job of maintaining battery voltage through the night time when the solar sleeps and the radiant heat runs.
