Hey Mr. Green,

Q: I've read that we waste a lot of energy with computers. How much do we waste, and what can be done to make things more efficient?

—Samuel, Denver, CO

A: The EPA has updated computer standards on a regular basis for the past 25 years, and each revision has marked a reduction in power consumption. The increasing use of laptops and other smaller devices, which need a lot less power than desktop models, has helped limit total energy consumption. Nevertheless, the EPA says we still waste at least a billion dollars worth of electrical power a year simply by running less-efficient computer equipment. This waste reaches the equivalent of around 15 billion pounds of annual greenhouse gas emissions, or as much as 1.4 million motor vehicles. But the total waste may be actually much greater.


Simply by activating power management on your computer you can save anywhere from $10 to $100 a year. For instructions on how to do this, visit the EPA's "Activate Power Management on Your Computer" page or ask your service vendor to make sure your machines are configured to take full advantage of these sleep features. Also, deploy "smart" power strips that cut off power when you're not using other devices connected to your network.

Consolidate printers: You can eliminate printers, share work-group printers, and use multi-function devices instead of individual printers, copiers, fax machines and scanners. If you still have non-networked printers or make wide use of stand-alone copiers, fax machines and scanners, printer consolidation could save a bundle: between 30 and 40 percent or more.

Global consumption of beef, lamb and goat is expected to rise by almost 90 percent between 2010 and 2050. But that doesn't mean you need to eat more meat. In fact, recent news from Washington gives you even less confidence in your meat: Pork inspections may be taken over by the industry itself, if a Trump administration proposal goes into effect, putting tests for deadly pathogens into the hands of line workers.

The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.

Michelle Pfeiffer wants to change that.

The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

We know that people power can stop dangerous fossil fuel projects like the proposed Line 3 tar sands oil pipeline in Minnesota, because we've proved it over and over again — and recently we've had two more big wins.
