Converting the up-front investment into a series of payments provides an estimate of the annual cost of the system. It is equivalent to repaying a 100 percent loan over the life of the. Rowing rate and the rate that could be earned on the farm's equity capital. Electricity usage of 0.01 kilowatt-hour (kWh) per point of moisture. To find your heat use you must first deduct non heat use, then convert to BTU's then divide by heating degree days and the square footage of your home. Start by getting your total. So for each hour of use the fluorescent bulb saves you 47 watts at an average electric rate of.15/kilowatt or.00705 cents. Doesn't sound like.

This is the history of energy. In the beginning, we just had human power; whatever we could do in a day was what got accomplished. We carried things or used simple machines. How much work can a single human accomplish if you work all day? Well, for example, take a look at this picture here. There's a young lady carrying water in her village. That's a current picture, that's modern photography. So one of the things we'll look at is not only the past, but the fact is that many people around the world, over a billion still live on human power today, or simple machines. 2 Before we get started, there's some things we have to figure out. This is a science based course, so we have to figure out what a unit of power, energy, what are these things that we, we deal with all the time and never stop to think about? But a watt is a unit of power, or energy per unit time. The unit of energy is a joule. You know, like scientists do, they always figure out something to name after themselves. Actually, they didn't, it's the people who follow on after them, they thought so much of the people, Watt, Joule, that they named units of power and energy after them. So a watt, when you look at it, is energy per unit time or a joule per second. So it's instantaneous rate, how much can somebody do at a particular point in time. Now if you look at an average human, If you work all day, an average human can work at a rate of 75 watts, or power output. Now that's an average human. That's not an athlete that's really in training and can jump and leap tall buildings in a single bound, or things like that, that's an average human. So let's break this down in units. A daily output is 75 watts, or joules per second, a watt is a joule per second. Now, if we convert that time, 3,600 seconds in an hour, we can get rid of that time in the bottom. And then, an average workday of eight hours, you can figure out the average daily output of a human, which is 2.16 megajoules were the M stands for mega or million. So 2.16 million joules per working day is an average human being. 3 Now another way to look at that is something that some of us might be more familiar with is that the energy use if I save for instance a light bulb. So look at a 100 watt incandescent light bulb. Now this is before we get into the next module, so it's not an energy efficient light bulb yet. Let's look at the old fashioned incandescent light bulb, the 100 watt. Now how much energy would we use in a 10 hour period? Well 100 watts times 10 hours is equal to a 1000 watt hours. Now watch the units very carefully. This is where a lot of people get tripped up. It is not watts per hour, it's watt hours. It's on the same line. So if you look at the units, a watt as a joule per second. If we multiply this by ten hours with a suitable conversion, 3600 seconds per hour, the time cancels out so we're left with joules or energy. So when you buy a kilowatt hour from your utility, you're in effect buying a block of energy. That's all we're doing there, is buying a block of energy. So on a human scale, an output of seventy-five watts for eight hours, yield six hundred watts per day of 0.06 kilowatt-hours per day. 4 So we worked this way for many, many years, just human power. And you know, I can imagine the first person looking over there after a long day at work and getting kind of tired and thinking to himself, man if I could just get this cow to work for me things would be a lot better. So that's what they did, they harnessed a cow, an oxen, a farm animal. Even before they had the farms they thought about domesticating and harnessing an animal to help human beings out. The problem is that early on, these early harnesses did not effectively transfer the power from the animal to whatever's being pulled. So the early harnesses made a cow or oxen worth about four humans. And at four humans, it wasn't worth the prevailing practice of just enforcing labor so what we did was that didn't change practices for many, many years. We still worked on that. 5 So what happened next is that we come up with a better harness where the cow was worth about six human beings. At that point, domesticated animals really took off and we started harnessing simple machines. These, a picture right here is two donkeys, looks like from the ears, there pulling a disc harrow with the farmer sitting on a seat right there. So we tried to harness our animals to help us out. So let's take this further and make a, an example that kind of leaps forward in class a little bit. But just look at the US, for example; we spend and use about 18 and a half million barrels of oil a day in this country. Okay, and a barrel's 42 gallons. You find out that a gallon of crude oil's worth about 141,000 BTUs, or British Thermal Units. You can do that in mega joules also. But you break that down, do the proper conversions, and find out that, that oil consumption is worth about 2.43 gallons per day per person in the country. And if you look at that, I gotta look down at my notes here 'because I couldn't remember all these things at once stuck in my head. But that allocation of oil to each person in this country is equivalent to about 166 humans, output of 166 humans per day. So that would be like harnessing 166 laborers to do what you need to do, to have done during the day regardless of how you wanted it done, whether it was going to the store in your car, or air conditioning your house. But, in terms of comparison, that is, concentrated energy. 6 But, if we look around the world, today, we still have many places in the world that use human powered activity and animal power activity for the vast majority of what they do in a day. Here's two oxen here pulling a plow on the left hand picture. On the right hand picture are two farm carts. You can see some of the modern technology, the rubber tires, axles, metal, but still, it's a farm animal pulling a farm to market type of cart. 7 We progress in our history of energy, we started using wind power for things. This is a, a scene probably in the low countries in Holland where you use wind to pump water and to drain the land so you could farm it. And in the front you have a cart pulled by, it looks like a dog. So we harnessed, harnessed very many different animals to do our work for us over time. And now we move on to physical attributes of the planet we live on, like wind. 8 The picture on the left is a, Jacobs Aeromotor the Great American Desert is what we called that originally when we explored that region in the United States of America, but we found out that desert actually had very, very good soils, and underneath the desert was a large aquifer. So we put these early wind powered pumps in there, to pump water out to provide water for our earlier farms and farm house uses. Now, an early version of that if you look on the right is a Persian wind mill. Now that Persian wind mill's probably 1500 years old, it's a vertical axis, different from the others and wind can only approach from one direction. That's in an area where you might have tradewinds that are very predictable, always coming from one direction. 9 Water power was the next thing to be harnessed, where we have examples of water wheels being in use. There's an overshot, and I think the one the top picture there might be stream flow, where it's actually just the flow of the stream that causes the water wheel to work. And that can be used to saw wood, to grind grain, to provide power for many different uses. 10 Time marches on. We can start putting these outputs in comparison to what we talk about in early human output. Early windmill mechanical outputs, about 1.5 to 10.5 kilowatts, early water wheel mechanical output is 1.5 to 3.8 kilowatts. Again, many, many times more than a single human could do during a day. Now, the wind power strange looking thing right next to my elbow, is a, guy by the name of Brush invented a windmill to produce electric, not wind mill, but a ind powered generator to produce electricity in 1888. The output was 12 kW, massive improvement, but still nowhere near what we do today. 11 Now, use wind power, use water power, now somebody comes up with an engine, an actual mechanical engine. The first engine in production use was a Newcomen steam, steam engine in 1712. Newcomen developed a very simple steam engine that basically used an up and down motion to pump water out of coal mines. Didn't care about the efficiency, which was about 1%, because it's a coal mine. All you did was dig more coal out of the coalface and shove it into this pump to pump water out of the mine. Well, along comes Watt, again we named that unit of power after that, the watt. Along comes Watt, and his partner Bolton, who somehow in the tides of history have been forgotten, but it's the Watt/Bolton steam engine. Massive improvements in terms of separating the condensing and the heating part, so you have a cool part and a hot part. And they separated the two, so you could do them more efficiently and more quickly. Also, replace the up and down motion with a rotary crankshaft to give us rotary motion. Now rotary motion is important because the next thing you do with rotary motion, is start making things that can move. 12 So, early power summary, we've got a working laborer, 0.075 kilowatts, an Ox, 0.45 Kilowatts, early wind power one 1.5 to 10.5, early water power is 1.5 to 3.8 kilowatts, Newcomen steam engine is 15 kilowatts, Watt/Bolton steam engine now 25 kilowatts. But the next thing on our ticket is a diesel engine, that's 10 kilowatts. So we're starting to move on to magnify human power. 13 So let's see what these numbers mean in comparison to working laborers. So an ox is equal to 0.45 kilowatts, human being was 0.075. Simple division, back to our onversion. Six workers equaled about one ox. The largest early wind power devices represent the output of 140 laborers, 10.5 kilowatts to 0.075 kilowatts. The output of a Watt/Bolton stream engine was equivalent to about 333 laborers. Now, flash forward ahead to us, an automobile with about 134 horsepower engine, I picked that because that's equal to about 100 kilowatts, is equivalent to the output of about 1300 individual laborers. So remember that the next time you have to go back and get that gallon of milk that you forgot at the store. It's like harnessing 1300 individual laborers just to get you out to get that gallon of milk, that you forgot.

Generator Buying Tips

Whether you looking for a : standby generator or a portable generator or inverter Generators or a quiet generator or a quiet portable generator or a camping generator, or a PTO Generator (Power Take Off), you will find a great selection of the best generators on this website. Before you start your generator adventures there are a few things you must know.

Things to Know Before You Buy

There are a two basic numbers you will need to determine before you buy a generator : what would you like to power? and how many watts do you need? Since you are reading this, you are already ahead in the game; you are getting informed and taking control by gathering information.

Spending a little time with a calculator in hand on this page will lead you to your perfect generator. This buying guide will make your buying process relatively pain free. So ready :

What Size of Generator do I need

STEP 1. What would you like to power ?

Are you you planning a tailgate party or is it for camping ? Do you want to use it as an emergency backup. Depending on your requirements, decide on a list of appliances which your generator will have to power. Use this table below to select the appliances you want to power. Then move to SETP 2 which is below the table.

STEP 2. How many watts do you need ?

After Step 1, you should have a list of appliances devices which your generator must power. Here is an example of what your list might look like :

The Generator Sizing Calculator says you need a 4675 watts generator. Your best choice would be the next largest size which would be 5000 watts or 5KW generator.

Budget for Generator

Now that you have established your generator size, you need to make sure your budget will be able to buy that size of generator. Sometimes you might have to compromise and buy a lower power portable generator instead of a standby generator that you might have established to be your required generator size. A Transfer switch is and additional item that you will need to safely power the circuits in your home. Would you need the services of an electrician to install your generator or are you a proficient DIY er.

Included Items with Generator

What about the items in the generator package. Is the warranty and maintenance package upto snuff ? You need to determine if the generator comes with power cord, oil, wheels, a cover, a funnel etc. And the transfer switch is very important. Does it come included? How much for installation ?

Different Generator Types

The two main Generators types are the : Standby generator and the Portable generator . There is another generator type know as Inverter Generators which are quieter and are gaining popularity. If you are environmentally conscious you might like to go for a Solar generator. There is a whole section on this website devoted to Solar Generators.

Standby Generators: The largest class of geneators starting at about 7,000 watts and going upto 20,000 watts or more. These standby generators with capacities from 7KW to 20 KW typically offer 24 hour home blackout protection.

They are professionally installed with Transfer switches and automatically start during a power outage and are able to provide your home with enough power to either meet all your needs or your critical needs depending on the size of generator.

The larger standby generators are called whole home generators or Home Standby Generators and draw fuel from existing natural gas or propane supply lines. They are usually installed on concrete pads and are enclosed with generator covers.

They are permanent installs and cannot be moved around They cost between $3000 to $ 40,000. Installation usually requires a town permit.

Smaller standby generators can cost between $3,000-$15,000 and are usually standalone units that don’t require professional installation.

You should check their dimensions and power output carefully before selecting a unit. The smaller standby generators are best for job sites as they offer mobility are powerful enough to run a variety of tools.

Make sure you use the Generator Sizing calculator to cover your running and starting watts needs. Construction Professionals may also like to check for features like auto-idle technology, roll cage frames and flat-free wheels.

The smallest generators are the Portable Generators that are priced between $100-$3,000 and range in power from 1000 to 10,000 watts. They are best used for leisure activities or for a few hours of backup during an outage.

Choosing a portable generator boils down to making choices about their wattage, how long they are able to run and finally their size and portability.

Depending on your needs you might want to make sure they support outputs such as the 120-Volt RV Outlet, 12 V DC and USB in addition to standard AC outputs.

The final class of generators are the Inverter generators which are seen more in use among the camping boating and RV communities. Inverter-Generatorswith their quiet clean operations and relatively small sizes make them a good choice for your next tailgating party.

Inverter generators can cost anywhere between $150-$6,000. Power ratings of inverter generators stretch from 500-3,000 watts. Guitar center gain program website. They make a good choice for their clean power, efficiency and size.

A great benefit of the Inverter Generators is their low Total Harmonic Distortion (THD) making them super safe for all electronics. If their smaller wattage deters you, you might consider buying two and connecting them with a parallel kit.

Generator Safety

Make sure you read the owner’s manual and instructions and carefully follow all instructions and warnings in order to safely start and operate the generator. Some standard operating rules are :

You must not connect your generator directly to your home’s electrical wiring, especially not to a regular outlet. This can ‘back feed’ onto the power lines and injure neighbors or utility workers.

Use a transfer switch.

Have proper grounding for your generator and follow all township guidelines and permits.

Never run a generator indoors

Don’t run in an enclosed area such as garages.

Operate outdoors and away from windows, doors, vents and crawl spaces

Make sure there is adequate ventilation around the generator

Open doors and windows with a running fan will not provide ventilation.

Generator should be on a flat surface and not be exposed to excessive moisture, dirt, dust or corrosive vapors

Btu To Btu Hr Conversion

The fuel tank must not be overfilled. There must be room for fuel expansion.

Only add fuel while the unit is cold and never while it is running or hot.
