Our daily life revolves around pollutants so you can imagine the importance of cleaner and green environments in our lives.

Reasons Of Environmental Pollution

There could be multifarious reasons behind air pollution, but most common reasons of air pollution is due to the smoke of diesel and petrol found commonly among roads and industrial areas. The factories consume power energy source, which results in producing environment pollutants and becomes the cause of air pollution. More reasons include increasing number of smokers globally which are also one of the reason of increased environmental pollution

The Cause Of Diseases

However even if there is no direct controlling technique for environmental pollutants, they can directly attack individual’s sensitive body parts that include lungs, brain and exposed body parts. Air pollutants have been found as one of the major reason in cause of harmful diseases such as asthma, chest problems, breathing unevenness, travel symptoms, fever and many normal health problems that requires immediate care and doctor’s advice

If you are exposed to extended air pollutants while at work, you must take measures to secure yourself from such dangerous activities. Your life could become better only with the help of safety control procedures, which you need to incorporate in your life to improve the chances of better work performance. The impact of environmental pollution is dangerous and the rightful control at all points could contribute better health and future

Reducing Electricity Bills By Solar Powered Systems

Tags: , , , , , , , , , , , , , , , , , , , , , , , , , ,


There is a financial incentive for businessmen in installation of solar powered systems in their businesses and work places to generate electricity. The monetary benefits come in the form of rebates and tax relaxation. Also, with advanced technology, solar energy is not used just to heat up water, but is actually converted to electricity. Thus, lights, computers and other appliances could be run from energy derived directly from the Sun.

One example of the financial incentive exists in the state of California, which estimates $4000 per kilowatt of rebate and 15% tax credit. Generally, people are encouraged to use solar powered systems because of numerous reasons, like less pollution from power plants, saving the reserves of fast depleting non renewable resources like coal and oil from earth etc. Also, the person will help lessen his ‘carbon footprint’ on the earth.

How Does A Solar Powered System Work:

How Does A Solar Powered System Work

There is a photovoltaic cell that collects sunlight, and is tilted and faced due south to enable it to collect the maximum amount of energy. It is installed on a rooftop, ground, pole, or any suitable place to avail maximum exposure to sunlight. The DC current thus produced is fed to an inverter which produces AC current, which is the form of electricity provided by the power stations to houses and workplaces. The inverter synchronizes the current with that produced by the grid, and supplies it via the utility meter to the grid.

Connection to The Power Company:

The electricity is supplied to the grid and so the utility meter may run slowly, indicating less energy used from the power station, or even backward, indicating energy being supplied to power station. In a “Net Metering State” like California, the power company is supposed to pay the full retail price for the power produced by individuals.

Benefits Of A Solar Powered System:

They are easy to install with no moving parts that are breakable, no rigorous monitoring required, and no noise. They have a warranty of as long as 25 years. This means that even after the payback period (the period required to cover investment cost) has passed, it keeps running and yielding profits.

Need Of Batteries For Solar Powered System:

If there is a power failure from the utility company, there is no electricity supplied to the grid by the inverter to save any person from an electric shock in the event the utility company sends a lineman for maintenance or repair. With a battery powered system, backup energy is supplied to the individual’s company or work place; otherwise there will be no electricity available for the person’s business. So depending on the type of battery, electricity could be supplied for hours, and even days, however, with the battery powered system there is a reduction in efficiency of electricity produced. So, there is less profit made by selling electricity to grid, as well as additional cost of replacing the battery pack every 5 to 6 years.

Determination Of Daily Electricity Usage:

Before installation, the business owner should know the power consumption of say, his workplace, by asking the utility company about the power consumption in kilowatt hours per day or per month. Read the full story

Tags: , , , , , , , , , , , , , , , , , , , , , , , , , , ,


Compact fluorescent light bulbs are fluorescent lamps which are replacing the incandescent lamps commonly used in houses. They have less power consumption. So they save money as well as conserve energy. This means that the higher purchasing price of a fluorescent lamp is easily recovered.

Advantages:

Fluorescent Light Bulbs

The power savings are upto 75%. They last about 6 to 10 times longer than the incandescent bulbs normally used at homes. This means that if an incandescent bulb used 5 hours a day lasts 6 months, a fluorescent bulb will last 3 years.

Impact on Environment:

Recently, there has been a global awareness regarding the need to conserve energy. This is because many non-renewable resources will be depleted if continued to be used without restraint. By using less energy, Compact Fluorescent Light Bulbs serve this purpose. They also reduce pollution caused by power plants in producing electricity.

Money Saving:

First of all, your electricity cost for lights is reduced by 75%, if you were using incandescent lamps before. Money is also saved as Compact Fluorescent Light Bulbs need not be replaced that frequently. So the initial extra cost of purchasing is accounted for.

Operating Life:

An incandescent bulb operating at 60 kilowatts is equivalent to a fluorescent bulb of 13 kilowatts. They are designed to last 6000 to 15000 hours. Incandescent bulbs will last only about 750 to 1000 hours in comparison.

Calculations:

Cost of fluorescent bulb: 3 dollars

Cost of an incandescent bulb: approximately less than a dollar. Read the full story

The solar power is increasingly becoming economically feasible as the new mode of power generation, the solar power is eco friendly and very economical as compared to the other methods of power generation. Investment has started making its way to the solar power generation projects and the technology is continuously evolving, becoming more and more efficient. It looks as if it shall become the major source of power generation in a short time.

Solar Power Generation Prices are getting Competitive

The factor that till a few years back kept solar power from overtaking the power generation as a major production source was it being expensive. When compared with the coal generated power, the coal generated power was a remarkable 90% cheaper than the solar power generation. Now the changed and recession hit economy of the world has played a major role in bringing down the prices of solar panel from 10%—30% in the last six months. Contributed to this lowered price is also the investment that is making its way in this power generation means, an example being the 3 times lowered prices since May, of the Sharp solar panel from a $5/watt last year to $4/watt. Many of the projects which previously could not be considered would now become feasible because of this price decrease. Read the full story

All the solar thermal plants in USA are not pollution-free. It is because they use different kinds of fuels as well. They are the result of several kinds of pollution and harmful effects to the environment and the atmosphere.

Solar thermal plants

They are so called the green-energy alternatives. They make use of the energy coming from the sun and are expected to be pollution-free. They are thought to be a great contribution in the present time of energy crisis.

Solar energy

But unfortunately, they don’t solely use the sun energy but a number of other chemicals are used in their working. This is making them cause pollution of several types. They also result in green house effect and thus in global warming.

Some of the solar thermal plants are designed that use natural gas or propane boilers other than the sun energy. This is used as a fuel to start up the units. It results in the production of the gases that cause the green house effect.

Energy Production Using Wind Farming

Tags: , , , , , , , , , , , , , , ,


Wind farming technology is now considered as a promising method for the production of energy. There are many techniques of energy production. Most of these techniques are suggested as the low cost energy producing ways. But nearly all these methods are involved in the CO2 and greenhouse gas emissions which are harmful for human health. More than 20 billion kilowatt of electricity power is now producing in United States with wind farming. This is considered to be enough for 4.9 million households. Two nuclear power plants or 40 coal fired power plants can also be produced the same amount of energy. However, nuclear and coal fires power plants are considered as insecure due to the safety and emission of green house gases respectively. Therefore, wind farming projects have now preferred for production of energy.

Reliable source of energy production

Wind power is now frequently used for the generation of home electricity. It is assumed that if this power is increased to ten times from the existing amount then it can produce electricity for 50 million homes. This would be enough for the 150 million people.

Energy requirements

Wind power can easily be covered the current overall requirements of energy. However, industry needs much power than the home requirements. Every coal fired production and emission of gases from buses, trains, cars and planes causes to pollute the environment.

Hydropower, or water-power is power that is generated from the energy of moving water, which may be harnessed for many useful purposes.

water am

Before the availability of commercial electric power became widespread, hydro power was used for irrigation, and used to operate various machines, such as watermills, textile machines, sawmills, dock cranes, and domestic lifts.

Hydropower is one of the oldest methods used to harness energy, and has been used for hundreds of years. Water wheels and watermills were built in India; water powered mills produced flour from grain in Imperial Rome, and were also used for sawing timber and stone.

The power generated from a wave of water released from a tank was used to extract the metal ores in a method known as hushing. This was extensively used in Britain in the Medieval and later periods to extract lead and tin ores. The same method later evolved into hydraulic mining when used during the California gold rush.

How Coal is Transported and Processed

Tags: , , , , , , , , , , , , , , , , , , , ,


Coal is transported all around United States by train; according to figures almost 70% of coal in 2007 was transported around United States through railroad. Barges and trucks contribution for coal transportation is 11% while rest is delivered mainly by tramway, conveyor belt, or slurry pipeline.

How Coal is transported

Sometime coal is transported great distances. Such as, Powder River Basin coal is transported by rail to power plants as far away as Georgia. It travels a long way as far as the distance from Wyoming to Georgia.

To save the money from coal transportation costs there is a common way that using coal near the coal-mines. As soon as the coal is mined it’s delivered immediately to power plant through conveyor belt. Such plants are called “mine mouth” plants. The growing presence of mine mouth plants had eased by expanding use of long distance electricity transmission.

Working of Geothermal Power Plants

For the generation of electricity Geothermal power plants use much higher temperature deep within the earth, we can say that these power plants are much similar to coal or oil powered generators in which electricity is generated from steam driven turbines.

One of the main difference is that coal and oil powered plants burn fossil fuels to produce steam while the heat of the earth’s core is used by the geothermal power plants. Earth’s core is extremely hot and some areas are more suitable for the generation geothermal power from others depending upon that how far the surface of hot areas are located in the within the earth.

There are many causes that lead to Global warming, with each of the reasons contributing more to the increasing intensity of the climate change that has affected our planet.

causes of global warming

The main cause of global warming is the increase rate of greenhouse gases present in the earth’s atmosphere. These gases cause the the greenhouse effect, which traps the heat present on the earth by reducing the level of solar rays that are able to escape from our atmosphere.

Although the greenhouse effect is extremely important to support life on earth, by keeping our atmosphere warm enough to support life, the addition of human activities contributing to the quantity of greenhouse gases has caused an artificial increase in the intensity of the greenhouse effect, which has made this great phenomena a bad effect. Thus greenhouse effect is not bad, it is the increase in the amount of greenhouse gases that are causing the harm.
