HOW MUCH CARBON DOES YOUR COUNTRY PRODUCE?
Breathingearth is a fabulous site that offers an interactive map of carbon emissions, birth rates, and death rates in the world. It can be truly frightening to let it run for a while and see how much carbon and people we are adding to the world. Check out the different countries by highlighting them.

WHERE TO FIND RARE EARTH ELEMENTS
By Ainissa Ramirez | NOVA https://www.pbs.org/wgbh/nova/article/rare-earth-elements-in-cell-phones/
Every time I see a commercial for a new cell phone, I feel a bit nauseous. I love a new cell phone just like the next person, but because of my training as a materials scientist, I feel like a worker in a sausage factory. Cell phones, like sausages, may be great, but you don’t really want to know what it takes to make them.
Our lust for new devices isn’t sustainable, at least not yet. Some of the key materials used to make them, mainly rare earth elements, are in tight supply, in part because…>> www.pbs.org
THE SURPRISINGLY LARGE ENERGY FOOTPRINT OF THE DIGITAL ECONOMY [UPDATE]
Our computers and smartphones might seem clean, but the digital economy uses a tenth of the world’s electricity — and that share will only increase, with serious consequences for the economy and the environment.

Which uses more electricity: the iPhone in your pocket, or the refrigerator humming in your kitchen? Hard as it might be to believe, the answer is probably the iPhone…>> science.time.com
VAMPIRE ENERGY: ESSENTIAL ANSWER
Believe it or not, there are vampires lurking in your house at this very moment. Not the bloodthirsty sort from Twilight, but energy vampires: appliances that silently suck electricity from your wall outlets and discreetly inflate your power bill. The small rechargeable appliances you mention are all guilty of wasting watts, as are other common household electronics like computers, televisions and microwaves. Even when turned off or in standby mode, these energy vampires continue to feed on the lifeblood of your electricity. What’s to be done?…>> alumni.stanford.edu
MICHIGAN State Profile and Energy Estimates
Resources and Consumption- eia.gov/state
(How is your state doing)
Michigan has substantial natural gas reserves — more than any other State in the Great Lakes region — but is relatively limited in other energy resources. The State’s Antrim natural gas fields in the northern portion of the Lower Peninsula are among the largest in the United States. Michigan has some renewable energy potential, particularly from…

Only 10% of energy in a light bulb is used to create light. Ninety percent of a light bulb’s energy creates heat. Compact fluorescent light bulbs (CFLs), on the other hand, use about 80% less electricity than conventional bulbs and last up to 12 times as long.g
Refrigerators in the U.S. consume about the same energy as 25 large power plants produce each year.e
Google accounts for roughly 0.013% of the world’s energy use. It uses enough energy to continuously power 200,000 homes.a
According to Google, the energy it takes to conduct 100 searches on its site is equivalent to a 60-watt light bulb burning for 28 minutes. Google uses about 0.0003 kWh of energy to answer the avenge search query, which translates into about 0.2 g of carbon dioxide released.a
On average, one pool pump consumes electricity equal to 44% of the annual electricity consumption of a typical California household. There are over 7 million pools in America.h
In the average home, 75% of the electricity used to power home electronics is consumed while the products are turned off. The average desktop computer idles at 80 watts, while the average laptop idles at 20 watts. A Sony PlayStation 3 uses about 200 watts and nearly as much when idle. Idle power consumes more electricity than all the solar panels in America combined. https://www.factretriever.com/energy-facts

Worldwide, people use an estimated 1 trillion plastic bags, which equates to 100 million barrels of oil. Approximately 380 billion of those bags are from the U.S.
Because landfills are so densely packed, much of the degradation that occurs is anaerobically, or without air. Anaerobic processes create a tremendous about of methane gas, which is a major contributor to global warming.
In the U.S. alone, people throw away 2.5 million plastic bottles per hour. Each one takes 500 years to decompose.
Americans throw out enough bottles and cans to reach to the moon and back—20 times.
The U.S. recycling rate is about 34.5%. If the rate goes up to 75%, it will be like removing 50 million cars from U.S roads.
Over 1 million seabirds die each year from ocean pollution.
