Renewable Energy

Sun is the source of the cheapest and the safer and cleaner form of power. Sunlight has most widely been utilized for a variety of purposes both on commercial and residential levels. Sun power is usable in all forms, in unprocessed form it has been helping mankind for various purposes like for laundry drying, crops rearing and for the sustainability of life. With the advances in technology, scientists started to use solar energy for various purposes by converting it into reusable energy.

Benefits of Solar Power Energy

Solar energy is far feasible than conventional energy. It is available at free of cost and it is renewable. Sun power energy is feasible for areas where there is a lot of full and strong sunlight, but have little electrical infrastructure. These areas can make most of sun power energy.

Downside of Solar Power Energy

The downside of solar power energy is that it is reliable only in those areas that receive full and strong sunlight. Sunlight cannot be collected and absorbed during night time. Also, a number of collectors are required in order to produce a little bit of solar energy. Despite of these setbacks, sun power energy still remains a popular source of the production of power among its counterparts.

Ways to Harness Solar Power Energy

There are various ways by which sun power energy can easily be harnessed, so it can be utilized in different things. Read the full story

The energy provided from sun is so strong that it can power the entire planet for one year. Surely we are clever enough to capture some of this magnificent force and use it to fuel our environment. Solar energy are divided into two categories, static or passive solar energy and dynamic or kinetic solar energy. An example of passive solar energy could be building a house so that the windows face the morning sun in cold climates. We do not know but our Earth uses the power from sun in many ways. Ours is an inherently rechargeable renewable world, provided we use our resources such as solar energy wisely.

For instance in case of shopping malls which use double paned insulated windows that allow light to enter yet keep heating or cooling locked inside. But what would happen if the sun moves away from the arc its following? Then active solar lighting can use mirrors that track with the sun’s movement and then reflect light into fiber optic cable that can carry that light into any part of our same department store. Further on, we can transfer warmth through various forms of solar energy. Like in the 1950s it was a common trend to see simple glass paned boxes filled with copper pipes which were used to help heat water for swimming pools and boilers.

We already know about the increasing hazards of climate change, but instead of accepting the disasters as nature’s revenge and continuing to burn fossil fuels into CO2, it is extremely important that we take appropriate steps to control the problems.

The rate of success will rely on our efforts and whether we are able to control the issue through scientific research, new public policies, and better personal choices that are environment friendly.

Here are some of the things that we can do to help towards the conservation of energy and environment and thus alter the increasing rate of climate change.

1. Walk instead of Drive

Try to walk or ride a bike for transportation. This way, you won’t just cut back on your fuel bills and generate less CO2, you’ll burn off that extra fat that, helping to reduce the risk of heart disease, high blood pressure, stroke, dementia, depression, colon cancer, and osteoporosis.

The officials at Sharp Manufacturing Co. of America have found a great way to save up some money and conserve natural resources while manufacturing renewable energy products. The firm will now be using solar energy in the manufacturing process of solar panels.

For this purpose, the Sharp plant in Southeast Memphis has launched the operation of Tennessee’s largest solar-power array.

Almost 800 solar panels covering an area of 12,000 square feet will cover the Sharp’s roof, generating a total of 150 kilowatts of power. Together with the 50-kilowatt system which is already being used, the power generated will be sufficient to run about 15 homes. However, this generated power is still very less to run the entire plant.

Although there are several advantages of solar energy but its high cost is the biggest barrier to its common use.

This high price may be due to various reasons including political and economic factors, but a big factor that contributes majorly towards the high price is technological cost.

Recently, the researchers at Caltech have successfully created a new material that will be used to make solar-panel, replacing the use of solar cells as we now use them.

Right now, there are two basic types of photovoltaic, or PV, cells that are in use. The first one is a solid silicon-based PV cell that although is very efficient, but it is very costly and fragile to make.

Though in last many years man has been setting new records of the progress that he has been making, however, he has paid a huge price for this progress and that has put his survival on the planet earth in danger. The way factories are coughing up the carbon venom in to the air, it has caused severe contamination in the air we breathe in.

However, now man has started realizing this problem and has started putting his efforts in correcting the mistake he has been making in last couple of centuries. An important thing that is increasing the pollution in the air is generation of energy through coal and oil. Instead of using the thermal or wind resources for producing electricity man has been relying upon the sources that are not only expensive but that are also dangerous for the health.

Wind energy is one of the fastest growing source of renewable energy in the world. Apart from being a clean power source, wind energy is one of the cheapest source of energy.

As the United States has plenty of wind, the use of wind energy can fairly reduce the country’s dependence on rapidly depleting natural resources.

Wind energy is not a new concept to generate power. Long ago, the Egyptians used wind energy to sail their ships on the Nile River over 5,000 years ago. In Persia, windmills were developed about 500 to 900 A.D. for grinding grains and pumping water. The same concept has been modernized to generate electricity.

Nowadays, windmills don’t just rely on the wind’s force to push the blades into motion in order to produce energy. Modern turbines use more complicated and refined aerodynamic principles to make use of the wind’s energy most efficiently.

The two basic aerodynamic forces that work together in wind-turbine rotors are lift, which acts perpendicular to the direction of wind flow; and drag, which acts parallel to the direction of wind flow.

The blades of a turbine are shaped just like airplane wings, using an airfoil design. One surface of the blade is a little rounded, whereas the other side is quite flat.

The Ocean waves has been proved as a great source of energy. The power of ocean waves can be utilized in an effective way to generate electricity to meet the demands of the rising energy crisis.

If you have a quick look on the globe, you’ll immediately notice that there’s a very small part of dry land, as compared to the water. The water covers almost 70 percent of the Earth’s surface. Thus if we can make use of this 70% to generate power for the people living on the 30% land, it will more than enough to meet all the daily needs.

Wave energy is about exploiting the phenomenal power of water waves. Waves have an enormous amount of unused energy, some of which can be used to power at least a portion of the world’s everyday electricity.

What is the purest form of power generation? The unanimous answer is Wind Energy. As Wind Energy has numerous benefits like no pollution, no burning of fossils and a clean setup. Although, it should not be perceived that it’s a facile setup unit. Various factors combine to make an impact on the amount of energy you can generate out of wind.

Power in the Wind

It’s vital to understand the relation of wind speed data with power production. Therefore, the power is proportional to the wind speed cubed. It is important to know the wind speed precisely, because any error is magnified when calculating power.
