A passive solar home utilizes home design to provide heating, cooling and natural light without the use of any special equipment.  A passive solar home basically uses the environment to accomplish great reductions in energy use.  A passive solar home uses construction materials and design to utilize the sun’s heat during winter months and block the sun’s heat during summer months.  There are several passive solar techniques you can use in a solar home, direct gain, radiant heat from sunlight passing directly into a living space and being absorbed by furniture, flooring etc and usually achieved with south facing window installations, indirect gain, involving an attached Trombe wall that collects heat and distributes it throughout the home by the use of fans, thermal mass, which are materials that naturally collect and store heat such as brick or stone, and passive cooling, which generally includes overhangs for south-facing windows to block the sun during summer months for cooling the solar home.

Another feature often found in a solar home is the use of solar electricity.  Solar electricity is generated when photovoltaic cells are used to absorb sunlight and convert it into usable electricity.  The energy produced by solar panels must be converted to DC (household power) through the use of an inverter.  Solar electricity can be used to supplement metered electric already being received by a solar home or with the use of a battery storage bank, can be used as the only electric source for the home.  If the later is going to be used, it is suggested that owners of the solar home have a generator available for backup power.

Solar water heating is one of the most common uses of solar energy in a solar home.  There are two kinds of solar water heating available for solar home use.  The first is a closed loop system, which can be used in areas that are not prone to freezing.  These systems use water filled tubes that are heated directly by the sun.  A closed loop system uses an anti-freeze type liquid to collect heat from the sun and then the heated liquid is used to heat household water via a heat exchanger.

Regardless of which steps you take toward converting to a solar home, energy efficiency is the most important attribute to a successful solar home operation.  Energy efficiency minimizes the need for heating, cooling and electricity.  Using higher insulation levels, more energy efficient windows, appliance and lighting than used in traditional construction, you will already be saving yourself a lot of money and energy.  However these changes may not be an option when converting an existing home into a solar home, so make any changes possible to your home energy efficiency and adapt other solar practices to convert your existing home into a solar home.

Any motivated do-it-yourselfer can learn how to make solar panels for their home, workshop or business.  When compared to the cost of purchasing and installing a pre-made solar energy system, learning how to make solar panels for your energy needs and the materials you need to execute the project are far less.  By learning how to make solar panels for yourself, you have greater control over the size and design of your system as well.

Once you have a quality manual and you have learned how to make solar panels, the supplies are fairly simple to find.  Most can be found at your local hardware store like, plywood, sheets of glass, and a roll of copper wire.  It is also easy to locate inexpensive solar or photovoltaic cells to use in your project.  Many are available over the Internet or you may have a retailer available locally.  One you’ve learned how to make solar panels and you have your supplies, it usually takes about a day to assemble a 100-watt panel.  This is the perfect amount of electricity to operate small appliances or a small workshop.

The most important step is finding a quality manual with detailed instructions for learning how to make solar panels.  In many cases you get what you pay for, so don’t be afraid to spend a few extra dollars on a well-reviewed instruction manual.  Overall, the cost of the making your own panels is so low, the price of the how to guide is minimal-you will still be paying way less learning how to make solar panels on your own than purchasing a professionally installed system.

With a little bit effort, you can be on your way to learning how to make solar panels to meet your energy needs.  Then sit back and bask in the pride the next time the power goes out on your block.  Your lights will still be on because you learned how to make solar panels and your energy supply is still in your battery bank.

Oil and gas have already become too expensive, and with each passing day, they are moving towards being extinct. Some ignorant people think that energy crisis is a myth. They fail to see the big picture. There have been three major energy crises so far – the 1973 oil crisis, the 1979 energy crisis, and the 1990 oil-price hike, apart from several regional crisis.

Prices have been rapidly increasing for the last five years, thanks to the ever-increasing demand and the increasing shortage of energy resources.

How soon will it be all gone?
Are the cynics right in saying that we are making a mountain of a molehill, or is the energy crisis for real? Picture this: We have already exhausted 50 percent of the available oil. At the current rate of consumption, the rest of the oil will finish in 32 years! Imagine if the rate of consumption increases! We all know it is bound to increase. So, even the present generation will face an acute energy crisis in the later years, let alone future generations.

What are we doing about it?
Are we equipped to face the impending energy crisis? What can you and I do to tackle it? For starters, we need to understand the importance of energy in our lives and stop taking it for granted. We have to minimize the use of oil, gas, electricity, or any other fuel. We cannot afford to waste any available energy. It is also important to spread awareness about limited availability of energy resources. Simple things like joining a car pool, switching off car engines at traffic lights, and minimizing the use of gas and oil in everyday activities will help a long way in crisis-readiness.

What are the alternate energy options?
As a responsible world citizen, start looking for alternate energy solutions like solar energy and wind energy. Employing these alternate power solutions is extremely feasible and cost-effective. You will not only cut down your power bills but also contribute to a better future of the world.

With that clear, are there truly benefits on a home or small business level to renewable solar technology? Absolutely.  Truthfully, by utilizing renewable energy technology on a home level you can save yourself thousands of dollars each year.  Renewable energy technology has gained popularity in recent years and it has become increasingly easy to meet your home’s energy needs with just a little handyman work.  With the information available about renewable energy technology, it is possible to build renewable energy products, such as a windmill or solar panel, on your own.  Do-it-yourselfers are saving huge amounts of pocket change by building and installing these systems themselves.  If you have the money to invest in a commercial professionally installed system, in general these are more efficient, however, savings can still be realized, and at a much faster rate, by researching and building your own renewable energy systems.

Renewable energy technology is advancing with each day.  Solar electrical systems have advanced from giant roof panels to thin layers of film that are twice as conductive and work with less sunlight.  There are now solar powered charges for cell phones, batteries and other small household items.  Windmills have been made more aerodynamic for greater action and electricity generation.  Renewable energy technology can even be seen along today’s highways as small solar/wind operation stations powering signs and lights.

The truth is renewable energy technology is working and you can put it to work for you in your home or business.  With growing popularity and more consumer use, renewable energy technology could minimize our effects of global warming, help alleviate financial stress and create a world less depend on fossil fuels.

Let us look at how you can save power at home.

Computer: More often than not, we do not switch off our monitors even after we have shut down our computers. Keep the monitor and the computer switched off when you are not using them. Start practicing this even when at work. You will help save some more power for the world.

Light bulbs: You must have seen compact fluorescent light (CFL) bulbs being advertised all the time. You must have even used them at times. As a power-saving measure, start using the CFL light bulbs as much as you can. If you are thinking they are more expensive than the regular bulbs, the benefits of the CFL bulbs will prove much more cost-effective in the long turn by the amount of power they will save.

Air Conditioner: Set the temperature at the minimum or maximum best you are comfortable with, depending on the season. Try not to set it at too high or too low temperatures. Setting the air conditioner at reasonable temperatures helps save a lot of energy.

Washing Machines: Do you use your washing machine as often as you want? Do you use your washing machine even when there are not enough clothes to wash? Minimize the number of washes by washing full load of clothes every time.

Television: Take off the power plug of your television set when not using it. This may not sound a big deal but this tiny step will help save power.

Geysers: Keep the geyser thermostat at the minimum heat. You do not need to heat the water at a very high temperature or for too long.

Refrigerator: Bring hot food to room temperatures before putting it into the refrigerator. You can also save power by taking cold or frozen food out of the refrigerator much before the mealtime, thereby saving power in heating it.

Car: For an air-conditioner equipped car, pull up the windows of your car before switching on the air-conditioner.

This article will list some simple, easy-to-do things to reduce your electricity bill.

Limited use: Start with the room you are sitting in. If you were to take a call in another room or join your family at the dining table, would you just step out of your room without any concern for the electrical appliances in the room? If you would, stop right there, and look around. Switch off all the appliances even if you would be back in five minutes. Yes, even that will help. Every drop of water constitutes to the ocean.

Another thing to take care of here is what you perceive as an electronic appliance. Would you switch off the television set, turn off the fan, but not the light bulb? Yes, you need light, but not now when you are leaving the room. Taking care of these small things will go a long way in reducing the dreaded huge electricity bills.

Smart investments: Make some smart power investments by replacing your incandescent bulbs with compact fluorescent light (CFL) bulbs. These bulbs are a great power-saving investment.

Buy the Power Save gadget. The gadget helps monitor the power supply to your house and uses the minimum that is needed.

Home appliance usage: Most of us complain that the electricity bill touches the sky because of the number of electrical appliances they have at home. However, the electricity bill is not directly proportional to the number of gadgets you use but the way you use them. Let’s see how you can avoid the typical power-wasters.

• Use the washing machine only when there is a full load of clothes.
• Keep the geyser on for the minimal amount of time.
• Keep the air-conditioner at the minimum low or high temperature, just enough to keep you off the heat or the cold outside.
• Switch off the computer monitor even when you take a one-minute break. It takes just a second to switch on the monitor again!

Yeah, you have to stick to this way of life for saving power at home and for the world.

Remember, reducing your electricity bill is equivalent to saving power, thus helping the world save power for its future generations.
