World Energy Consumption

This chart shows how much energy is used in the whole world each year:
Energy use (TWh)
YearFossilNuclearRenewable
199083,3746,11313,082
200094,4937,85715,337
2008117,0768,28318,492
Change 2000-200822,5834263,155

 Here are some ways that you can reduce the amount of energy used per year, which contributes to global warming:

          1.  Turn out the lights when you are not in the room.
          2.  Unplug everything that is not in use or is not used often.
          3.  Use the heater in your house less, wear warm clothes more.
          4.  Set your computers to sleep or hibernate when not in use.
          5.  Use appliances efficiently.
Go save the planet!

An Environmentalist's View on Cars Just about everyone drives almost everywhere in cars!  Considering that an average car emits about 6 tons of carbon dioxide every year.   Knowing that global warming is mainly caused by carbon dioxide, that can't be good!   This photograph shows a car emitting a large amount of smog, contributing largely to global warming, This chart shows how Americans commute to work: The amount of Americans that commute to work by driving alone is very believable, considering the large quantity of cars that are on roads and highways all of the time, but also thoroughly disgusting!  Cars contribute to a very high percentage  of global warming  by emitting carbon dioxide, smog, smoke, and other harmful gases into the air and are driven almost everywhere by most of the U.S. population. Cars produce a lot of smog, which hurts living conditions and creates numerous health problems, such as asthma and even l...

Environmental Affects of Eating Animals 7.3 million people, or 3.2 percent of U.S. adults, follow a vegetarian-based diet.  About 1 million people, or 0.5 percent, are vegans, who consume no animal products at all. Being a vegetarian myself, I know all about it.  My mom used to be vegan, so I know all about that, too.  Vegetarians do not eat any meat while vegans don't eat any animal products at all, including dairy and eggs.  One of the questions I get asked most often is "So, what  do  you eat?" The answer to that is basically everything that isn't an animal.  You can eat fruits, vegetables, grains, tofu, dairy, eggs, and everything that didn't have a face.  There is also processed soy products like vegetarian sausage, bacon, burgers, and chicken. Some people who eat animals probably don't even know exactly what they eat when they scarf down a hot dog.  Most likely they think "I'm just eating meat" or "I'm just eat...

The Hole in Our Ozone Remember that ozone hole that forms above Antarctica every year? Well, according to NASA, this hole is slowly shrinking every, this year's smaller size due to the usual variations of Antarctic weather conditions. In 2006, the ozone hole had reached a record size, more than 11 million square miles. Ozone is a gas made up of three oxygen atoms (O 3 ). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun’s ultraviolet (UV) radiation. In the lower atmosphere (the troposphere) near the Earth’s surface, ozone is created by chemical reactions between air pollutants from vehicle exhaust, gasoline vapors, and other emissions. At ground level, high concentrations of ozone are toxic to people and plants. Scientists don't expect it to be completely healed until 2065, but if we do our part, we could probably speed up the process. "With ozone depletion, mankind has demonstr...
