The United States uses about 25% of the world's oil energy. It's hard to calculate exactly, but when all other forms (solar, nuclear, coal, wind, natural gas, etc.) are factored in, the overall percentage used by us is a bit less; maybe 22-23%. This only makes sense when one considers that the U.S. (5% of the world's population) produces 20% of the world's economic output, China is second at about 13%. (as of 2007). Additionally, depending on exactly the numbers used; the U.S. is responsible for 20-30% of the world's GDP (Gross Domestic Pro-duct). In addition to product manufacturing, a large portion of our energy use is devoted to food production; before recent increases in Russian grain production that allowed them to be a net exporter, we practically fed the world. With our usage of lighting, computers, large screen t.v.'s, central a.c , etc. just for residential comfort, it's no wonder why the average person living in the U.S. consumes more energy than others. Next time you hear an environmentalist deride the U.S. for her energy use, ask them about what that energy produces. They will have no idea.
Europe consumes around 17-20% of the world's total energy consumption.
1` billion percent!
0.17 % of the worlds population
Only about 15% of Canadians use solar energy. Nikka.
The question is ambuguous. It could meanWhat percentage of the world's coal use is in AmericaWhat percentage of America's energy needs are met by coal.Second, what is America: USA, or, more correctly, North and South Americas
A percentage is always a comparison of two numbers. It is not clear what two numbers (amounts of energy) you want to compare in this case.
im not saying
Actually you can't. At least, if you use the gasoline in a car, a large percentage of the energy is wasted.
90% of athletes use energy drinks because they essentially rely on it to improve their performane of which in some cases, it does.
if we use our resources carefully...and we are aware of just how much can effect the planet...then yes. Nuclear energy can be use das a clean source of energy...and...if were permitable...could be used to produce 16% of the worlds energy
Thermal energy is used in all Internal , as well as in External (old steam engines) , Combustion Engines. That makes thermal energy one of the most usual forms of energy people use. So, from this point it is not hard to use themal energy. Thermal energy has a maximum percetage that can be tranformed into useful work and this percentage can never be 100%. This maximum percentage is described by the Carnot formula.
Well energy is a broad topic, in-terms of oil the US uses the most, roughly 25% of the worlds oil that is produced.
Reducing energy use is called energy conservation and efficiency is the percentage of energy that is actually used to perform work the rest of energy that is '' lost '' to the surrondings.
yes if you place the photo-voltaic cells inside office buildings and instead use inside light not solar or sun light. A great percentage of light in the worlds buildings can be recycled by simple using light energy and not only recycling solar energy but office light also.
Around 75% pf Australia's energy is derived from coal. Well we are starting to use solar energy and Kevin Rudd is push to put limits on how much coal we use.
USA and Canada are the worst of countries. They use the most energy on the planet!!
10% actually seems like a high percentage, but it might be. That is because animals and plants use a large part of the energy for their own maintenance. Only a small part of the energy is stored for future use.
