SERC Display Illuminates Efficient Solar Home Power Systems

SERC’s Lighting Lab recently finished testing efficient DC lighting products for use with off-grid solar home systems, as part of a competition administered by the Global Lighting and Energy Access Partnership (Global LEAP) Awards program. To highlight the awards program, SERC incorporated some of the winning products into a tabletop display illustrating the difference between a solar-powered system with inefficient lighting and one that uses state-of the-art LED lighting and super-efficient appliances. The display was then presented at the Fifth Clean Energy Ministerial (CEM5) conference in Seoul, South Korea, on May 12 and 13, where ministers, energy officials, and observers from more than 21 countries and the European Union were in attendance. This year’s slogan was “Act Together, Think Creative.”

Each system includes a 40 watt (W) solar panel, a charge controller, and a 70Ahr battery. In the “inefficient” system, these power a single 25 W incandescent bulb for five hours a day. In the “super-efficient” system, the same solar panel and battery can power two LED lights, each brighter than the 25 W incandescent, for five hours a day; one radio for five hours a day; one 13 W super-efficient flat panel television for over three hours a day; one 6 W super-efficient fan for four hours a day; and one cell phone charger.

Clearly, the use of high efficiency appliances can greatly enrich people’s lives.

This project was a collaboration between the US Department of Energy (US DOE), the Collaborative Labeling and Appliance Standard Program (CLASP), Lawrence Berkeley National Laboratory (LBNL) and SERC. Our team at SERC designed and built the portable display, while Carolyn McGregor of the US DOE, Matt Jordan of CLASP and Won Young Park of LBNL attended the CEM5 conference and manned the booth.

Yurok Energy Upgrade Complete

The Yurok Tribe recently completed energy upgrades at their Klamath and Weitchpec Tribal offices. This included the installation of a 15.7 kW AC solar electric array in Weitchpec and energy efficiency upgrades at both locations. As reported in our Fall 2011 newsletter, SERC provided the Tribe with technical support for the project. This included services from start to finish.

Initially, SERC helped the Tribe secure American Recovery and Reinvestment Act (ARRA) funding for the project and worked with the Tribe to define the scope of project activities. In addition to ARRA funding, SERC helped the Tribe secure a rebate from the California Solar Initiative program. This offset part of the cost of the solar electric system.

Humboldt County Clean Energy Futures

Humboldt Bay Power Plant

The generators will be a good match to intermittent renewable energy like wind and wave power. (Photo credit Jim Zoellick)

The Humboldt County Renewable Energy Secure Community (RESCO) project gives all of us at SERC a welcome opportunity to focus our effort on the community where we live, work, and play. The goal of the RESCO project is to forge a strategic plan for Humboldt County to develop clean and renewable energy resources that meet at least 75% of our electricity needs and a significant fraction of our heating and transportation needs. Our main project partner is the Redwood Coast Energy Authority (RCEA). RCEA is focused on political and strategic issues; SERC is doing the technical and economic work.

Working with the Yurok Tribe on Energy Efficiency and Renewable Energy

Evaluating Yurok PV Installation

The Schatz Lab has a long-standing relationship working with the Yurok Tribe on energy projects. Starting in 1999, we installed a fuel cell power system at School House Peak that powered their cell phone repeater station. Since then we have installed a residential off-grid solar electric system and conducted energy planning and needs assessment work.

Currently we are conducting a feasibility study to examine the potential for wind- and hydro-electric energy generation on the Reservation. We have been collecting stream flow data on Pecwan and Ke’Pel Creeks for about two years, as well as wind speed data on McKinnon Hill for the past year. We are now analyzing the data, determining the energy generation potential, estimating project costs and potential revenues, and conducting life-cycle economic assessments. The final results of this study are due early next year.

Promoting Nationwide Energy Efficiency Through Measurement and Performance-Based Rewards

2008 Performance Based State Efficiency Results

Over the last two years, SERC has been engaged in energy efficiency policy analysis at the national scale. The National Resources Defense Council’s Center for Market Innovation contracted SERC to answer the question: Can progress in energy efficiency and energy conservation be tracked at the state level? If so, can a metric be developed to rank states and reward high performers? In short the answer is yes, but better data are needed before the government should begin to implement a program to reward states for energy performance.

SERC Returns to Redwood National Park

UNPEPP Interns with Ray Cozby

Three HSU students spent their summer as SERC interns helping to reduce environmental impacts at Redwood National and State Parks. Funding for the collaboration was provided by the nationwide University-National Park Energy Partnership Program (UNPEPP). UNPEPP links national parks with university students to provide energy services to the parks and real-world problem solving opportunities for the students. This was SERC’s sixth UNPEPP-supported project at the Redwood parks since 2000.
