However, you can also choose to run your PC 24/7, contributing your PC’s processing power to distributed computing projects 10 Ways To Donate Your CPU Time To Science 10 Ways To Donate Your CPU Time To Science Read More . With these projects, your PC can help fight cancer, test climate change models, or even search for alien life.

However, computers use power when they’re on, and they use more power when their CPUs (or GPUs) are going full-throttle. Participating in these projects will increase your electricity bill An Energy Saving Masterclass For Computer Users An Energy Saving Masterclass For Computer Users About 10% of an average home’s power use is dedicated to computers. That is the average for the United States, however, and is only an average. Users who are computer enthusiasts may find that their... Read More .

How Your PC Can Help

Many important projects need a large amount of processing power. Rather than rent expensive supercomputers – which may not even provide enough processing power if they were running 24/7 – these projects ask for volunteers to contribute their PCs’ processing power over the Internet.

You can download and run a program that makes your PC part of the distributed computing project. The project will use your computer’s resources when you aren’t using them – when they’d just be sitting idle – to help calculate many small tasks. Your computer will receive units of work to do from a central server, perform the work, and then return the results to the server over the Internet.

One of the more popular projects is Stanford’s Folding@home, which simulates protein folding. Protein folding data is important to medical research, and has implications for everything from cancer to Alzheimer’s disease. Since the Folding@home project started in 2000, 109 scientific research papers have been produced from the Folding@home data.

Sadly, as they’re slower, they’ll also produce less results for the project.

Running your computer’s CPU or GPU full-throttle will also produce additional heat. If you’re in a hot area, you may have to fight that by paying more for air conditioning. (Even if you’re in a cold area, a computer isn’t the most efficient source of heating.)

Wear & Tear

Wear and tear is a worry when running distributed computing projects. Your CPU will be generating a large amount of heat inside your computer’s case, and this heat can damage components. Theoretically, a CPU should be able to handle running at 100% for a long time. However, in the real world, some CPUs may be shipped with inferior heat sinks that aren’t good enough to disperse such a large amount of heat.

Some computers may not have proper cooling. For example, many laptops won’t be able to handle being run at 100% 24/7. They’re just not designed to disperse the heat properly and will overheat.

With a solid desktop computer that has proper cooling, you shouldn’t have to worry about wear and tear. If you have a sleek ultrabook What Is An Ultrabook & Can It Succeed?

A Note About Bitcoin Mining

Some of the less-philanthropic of you will be thinking about mining bitcoins for yourself guiminer - An Extensive Tool For Bitcoin Mining guiminer - An Extensive Tool For Bitcoin Mining As of late there's been a been a great buzz going around about Bitcoin, the latest P2P digital currency. One of the main activities of getting Bitcoins is through a process called mining. No need... Read More instead of using your PC for the greater good. However, you shouldn’t bother. A CPU mines bitcoins so slowly that you’ll spend more money for electricity than you’ll gain in bitcoins. A computer’s GPU is much faster, but GPU mining appears no longer profitable for most people, either. ASIC mining has replaced both GPU and CPU mining.

If you have a fast GPU and cheap electricity prices where you live, GPU mining may still be profitable for a few months at most, but don’t count on it. The Bitcoin mining rush is over, at least for people with standard computer hardware.

So What Should You Do?

Whether you want to participate in distributed computing projects is a personal decision. Joining a distributed computing project will do some amount of good, but it will cost you additional money in electricity. A newer, faster computer will do more good for the same amount of electricity than an older, slower computer.

One thing’s for sure: You shouldn’t be mining bitcoins with your PC. The payout is so low that you’ll spend more on electricity than you’ll gain in Bitcoin. You’ll effectively be transferring money from your electric bill to your bank account, losing some in the process.

If you’re going to use your computer’s idle power, do it for the greater good.

    I have my computer in the office on Stanford’s Folding@home at night time. Often forgot to plug in my laptop at home but I'll try to do it more often. Yes, it cost you a bit and you use a natural resource why you have to think about where your electricity comes from - more coal or oil use is not good for the nature.
