Conservation is the protection and preservation of anything e.g. energy, wildlife, environment, natural resources, historical artifacts, books etc.
not heating space,by watering
The 2 most effective (but most expensive) ways are to replace your heating equipment with a more efficient unit and to insulate & air seal the building you live in.
Otherwise, close off rooms you aren't using and close the vents to them. Be sure to watch for mold, though, which can grow under those conditions. Use a programmable thermostat and turn the temp down when you are away.
According to About.com, about 1/3 of the volume and 1/2 of the surface area of the Aral Sea, located in Uzbekistan, has dried up because of diversion by farmers of the two sources (the Amu Darya and Syr Darya rivers) that feed it.
This is also known as phantom power or vampire power. Even though an electric device is turned off, it is still drawing a small amount of power. A television, for example, continues to draw power so that it can sense the remote control to turn it on, or to keep the time.
Other examples are chargers left plugged in for telephones, video games, etc.
It depends on how many lights you leave on and how bright they are. Just think of it as leaving the water running or something.
Recycling helps the Earth by not producing more waste onto our planet. We are throwing away far too much rubbish.
So save the planet!
In a small paperback book called STUFF The Secret Lives of Everyday Things, copyright 1997 by Northwest Environment Watch in Seattle, WA, authors Ryan and Durning with research assistance by Breslow, Halvorson, and Tohan, state that "Smelting is so energy intensive that aluminum earned the nickname "congealed electricity." Making a soda can of smelted aluminum takes energy equivalent to a quarter-can of gasoline. (Making a) 33-percent recycled can took about a sixth of a can of gasoline ..."
Despite the date of the book, similar numbers should apply today in 2011. If you determine the number of aluminum beverage cans emptied by consumers, you'll see that the following "good" things might occur. The amount of money needed to produce a typical soda can should be reduced, and the savings should be passed on to consumers. Or, because of recycling of aluminum, the cost of a can of soda is lower than it would otherwise be (the package is often more costly than the product itself). Less electrical energy should be consumed to make "new" aluminum products, thus allowing more energy for other uses, and/or hopefully keeping the price of electrical energy at comparatively lower values. One could envision a number of other beneficial outcomes, such as reduced environmental impact because of a comparatively lower demand for the earth's limited resources and the fact that such resources become more difficult to obtain as the earth's more-easily-obtained raw materials dwindle.
One thing about aluminum production that may not be apparent is that aluminum is made mostly from bauxite. This ore consists of aluminum atoms combined (chemically bonded) with oxygen and hydrogen atoms in a low-energy state; in other words bauxite has existed on the earth's surface for a long time like this (instead of "pure" aluminum) because these atoms bound together are a lower-energy state than if the pure elements existed in the same volume.
"Since highly electropositive metals tend to react at high temperatures with most materials, common pyrometallurgical processes cannot be used for smelting them. A straightforward method for producing these metals is first to purify a salt of a reactive metal and then electrolyze the salt for recovery of the metallic element." p.207, Unit Processes of Extractive Metallurgy, by Pehlke, 1973, Elsevier. What this means is that aluminum atoms are strongly attached/bonded to oxygen atoms, and to release the aluminum atoms from bonds with oxygen atoms requires a comparatively large amount of energy from some source. In this case, a large amount of electricity is needed to efficiently produce large amounts of "pure" aluminum.
If you can reuse something, why not? You won't have to waste resources that you don't have to.
You mean nuclear fission I think
An energy broker is a person who helps educate and assist consumers, both homeowners and business owners, in choosing a low cost electric supplier in deregulated states. The broker is a go-between the consumer and the the electric suppliers. When a consumer you helped switches their electric through you, the broker, you earn income. Brokers can also earn money by recruiting new energy brokers. Being an energy broker gives you the opportunity to earn residual income, help people save and/or make money, own your own business and the freedom to work from home at your choosing.
1. The sum of the component voltage drops in a series circuit is equal to the voltage at the source.
Vs=V1+V2+...+Vn (s=source, n=total number of voltage drops in the circuit)
2. The greater the resistance imposed by a component, the greater the voltage drop across it.
Larger resistor=larger voltage drops, Smaller resistor=smaller voltage drops
3. In a series circuit, the percentage of resistance contributed by a component is equal to the percentage of voltage dropped by that component.
yes, positrons were discovered in experiments in the 1930s just like theory had predicted. many other anti-particles have been discovered since.
A combined cycle power plant has multiple thermodynamic cycles. This increases efficiency.
For example, a gas turbine can be used to produce electricity, but only about 40% of the heat is actually converted in the process. 60% of the heat is lost, and in a single cycle plant would be considered waste heat. In a combined cycle plant, that waste heat could be used to drive a second, steam turbine to produce more electricity. In such a case, the efficiency could be increased from 40% to nearly 60%.
It is possible to go further. The waste heat from the combined cycle electric plant can be used to heat buildings, for instance, increasing overall efficiency to more than 65%. This is called Cogeneration.
Like all electrical devices, light bulbs consume energy. Traditional (incandescent) light bulbs work by using electricity to heat a "filament" inside the bulb until it is so hot that it glows brightly, whereas newer "energy saving" bulbs use a different principle entirely (they are rather like a small "strip light" or "fluorescent light" such as are normally found in shops and offices etc)
To get the same amount of light, traditional bulbs use much more electrical energy than the newer type. You might think that this means that by using new-type "energy-saving" lighting you will obviously save energy (and hence reduce your utility bills), but it's not quite that simple. Most of the energy consumed by a traditional bulb goes to creating heat (you have probably noticed that they are too hot to touch). If you have, say, 4 60watt bulbs in your lounge, you are using 4 x 60 = 240 watts of electricity, of which almost all is being given off as heat and is therefore warming your lounge. If you replace these bulbs with low energy ones, that 240 watts of heating will be made up by your central heating system which will "trip on" the radiators, so you will burn extra gas to make up the lack of heating from the lights! So your gas consumption (and your gas bill) will go up as your electricity bill goes down.
This effect is most pronounced in winter, when you are likely to use more lights for a much longer time (because days are short) and less pronounced in summer - but you don't use lights or heating much in summer anyway.
So it's a complicated business, but the point is that if you buy energy-saving bulbs which claim to offer a saving of (say) 100 pounds a year, keep in mind that your gas bill will go up (although not necessarily by 100 pounds) - if you are using a very expensive form of heating you could find that your overall costs actually rise, although this is unlikely. You might well save some energy, but probably only a fraction of what most people expect, and of course most people see the reduced electricity bill and feel good, but don't notice the rise in gas consumption - or even if they do, they don't realise it's because of the new light bulbs!
Conventional personal computers are not of much value in conserving energy. Most computers for energy management are microprocessors used to operate HVAC equipment such as chillers, boilers, rooftops, and terminal equipment like VAV boxes. Usually a single microprocessor operates each item of equipment. Within a given building the microprocessors linked together over a simple network known as RS-485. This is a 2-wire communication bus operating as a master slave.
The most popular building automation protocols are BACnet (ASHRAE) and LonWorks (Echelon) running on RS-485. The key to conserving energy with microprocessors is to use their ability to inter-communicate for sharing operating information. The single most important energy conserving program is that of an operating clock running from a master controller, which can signal equipment to operate appropriately.
Buildings operate in either the occupied or unoccupied mode. Using the master controller (usually another microprocessor but sometimes a personal computer running Windows) various sections of a building can be placed into the occupied or unoccupied mode from a master calendar scheduler. Careful adjustment of the occupied start and stop times offers the single most important energy conserving opportunity for any building.
The second most important consideration is to reduce unnecessary reheating of the supply air. Reheating is a common practice in larger buildings where a single air handler supplies low temperature air (55 degrees typically) to terminal units like VAV boxes. When the boxes squeeze down to their minimum position, usually around 40%, the microprocessor of that VAV box can cause discharge air reheating to prevent abnormally low space temperatures.
Microprocessors, suitable connected over a dedicated network (i.e. BACnet, LonWorks....), can sample space temperatures from various rooms. These temperatures can be used in an optimization algorithm that causes the air handler discharge air temperature to be reset up or down, as determined by the warmest spaces, to minimize reheating.
These are the two most important building energy considerations:
There are two ways of looking at the question, "What would happen if there was no electricity".
What if electricity didn't exist?
What if humans didn't know how to use electricity?
2. Natural gas is colorless, tasteless, AND IS ODORLESS IF IT IS NATURAL, requiring the addition of an odorant [one or more of several "Mercaptans"] to allow olfactory detection [smell] of leaks.
3. When gas from an underground leak travels great distances [underground], the odorant can be "scrubbed out" of the gas, thereby rendering it again ODORLESS, and therefore a severe explosion and fire hazard.
4. Being a fossil fuel, it is carbon based, and its byproducts of combustion include carbon compounds [such as carbon dioxide and/or monoxide] which contribute to the environmentally damaging "greenhouse effect."A:
One disadvantage is that burning it creates CO2 emissions (although not as much as oil or coal), and CO2 is a greenhouse gas. Natural gas itself is actually a very strong greenhouse gas also (much more than CO2 in fact). Another disadvantage is that it can leak and cause fires and/or explosions.A:As noted above, Natural Gas is a fossil fuel. I am skeptical of calculations that it produces less carbon dioxide than other fossil fuels, although it does burn cleanly and efficiently.
In some places, Natural Gas is considered a waste gas, and excess methane is just burnt in the atmosphere without using any of the energy it carries. For efficiency, we should be utilizing all of our fossil fuel hydrocarbons.
Some communities are now investing in recovering natural gas from garbage dumps and farming for energy production. There is more of this that we could be doing.
As far as fueling automobiles with either Compressed Natural Gas (CNG) or Liquid Natural Gas (LNG), the refueling process is slow (slower than using propane), and high pressures are required. And there are dangers of carrying around CNG or LNG tanks in vehicles.A:If we are to believe scientists concerning global warming, we need to look at the two products here. Natural gas is mostly methane (as previously pointed out). Natural gas also escapes into our air naturally. Methane is many times more of a forcing agent in terms of green house effect. Converting methane into Carbon dioxide (a less substantial green house gas) would reduce our overall forcing in terms of real forcing.
There are several advantages to using compressed natural gas (CNG) to power vehicles. First, it is the cleanest burning fuel available. This reduces harmful emissions, which helps air quality. Secondly, there is an abundance of natural gas right below our feet. Increasing the production of natural gas would make the US less reliant on foreign sources for its energy, which would also help its national security. Third, as a result of the abundance of natural gas, it is much cheaper than diesel or gasoline. There are many areas throughout the US where natural gas is close to or less than $2 per gallon.
A: The gas orduces lots of energy and is easy to transport using pipelines.
D: It produces more pollution than oil and if it leaks natural gas can cause a big explosion and/or fire
Advantages of natural gas:
- It is a very clean burning fuel
- There is an abundance of it throughout the world - the U.S. has the 6th largest reserve of natural gas in the world
- It is about half the price of gasoline
- It can be used in vehicles and is very efficient
- It is used to heat most homes
- It is easy to recover it from shale
Disadvantages of natural gas:
- There are only about 1,000 fueling stations across the U.S. open to the public
- There aren't very many cars that use it yet
One advantage of natural gas is its abundance in the U.S. Our country has the 6th largest natural gas reserve in the world. Natural gas also has the advantage of being the cleanest burning fuel available.
it can help keep other gases from the destroying the atmosphere(good for the enviornment)
and it also made vampires decay in the caves back then so there arent any more alive...(or are there?)
Also natural gas is used for fuel... and other things that have to use power
Natural gas is a carbon fuel so burning it generates the greenhouse gas carbon dioxide. However this produces less carbon dioxide than the same amount of energy from burning oil or coal, so natural gas is slightly cleaner than other fossil fuels.
The sun is not "attracted" to dark colours. Dark colours simply absorb energy more efficiently than light colours. Light colours reflect the energy away, so they don't heat up the way that dark colours do. To say that dark colours "attract" the sun is simply an incorrect way of saying it.
By removing the power source if you are not using it
There are dozens of ways to cut energy costs on a daily basis, but here are five of the most basic:
United States use 43% of world's gasoline.
No one answer, since there is no one powder, and it varies depending on single base or double based powders, but 1000 to 1500 times roughly.
