HVAC Zoning Controls

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).

Make Your Next Science Fair Project Green

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.

Making Solar Electric Systems Pay Back Fast

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.

Product Review of Online Energy Analysis Software - The Home Energy Saver

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.

Safer Cooking With Solar - Using The Sun For Emergency Preparedness

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).

Tracking Energy Waste

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.

Using Solar Energy In California

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).

Wind-Diesel 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.

Beginner's Guide To Solar And Wind Energy

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?

Cost Effectiveness Of Photovoltaics - Solar Electric Power Panels

News articles indicate that photovoltaics are already cost effective in Hawaii and some parts of California. Photovoltaics are also cheaper than electric grid power if you wish to power a remote home that is more than 2 miles from the nearest power line.

EarthToys Introduction - Who Are We And What Are We Trying To Accomplish?

My view is that while we would all like to believe that the decision to use alternative energy sources by individuals will be justified economically ... or politically ... or culturally ... in fact the primary market growth for the products and services in this industry will be driven by responsible people who just want to feel good about the way they conserve or create energy.

Energy Conservation - Tips For Your Home

Solar electric systems have high up front costs. Before going solar electric, you should conserve as much energy as possible so that your solar system can be smaller. Here are some tips on conserving electrical energy.

Good Advice About Steam

Steam, as with other forms of alternate energy has it's realm. Where steam excels above the other common systems, is in an application that requires large quantities of controllable, useable heat.

Maximum Power Point Tracking

Maximum Power Point Tracking, frequently referred to as MPPT, is an electronic system that operates the Photovoltaic (PV) modules in a manner that allows the modules to produce all the power they are capable of.

PV Innovation - Here Comes The SolarQuilt

The design is simple yet truly effective in offering to the building owner an aesthetically pleasing, lightweight photovoltaic roofing system that rests on flat or low slope roofs, requires no roof penetrations, protects roofs from weather and UV radiation and produces cost effective solar electric energy.
