PV Solar for Renewable Energy

Posted on 21st May 2010 in environment

In order to convert solar radiation to direct current electricity, it requires the use of PVs, or photovoltaic material. Many different types of material are combined to create the photovoltaic cell. Due to the most recent demand for renewable energy, the manufacture of these cells has dramatically increased. There production has been steadily increasing since 2002 each year. Read on and find out how PV solar is one way to conserve natural resources in the future.

Photovoltaics create solar power by using solar cells to convert the energy from the sun into electricity that we can use. They do this by the process of photovoltaic effect. This effect explains that photons of light roughly moving electrons into an higher state of energy that will then create the electricity. An inverter is necessary to convert the direct current (DC) electricity to alternating (AC) current.

Many materials are used to create photovoltaics. Some of the materials include different types of silicons, copper indium selenide, and cadmium telluride. Polycrystalline silicon is a key material of a solar panel. The supply of solar panels that can be created is limited to the supply of polycrystalline silicon, and in 2006, half of the supply in world was in use for solar panels. There were twelve known factories that were producing the material in 2008.

The production of PVs has increased by at least twenty percent per year beginning in 2002. That labels it as the fastest growing energy technology in the world. By the end of 2009, worldwide, installed PVs totaled more that 21,000 megawatts (megawatt=1 million watts).

Installing solar panels is being supported by many different countries. The governments of different countries are actually offering citizens and businesses alike different incentive packages to install them. New technology, and less expensive ways to manufacture have made the prices come down to a more affordable rate for everyone.

In 2008, it was said that solar power could provide one thousand times what the world would need and it only provide two tenths of a percent that year. By these statistics, it is apparent that renewable energy resources have not been used to the fullest; not even close. The prediction is that it will continue to double every two to three years. It could become the main power source for the world.

Some would say that solar power is not predictable, however, they are able to predict with exceptional accuracy when it will and will not be available. Other sources of renewable energy can also be used in conjunction with the photovoltaics. This has been proven successful in large power plants.

Do you Waste Water Every Time You Wash Your Car?

Posted on 20th May 2010 in environment

The process of car washing has been a huge drain on fresh, clean water and has had negative effects on the environment. This water could be used elsewhere and does not need to be flushed down our drains. On top of this, car wash chemicals are bad for the environment and can have negative effects on your car’s paint and finish. Is there a sustainable, environmentally friendly option?

There is a lot of talk these days about the wastage of the earth’s finite resources. One of the biggest subjects is the waste of petrol, but fresh, clean water is another important matter. The traditional method of thoroughly wetting your car and applying chemicals has been estimated to waste: in the home up to 530 litres a wash, and in the petrol stations up to 130 litres a wash. This a huge amount of fresh water without even considering any other fields that waste the same or more.

The chemicals used in these car washes are also a serious problem for the environment. Too often harmful chemicals are being used in bulk and flushed down street drains. Typical car washing chemicals can be very dangerous for the environment and can also effect the quality of your paint finish.

Waterless car washing products have been around for sometime. The big pushing factor for these environmentally friendly agents is that, as their name suggests, they directly cut down fresh water wastage by being 100% water free. This is done by using a formula that actively seeks dirt on your vehicle and provides a clean that is often more impressive than others washes.

And although this method obviously uses a chemical formula to remove the dirt, many products in the range are environmentally safe, biodegradable and wash off products that don’t get washed down drains and sewer systems.

Take another step into protecting your environment, and your vehicle, by moving away from traditional car wash methods and try out waterless car washers and car wash products.

Good Reasons to Buy and Shop Local

Posted on 15th May 2010 in environment

In many countries there is a wide selection of farming procedures. Between dairy farms and those that grow vegetables and fruits or increase chickens, it is possible to get the majority of your family food from local farms when you shop local. Farmers have a love of the land unlike others and are dedicated to taking care of the land and producing excellent crops and other foods. They love what they do, but certainly, they have to make sufficient profit from their own hard work in order to earn a good living and support their families. Local households and the community can help preserve the working farms by purchasing these types of goods.

Here are a few other reasons purchasing locally grown food makes sense: * Fresh as well as Yummy: The actual fruits and vegetables tend to be picked in the very peak of their quality. Cheese and other homemade farm products are prepared lovingly manually, without any preservatives or other poisonous, unpronounceable chemicals thrown in. Shop nearby farmer’s markets for endless variety.

* Good Quality: Favorite meats like chicken, veal, and beef are usually processed on the same land, or nearby. Farmers and their family easily supervise quality control to ensure consumers get the best and freshest product available when they shop local.

* Nutritious and Healthy: Nutrients are not lost in transportation, and the wellness value of the foods is not moderated by preservative chemicals when the products do not have to be trucked or even flown to far away destinations.

* Safety: Locally grown foods are safer for the neighborhood. Having the ability to meet the farmer and speak with those that have produced the crops or raised the actual animals, or his wife who made the actual cheddar cheese, lemon cookies, or cherry pies for tonight’s dinner brings with it a sense of belief in the community. They are not anonymous strangers; these people live and work inside the neighborhood.

* Protect open areas: Farmers who’re producing and making a profit by working on their farms will likely keep doing so. Purchasing local is really a proactive way to help preserve the fabric of the community, in terms of the families working presently there and the available spaces that are today’s operating farms. The lucrative farm will generally not be offered to a real estate developer and subdivided, and that maintains the appearance and feel of the community.

* Benefits animals: Great farms as well as farmers preserve and enhance the fertile dirt and protect the neighborhood drinking water assets. Environmental surroundings on the land today remains much as it had been 100 years ago. Farmers do have use of better gear nowadays, though a lot of it is priced beyond reach for smaller farms. The fields, channels, wooded places, ponds, and out-buildings give excellent environs for animals within our communities, as that has been decreased by building of all types.

As you can see, in your area produced food is a win-win situation for everyone involved, so please try to purchase as much in your area produced food as possible.
