Special gadgets and energy: How to save electricity in your computer

Formerly it was said that the computer just consuming electricity. Lie. Assuming that an oven has an output of around 3,000 watts, a powerful computer can easily reach 300 watts, approximately one-tenth. Is it too little? Note that usually turn the oven on time, but many computers are the clock running.

If you're wondering what to do to spend less energy on your computer then you're in luck: Here's the most important aspects to achieve and get to reduce your energy bill. If you also do special event to our other energy saving then you are guaranteed success. In computers traditionally used power (W, W) and not kWh (kilowatt hour) as the unit of measurement of what you might spend a computer.

Manufacturers of components (microprocessor, graphics card, etc.) Usually indicate the TDP (Thermal Design Power) of his invention, thus indicating the maximum power that can handle physically without fear of breaking. While that can be given if the power is greater, is unusual. For this reason we take into account the power meters, small devices that are placed between the connector and plug and tell us many parameters such as the very power, voltage, amperage and even spending money equivalent consumed in a time interval, should offer a choice - is often the case - and be properly configured.

There are better and worse, like everything, but between 20 and 30 euros and you can purchase a sencillito to basics. Obviously it does not stop here: use it, study the results, write it down and compare. You bear more of a surprise. For example, my current monitor, a Dell SP2309W, has a power of 35-40 watts in operation and 8 watts in standby.

A little? I certainly will not. If a component is consumed as a beast graphics card, one of the most known and most often studied their choice. Little we can do if we already have a computer, but if we are looking a new one - or want to update we already have - while we save a few euros, attentive.

The more lavish graphics cards are often the largest and have ventilation systems that partitioning larger. A simple and effective trick is, of course, choose a model restrained but we serve. Obviously we will yield vital factor: the higher performance offered consume more, and vice versa.

This is our next point. It is the ultimate in energy saving on a computer: the more powerful the more energy spent. We could say much more about it but since then this phrase is applicable to virtually all current settings. Of course, if we save this is a problem because we will always strive for the best team in terms of performance offered, so that after all the users see and suffer.

Therefore we must be clear about what our minimum requirements and what we really need power, I assure you that a huge part of the computers that are around the world with dedicated graphics cards do not. We have already noted that little can do with your current computer beyond turning off the screen to avoid small consumption but which together can be important, or completely unplug the tower which happens a bit the same.

But it is best new computers think what we really need, and as closely as we can to what we think about it. There are huge differences between a normal desktop computer and a HTPC, for example, or between a laptop. Precisely laptops are a good idea to save, not just get to minimize the electricity bill but also in cables and space.

If you want to consume less energy and does not need a lot of machine, a laptop can be an interesting option. Note: the supercomputer of the first image is owned by IBM and Watson ran over him, the Artificial Intelligence software that managed to win the game show Jeopardy in the United States.

It is based on the Blue Gene architecture that may sound to you by Deep Blue, another supercomputer that defeated in 1997 - some say trick - the world chess champion Garry Kasparov. Supercomputers consume vast amounts of energy not only for their hardware - which in recent years is trying to do a lot more efficient - but also for the enormous dissipation and ventilation systems required.

The current world's most powerful supercomputer, the Tianhe-I, has energy costs (including computer and all cooling systems) that are estimated at $ 20 million annually. Buzz In Tech News | Special energy savings.
