Welcome to the solar energy revolution! We are all going to be involved in the drive toward energy independence, that is, becoming independent from foreign oil. Gasoline is selling for more than six dollars a gallon in both Germany and the U.K, and we know that, for all kinds of reasons, it’s bound to go up much more in the not-so-far future. Coal is plentiful here in the U. S, but the efforts to clean it up are going to be painful and slow in coming. The transition to solar power is also going to be painful and costly, but eventually it will begin to pay for itself. For homeowners especially, a move toward solar energy is really a wise investment, whether they are building new or doing remodeling.

Some banks are beginning to loan money for solar retrofits. The solar energy facts clearly show us that once the payoff is complete for such a loan, the homeowner is ahead a great deal-even as much as the whole of his total former energy costs. We have many suppliers in this country who can design systems for every environment and climate.

We’re going to look at four main systems for a homeowner to consider when going solar:

-Solar hot water
-Solar electric or photovoltaic
-Geothermal heat pump
-Wind turbine

Solar hot water is a terrific investment due to low cost and high efficiency. Space heating can be incorporated for a slightly higher expenditure. An outlay of three to ten thousand dollars could lower your energy demands from thirty to fifty per cent. Our solar energy facts show us that hot water represents the second highest energy demand in U. S. households.

Solar electric or photovoltaic is another of my personal preferences because this is an arrangement usable by almost every household. A system consisting of photovoltaic panels with a grid-tie unit eliminates the need for storage batteries, and if supplied with enough solar panels, can even pay a homeowner for excess electricity generated. The costs for such a system are probably going to run from five to twenty thousand dollars. Photovoltaic coupled with solar hot water can be an ideal solution for many homeowners.

Geothermal heat pump- Although geothermal is not really solar energy, it is certainly renewable energy. Geothermal uses the constant temperature of the earth along with a sophisticated heat pump to either heat or cool the home. There are also designs which supply hot water as a part of the process. The installation of this scheme requires either a well be drilled or extensive trenching be done. The cost of this along with the heat pump may be somewhat costly. Photovoltaics or wind would also be an important part of any complete project.

Wind power is an extremely good source of power for anyone who lives in an area of plentiful wind and preferably doesn’t have neighbors too close. If a grid-tie is not possible, storage batteries can be installed. Costs for wind power machines can range anywhere from five hundred dollars for a small unit to as much as twenty thousand for a high end grid-tie unit with a sixty foot tower.

When we lok at headlines that say, “Pump prices rising despite glut of gasoline” (Chris Kahn-AP) or this: “Oil prices rise again” (APA), the solar energy facts assure us that by investing in solar power we can go a long way toward guarding our energy future. With the abundant sun’s energy in the southwest and the winds available in other parts of the country, our goal of energy independence is much brighter.

I recently did all this research right before we purchased our new refrigerator. Since the refrigerator is one of the larger appliance purchases for your kitchen and will probably last you 10-15 years you need to choose wisely. I was surprised to find that there is such a variety in refrigerators these days. There are many styles and sizes, different colors and finishes and many features to choose from. Then of course you must check out if it is Energy Star qualified. Here is a summary of what I found out. Hope it helps you out!

Styles

1. Small Basic Refrigerator – These are best for smaller families, apartments or small kitchens. Generally it is about three to six inches narrower than your regular size refrigerators.

2. Top-freezer Refrigerator – These are still the most popular refrigerators around and are less expensive than some of the other styles below. They are generally spacious and very good for everyday use.

3. Bottom-freezer Refrigerator – These are very similar to the top-freezer version except the refrigerator is on top and the freezer is usually a pull out drawer on the bottom. It is more convenient as most of your daily use items are at eye level. The bottom freezer though can be awkward as there are no shelves and making it difficult to find specific things.

4. Side-by-side Refrigerator – This has two separate areas for the refrigerator and freezer side by side. The freezer side a little smaller. This style will be good for smaller kitchens where a wide door clearance is a problem. Most of these come standard with an in-the-door ice and water dispensers. You do lose some space on the refrigerator side as a result of this configuration and you will not be able to fit things like wide platters, cakes boxes and pizza boxes.

5. French Door Refrigerator – This is a mix between bottom-freezer and side-by-side refrigerators. The top refrigerator portion has two French doors but the inside shelves are the full width. The freezer is a pull-out drawer. Again you have the benefit of not having to bend down to reach your everyday items.

6. Built-in Refrigerator – This is the custom refrigerator that lies flush with your kitchen cabinets and can be made to look just like them. These of course are expensive. These days you can also find refrigerators made the depth of standard cabinets so it looks like a built in. This route is significantly cheaper than custom built-ins.

Features

* Automatic defrosting – Most new refrigerators have this as a standard feature and I think it is a must. Gone are the days of having to unplug and defrost yourself.

* Power Failure Warning System – This alerts you if there was a power outage while you were not around. It usually also displays the highest temperature reached so you can make a decision on discarding spoiled food.

* Ice Maker – These are pretty standard these days

* Filtered Water – Whether you have an in-door or in-refrigerator water dispenser or just an ice maker, having your water filtered is a good idea.

* Water Filter Indicator – This will notify you when it is time to change the water filter.

* In-Door Water and Ice Dispenser – This is usually standard on the side-by-side refrigerators but is harder to get on the others. Recently the French Door models are starting to give this option. This is a great feature to have specially if you have children. Less wasted energy by fewer occasions to open the refrigerator.

* Rollers – You can lock and unlock wheels as needed making it a lot easier to move the refrigerator. I find this great for cleaning.

* Adjustable shelves and trays – This is something that to me is essential. Almost makes you refrigerator custom for you. I tend to readjust shelves fairly often so to me ones that are easier do do will be important.

* Larger shelves in the door – These can accommodate gallon jugs of milk or large soda bottles.

* Cooling Zone – Cold air from the freezer section is diverted to the refrigerator door helping milk and juice, usually stored here, to remain fresher longer.

* Electronic Temperature Controls – This ensures precise temperature control in the refrigerator and freezer sections.

* Express Chill and Express Freeze Settings – This is great for when you just can not wait.

* These days some refrigerators even come with things like a television, radio, or DVD player built into a door.

Colors and Finishes

Most refrigerators come in various color choices along with your basic white and black. Stainless steel finish is very popular these days and will cost you approximately $250-$300 more. Some manufacturers are now offering fingerprint-resistant stainless steel. This is just a clear acrylic coat on the finish that resists marks. You can also opt for faux stainless that also resists finger prints.

Energy Efficiency

When shopping be sure to look for the ENERGY STAR yellow label which is required to be on display. This label provides an estimate of how much energy the appliance uses, compares energy use of similar products, and lists approximate annual operating costs. Manufacturers have to meet strict energy efficiency guidelines set by the EPA and US Department of Energy so this a good representation of efficiency. Although you may notice that higher efficiency costs more, remember you will save a significant amount on utility bills every month and help the planet.

Energy efficiency is very important but so is getting all the features you really want for the long run. So choose wisely! Good Luck!!
