While both the demand for energy and energy prices continue to increase, nonrenewable sources of energy, particularly fossil fuels, are decreasing. These factors, coupled with the effects of pollution and global warming, are driving consumers and industry to call for a better solution to the world's energy needs.
Some suggest that the solution might be found by making innovative technological improvements to an existing source of energy- nuclear power. Currently, nuclear power supplies 16 percent of the world's energy.
Unlike coal, natural gas, or oil-all nonrenewable and subject to price volatility-nuclear power plants are fueled by uranium, a relatively abundant element that occurs naturally in the earth's crust. Plus, nuclear energy is the world's largest source of emission-free energy. Nuclear power plants produce no controlled air pollut-ants or greenhouse gases.
One of the latest developments in the production of nuclear energy comes from Westinghouse Electric Company. It has introduced what's been described as the safest and most economical nuclear power plant available in the worldwide commercial marketplace-the AP1000. It's the first reactor of its class to receive Design Certification from the Nuclear Regulatory Commission.
Based on 20 years of research and development, the reactor builds on the proven technology of major components used in current Westinghouse-designed plants. These components include steam generators, digital instrumentation and controls, fuel, reactor coolant pumps and integrated engineering-and have years of reliable operating experience.
Using this established technology as a jumping-off point, the innovative design of the reactor is said to offer distinct advantages over other reactors-including unequaled safety, economic competitiveness and improved and more efficient operations.
The AP1000's innovative approach to safety reduces the need for human intervention and the potential for human error. Its simplified construction design can lead to significant savings in plant costs and an accelerated construction schedule.

13 SEER & Earth Day: Working Together To Improve the Environment
The 35th anniversary of Earth Day will take place on April 22. Through the combined efforts of government, grassroots organizations and environmentally minded companies, Earth Day has evolved into a worldwide campaign to protect the global environment.
In the U.S., the Department of Energy (DOE) is also concerned about protecting our environment and resources. To address these issues, the DOE recently issued a mandate that now requires all new, central air conditioners manufactured after January 23, 2006, to have a seasonal energy efficiency ratio (SEER) of at least 13. SEER is a number similar to miles-per-gallon in cars; the higher the SEER, the more efficient your air-conditioning system.
According to the DOE, the 13 SEER standard is forecasted to save the nation 4.2 quads (quadrillion British Thermal Units) of energy over 25 years (2006 through 2030). This is equivalent to the energy consumed by nearly 26 million American households in one year. The standards are also expected to save consumers $1 billion over the same period.*
Manufacturers like the Unitary Products Group of York-a Johnson Controls Company, haven't stopped at 13 SEER. York® also offers new home-cooling systems that reach 15 and even 18 SEER.
Much of the improved efficiency associated with 13 SEER units is the result of an increase in the surface of the coil found in a system's outdoor unit, which is used to transport refrigerant. As a result, these outdoor units can be 50 to 90 percent larger than 10 SEER units and require as much as 40 percent more refrigerant than many indoor coils are capable of holding. It becomes very important, then, to match the size of the indoor coil with the new, larger outdoor unit.
A mismatched system can lead to lower comfort levels, a higher utility bill, increased stress on the system and large repair costs. A qualified dealer can make sure your system is matched and installed correctly and is efficient and economical to operate.
So, if you are considering replacing or upgrading the HVAC system in your home, talk to the experts at York. They can help you select a qualified dealer, who is equipped to maintain, repair and/or replace the components of your system.

10 reasons to buy a hybrid car
Care for the environment? Want to save the planet? Then you must think in terms of fuel efficiency, non-polluting, and eco-friendly transport. The answer lies in purchasing and using a hybrid car. They not just make a statement that I care but are compact and fuel efficient.
Here are some insights that may just tempt you to buy a hybrid.
1. Made of lightweight materials hybrids are small in size. The engine is designed to be fuel efficient. When the car halts at a signal, the engine will automatically shut down and restart when the car shifts into gear.
2. These cars have the advantage of being powered by a gasoline engine and an electric motor that takes care of acceleration.
3. The batteries of the electric motor recharge automatically by harnessing the kinetic energy produced during braking.
4. Hybrid car engines produce less emission, give better mileage, idle less, and are fuel efficient.
5. The aerodynamic design reduces drag and the tires are made of a special rubber that reduces friction.
6. The battery has high capacity and is made of nickel-metal-hydride. The battery can run the hybrid when called for.
7. The power-train technology enables using two power sources and enhances fuel efficacy.
8. There are many choices. You can have a hybrid from Honda, Ford, Toyota, GMC, and Chevrolet.
9. If your transportation of choice is a hybrid then the US Government will applaud your choice by giving you significant tax breaks.
10. Using a hybrid means you are active in ensuring the air is clean and that you are a concerned citizen who wishes to save fuel which is precious.
Maximize usage by “pulse and glide.” This means finding the ideal point where electric and gas energy are equally utilized. Generally this ideal lies between 30-40 miles per hour. Stabilization of energy is learnt by practice it really cannot be taught. Another important aspect is that you benefit if you don’t rush around and drive at the prescribed speed limit. If you glide, instead of accelerate then you can make a saving of as much as 10 cents a gallon. Lastly check and maintain tire pressures. This will help lengthen the life of the tires and help you save fuel. Reduced tire pressure studies indicate reduces gas mileage by as much as 10%.
Before you say “yes” to buying a hybrid car, you must do in depth research on hybrids, the pros and cons. Talk to manufacturers and owners. Test drive the different makes and check which one would suit your life-style. Some hybrids are ideal for city driving while others are more efficient on open roads.
Even if the buying price is steep the fuel that you save along with incentives like tax breaks make a hybrid a good and sensible choice.

5 Great Reasons To Harness Solar Power
Very simply put, ‘Solar energy’ is energy that is derived from the sun. Our sun is an abundant source of energy; it gives of heat and light. The sun’s been revered by several cultures of the past and even by a few cultures still present today. The ancient Egyptians even worshiped the sun as a God.
All said and done, it was not misplaced respect; the sun certainly is an abundant and limitless source of power, at least for several generations to come; the merits for using its solar energy are numerous.
It’s free
Every morning with each dawn, the solar energy released by the sun comes filtered through our atmosphere providing light and helping to radiate heat. This has been happening for millions of years yet it is only recently that we have begun to capitalize on this abundant source of almost infinite power.
In the past the Greeks and the Egyptians have been known to harness the power of the sun to heat whatever they wished to by concentrating its radiation.
It’s non-polluting
The energy from the sun is clean and free of any pollutants; unlike various sources of energy present today like petroleum or organic fuels that leave back residues and often leave back harmful gases when utilized to create energy.
Extremely reliable
The sun has been burning for roughly four and a half billion years now and is likely to burn on for another four to five billion years to come. That’s definitely more than our lifetimes and certainly more than several generations of the future. Every morning it promptly shows up and vanishes for the evening while it lights up another portion of the globe.
The saying “as sure as day” did not come about for nothing; assuming the sun is shining brightly, depending on which part of the globe you are you can harness the energy of the sun to either store it away or utilize its energy in a different way.
Limitless
There is no restriction on how much energy we can use from the sun. Apparently, the amount of energy that comes from the sun every few minutes if successfully harnessed can power the entire United States of America for a whole year. If we were only able to harness the immense energy of the sun we would be able to solve all the worlds’ energy problems.
Why
Ever wonder why no one thought about this earlier? How come if there’s so much energy just lying around, we simply cannot seem to efficiently harness it? How it that so much of the sun energy seems to go totally unnoticed and is ultimately wasted?
Well one of the reasons that this wonderful power reserve is generally wasted is the fact that the sunlight that we actually receive is so thinly dissipated across the earth to be able to contribute substantially enough if we try to harness it.
For us to be able to actually harness the power of the sun we have to be able to manipulate, focus and store the sun's energy. While this may seem simple it is easier said than done; So far we have only managed to develop three partially successful means of collecting solar energy.
The Reflection Method – Mirrors / Parabola
The reflection method is based on the concentration of the sun’s rays through a single or a set of mirrors onto one point and then utilizing the concentrated heat energy that is produced for out need. A parabolic mirror much like a dish antenna can be used to capture the sun’s rays and focus them on a single point.
The radiation method
This is the principle behind the solar water heaters. Painted black pipes sandwiched between two layers of glass, have water inside them that is heated thanks to the rays of the sun.
Solar panels
A more recent invention the ‘solar cell’ is composed of treated silicon crystals, which when hit by the rays of the sun knock electrons out of their orbits and thereby create a void that needs to be filled by electrons from the other silicon crystals, this creates an imbalance of electrons and hence a flow of current which can be either immediately utilized or else stored away in a rechargeable battery.
What’s stopping us?
Despite the apparent benefits of using solar power it is most unfortunate that there are very few solar power plants around the world. Sadly, with today’s level of technology, cost and reliability are two major factors that are still hurdles in the way of mass usage of solar energy.
Technological limitations dictate that the most efficient solar cells created today are still not capable of generating enough power to be commercially viable without occupying huge surface areas. Furthermore, reliance exclusively on solar cells in not yet practical, for if there were to be a cloudy day it could reduce the amount of electricity generated and that would be disastrous for those people completely reliant on that energy.
On the bright side, constant innovation and research on solar energy is resulting in much more efficient solar cells that are a fraction of the size of existing cells and churn out much more power. For now they are still expensive, but not far is the day when they will be affordable and available to the common man.

“Don’t Touch It,” and other simple, nature-friendly advice
Each summer, I visit the Chequamagon National Forest in Wisconsin. An amazingly beautiful and lush forest, this place is my sanctuary. I stay at a low-key resort, in a cabin overlooking Lake Namekagon. It’s a breath of fresh air - quite literally - to spend two weeks each year at this place, away from bustling streets and busy people. It’s like a different world.
Or, at least, it was. I had a very different experience this past July. Upon entering our cabin, my fiance and I were greeted by a large television, equipped with Direct TV. Don’t get me wrong: I’m a TV-lover, through and through. There was, however, something strange about having to look around the television to see the lake.
We overlooked this; after all, we don’t own the cabin. Some resort-goers might crave 500 channels before they crave hiking and fishing. Convinced that the TV (both the sight of it and the temptation to watch it) would put a damper on things, we went out on the water.
As I started the old, rented pontoon boat, something occured to me. We were no better than the TLC, MTV, and MSNBC addicts. Yes, our boat was used for the enjoyment of the outdoors; however, it left a muddy, green wake behind it. Yes, we came to the resort to get away from everyday conveniences and to surround ourselves with nature, but we were staying in a cabin - not a tent or a sleeping bag. We cooked our breakfast every morning on a fairly modern stove, we drank coffee made in a Bunn coffeemaker, and we turned on the electric heat if the cabin got too cold. It turns out we weren’t roughing it; we were faking it.
Since this realization, I’ve been troubled. I don’t understand where our appreciation for nature went. I don’t understand how misguided travelers - myself included - consider themselves to be experiencing nature, when really all we’re doing is glancing at it between commercials. Granted, everyone experiences nature in a different way. For some, glancing at it through a window - or on a TV screen - might be enough.
I’m concerned, though, that by accepting this as a legitimate way to experience nature, we are missing something. Or, perhaps, we are missing everything. On a basic level, there is something satisfying about feeling a different kind of air on your skin, and about feeling the crunch of leaves and dirt beneath your feet. Where city lights don’t corrupt the night sky, we can see stars in a new way, and the level of darkness is foreign and exciting.
There more to this simple human/nature combination than deep satisfaction, though. There is a danger present in the ways we currently explore nature. It is common for travelers to hop on boats, jetskis, waverunners, or ATVs to travel through lakes and forests. In these cases, vacationgoers are experiencing nature - while leaving a trail of pollution behind.
And what about our cabin? Built in the middle of the forest, trees had to be removed in order for the resort to exist. There is an inherent disconnect, here: the resort was designed to house nature-loving travelers who want to see the forest’s natural beauty, and yet in order for the resort to exist, some of the forest had to be cut down. Instead of experiencing untouched and unscathed nature, vacationers are experiencing a forest marred by human interference.
This is the way with us. We, whether intentionally or accidentally, can’t help but tinker with nature in its natural forms. Even when we attempt to truly experience it, we are also hindering it. So, we must consider some simple pieces of advice if we wish....(read the full article at the link below)
