What is Solar Energy?

Sun is the ultimate source of energy. The Energy obtained from sunlight is called Solar Energy. The sunlight is a renewable source of energy which is freely and abundantly available, like other natural sources of energy for example: wind, water.

The Solar Energy can be classified in two main categories depending on its uses:
a)    Solar Active (Direct Conversion)
b)    Solar Passive (Indirect Conversion)

a) Solar active: In this category the solar energy is directly converted for its usefulness. It is converted to Solar Thermal and Solar Photovoltaic.

Solar Thermal also known for Heating Application is used to collect and convert sun energy to heat energy. This application is useful for heating water, air and is used for cooking, drying, steam generation etc..

Solar Photovoltaic is direct conversion of solar energy to electrical energy by using Solar Silicon Cell. The electricity generated is used directly or through battery storage system, these are widely used in rural areas for lighting purposes. The villages that do not enjoy the power facility are provided electricity through solar photovoltaic cells.

b) Solar Passive energy is used buildings where these are installed so as to maximum utilize the solar energy. The Electricity generated is used for various purposes like lighting homes, air conditioning, water heating etc…

Thus, the energy derived from the sun is in form of Heat and in form of Light. You need to install Solar Panels on the roofs of your houses or your building terrace. These Solar Panels convert sun’s energy to DC Current and the inverter changes DC Current to AC Current, which is widely used by you home appliances, like television, computer, lamps, fans, lights, refrigerators etc.. This technology may require a lot of investment, initially, but later on prove to be cost-effective method.

Solar Energy has enormous uses like:
1.    Heating water: With the help of Solar Water Heater, Solar Energy is widely used to heat your water supply and swimming pool too. Solar water heaters have 2 main parts that are solar collectors and storage tanks.
2.    For Cooking: Solar cookers available widely help to generate a lot of thermal energy required for cooking. The heat helps to cook food in solar cookers.
3.    Photovoltaic Solar Cells that convert sunlight to electricity directly is used to operate wrist watches, calculators and also some complex systems are used to light houses.
4.    Passive solar heating systems do not need solar collector. These are used in buildings and are installed in walls and floors in such a way that it absorbs heat and warms up buildings. This helps to keep rooms warmer and well lit, reducing electricity bills.

Solar Energy which is abundantly available is not only useful but also cost-effective.

These are more eco-friendly as it does not emit harmful gases during conversion of solar energy to thermal or electric energy.

The best method to trap solar energy and convert it further to desired purposes is the use of solar bars. These are more eco-friendly and absorbs a good amount of heat required for conversion. They are nothing but New Solar Reflective Roof System with Solar panel. The invention of first Solar Bar, which has a cutting edge on technology, has worked wonders and given results beyond imagination.

Thus, it is recommended to understand and use solar energy which is a renewable source of energy and is a natural resource which will always be there for a lifetime.

To avail its benefits and to cut down on our electric costs it is advisable to use Solar Energy, which initially requires a bit of installation expense, but later on is economic and beneficial throughout.

At gives you the worlds first solar powered bar To know more about enormous uses of solar energy that is cost effective and helps to cut down your electric expenses, using latest solar energy bars solar energy bars at 3nicksbars.com.

Obama’s Plans for Hybrid Cars

President-elect Barack Obama recognizes the need to address the most common problems of the environment, including America’s dependence on oil. He has identified hybrid cars as the way of the future, the development of which will reduce our dependence on foreign oil, reduce greenhouse gas emissions, and revitalize the American auto manufacturing industry.

How exactly can change be brought about? Isn’t the problem too bigger than just driving hybrid cars? Probably. But, no change can be instilled overnight. While there are never any guarantees on what propositions will or will not work, Obama has suggested a few changes that may help wean America from its gas guzzling ways.

1 Million Plug-In Hybrids by 2015
While this is a lofty number to reach within just a few years, it shows Obama’s dedication to making serious changes within the auto industry, for our sake and the environment’s sake. Taking the idea of hybrids a step further, there have been new car models made that will charge by plugging them in. These plug-in hybrids do what you might expect. They run on gasoline and rechargeable batteries. At the end of the day, when you get home, you simply “plug-in” your car to an electrical source so it can charge while you sleep. No more stopping at the gas station to get your fuel needle off of E in order for you to make it home. You simply plug your car in from the convenience of your own home. These cars could potentially get 150 mpg, saving the driver enormous amounts of money on gasoline and saving the ecosystem from damages of harmful emissions.

2. Tax Credit for Plug-in Vehicle Consumers
Plug-in vehicles are still in the developmental stages but show promise for enabling cars to run on electricity rather than expensive and environmentally harmful gasoline. Obama has suggested tax credits for consumers who take advantage of the opportunity to drive these cars while they are still new to the market. With initial this buy in, the future of plug-in cars may be closer than some people think.

3. A Law Requiring All Vehicles Made Flex-Fuel Capable
Flexible-fuel vehicles, or sometimes called dual-fuel vehicles, are cars that run on a mixture of energy fuels. Most flex-fuel vehicles use some gasoline to run in addition to either ethanol or methanol, both fuels are found to be more environmentally friendly than gasoline. The idea of dual-fuel vehicles is not a new idea. The Ford Model T that was produced from 1908 to 1927 ran on both gasoline and ethanol. Because ethanol was prohibited for much of the 20th century, ethanol fueled vehicles are still being developed. With the proper safety precautions, ethanol may be proven to be a great alternative to gasoline in time.

4. Tax Cuts for Auto Manufacturing Plants
Obama has proposed to offer tax cuts to automakers in order to stimulate the auto manufacturing industry. He hopes that by doing this, plants will be able to reach better fuel efficiency standards in the future.

Green transportation is a challenging front to tackle, but something that must be done in order to stall or perhaps one day reverse the damage caused by the irresponsible fueling practices of the last hundred years. If we start by instituting these relatively small changes, there may be hope for change.

Obama has done some work in this area over the last few years already. He issued The Health Care for Hybrids Act in 2006, which was used in Illinois and Washington state. With the further weakening of the economy since 2006, Obama may need to reevaluate his former laws. It’s possible that even more drastic measures need to be taken in order to salvage the auto industry across the US. If gas prices continue to fall as they have over the last few months, people may ignore the fact that hybrid and fuel-efficient cars are extremely necessary for saving the environment. We must encourage people to look beyond themselves and see how they impact their surrounding environment.

The American citizens elected Barack Obama the next president of the United States because they are eager for change to take place across the country. Our perspectives on cars and fuel efficiency are one of the foundational principles that need reexamined and Obama appears to be considering this already. By simply taking a closer look at purchasing a hybrid for your next car, you could be helping the country move a step closer to reducing our dependence on oil.

Toyota Greensburg provides new and used cars that are recognized as environment friendly and fuel efficient. The EPA and the US Department of Energy recognizes the Toyota Prius as having the best gas mileage of any car on the market in the 2009 Fuel Economy Guide.
