Wind Energy - USA

Solar Rick

2006-09-30

		Title: Wind Energy - USA

As oil prices continue to explode, alternative energy is getting a close look in the United States. Here is a guide to wind energy in the USA.

Wind Energy – USA

One of the world's fastest growing types of renewable energy sources is wind energy. While most of the Earth is still reliant on different types of fossil fuels (such as oil, natural gas and coal) for their energy supply, many countries are trying to come up with alternative methods of obtaining energy. Much of Europe has begun to build and use wind farms, which are groupings of wind turbines that harness the energy of the wind in order to create energy and electricity. Also involved in using wind energy, USA has started to build their own wind farms.

Wind turbines are the individual components of wind farms, and they are machinery composed of several main parts. The first part is the rotor, also known as the blades or the propeller, and this is the part of the turbine that actually collects the wind energy and converts it into drive energy, which then turns a shaft. This shaft actually creates the energy that is then stored or converted into electricity. Wind farms are groupings of many of these turbines, usually 10 or more.

The wind energy USA had capacity for in the year 2004 was 6,740 MW, with a prediction that the wind energy capabilities of the United States will be increased by 5,000 MW in the next five years. The US Department of Energy has a goal of obtaining 6 percent of the country's electricity needs from wind energy by the year 2020, which is a fair goal judging by the current rate of growth seen in the wind energy industry. California is the state in the US that produces the most wind energy, with 2,096 MW of wind generating capacity per year.

As one MW is enough energy to supply energy to 240 to 300 average US homes, the amount of wind energy USA currently produces is enough to energy 500,000 to 620,000 homes per year. The United States is currently ranked as the third highest wind energy producing country in the world, behind Germany and Spain. The business of wind energy in the US is also monetarily significant – it costs about $1,000 per kilowatt (KW) of installed wind energy capacity. When multiplied by the US's capacity of 6,740 KW, this makes wind energy a $7 billion industry.

Wind energy is a growing energy source in the United States for many reasons. Wind energy is cleaner, cheaper and more renewable than many of the current sources of energy used in this country. Additionally, the capacity for expansion of wind farms and ways to harness wind energy means that as the US's energy needs grow, there will continue to be enough energy to provide for all of our energy needs.

Do Energy Drinks Really Give You Energy, or Just a Fat Stomach

		Title: Do Energy Drinks Really Give You Energy, or Just a Fat Stomach

I receive a ton of questions about all of these new "energy" drinks that have hit the market over the last few years. They seem to be all the rage, especially with the youth, and they promise you the world with outrageous claims of all of the super energy that you are going to have, and how you'll be crushing the competition in your sport, and so on.

So a couple questions arise:

Are these "energy" drinks really any good for you? Do they actually increase your energy? Do they really have some sort of magical energy formula? Will they help you lose weight?

First of all, let's look at what most of these energy drinks are usually made of. Most of them are simply carbonated water loaded with gut-fattening high fructose corn syrup, caffeine, the amino acid taurine, and a few random B-vitamins thrown in for show to trick you into thinking there's something healthy about these concoctions.

Let's start with the high fructose corn syrup. Well, here we've got empty calories that will go straight to your belly fat, and that are actually even WORSE for you than plain old refined sugar.

Ok, so you say that they have low-sugar or sugar-free varieties as an alternative to the HFCS-laden energy drinks. Yes, but now you have the problem of the harmful chemicals in the artificial sweeteners.

Another problem with artificial sweeteners is that there are some researchers that believe artificial sweetener use leads people to inadvertently consume more calories and gain more weight in the long run. I won't go into the details on that because that would fill up an entire discussion by itself. Just trust me that artificial sweeteners and artificial chemicals in food in general, are all bad news for your body!

What about the caffeine? Well, first of all, caffeine in itself doesn't provide "energy". Technically, the only substances that actually provide energy are calories (from carbs, protein, and fat).

However, caffeine can be an aid for livening or waking some people up, by means of stimulating the central nervous system. Keep in mind though, if you're a regular coffee drinker, you're probably addicted to caffeine and probably wouldn't receive too much benefit from the caffeine in an energy drink anyway.

Besides, instead of caffeine added to some carbonated drink, I'd rather get my caffeine from a natural source like green, white, or oolong teas, which actually provide healthful antioxidants too!

Now what about that so called magical blend of taurine and B-vitamins that they load into these energy drinks? Well, big deal...you can get taurine in almost any protein source. And the vast majority of those B-vitamins are simply coming right out into the toilet in your pee. Vitamins are best obtained naturally from real food sources, not artificially added to some carbonated drink. Your body just doesn't use fake sources of vitamins as readily as natural sources from real food.

So as you can see, in my opinion, I give all of these energy drinks a big time THUMBS DOWN! You're better off mixing up your own homemade energy drink with some iced unsweetened green, white, and oolong teas, a little bit of 100% pure berry or pomegranate juice, and maybe a touch of a non-denatured whey protein.

Well, I hope this article cleared up some of the confusion about these energy drinks that are being so heavily marketed these days, and will help you make more informed decisions for your health. Check out Mike's Truth about 6-Pack Abdominals Program at TruthAboutAbs.com

Solar Energy Overview

Solar Rick

2006-03-28

		Title: Solar Energy Overview

Solar energy is a renewable, clean energy that has been around for thousands of years in one form or another. Following is an overview of solar energy.

Solar Energy Overview

Solar energy is all about harnessing the power of the sun to produce energy. The sun rains enough solar energy on the Earth in one day to power the entire energy needs of the world for one year. Solar energy is considered a renewable energy source because it will exist for as long as our sun does, estimated to be another 4.5 billion years. Solar energy is also considered a clean energy because it does not produce pollutants or byproducts harmful to the environment.

Solar energy was the first energy source used by mankind. Of course, the use was limited to drying things and heating caused by direct contact, but it was a use. In modern times, solar energy has been a power source since the early 1950s, but was not widespread due to technological issues which rendered it an ineffective and expensive energy source. With technology advancements, solar energy is moving to the forefront as a potential alternative to fossil fuels.

The future is indeed bright for solar energy as new solar nanotechnology is close to creating solar platforms that boggle the mind. For instance, a few companies are trying to create solar quantum dots, which will be mixed in the paint you use for your home. Yes, you will actually paint on solar energy panels that will power your home

Currently, solar energy is produced primarily through the use of solar cells, also known as photovoltaic cells. The process works by placing the cells in direct sunlight. Sun hits the cells causing a chemical reaction that creates an electric current. The current is then turned into electricity. The problem with these cells, however, is they are only about 15 percent efficient.

Solar energy is typically classified in two ways, passive solar and active solar. Both approaches produce solar energy, but in very different ways

Passive solar is exactly what it sounds like. It does not involve panel systems or other moving mechanisms to produce solar energy. Instead, passive solar involves planning a structure in such a way as to capture the power of the sun with windows, tanks and so on. These systems can be used to heat homes, water and so on.

Active solar energy systems typically involve some form of solar panels. The panels are oriented to maximize exposure to the sun. Depending on the system, the panels will then either directly convert sunlight to electricity, which is then transformed from direct current electricity to alternate current electricity and stored in batteries or fed into the grid system of the local utility. Active systems are more expensive and complex.

Solar energy has numerous advantages over other energy platforms. It is produces no pollution, requires little maintenance and comes with significant financial incentives in the form of tax deductions, tax credits and rebates from manufactures. In a majority of states, solar energy can also be sold back to utilities per a concept known as net metering. This reduces the need for batteries and significantly cuts utility bills.

Unfortunately, solar energy has some disadvantages as well. The initial cost of purchase and installation can be expensive. Second, areas with limited sunlight are problematic. Third, solar energy obviously can’t be produced at night. Despite these disadvantages, solar energy is a booming energy platform.

The largest producers of solar energy in the world are Germany, Japan and the United States. California has recently introduces a solar initiative devoting over three billion dollars to promoting solar energy use by residents in the state. As this overview demonstrates, the solar energy platform is coming on strong.

ACTIVATE THE ENERGY OF THE UNIVERSE

Ineke Van Lint

2006-03-02

		Title: ACTIVATE THE ENERGY OF THE UNIVERSE

Did you know that you can not create energy yourself?

You can just activate the universal energy, which exists always and will always exist. This Energy gave you life. It’s always there, at every moment, for everyone.

There is no such thing like people with a lot of energy and other ones without energy.

The difference is that energetic people know how to activate this always available energy. And the low energy people, they block this energy, which is although always available for them too!

Energy does not decide something like :”Hey I like this one so I will send her energy, and the other one over there I don’t like so he won’t get any of my energy”. This is nonsense! The same counts for diseases. A disease does not “choose” a body to attack. How would it do it? Can you imagine a cancer saying : “I don’t like the way he cuts his hair, so I will attack his liver?” or “I can’t stand the way she talks so I will attack her breast?”

There is no such thing. It would be absurd. We have much more to say to our body and our life than we can understand for now or than we will want to admit for ourselves. Because to understand this is to take responsibility. Once we know that we “ask” for disease - by thinking of it all the time, by running from one doctor to another, by reading all articles about diseases in magazines, by telling our friends and family about all our pains and troubles - than we have to change our behavior and start to behave like a healthy person, who tries to understand why he got ill, and tries to see how he can change his way of thinking and handling to stay healthy.

It’s much the same for energy. Energy is always there. It never goes away, it never slows down, otherwise our whole galaxy would fall apart. The same energy which holds the stars at place in the sky, which makes grass grow and turn the earth on his own axis, is available for us. Can you imagine? It’s tremendous and there for us!

You can activate this energy for you by thinking the right thoughts, that is thoughts which stimulate you instead of turning you down, thoughts which bring you health instead of disease, thoughts which make you feel loved instead of fearing loneliness, thoughts which bring you wealth instead of poverty.

Is thinking about all this nice stuff enough to bring it into your life? No! Otherwise it would be so easy just to lean back and think about everything you want and floops….it’s there! We all would be fairies and make the world whatever we want without doing anything.

Luckily it doesn’t work like that! It would be dangerous! We need something else to make our thoughts create what we want : it is action. The combination of both will give us what we want : dreaming about what we want and putting ourselves into action, that is taking steps in the direction of our thoughts.

At each step we take, the universe also takes a step toward us. By our thoughts and our actions we activate this enormous universal energy to work for us. We make it move in the direction of realizing our dreams.

So the formula is pretty simple : first you dream, than you take action in the direction of your dream. This will generate energy to help you take the next step. The energy generated by this step will help you take the next step. And so on….

How do you know which action to take? Follow your guts, follow your intuïtion. It’s the best guide you can find!

Stop worrying. Instead dream, think of what you want and get yourself moving in the direction of your dream. That’s it. Watch what’s happening. Let the mystery unfold itself.

Changing The Course Of Energy

2007-11-17

		Title: Changing The Course Of Energy

If you are ever wanted to immerse yourself in the world of energy courses and learning about green energy and energy efficiency, there is not better place than the sunny world of Arizona. Here - in fact, all over the state – youll find many solar energy courses, for example. This renewable energy from the sun is the subject of the following sampling of Arizona energy courses.

At Arizona State University one energy courses teaches students about building environmental ratings systems. This is one of the energy courses that actually prepare its students to become certified solar energy assessors.

The premise behind this energy course is that buildings, both residential and commercial, have a significant impact on our environment. The construction of buildings uses up 40 percent of the worlds gravel, sand and stone each year and one fourth of its virgin wood. In the United States alone the use of, construction of and demolition of buildings accounts for almost 45 percent of the countries domestic use of energy. This works out to approximately 10 percent of the global use of energy. What this means is that this U.S. practice significantly contributes to harmful greenhouse gas production. In fact, its impact and volume is about equal to the entire municipal garbage production of the country. In 30 percent of these buildings the air is unhealthy.

This energy course teaches the responsibility that architects and other design professionals play in preserving our environment and making it more energy efficient. Converting this responsibility into a detailed system of environmental ratings is the subject of this energy course. Studied in the course is the United States Leadership in Energy and Environmental Design System LEED, part of the federal Green Building Councils energy efficiency program.

This energy course should give students an excellent understanding of LEED, and prepare them to pass its certificate exam.

Graduate ASU students can actually come away with a Masters in environmental technology. The degree called a Masters in Technology, grants a concentration in the management of environmental technology. All the graduate energy courses are Internet based. Three concentrations are offered: emergency management, environmental management or the more expansive international environment management. The program is ongoing for a total of 24 months, beginning in January and ending in December.

Additional energy courses include the design of photovoltaic systems, the analysis of building energy, energy analysis and technique, environment control systems, and the evaluation of experiments. The study of photovoltaic systems, for instance is an energy course that looks at the design of system that may or may not provide for storage of energy, and that may or may not have investors. It looks at grid-connected and standalone systems, as well as discussions about hybrid energy systems.

Energy courses that look at the analysis of buildings energy use include computer simulations of the thermal behaviour of buildings, a review of the software that can help with the analysis and evaluation, and a detailed look at various simulation models and case studies. Laboratory work is part of this energy course.

Alternative Energy Uses

		Title: Alternative Energy Uses

Everyone knows we are experiencing an energy crisis. You'd have to have your head in the sand to miss all the news about what we need to do to save our resources for our children, and our grandchildren. I absolutely agree that we need to conserve for the sake of our planet. However, I want to talk about a more personal kind of energy crisis, for a different (but no less pressing) cause.

What about our emotional and psychological resources? The resources we waste wondering: am I eating the right foods? Am I doing the right exercises? Do I exercise enough? Do I look the way the magazines say I'm supposed to?

My cousin once told me at her work the employees discuss their diets and their bodies on a regular basis. They will sit at meals, talk about the foods they have brought, and the reasons they should be eating something else. They talk about how they wish they could fit into their old clothes, and how they don't like the way their bodies look. This struck me as so very sad, and all I could think was, "What a waste of energy!"�

Why do people do this to themselves? I'm afraid we are caught up in a vicious cycle. We are caught in thinking about the way we are "supposed to look, supposed to eat"� - and when we possibly deviate from a given, we have committed a sin, and there is no going back. What is it in our nature that forbids us to allow ourselves to simply do the best we can with the resources we have, including time to cook, to buy food, to be active, and most importantly, to accept ourselves?

Why does it seem to be easier to criticize what we haven't done, rather than congratulate ourselves on what we have managed to accomplish in a society where we are rushed, rushed, rushed? Why aren't we able to congratulate ourselves for being able to take a ten-minute walk during our break, instead of criticizing ourselves for not going out and jogging for 45 minutes?

I don't know the answer to this yet, but I do like to imagine what could be done with the time and energy saved on not being critical of ourselves.

One way we can conserve our emotional and psychological energy is to learn to be at peace with food. You need to learn about yourself and why you have the relationship you do with the food you eat. Once you are able to do this, you will not need to waste time wondering about your food choices, or your exercise activities, or the way you are "supposed to" be.

Imagine if you discussed with your friends and colleagues life, politics (okay, everyone isn't like me and won't do that), travel, good restaurants, and books. Imagine the lively conversations about the latest Harry Potter (beware: spoiler alert!). Didn't you just know that Snape was a good guy all along?

Think of all the things you would learn about yourself and your friends if you just weren't wasting energy.

An Overview Of Solar Energy And Other Renewable Energy Sources

2007-05-11

		Title: An Overview Of Solar Energy And Other Renewable Energy Sources

When we talk about renewable energy we are referring to power that delivers energy from resources that will not be depleted because of our use of them. Renewable energy is an alternative to non-renewable fossil fuel energy for reasons other than the factor of non-depletion.

One basic benefit of renewable energy, and the reason environmentalists all over the globe are advocate its use, is that it does give off greenhouse gases and other harmful pollutants as do the by-products of burning fossil fuel for energy. Renewable energy such as solar power, water power and wind power, while the widespread discussion of which is new, are anything but new.

In both newly developing and highly developed countries wind, sun and water have long been used as power sources, though not to the extent of providing the primary energy source for large metropolitan communities.

The mass production of such renewable energy is become commonplace in recent years as more and more people come to realize how climate is changing due to the pollution of fossil fuel gases, due to the exhaustion of the availability of these fossil fuels and the political and social concerns of energy sources such as nuclear power.

Many countries and non-profit environmentally-conscious organizations are encouraging the use of renewable energy sources by passing legislation on tax incentives for their use and subsidies to offset the added expense of converting from fossil fuel to renewable energy.

The flow of renewable energy involves phenomena that occur naturally in our world. Tides, sunlight, wind and heat derived by geothermal occurrences all provide renewable energy. Each of these energy sources is unique both in where we can use them and how.

Most technology that converts renewable energy into power sources we can use are powered at least in part by the Sun if not directly at least indirectly. The earths atmospheric system stays in such equilibrium that the heat that it gives off radiates into space to an amount equal to the radiation that comes to earth from the sun.

The result of this energy level within the atmosphere is roughly translated to the climate of the earth. The water of the earth, also referred to its hydrosphere, absorbs a lot of the radiation that comes to us from the sun.

Most of the radiation gets absorbed at the lower latitudes of the earth that exist around the equator. This energy gets dissipated all around the globe, however, in the form of ocean and wind currents.

The motion of the ocean waves might have a role in transference of mechanical energy between the ocean and the earths atmosphere by way of wind stress. Solar energy also provides the means by which precipitations is distributed and then tapped by hydroelectric energy projects as well as plant growth that then creates biofuels.

Government Grants for Alternative Energy

Warren Peters

		Title: Government Grants for Alternative Energy

In his State of the Union Address for 2007, President George W. Bush called for a 22% increase in federal grants for research and development of alternative energy. However, in a speech he gave soon after, he said to those assembled, I recognize that there has been some interesting mixed signals when it comes to funding.

Where the mixed signals were coming from concerned the fact that at the same time the President was calling on more government backing for research and development, the NREL, the National Renewable Energy Laboratory of Golden, Colardo was laying off workers and contractors left and right.

Apparently, the Laboratory got the hint, because soon after the State of the Union Address, everyone was re-hired. The second speech of the President's was actually given at the NREL. There is almost unanimous public support for the federal backing through research grants, tax breaks, and other financial incentives of research and development of alternative energy sources.

The NREL is the nation's leading component of the National Bioenergy Center, a virtual center that has no central bricks and mortar office. The NREL's raison d'etre is the advancing of the US Department of Energy's and the United States' alternative energy objectives.

The laboratory's field researchers and staff scientists, in the words of Laboratory Director Dan Arvizu, support critical market objectives to accelerate research from scientific innovations to market-viable solutions. At the core of this strategic direction are NREL's research and technology development areas.

These areas span from understanding renewable resources for energy, to the conversion of these resources to renewable electricity and fuels, and ultimately to the use of renewable electricity and fuels in homes, commercial buildings, and vehicles. The federally-backed Laboratory directly helps along the United States' objectives for discovering renewable alternative fuels for powering our economy and our lifestyles.

The NREL is set up to have several areas of expertise in energy research and development. It spearheads research and development efforts into renewable sources of electricity; these would include such things as solar power, wind power, biomass power, and geothermal power.

It also spearheads research and development of renewable fuels for powering our vehicles such as biomass and biodiesel fuels and hydrogen fuel cells. Then, it seeks to develop plans for integrated system enginnering; this includes bringing alternative energy into play within buildings, electrical grids and delivery systems, and transportation infrastructures.

The Laboratory is also set up for strategic development and analysis of alternative energy objectives through the forces of economics, market analysis and planning, and alternative energy investment portfolios structurings.

The NREL is additionally equipped with a Technology Transfer Office. This Office supports laboratory scientists and engineers in the practical application of and ability to make a living from their expertise and the technologies they develop.

NREL's research and development staff and its facilities are recognized for their remarkable prowess by private industry, which is reflected in the hundreds of collaborative projects and licensed technologies that the Laboratory now has with both public and private partners.

Uncovering Details Behind Commercial Energy Drink Success

		Title: Uncovering Details Behind Commercial Energy Drink Success

Low on energy?

Many individuals are experiencing low energy levels. Even if you ate more than what is necessary during breakfast to give yourself the energy that you need for work or other tasks later on, you will notice that it is quite insufficient and you are losing more energy than you have expected. Even drinking more water is still not enough to compensate your body energy loss.

If you are a young individual that is quite hyperactive in performing tasks whether in school or office, you need some energy booster to replenish every calorie of energy that you are using in performing your tasks and activities. In this case, you might try drinking commercially-available energy beverages.

Energy drinks are different compared to other beverages such as soft drinks or soda. It is intended for replenishing lost body energy through supplying legal stimulants, minerals, and vitamins (particularly Vitamin B) that are included in the ingredients.

It was developed primarily because of the demand of many individuals (especially those who are engage in hard work and other energy-consuming activities) for a supplement that will not only provide additional nutrients to their body but giving a boost to energy as well. Because of their tight daily schedules, most of them are left with less time on eating and sleeping, which are natural tasks to replenish lost body energy.

Some of these common energy-boosting ingredients are as follows:
