One of the small things we could do to conserve energy is by using energy saving light bulbs. As the names suggest it, energy saving lights saves energy. It can save money too, for their will be less electric bill. So many folks …

Honestly, I have only used those curly spiral incondescant light bulbs for about 6 years now. My electric bills without electric heat and without sdummer tempertature air conditioning have saved me easily $350 to over $1200 …

Wind has been considered as a downside of regions, a factor that conspired against urbanization, highlighting destructive power of the wind. But more recently, technology has provided a whole new outlook on the wind. Regions with steady regular wind have proven to be the most suitable ones to produce a new way of cheap and clean energy: wind energy. You can read more information about it by reading the article below.
Wind energy can be “harvested” with the use of wind turbines. Wind turbines are roughly structures with big propellers that take advantage of the constant movement of the propeller, generating energy. In the same way mills took advantage of wind, typically to extract water from the soil, these new wind turbines generate electricity in an efficient way. Technically, it can be said that they convert the free everlasting kinetic energy of the wind into electricity. No chemistry is involved, because it is simply an ingenious device that transforms energy into usable ways.
A Wind Turbine Energy consists mostly of three main components: the rotor blades, the shaft and the generator. A lot can be said about the design of the blades. They need to be aerodynamically shaped, so as to make the most of the wind, with the least loss of energy. This includes careful consideration of the materials blades are made of. At first, wood was the preferred material. Later on light metals were used, like aluminum. The most suitable is carbon fiber, an extremely light material, amazingly resistant. The shaft is connected to the rotor. It transfers the movement to the rotor, which has one end attached to a regular electric generator. Here is where the electric energy is produced. This is a very simple, yet very effective mechanism. Electricity will be produced as long as the blades spin.
The generator works using the properties of electromagnetic induction. The core of the generator is made of magnets, that when moved constantly close to a conducting material –copper wires, most typically-, produce a difference of electric tension –voltage. Magnets have this amazing property: to release electrons: energy.
Windmills are used in areas where traditional wiring is not present, for instance in rural areas. In 1930, 600.000 windmills provided water and electricity to many rural areas in the United States. By 2006, new windmills were developed that could produce up to 4 mega Watts of electric power, enough to supply energy to a small neighborhood with one single mill. The new wind turbines have a completely different design from traditional mills, the axis being placed vertically, instead of horizontally. This new layout helps maximize the power of rotation of the wind. This design is called VAWT.
The size of the Wind Turbine Energy mills is highly relevant. The bigger the mill is, the most energy it can produce. The drawback is that bigger structures require bigger parts that will necessary gain in weight. That is why new materials such as carbon nanotubes and glass fibers are so effective when designing mills.

It is continually stated that incandescent light bulbs use excessive quantities of energy and cause harm to the environment. In addition the environmental supporters have now lobbied government to legislate for the light bulb ban. This is a phased activity to constrict the use of incandescent light bulbs and move to energy saving light bulbs . I will now supply information on precisely what is the impact on your carbon footprint by changing to energy saving light bulbs and compare this to carbon footprint amount for vehicle use and other electrical appliances.
What amount of C02 can you save by changing to energy saving light bulbs .
Electric light bulbs intrinsically do not create C02 , however, it is the carbon dioxide that is made during the electricity generation that is the concern. Now decisively if you are using windmills or hydro-electric power to make your electricity then C02 emissions will be very little. However, most electricity is generated from oil or gas powered generators which do create a considerable amount of C02. Lets look at the carbon footprint numbers. If a single conventional incandescent light bulb is used for 4 hours a day and this is swapped for an energy saving light bulb then this will save a breath taking 100kg in C02 emissions every single year.
Checking out the comparison with transportation and other ways to save C02.
This is all very factual but does 100kg of C02 released into the atmosphere really matter and are there not alternate actions, other than using energy saving light bulbs, that can be taken to achieve the same goal? I think the best way to look at answering these questions is to examine some comparative examples.
1. Consider that you take a sample family car the Ford Focus C-Max 1.8 (125PS). If you drive this for 330 mile less every year then this will make an equivalent saving to swapping one of your light bulbs for one or your energy saving light bulbs.
2. If you can amend your travel patterns to avoid 1000 miles of train travel, then this will save 100kg in C02 emissions. Energy Saving Light Bulbs can make a similar reduction simply through swapping just one.
3. If you fly from London to Glasgow on a full plane then this will create of 100kg in C02.
Checking out these comparisons then migrating to energy saving light bulbs does look like a no brainer.
So what does that all mean?
It is clear to see that swapping to energy saving light bulbs will make a big improvement to your carbon footprint but there are other aspects worth analyzing.
Dishwashers and washing machines do use around 3 kWhours of electricity each time they are used. As a comparator to a light bulb, if they were used twice weekly, this is largely similar to having 2 100 watt light bulbs switched on for 4 hours a day. As I am sure you can see that whilst these amounts are fairly high they are not excessive so simply make sure the appliances are full and do not use your tumbler dryer if the weather is good.
