'''What is energy mainly used for?''' Here are some basic categories:<br />

Since most energy consumption is bad for the planet, let's look at how it could be reduced - starting with the biggest pieces of the pie.
 
Most of the world is currently living in '''poverty'''. Suppose every country was as ''developed'' as ''western'' countries: [[energy demand scenarios|Global energy demand could be more than '''double''']]:

This is far beyond today's green energy capacity.
 
===Transportation sector===
 
Energy demand would be different if vehicles didn't run on gasoline or diesel. In general, we'd need less energy to ''power'' the vehicles but more energy to ''manufacture'' them (and later ''recycle'' them at their end of life). Overall, total energy demand would be ''slightly'' less. See [[electric vehicles/energy|this chart]].
 
There are currently some serious roadblocks to making this happen. Read the page on [[electric vehicles]] to see how they could maybe be overcome.


It's quite possible that there's ''no good solution'' for electric vehicles, and the only way to make transportation sustainable is for people to ''drive less''. This goes against suburban culture, but it isn't as hard as it sounds:
{{mbox|Note: These actions are mostly directed at "first-world" countries, which use a disproportionately large amount of energy. In other parts of the world, consumption doesn't necessarily have to be reduced.}}
{{minor|We could probably cut out half of all energy consumption while barely losing any quality of life. It just requires some planning (both individually and as a society).}}

A common misconception is that "saving energy" is all about turning off lights, turning off computers, etc. Those actions are worthwhile but don't actually make a ''big'' difference. '''Other''' personal lifestyle choices do:
