Coal Power Online

Liam G asked:


We are all aware of the importance of electricity and the elementary role it plays in our day to day lives. It is only when there is a power failure that we truly appreciate the effect it has on our lives.

It all starts with a source of energy, and within the UK 74% of this energy comes from fossil fuels, primarily coal, natural gas and oil. Other sources include nuclear power, which supplies 19% of the UK’s energy demand and the following 7% is supplied by other sources such as hydro-dams, wind farms, solar panels etc.

It’s important to note that electricity is a secondary source of energy, meaning it relies on a primary source of energy to be created. These primary sources are the ones listed above, and can further be broken down into renewable and non-renewable sources.

As highlighted a primary source of energy is required to generate electricity, this source of energy is used to superheat water in a boiler to create steam. The steam outputted from this boiler is of such a high pressure that it can be used to turn the blades of a turbine. The turbine works to turn the linear motion of the steam into circular motion. Connected to this is a generator which houses a large magnet surrounded by coiled copper wire, the motion of the blades in turn, rapidly spin the magnet which creates an electrical current in the copper coil.

From the generator the electricity heads to a transformer, where its voltage is stepped up considerably (typically 345,000 volts), which allows it to be transferred a very long distance without any loss.

The electricity is then placed on the national grid, where to begin with it is carried by huge transmission lines, capable of handling the high voltages. Throughout the grid there are numerous step-down transformers which serve to reduce the voltage to a more manageable 12,000 volts suitable for the distribution lines.

Before the electricity reaches your home it is stepped down once more to 240 volts. This takes place in the small transformers that you commonly see at the top of your neighbourhood power line pole.

Once in your home the electricity passes through a fuse box and meter which allows your utilities supplier to calculate your electricity bills. Considering the journey the electricity has to make from the power station to your home, electricity prices are pretty justifiable in that the whole process takes no more than a fraction of a second.

Tommy Johnson asked:


What about a solar power home system? Do you know you can save up a lot of money, once installed? If you are asking yourself how can sun drastically reduce your expenses, you can learn something new today. Learn how to produce your own energy.

In the United States, about 94% of the energy production is made out from petroleum, natural gas, coal, uranium and propane. These are all not renewable sources.

The rest 6% production, is made out from biomass, hydro power, geothermal sources, wind and sun. These are instead renewable forms of energy.

All this means you should start thinking about environment and your future. You should also think about how, a solar power home system, will make you more safe and make you spend much less.

1.4 Kilos of carbon dioxide, per person, per day, is produced when an electric water heater is used, 1.7 Kilos using methane. The use of solar panels, has zero emission of carbon dioxide, and zero emissions of other harmful substances.

Sun is the source of all energy, you can take advantage of this incredible power by starting to use solar panels, a good choice for your house.

Wind also offers a very good resource to use, costs are little and works fine in energy production. Wind turbines, convert the kinetic energy of the wind, into other forms of power.

Fortunately, energy saving habits has started in families; people start buying energy saving products like lamp bulbs, low power devices, home appliances, etc. These habits should be took as an example, if we still love our planet.

If you still think, you do not need a solar power home system, you will lose all the potential of nature and the way it could work for you.

Start now to help global climate stability. Think of energy in a different way.

Lorraine Cohen asked:


In the late 80s, my three friends and I participated in one of Anthony Robbins 5-day seminars on empowerment that included walking barefoot across burning coals. When we arrived that evening, the first sight we saw was fire trucks and medical teams (on call in case of any emergencies). You can imagine what was going through our minds!

For the next five hours (with about 500 people) we experienced numerous exercises in preparation for the fire walk. We focused our mental states to imagine the burning coals were “cool moss.” I admit that I felt some fear. Could I do it? Would I be safe? Would I get burned?

Of course no one HAD to do it. As I watched all of my friends successfully do their walk, I just had to go next. I wasn’t going to be the only one who bailed! We were mentally prepared to imagine (and believe) that, as we walked, the ground beneath our feet was cool moss. Big gulps. Ready, get set….now walk. “Cool moss, cool moss.” I took my first step and kept going until I reached the end. Guess what? No burns. It was an amazing experience.

I’ve looked back over that evening many times to remind myself those things that seem threatening or overwhelmingly difficult CAN BE OVERCOME with the right mindset, support, and resources.

What I’m emphasizing is that things that appear or seem too big to manage might be easier to overcome than you might think. Watch that illusion piece. You know - perception can be a tricky thing. You can see things as problems or opportunities.

Over the next five days, I heard Tony use the phrase, “If you can’t, you must. If you must, you can.” He’s been quoted for that phrase. When I heard him say those words, they really struck a chord in me. I have never forgotten them.

Here’s why that quote has become a ‘powerfull’ mantra for me. Whenever I feel passionate about something or when I feel driven to do something and some resistance or fear pops up, I remember that quote. It helps me bust through roadblocks.

When the need/desire to move becomes greater than the resistance to stay stuck we can move mountains. I call this “tipping the scale.” Many people will push through things that are uncomfortable when the pain of holding on to something becomes so unbearable that they are willing to do whatever it takes to make the pain go away. Pain is a pretty ‘powerfull’ motivator.

That weekend was a metaphor for me - overcoming the illusion of MOUNTAINS that are really mole hills. (That’s one of the reasons I use that tag line in my products!) Now, I pay attention to those times when I have a burning desire to take action in the face uncertainty or fear.

I just remember, “If you can’t, you must. If you must, you can.” While pain is a ‘powerfull’ motivator for change - passion and burning desire is much more pleasurable!

Cool moss……

Here is the transcript of Obama’s statement about bankrupting the coal industry (emphasis mine):

Let me sort of describe my overall policy.

What I’ve said is that we would put a cap and trade system in place that is as aggressive, if not more aggressive, than anybody else’s out there.

I was the first to call for a 100% auction on the cap and trade system, which means that every unit of carbon or greenhouse gases emitted would be charged to the polluter. That will create a market in which whatever technologies are out there that are being presented, whatever power plants that are being built, that they would have to meet the rigors of that market and the ratcheted down caps that are being placed, imposed every year.

So if somebody wants to build a coal-powered plant, they can; it’s just that it will bankrupt them because they’re going to be charged a huge sum for all that greenhouse gas that’s being emitted.

That will also generate billions of dollars that we can invest in solar, wind, biodiesel and other alternative energy approaches.

The only thing I’ve said with respect to coal, I haven’t been some coal booster. What I have said is that for us to take coal off the table as a (sic) ideological matter as opposed to saying if technology allows us to use coal in a clean way, we should pursue it.

So if somebody wants to build a coal-powered plant, they can.
It’s just that it will bankrupt them.

Amazing that this statement by Obama about bankrupting the coal industry has been kept under wraps until this time.

Abhinav Sidana asked:


If you are interested to know how to build your own wind power generators, don’t worry; you have arrived at the right place. You can build your own wind power generators at home and for this you do not require any proficiency in any field. It is quite simple and you can build wind power generators below $200, however if you purchase the equipment from market, it will cost you around $2000.

Wind provides us a renewable source of energy and therefore the energy or the electricity available to us from wind is almost free. We require only an initial investment of $200 and thereafter a nominal maintenance is required and we can generate electricity continuously and of course the amount of electricity generated depends on the wind speed.

People are generating electricity from wind and are saving up to 70 percent of their electricity bills per month and every month. If you live in a windy area and your electricity consumption is less, you can even generate surplus electricity from your wind power generators installed in your backyard. Electricity companies are ready to purchase this surplus electricity, as this is far better than the electricity produced from non-renewable sources of energy such as coal, diesel and gas.

You can build your own wind power generators and you will require a few items such as blades, a tower, a battery, a DC motor and a tail. DC motor should be carefully selected as it is the costliest among all other items and most importantly you should go for quality blades. You can get all these items from a nearby store; however a few items you can make yourself at your home. The next and most important part of building your generator is to assemble them and here you will need a guide.

What’s that smell? Why are we all getting sick?

In a small Island on the great Susquehanna River lie 3 miles from each other, 3 power plants, each with its own pros and cons; the first, 3 mile island nuclear power plant, in Goldsboro, PA - a plant that almost melted down and could have melted all of us down - Unit 1 is still operating as a nuclear plant, while Unit 2 is not a nuclear plant anymore (accident in march, 1979). The second is Conewago Hydropower plant, it is a clean and safe source of energy, and in the case of the Susquehanna River, which is already so polluted, and whose wildlife must be bionic by now, it leaves a small environmental impact. The third and last is Brunner Island Coal Fired power plant, which according to many sources (you can google it - look at results 3 - inf. if you look at results 1 and 2 you will be directed to the operating website, which of course will boast how clean its own plant is - that is BS) is one of the 50 dirtiest, most polluting coal power plant in America.
