Fossil fuels, for example, are being consumed at exponential rates and are not going to be replenished any time soon. That’s the problem with many of today’s common energy sources; they are highly nonrenewable. For an energy source to be sustainable, it must also be renewable. It must be able to be used efficiently without being depleted. Wind power is a great example of this, because as far as we know, wind isn’t obtained from some limited reserve--it’s available in endless supply so long as there are differences in temperature from one area of the atmosphere to the next. Many similar forms of renewable energy are starting to come into effect, but not quick enough and not on a large enough scale. The main reason for this holdup is because of how deeply rooted the world’s population is into using old, nonrenewable energy forms. To so simply replace every gas-guzzling car with a solar powered one is easier said than done. Jobs would be lost from the collapse of traditional car markets, the economy would lose some stability, and renewable energy sources are not cheap. Progress is being made into simplifying the implementation of and access to renewable resources, but there is still a lot of work to be done. While that work is being done, the nonrenewable energy sources used today are still problematic and contribute heavily to other areas of unsustainability such as air
