How to save power at home
We all learned about the renewable and non-renewable sources of energy in school. However, we never paid much attention to the rapid consumption of the non-renewable sources of energy until recently. The world is faced with severe energy crisis now and none of us remain unaffected anymore. Should we leave everything to the governments, or can we do something to save power? The answer is simple: we can.
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.For More Energy Saving Ideas!<

How Much Electricity Does a Wind Generator Produce
How Much Electricity Does a Wind Generator Produce?
By Gary Ashby
If you are interested to build a renewable wind generator system to run your home with wind power, you need to first understand how electricity is produced with wind energy and how much electricity can be produced by the wind turbines.
Wind is a result of different temperatures on different surfaces of the ground at various times of the day. When a part of the ground is heated up first, the air above it becomes warm and rises. The cooler air takes over the space left by the warm air and the result is wind.
1. How Does A Wind Generator Turbine Work?
As long as there is wind, the wind generator will be able to capture the kinetic energy and convert it to electrical power inside the system for your home use. It is usually installed on the roof of your house for maximum efficiency.
If insufficient energy is produced from the wind generator system, you can still draw electricity from the utility company, especially at times when the air is almost not moving. However, when a lot of electricity is produced, especially when the wind speed exceed 7 mph, there is a chance that you can produce excess electricity which you can then use to sell back to the utility company.
2. How Much Electricity Can One Wind Turbine Generate?
The electricity that a wind generator can generate will depend on turning speed of the rotor and the turbine's size. A 10-kW wind turbine can generate about 10,000 kWh a year at a location with wind speeds averaging 12 miles per hour, or about enough to power a typical household. A 5-MW turbine can produce more than 15 million kWh in a year, which can be used to power more than 1, 400 households.
Thousands of people have already eliminated their own home electricity bills with this free energy system. They learned how to build it by downloading a step-by-step guide online. You can find out more about how to build this homemade power system at the website link below.
