Evergreen Solar, Inc. (Nasdaq: ESLR), a developer, marketer, and manufacturer of photovoltaic (solar power) products for the worldwide market, announced today that it is the recipient of the Worcester Business Journal's 2003 Environmental Award for making advancements in solar energy.
Sacred Power Corporation Nears End of Renewable Energy Project with Completion of New Solar Carport at SIPI
The 10 kilowatt photovoltaic, single-axis tracking, grid-tied solar carport will provide learning example technology for the myriad of Southwest Indian Polytechnic Institute (SIPI) students who are enrolled in the newly created Renewable Energy curriculum.
One thing is perfectly clear: you would be foolish not to use at least a conventional energy-star refrigerator, and even with those, you need to be aware that there is a wide variation, mostly dependent on style and features of the unit.
Eskom has gone to lengths to make this installation blend with the environment. Virtually no real estate is taken up (farming can be done right underneath the units) and standing under windmills of this size not unpleasant at all ... even the cows seem to like the gentle swishing sound they make ... as witnessed by the locations of their deposits :-)
It's not often we associate something that consumes power-such as lighting-as a means to saving or conserving, but by their inherent design and very purpose, lighting controls are a way to not only save electricity and related costs, they're a fun, convenient and futuristic way to go about it.
Take a moment to program in your electric utility rate ($ per kwh) and the unit will tell you the total cost of running the appliance during the time of monitoring. Push the "Cost" button again and it will calculate the cost per day ... another button push = cost per month and one more push forecasts the cost per year.

This huge residential system was a great success for the Laursens, and for Sierra Solar Systems who provided the equipment. The family has now completely eliminated their high utility bill and will be powering their home for generations to come with clean renewable energy. In addition, local wildlife will receive the benefit of a year-round drinking supply.
It is not fun being without air conditioning in the summer. Several years ago we had our house unit go out on the hottest day of the year. It was 126 degrees F in the shade and even hotter in the house. Fish were dying and we were miserable. After searching for two days I finally found a window swamp cooler that got us by until we could get the house air conditioner fixed.
We know that conservation is important, but exactly how many dollars should be invested to save a KWH? We answer this question by comparing the investment necessary to produce one KWH/day with the cost of conserving one KWH/day. Even though a KWH is relatively expensive, with effective investments in conservation you can substantially reduce the total cost of operating a home with a stand alone power system.
Expect cautious incursions into the world of deployed energy management solutions in the beginning. Eventually, however, we believe that commercial deployments in larger numbers will be the norm, at least in certain markets. After 30+ years of watching a market evolve at a painstakingly tortuous pace, the next few years should provide some interest and excitement.
