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.
The automobile manufacturers claim that very few people (apparently less than 1000 people in the USA) are willing to buy electric automobiles. However, I know many of us would like to "refuel" our cars by plugging them into an electric outlet at home. If we work together by educating the public, the news media, and the automobile manufacturers, we can make production volume electric automobiles and Grid Rechargeable (plug-in) electric-biodiesel hybrid automobiles a reality.
Remember to keep your batteries full and happy to improve the performance of your alternative energy system. Since alternative energy is the wave of the future let us pioneers learn how to operate them properly today!
Electricity savings for a household of four occupants varied from about 200 kW-h/year to 400 kW-h/year for a single point of use. Extrapolation to a home with at least four points of use would imply electricity savings from 800 kW-h/year to 1600 kW-h/year.
Homeowners would like to increase their comfort level while conserving energy. An excellent method to do this is through zoning. Most two-story homes have an 8 to 10 degree temperature difference between upstairs and downstairs (because heat rises). Additionally, larger ranch homes generally have a big temperature difference between one end of the house and the other (due to the distance of the duct runs).
One excellent idea is to create a miniature "hybrid" renewable energy power plant. This could be accomplished by combining solar cells and a small windmill kit. Such an idea could graphically demonstrate the complementary nature of these two free power sources.
You are an excellent candidate for a solar electric system if your electric bill is over $75 per month, you pay more than $0.12 per kwh for electricity, your state offers substantial rebates for solar electric systems, and you have good solar exposure.
Spending a few minutes with this software can provide as much education as reading several books on energy saving construction ... in real terms ... with your own house as an example. The tips provided along the way are very helpful and having the "Energy Efficient House" costs listed gives you a great target to shoot for.
I use my Global Sun Oven to cook anything that I would normally cook in my regular oven. My family loves fresh-ground wheat bread and we regularly cook roasts, cookies, rice, casseroles, baked potatoes, cakes and more. I can't tell you how many times I've been told that sun cooked chicken tastes better than Kenny Rogers' rotisserie chicken (and I love K.R. chicken).
The Submeter shows you where electrical power goes in your apartment building, office, marina, or RV park! Do you have a "smart house"? A submeter can track all of your branch circuits and report power anomalies. Read and control from any internet connection.
The main impetus for the accelerated interest in solar electricity has been the California Energy Commission's rebate program. They offer rebates of $4.00 per watt for homes and $4.50 per watt for businesses (approximately 50% of the total installed cost of solar electric systems).
Making a hybrid power system work in the long run is not just about buying and installing the equipment. Like with any other technical system, there must be adequate documentation of the installation. Operators and maintenance personnel must have proper training. Funds must be allocated for maintenance and repair, e.g. to replace a worn-out battery bank or hire a specialist for troubleshooting.
The question is why are you interested in using solar or wind energy? Is it because you need some back-up electricity for when the utility grid is unavailable? Or is it because you want to spend less money per month on electricity?
